Dermatofibromahttps://en.wikipedia.org/wiki/Dermatofibroma
Dermatofibroma is hard solitary slow-growing papules (rounded bumps) that usually brownish to tan; Although typical dermatofibromas cause little or no discomfort, itching and tenderness can occur. Dermatofibromas can be found anywhere on the body, but most often they are found on the legs and arms.

Dermatofibromas may be formed as a reaction to previous injuries such as insect bites or thorn pricks. Dermatofibromas are classed as benign skin lesions, meaning they are completely harmless, though Dermatofibromas may be confused with a variety of subcutaneous tumours. Deep penetrating dermatofibromas may be difficult to distinguish, even histologically, from rare malignant fibrohistocytic tumours like "dermatofibrosarcoma protuberans".

Most are benign, but large lesions (>5 mm) may require biopsy.
