Cutaneous sarcoidosis. Report of two cases and literature review.

Sarcoidosis is a multi-system granulomatous disorder of unknown cause that presents more frequently in young adults with bilateral hilar adenopathy, pulmonary infiltrates, and skin or eye lesions. The multisystem clinical manifestations of this disease are a diagnostic challenge to all physicians. Although the clinical and pathological characteristics of sarcoidosis are well described, the decision to treat and the optimal therapy are less well defined. We report two patients of systemic sarcoidosis with cutaneous manifestations of the disease. Gallium whole body scintigraphy was performed and showed increased activity over the bilateral pulmonary hilar region (lambda sign), lacrimal and parotid glands (panda sign).
