Abstract
- Atypical polypoid dermatofibroma(APDF) represents a distinctive clinicopathologic variant of dermatofibroma. We describe an unusual case of APDF occuring on the right buttoack in a 27-year-old female. The lesion was a reddish-hued, rounded, hard protuberant tumor with short pedicle, measuring 2,7 x 2.7 x 1.5cm. Excised tumor showed a well circumscribed dermal lesion localized in the protruded ar~ea, and dense proliferation of fibroblasts and capillaries reminiseent of fibrous or scle~rosing hemangioma type, with prominent focal cellular atypia. The tumor cells were vimentin-positive, but did not express CD34. There was no evidence of recurrence after 18 months postoperative follow-up.
