Clinical Features and Treatment of Dermatofibrosarcoma Protuberans Affecting the Vulva: A Literature Review.

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a low-to-intermediate grade cutaneous neoplasm with a low propensity for metastasis and a high rate of local recurrence. It typically presents as a dermal plaque or nodule on the trunk, limbs, or head and neck region. Vulvar DFSP has also been described, although it is less common.

OBJECTIVE: To review the available literature and discuss the clinical course of DFSP affecting the vulva.

MATERIALS AND METHODS: We reviewed the existing English-language literature on DFSP of the vulva with respect to clinical presentation, diagnosis, treatment, and outcome.

RESULTS: Thirty three case reports and series were included (n = 54 patients). Vulvar DFSP most commonly presents as a slowly enlarging tender or asymptomatic mass on the labia majora, with histological findings of classic DFSP. Most patients were treated with wide local excision. Three patients were treated with Mohs micrographic surgery, which may decrease local recurrence and seems well suited for use in vulvar DFSP.

CONCLUSION: This literature review comprehensively reviews and describes the clinical presentation of vulvar DFSP and the treatment options for this rare vulvar neoplasm.
