Scar Sarcoidosis with Pulmonary involvement in a 44 year old African woman: Case Report and Review of Literature

Abstract

Sarcoidosis is a rare multisystem granulomatous disease of unknown aetiology that affects virtually all organ systems, including the lungs, lymph nodes, liver, skin etc. Skin involvement is seen in about 20-35% of the patients with systemic sarcoidosis. Scar sarcoidosis is the most clinically characteristic and a rare cutaneous manifestation of sarcoidosis. It may predict systemic disease, especially pulmonary involvement. We present a case of scar sarcoidosis in a 44-year-old African woman that developed disseminated infiltrated papules, nodules and plaques on old scars from traditional marks on the face and anterior abdominal wall, and also had pulmonary involvement. Histological examination of the biopsy specimen of the scar lesions confirmed sarcoidosis. She was treated with systemic corticosteroid which showed significant clinical improvement. Scar sarcoidosis should be considered in the differential diagnosis of changes in all scar tissue and also to adequately evaluate such patients for pulmonary involvement.
