Abstract
|
|
|
Atypical polypoid dermatofibroma (APDF) represents a distinctive clinicopathologic variant of dermatofibroma. We describe an unusual case of APDF occuring on the right buttock in a 27-year-old female. The lesion was a reddish-hued, rounded, hard
protuberant tumor with short pedicle, measuring 2.7×2.7×1.5cm. Edcised tumor showed a well-circumscribed dermal lesion localized in the protruded area, and dense proliferation of fibroblasts and capillaries reminiscent of fibrous or sclerosing
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's postoperative follow-up. (Kor J Dermatol 1996;(5) : 818~822)
