Sarcoidosis and dermatomyositis in a patient with hemoglobin SC. A case report and literature review.
Although sarcoidosis has occasionally been associated with hemoglobinopathies, its association with dermatomyositis is extremely rare. A 24 y/o African American male with hemoglobin SC disease developed proximal weakness. He had heliotrope rash, muscle weakness, elevated serum CK, myositis by EMG, and no malignancy. A muscle biopsy confirmed dermatomyositis. Two years later, he was hospitalized with constitutional and respiratory symptoms and parotid enlargement. Chest X-ray and CT scan showed diffuse micronodular infiltration in both lungs and mediastinal lymphadenopathy. A transbronchial lung biopsy revealed non-caseating granulomata consistent with sarcoidosis. AFB and fungal stains and cultures were negative. Thus, in this case, sarcoidosis developed after or in association with dermatomyositis. A review of world's literature showed five other non-identical cases of dermatomyositis associated with sarcoidosis.
