Morphea (Localized Scleroderma)
Are You Confident of the Diagnosis?
Morphea may present at any age. In children, the linear subtype predominates while in adults’ plaque and generalized subtypes are most common. Morphea occurs more frequently in women, especially in adults where female predominance is marked (5:1).
Morphea is not the same as scleroderma (systemic sclerosis), and it does not become scleroderma. Key differences include presence of the following in scleroderma, NOT morphea: acrosclerosis/sclerodactyly; Raynaud’s phenomenon; antibodies such as anti-centromere, Scl-70, and RNA polymerase; and characteristic internal organ involvement.
Clinical evolution of morphea lesions may occur very rapidly or over months; patients often have a mixture of active and inactive lesions:
- Active inflammatory lesion; plaque with erythematous or violaceous border; may have central white yellow sclerosis and/or indurated border
- Sclerotic lesion; thickened, hardened plaque with minimal erythema
- Atrophic (inactive) lesion; hypo/hyperpigmented plaque with dermal or subcutaneous atrophy
Circumscribed (plaque) : single or multiple oval/round lesions; “superficial” if limited to epidermis, “deep” if extending into subcutis, fascia or muscle (
Circumscribed (plaque) morphea
- Trunk and limbs: Linear lesions may have deep involvement; those on trunk are often misclassified as circumscribed (
Inactive linear morphea/morphea profunda
- Head : Linear lesion on face and/or scalp - en coup de sabre; progressive facial hemiatrophy (Parry-Romberg) - deep facial involvement (
Linear lesions on trunk, limbs, face and scalp.
Generalized: Deep involvement is common (
Generalized morphea (deep involvement is common)
Coalescent plaque: 4 or more plaques in at least 2 of 7 anatomic sites (head/neck, right/left upper extremity, right/left lower extremity, anterior/posterior trunk).
Mixed : Combination of any above subtypes
Expected results of diagnostic studies
Diagnosis is usually based on clinical findings as described above. There are no widely accepted markers for diagnosis, prognosis, or disease activity.
Skin histopathology (for confirmation, if other diagnoses are in consideration): 4mm punch biopsy (skin and subcutaneous fat) from inflammatory or indurated border and sclerotic center (indicate on pathology requisition). Subtle changes in skin architecture may be detected by comparing lesional with site-matched unaffected skin biopsies.
Inflammatory: Interstitial and perivascular inflammatory cells (mainly lymphocytes and plasma cells with sparse eosinophils, mast cells or macrophages) are mainly located in the dermis but may also extend deeper into the subcutaneous tissue, depending on the depth of involvement; Tissue edema is usually evident. Thick collagen bundles may be present but may be absent in very early lesions (Figure 6).
Sclerotic: The initial inflammatory process leaves behind dense tissue, characterized by homogenization of papillary dermis with extensive sclerosis, collagen deposition and loss of appendageal structures. The inflammatory infiltrates are minimal (
Morphea (sclerosis and collagen deposition; 10X)
Antinuclear Antibodies (ANA) are positive in 39% to 80% (especially in linear and generalized subtype); ssDNA antibodies have been associated with linear morphea and may correlate with increased severity and increased activity (although not fully confirmed).
Imaging studies are only beneficial in selected cases:
Magnetic resonance imaging (MRI) to determine deeper (eg, fascial or muscle) involvement, which may underlie typical dermal lesions. Also useful for assessment of joints that may be directly affected by morphea or concomitant arthritis.
High frequency (14-20 MHz) ultrasonography (US) can be performed by an experienced radiologist for evaluation of skin thickness, atrophy of subcutaneous fat and muscle but also disease activity. Active inflammatory morphea may be visualized by increased echogenicity and hyperemia.
Always rule out:
- Cutaneous metastasis (breast, carcinoma en cuirasse) (
Cutaneous metastases should be ruled out in the differential diagnosis.
- Porphyria cutanea tarda
- Dermatofibrosarcoma protuberans
- Nephrogenic systemic fibrosis
Most likely differential diagnoses:
- Scleroderma (progressive systemic sclerosis).
- Lipodermatosclerosis (sclerosing panniculitis)
- Eosinophilic fasciitis: Shulman syndrome; likely related to morphea; transient eosinophilia may be present, symmetric involvement of (upper<lower) extremities with pain and edema; one third of cases are indistinguishable from morphea but may also occur without skin involvement
- Lichen sclerosus: Mainly affecting anogenital skin, however, may co-exist with morphea in extragenital locations (
Morphea and extragenital lichen sclerosus
- Connective tissue nevi
- Morpheaform basal cell carcinoma
- Chemically-mediated sclerosing skin conditions (toxic oil syndrome due to aniline-denaturated rapeseed oil, etc)
- Lyme disease (acrodermatitis atrophicans)
- Phenylketonuria (autosomal recessive, positive urinary ferric chloride test)
- Pretibial myxedema
- POEMS syndrome (Takatsuki or Crow-Fukase syndrome; acronym for sensorimotoric Polyneuropathy,Organomegaly, Endocrinopathy, Monoclonal gammopathy
- Cutaneous fat necrosis secondary to trauma/injections
Who is at Risk for Developing this Disease?
Women are affected two to five times more often than men. The disease is likely more common in Caucasians (population-based studies are lacking) with an overall incidence of 2.7 per 100,000 people. Children most commonly present with the linear subtype, whereas adults more often present with plaque or generalized subtypes. Every subtype can occur in any age group, however. Some postulate the presence of an “autoimmune phenotype.” Individuals with morphea tend to have a higher risk for other autoimmune diseases as well as increased prevalence of familial autoimmunity.
What is the Cause of the Disease?
Uncertain; likely a complex genetic disease resulting in immune dysregulation producing excessive dermal (or deeper) deposition of collagen and extracellular matrix. Development of lesions has been associated with local tissue trauma such as insect bites, intramuscular injections, radiation, surgery.
There is little understanding of underlying pathophysiology, especially on a molecular level. Most data are extrapolated from research on scleroderma patients. Autoimmune-mediated inflammation is likely the initial event in the formation of morphea lesions. Localized infiltration of immune cells and cytokine release then drives collagen deposition and extracellular matrix remodeling.
Systemic Implications and Complications
Morphea causes functional, psychologic, and neurologic complications. Morphea in children may cause growth retardation and muscular atrophy of affected limbs as well as limitation of range of motion and contracture, especially in deep lesions spanning joints or affecting the majority of the surface area of an extremity. Pain, sometimes severe, is reported in patients with deep involvement or circumferential involvement of an extremity.
Pruritus, numbness, and tingling are common complaints and may be a marker of disease activity. Low quality-of-life is a problem not only involving teenagers and children but also adults, especially those with large numbers of lesions or functional impairment. Lesions often appear on cosmetically sensitive sites and may produce permanent damage manifested by cutaneous or subcutaneous atrophy or pigmentary change.
Facial morphea linear lesions (eg, en coup de sabre lesions) may be associated with behavioral changes, learning disabilities and epilepsy. Headaches, uveitis and episcleritis are also sometimes present. In general every patient with morphea lesions on the face should undergo a baseline ophthalmologic evaluation and neurologic evaluation if symptoms are present.
Extracutaneous findings in 22% to 56% (
Arthritis underlying morphea lesion.
Physicians should also keep in mind that there is a greater risk for squamous cell carcinoma in patients with generalized/pansclerotic lesions due to chronic ulcerations.
Circumferential involvement of the upper chest and neck in some patients may cause dysphagia and dyspnea due to mechanical restriction. These findings should not be confused with esophageal and pulmonary involvement. Gastrointestinal and lung problems are typically seen in systemic sclerosis and softening of the skin may not be a relief for these patients. Circumferential limb lesions may also produce a compartment syndrome and trophic changes due to limited blood supply (eg. ulcerations).
Interestingly, a new study on adults with pediatric onset morphea revealed new insights into autoimmunne phenomena in these patients. Further, this study identified a subgroup of patients with a remitting/relapsing course over many years.

Optimal Therapeutic Approach for this Disease
There is no broad consensus on treatment approaches in morphea. In general, early inflammatory lesions respond best to any therapy and may even completely resolve. The more sclerotic or inactive the lesion the less likely therapy will be completely efficacious. Topical therapies are appropriate as monotherapy only in localized, nonprogressive morphea. Deep involvement, threatened or presence of functional limitation, and rapidly progressive disease are all indications for therapy aimed at shutting down the disease process and preventing extension of lesions (ie, phototherapy or systemic therapy).
Treatment decision is based on the following:
Patients with linear or generalized morphea often present with rapid progression and are at risk for functional impairment.
Depth of involvement: Phototherapy or systemic immunosuppressives are indicated depending on depth of involvement and potential for functional impairment.
- Superficial to mid-dermis: topical or phototherapy
- Deep involvement if widespread or presence/potential for functional/cosmetic impairment: systemic therapy
Stage and activity (inflammatory, sclerotic, atrophic)
- Early, active disease is most responsive to therapy (signs of activity: erythema, lesion extension, itching, tingling)
- Early intervention with aggressive systemic immunosuppressive (esp, MTX) is indicated to shut down active disease, especially if there is great risk of lesion expansion and progression or deep involvement (linear and generalized subtypes).
- Later stages of morphea with predominant sclerosis or so-called “burnt out lesions” may respond to intralesional steroid injection if solitary, or phototherapy if more widespread. Softening of the skin, reduction of contractures and sustaining range of motion are important goals and may also be achieved with physical or occupational physical therapy. Surgery and skin grafting may be considered in severe cases of stable non-progressing single lesions with debilitating functional or cosmetic impairment (en coup de sabre or Parry Romberg).
There are case reports documenting the reactivation and rapid extension of surgically excised lesions, so this should only be undertaken in patients with long-standing inactive disease and with a full discussion of the potential risk. The same is true regarding the use of filler substance for atrophic lesions.
Presence or potential for complications
Potential for extensive tissue damage (pigmentary change, atrophy, contractures, etc) and lesions with higher risk for secondary problems (facial lesions, en coup de sabre, etc) require more aggressive treatment (
Underlying liver disease or renal failure may be a contraindication for methotrexate and other systemic therapies. Collaboration with internists, pediatrics, or rheumatologists is crucial to providing best therapy for individuals with multiple illnesses.
Phototherapy (especially UVA1)
Currently, phototherapy is one of the best treatment options in morphea when it does not involve subcutis or below. The highest level of evidence is broad-band UVA (320 to 400nm wavelength), narrow-band UVB (wavelength centered around 311 nm), UVA1 (340 to 400nm wavelength). Due to a shorter wavelength, narrow-band UVB is useful in lesions affecting the superficial dermis, but of limited utility in deeper lesions due to lack of penetration.
UVA on the other hand has a greater depth of penetration and may even be effective in reducing inflammatory cytokine concentrations and endothelial cell dysfunction in skin lesions compared with UVB. UVA1 is divided into: low dose (20 to 40J/cm2), medium dose (40 to 80J/cm2) or high dose (80 to 120J/cm2).
UVA1 delivered 24 to 30 times in high or medium doses is superior to narrow band UVB or low dose UVA1, but efficacy in “burnt-out” lesions without the presence of inflammation and activity as well as in atrophic or deep subtypes is debatable. In these cases, or in patients with facial hemiatrophy (Parry Romberg) or eosinophilic fasciitis, systemic drugs are preferred.
Symptoms of skin tightening and inflammation should improve after 10 to 20 treatments as well as progression (start with a medium and increase to high dose; treatment is 3 to 5 days per week). Ideal dose and frequency of treatments have not been determined.
Side effects of UVA1 include transient headache, erythema, pruritus and hyperpigmentation of skin and morphea lesions in particular. Even smaller subtle lesions may become apparent after several treatment sessions due to development of hyperpigmentation. Concerns about carcinogenesis in patients receiving UVA1 phototherapy are legitimate, although an association has not been made to date. Advise patients to avoid extensive sun exposure and tanning beds and to be screened for cancerous lesions annually.
Methotrexate and systemic corticosteroids
Methotrexate (MTX) is one of the best systemic treatment options for morphea. Oral or intravenous (IV) glucocorticoids may be used along with methotrexate in rapidly progressive or inflammatory disease. Of note, optimum regimen for the use of methotrexate and/or glucocorticoids has not been established. Recommendations are based on current literature and the author’s experience.
Typical dose for children: 0.6mg/kg/week delivered orally or via subcutaneous injection.
Typical dose in adults: 15 to 25mg/week delivered orally or via subcutaneous injection
Until MTX takes effect, systemic corticosteroids may be used to rapidly shut down severely inflammatory, symptomatic, or progressive morphea (orally: 1mg/kg/d, or intravenous pulse: 30mg/kg/d for 3 days per month) for the first 3 months. Oral or parenteral (subcutaneous injection) forms of MTX are available. Frequent gastrointestinal upset may require switching to parenteral forms.
Pregnancy should be prevented during therapy and until 3 months after therapy because of the teratogenic effects of MTX. Widely available guidelines for appropriate monitoring of liver function, blood counts, and renal function should be observed. The most common side effects are nausea and gastrointestinal upset. For prolonged disease suppression patients often may have to stay on therapy for several years.
Topical steroids, although often prescribed, are of unclear benefit. Treating morphea at an early stage may require potent drugs or aggressive localized therapy to prevent spreading and progression, hence physicians should refrain from using topical steroids as a first-line therapeutic agent in cases of extensive, deep, or rapidly progressive morphea.
Intralesional triamcinolone (10mg/mL) once a month for 3 to 4 separate occasions may be beneficial in patients with solitary inflammatory sclerotic lesions and stable disease or as an adjunct to other therapy (triamcinolone acetonide 5 to 10mg/cc). This form of treatment is well tolerated, although not suitable for multiple lesions or large lesions.
Oral steroids (prednisone or methylprednisolone) are used during the initiation phase of MTX therapy, in combination with it, or in a solitary regimen in patients with contraindications to MTX and other systemic immunosuppressives (liver disease, kidney failure, anticipated pregnancy, low tolerance of MTX, etc). I recommend 1mg/kg initially, with a maximum of 60mg.
Vitamin D analogues
Vitamin D analogues are thought to influence keratinocyte differentiation, and promising studies justify their use in relatively superficial and no- progressive lesions (topical calcipotriene 0.005% ointment under occlusion two times per day).
Other treatment options with reported efficacy
- Mycophenolate mofetil
- Topical tacrolimus (0.1% twice a day) showed promising effects in small trials involving 13 patients. Especially erythematous lesions, which are thought to be inflammatory, were most responsive.
- Every patient should undergo occupational therapy and physical therapy (OT/PT) if contractures or limited range of motion are present.
- Cosmetic corrections and concomitant medical problems should be addressed in a multidisciplinary team of plastic surgeons, neurosurgeons, ear-nose-throat (ENT), rheumatologists, orthopedics and dermatologists.
There is one case report of a single patient with generalized morphea that is resistant to traditional therapy (including immunosuppression with cyclosporine), receiving imatinib. The off-label use of this tyrosine kinase inhibitor at a dose of 200mg per day for 6 months showed substantial improvement. After therapy cessation, no new lesions developed for 6 months.
Circumscribed: Close follow-up (linear and generalized morphea may present initially as circumscribed lesion). Additional evaluation is rarely needed
Head and face involvement: All patients: refer for ophthalmologic examination. Look for neurologic symptoms, jaw problems and dental malformation and displacement and refer as appropriate.
Extremity: Muscle pain or tightness, deep fixed lesion: MRI or US to determine subcutaneous, fascia, muscle or bone involvement.
Check CK and aldolase levels in peripheral blood. I usually check this if patients report any muscle pain, weakness, or tightness and clinically have deep bound down lesions in the area. I also consider MRI to image the area looking for muscle or fascial involvement, which might help localize a site to biopsy by general surgery if indicated.
A complete blood count (CBC) with differential is also helpful looking for eosinophilia in cases of eosinophilic fasciitis (EF). I usually take this as an indication for systemic immunosuppressive therapy and involve a pediatric or adult rheumatologist. Repeat imaging every 4 to 6 months to determine response to treatment.
Joint pain, stiffness, swelling or reduced weight bearing may indicate arthritis. (This may affect a joint underlying the morphea lesions or in an unaffected area.) Rheumatology consult may be indicated.
Decreased range of motion (ROM), contractures or limb length discrepancies would indicate the following:
- OT/PT not only for ROM, but also strengthening, proprioception, and balance
- Orthopedics consultation
- Rheumatology consultation
- Physical examinations with measurements of affected limbs every 6 months, looking for limb length descrepancy.
DETERMINE LEVEL OF DISEASE ACTIVITY USING THE FOLLOWING CRITERIA: New or increased lesion size over the past 3 months, presence of signs of disease activity (erythema, peripheral induration, pruritus, edema). Active lesions respond best to treatment. Inactive lesions (dermal/subcutaneous atrophy, pigmentary alteration, central sclerosis, residual functional impairment, no increase in lesion size or number over past 3 months) will not respond to medical therapy, but can benefit from supportive care and close monitoring for disease reactivation.
Each patient contact should be documented with simple digital photographs. These images, which are crucial in order to determine disease activity, progression and treatment success, should be reviewed during each visit
Phototherapy is safe and highly effective in many cases, although also time consuming and not readily available. Referring patients who live far away to temporary housing facilities and coordinating school and work schedules may be difficult.
Currently there is no curative therapeutic approach available, and there is general agreement among morphea experts that the systemic therapies suppress disease activity, as evidenced by reports of disease reactivation after cessation of therapy. Further, some patients experience a remitting/relapsing course. Thus management encompasses a complex interplay of risk vs benefit, minimizing side effects, and close patient follow-up. Patients also benefit from a multidisciplinary approach when severe disease is present.
At this time no laboratory tests are indicated to differentiate the various subtypes because there is no accepted biomarker for disease activity or severity. I order labs appropriate for a baseline evaluation if I am considering immunosuppressive therapy—CBC, complete metabolic panel (CMP), urinalysis (U/A,), purified protein derivitive (PPD) test for tuberculosis (TB). If the patient has other specific findings or symptoms that might indicate another connective tissue disorder or internal manifestations, I will order laboratory tests guided by those findings, ie, muscle pain tightness, creatinine phosphokinase (CPK), aldolase, MRI, CBC with differential looking for eosinophils.
Unusual Clinical Scenarios to Consider in Patient Management
Since the skin is usually the first organ affected by scleroderma, it is important to distinguish morphea from scleroderma, as they are different disorders with different prognoses. The predominant difficulty is in differentiating a generalized pansclerotic morphea patient who may present with dysphagia and dyspnea due to mechanical restriction from cutaneous sclerosis, not internal organ involvement. Further, these patients may present with edematous digits due to circumferential sclerosis of the forearms, but do not have true sclerodactyly/acrosclerosis.
Helpful clinical clues to differentiate pansclerotic morphea from scleroderma include that lesions spread from the trunk acrally, absence of Rayaud’s phenomenon, absence of nailfold capillary change, sparing of hands and digits, lack of characteristic antibodies associated with scleroderma, and absence of internal organ involvement.

From the Morphea Registry and DNA Repository at the University of Texas Southwestern Medical Center adults with pediatric onset morphea were identified. In contrast to other studies, 89% of our cohort had continued disease activity. Because of referral bias, prospective cohort studies are needed to determine accurate prevalence.

Phototherapy is advantageous in diseases of the epidermis and dermis, as it provides the most direct approach minimizing systemic side effects. Most recently, ultraviolet A1 (UVA1)phototherapy has emerged as a specific UVR phototherapeutic mechanism. It has shown to be therapeutic in a number of sclerosing skin conditions and other dermatitides, in many cases proving to be more effective than other phototherapy modalities. Treatment advantages of UVA1 phototherapy include the ability to penetrate into the deep layers of the skin to affect changes on disease-causing T cells, as well as activation of endothelial cells to promote neovascularization. UVA1t herapy also has been shown to be relatively free of side effects associated with other phototherapy regimens, including erythema and cellular transformation. These properties make UVA1 phototherapy an important treatment option for many debilitating skin conditions.)

In 16 (47%) patients therapy was discontinued when the disease was considered to be inactive clinically; however, seven (44%) of the 16 developed a relapse, necessitating repeat treatment.These data suggest that systemic corticosteroids and methotrexate in combination are beneficial and well tolerated in the treatment of children with LS. Because of the risk of relapse after discontinuing therapy, long-term monitoring is mandatory.)
