Clinical Characteristics of Basal Cell Carcinomas of the Vulva: An Institutional Retrospective Review

BACKGROUNDThere are limited data on the etiology, clinical characteristics, and optimal treatment of vulvar basal cell carcinoma (BCC).OBJECTIVEThis retrospective review may aid in treatment decisions for vulvar BCC.MATERIALS AND METHODSA retrospective review of our institutional CoPath database was performed, using search terms to identify cases of vulvar BCCs from 2000 to 2018.RESULTSA total of 35 cases of vulvar BCC were included. Patient age ranged from 33 to 97 years with a mean age of 70 years. Of the 35 cases, 28 (80%) involved the cutaneous vulva, 6 (17%) involved the suprapubic area, and 1 (3%) involved the clitoris. Most vulvar BCCs were treated by wide local excision (46%) and vulvectomies (37%), with 3 cases treated with Mohs (11%) and 2 with electrodesiccation and curettage (6%). Preoperative tumor sizes were 0.86 cm²for Mohs, 0.94 cm²for excision, and 1.54 cm²for vulvectomy. The mean margins were 3 mm for Mohs, 4.4 mm for wide local excision, and 6 mm for vulvectomy. Most cases (77%) were identified and treated by gynecology.CONCLUSIONMohs micrographic surgery should be considered for the advantages of being tissue sparing, evaluating the complete peripheral and deep margin, and avoiding the costs and risks of general anesthesia.
