Vulvar Dermatofibrosarcoma Protuberans: Surgical Planning and Management Considerations for the Dermatologic Surgeon

Dermatofibrosarcoma protuberans (DFSP) arising in the vulvar and perivulvar region poses unique challenges to the dermatologic surgeon. The potential for broad subclinical extension and involvement of deeper and high-risk functional structures requires a strong knowledge of relevant anatomy. Careful considerations are required for preoperative arrangements, surgical day preparations, and postoperative surveillance to improve treatment outcomes and patient experiences.

The authors aim to provide a practical guide for the dermatologic surgeon, which outlines surgical planning and management recommendations for vulvar DFSP. Emphasis on pelvic anatomy through cadaveric and patient images as well as anatomical illustrations will be included.

A literature review was performed to identify evidence-based management recommendations for vulvar DFSP. Authors share anecdotal perioperative recommendations for optimizing the patient experience. A detailed pelvic dissection of a female cadaver was performed for anatomical depiction of relevant high-risk structures. Illustrations of sensory nerve distributions were created for reference.

Vulvar DFSP is a challenging cutaneous tumor in a sensitive anatomical location. As Mohs surgery offers clear advantages over wide local excision, the authors provide dermatologic surgeons with detailed anatomy review resources as well as recommendations and considerations for management and perioperative planning for this specialized site.
