Generalized Morphea Coincident With Aplastic Anemia: A Case Report

Morphea is a rare skin condition characterized by erythematous or violaceous lesions as well as sclerotic plaques. Patients with morphea frequently have other autoimmune disorders. Contributing factors are thought to be autoimmunity and an increase in extracellular matrix production. A case of a 45-year-old male patient with progressive restriction of both shoulder movements and patchy discoloration over the abdomen, neck, back, forearms, and bilateral axillae is discussed in this article. Examination revealed multiple shiny hyperpigmented to hypopigmented indurated plaques, and some lesions showed erythematous to violaceous borders, fine scales, and woody induration. The neurological examination was normal. Skin biopsy showed a sparse superficial perivascular lymphohistiocytic infiltrate with thickening of collagen bundles that were hyalinized in the reticular dermis, which was consistent with superficial morphea. Hematological tests showed pancytopenia and bone marrow aspiration revealed hypocellular marrow, which was consistent with aplastic anemia. The patient was diagnosed with generalized morphea with aplastic anemia. The patient was referred to a transplant center for further treatment, but, unfortunately, he died of sepsis while waiting for his transplant. Our case may indicate a possible link between aplastic anemia and generalized morphea. Due to a possible similar underlying mechanism of pathogenesis, treatment of aplastic anemia may be effective in morphea also. Aplastic anemia must be detected early to reduce complications and mortality in patients.
