Subcutaneous sarcoidosis in a melanoma scar.

Cutaneous sarcoidosis often has been referred to. as the great imitator because skin lesions can present with various morphologies. Skin lesions may be the only site of involvement or may accompany systemic disease. Occasionally, sarcoidosis also may infiltrate scars from prior trauma, tattoos, or surgery. We report a case of subcutaneous sarcoidosis limited to a melanoma scar without any other cutaneous or systemic involvement. Familiarity with and proper diagnosis of cutaneous sarcoidosis can allow for appropriate systemic screening and timely management of the disease.
