Dark Lesions in Dark-Skinned People - Dermatomyositis Diagnostic Challenge: First Report In The Gambia

Abstract

Dermatomyositis (DM) is an autoimmune condition characterized by progressive muscle weakness and distinctive skin rashes. Diagnosing DM in black patients can be challenging, as they often experience disease manifestations that differ, in their clinical expression, from traditional descriptions. Classic skin signs, such as erythema and Gottron papules, may not be as easily visible on darker skin. In contrast, chronic changes such as dyschromia and poikiloderma are more prominent. These more subtle manifestations can lead to delays in diagnosis and misdiagnosis. It is essential that the doctor be able to include dermatological manifestations as part of the systemic picture, in our case expressed by respiratory manifestations, arthritis, Raynaud's phenomenon and muscle weakness. Facilitating the diagnosis of classic forms. Knowledge of these distinctive features is crucial for physicians to ensure a timely and accurate diagnosis.
