Case report
A 41-year-old female presented with a rapidly growing, painful 1 cm tumor on the right labium major. She underwent surgical excision in November 2017. The tumor was found to be encapsulated, but the capsule was ruptured during the procedure. A provisional diagnosis of leiomyoma was assigned.
She presented again in January 2018 with complaints of a painful mass in the same area. Examination revealed a dense, nodular tumor measuring 5x2 cm on the right labium majus deep to the prior surgical scar. Pelvic and abdominal ultrasound were routine. Due to clinical concern for malignancy based on rapid regrowth, the patient underwent wide local excision of the right vulva.
During excision, the mass was found to be a solid, well-encapsulated tumor measuring 5 x 2 cm with no evidence of any infiltrative process. Grossly negative margins were achieved. The incision was primarily closed.
