Abstract

Dermatofibroma (DF) is one of the most common benign soft tissue tumors. Various histological variants of DF have been described, and it is important to discern the different variants to evaluate the prognosis. A 43-year-old female patient with no specific medical history presented with multiple brown-colored nodules on the right arm for 5 years. Biopsy specimens showed a predominance of collagen and fibroblasts in a whorled arrangement with moderate cellularity, findings that were consistent with fibrocollagenous DF. The patient underwent excision of the largest lesion and revisited our department 3 months after surgery with local recurrence at the excision site. We report a rare case of multiple fibrocollagenous DF with local recurrence at the excision site.
