Case of cutaneous sarcoidosis with multiple morphologies and review of the clinical spectrum

Abstract

1. Abstract Sarcoidosis is a multi-organ disease that commonly presents with cutaneous manifestations. However, it can clinically mimic innumerable skin conditions, posing a diagnostic challenge for the clinician. Here, we describe a case of a 51-year-old female with cutaneous sarcoidosis exhibiting multiple morphologic patterns. Physical exam showed erythematous to violaceous indurated, large plaques and deep firm nodules on the upper and lower extremities. Two months later, she developed a diffuse papular eruption on extremities and involving a prior scar. Biopsies showed granulomatous dermatitis consistent with sarcoidosis. Imaging revealed pulmonary involvement. This case highlights some of the cutaneous manifestations of sarcoidosis. We propose that in the presence of multiple co-existing morphologies, a single process such as sarcoidosis should be strongly considered.
