Case report of vulvar schwannoma and literature review
Schwannoma is a rare benign encapsulated tumor derived from neural sheath cells. The tumor is more common in the head and neck regions and the extremities. Its location in the vulvovaginal region is a rare phenomenon with a few reported cases worldwide. We report a case of a large vulvar schwannoma occurring in an 18‑year‑old woman, primigravidae at 35 weeks gestation. The ulcerated tumor mass which measured 10.5 × 7 × 6.5 cm and weighed 249.2 grams was located on the right labium majus with extension into the vagina. The tumor evoked strong immunohistochemical reactivity to S‑100. There was no evidence of recurrence after several weeks of excision of the neoplasm.
Key words: Pelvic nerve sheath tumor; schwannoma; vulva mass.
