Morphea is an inflammatory, sclerosing skin condition of unknown cause that generally does not present systemic manifestations. A 66-year-old Caucasian Peruvian female patient, who was previously a nurse, presented with a prior history of 4 years of indurated dermal plaque lesions with constant progression. Diagnosis of morphea was made by clinical examination and skin biopsy. The patient started topical treatment with methoxsalen and phototherapy. When no improvement was seen, it was switched to methotrexate. However, due to changes in liver profile, phototherapy was restarted with progressive clinical improvement. It is essential to differentiate all morphea subtypes for proper management.

While mucocutaneous manifestations of COVID-19 have been frequently reported and added to our knowledge every day during the pandemic, another issue is the COVID-related diseases that can present as intensified lesions of underlying diseases, a new disease, or changes in the behavior of an old lesion. Given that immune system overreaction and cytokine storm are among the most prominent events in COVID-19, the incidence of autoimmune diseases is expected to increase after COVID-19, as confirmed in several reports. To increase the body of knowledge about short- and long-term outcomes of COVID-19 for specialists, it is essential that similar cases be reported and collected for years to come. The present study investigated a case of pansclerotic morphea that rapidly progressed a few weeks after infection with COVID-19 in a 57-year-old woman with no history of any autoimmune skin or rheumatic diseases. She was prescribed outpatient COVID-19 treatment of azithromycin, vitamins D and C, and then quarantined for 2 weeks. The manifestations of the disease were exacerbated at each follow-up and sampling visit at short intervals. This kind of pansclerotic morphea is reported for the first time.

Physicians should be vigilant for COVID‐19 vaccine side effects and investigate any associated cutaneous manifestations. This will ultimately facilitate better understanding and recognition of various skin reactions related to the vaccine.

Generalized morphea is a disease characterized by wide-spread sclerosis of the skin. A 39-year-old man presented with history of multiple pigmented and bound-down plaques on the body along with mucosal involvement. Dermatological examination showed multiple indurated and sclerosed plaques with follicular plugging in few of them and gross thickened eroded and glazed tongue. The constellation of these findings with histopathological correlation led us to diagnosis of this spectrum of cutaneous involvement. The coexistence of localized morphea with lichen sclerosis et atrophicus has been reported earlier but existence of these entities with submucosal fibrosis in a same patient is documented here and is the first of its kind.

Generalised morphea (GM) is a subtype of localised scleroderma that usually manifests with bilateral involvement. Unilateral generalised morphea (UGM) is a rare variant of GM. This is a case report of a Taiwanese girl with UGM over the left side of her body. She presented with hyperpigmentation, tightness, and skin atrophy over the left extremities and trunk. Mild range of motion (ROM) limitation over the left knee was also noted. At the clinic, the patient was given oral prednisolone, oral methotrexate (MTX), and oral D-penicillamine. topical emollient and topical glucocorticoids were also given. The dose of oral prednisolone was tapered gradually. All symptoms were improved under the treatment and regular rehabilitation program. To date, there is very little evidence to form the basis for treatment recommendations. This case report provides a treatment option for UGM in the paediatric group without the use of intravenous methylprednisolone pulse therapy.

Morphea is an inflammatory skin disorder characterized by excessive collagen deposition. Although treatment algorithms for morphea subtypes have been suggested, no consistent recommendations are available. This study attempts to evaluate the clinical efficacy of methotrexate (MTX) as monotherapy in refractory generalized morphea. It is a retrospective study, including 20 patients who had already been treated with various topical and systemic therapies with minimal clinical improvement. Patients received orally MTX at a of dosage 15 mg once weekly. Duration of the use, dosage of MTX, and adverse events were recorded. Clinical assessment of skin lesions was performed and documented. The mean disease duration was 27 months before the initiation of MTX treatment. After 12 months of therapy, very good response was achieved in 6 patients (30%), good response in 10 patients (50%), and fair response in 2 patients (10%), while 2 patients (10%) had failed treatment. Patients were followed up for a mean time interval of 21 months. No serious adverse event was recorded. MTX has been already proved to be an effective and well-tolerated treatment in pediatric patients with morphea. The majority of the group of adult patients showed very good and good improvement when treated with MTX. Although this is an uncontrolled study, MTX monotherapy was considered a safe and effective treatment for the management of this specific clinical subset of morphea in adults.

We report the case of a 45-year-old female with generalized morphea (GM), who exhibited positivity for the anti-centromere antibody (Ab). She frequently developed multiple sclerotic skin lesions, whose histological findings were compatible with morphea. She demonstrated favorable responses to topical and oral steroids. Cases of GM associated with systemic sclerosis (SSc)-specific Abs (anti-Scl-70 Ab, anti-centromere Ab, and anti-RNA polymerase III Ab) have rarely been reported. The previously reported GM cases involving anti-SSc-specific Abs exhibited some skin manifestations of SSc, such as nailfold capillary changes. However, our case did not show any signs of SSc or limited cutaneous SSc. More cases are needed to clarify whether GM with SSc-specific Abs leads to SSc.
