Abstract
INTRODUCTION: Atrophic dermatofibroma is a rare variant of dermatofibroma which is many times underdiagnosed. CASE REPORT: We report a case report of a 29-year-old female who came to the dermatology department with black-colored lesions on the lower leg for the past 7 years. Histopathological examination revealed a non-encapsulated dermal tumor involving upper to deep reticular dermis and extending to superficial subcutis. There was epidermal hyperplasia, and at the center of the lesion a slight epidermal atrophy was present. DISCUSSION: It is a commonly underdiagnosed variant of dermatofibroma. Histopathologically, this disorder presents as a decrease in at least 50% of the thickness of the dermis relative to the adjacent dermis. The case is rare and hence reported.
