ABSTRACT

Dermatofibroma is a common benign fibrohistiocytic tumor, usually observed in adults, with a slight predominance in females, usually located in lower limbs. The cause of dermatofibroma is still unknown, but it is widely accepted that dermatofibroma may result from a trauma, such as an insect bite, rupture of a follicle, or a follicular cyst. They present multiple variants; some of them are infrequent in clinical practice. The hemosiderotic dermatofibroma is a rare variant, with well-defined clinical and histological patterns but little reported in the literature or reported as synonymous with the aneurysmal dermatofibroma. We present two clinical cases of hemosiderotic dermatofibromas in female patients between 25 and 30 years old, with clinical evolution of 12 and eight months respectively; the report of an aneurysmal dermatofibroma in a 40-year-old female patient is also presented. The review of the literature is performed as uncommon variants of dermatofibromas.
