Dermatofibrosarcoma protuberans of the vulva

Abstract

Dermatofibrosarcoma protuberans of the vulva is an uncommon low-grade sarcoma of dermal origin. Although wide local excision is the treatment of choice, microscopic tumor projections beyond the central tumor nodule explain the tumors' propensity for local recurrence. Frozen sections of margins may be useful to ensure complete resection. The following report contributes two additional patients with this uncommon neoplasm. Notably, one of these two had a fibrosarcomatous area within the dermatofibrosarcoma protuberans. This is the second reported case of a fibrosarcoma arising in a dermatofibrosarcoma protuberans of the vulva.
