ABSTRACT
Fibroadenoma is a rare lesion of the vulva. It has been proposed that the origin of the tissue is either ectopic breast tissue or vulvar mammary-like glands (MLG). We report a case of vulvar fibroadenoma in a 33-year-old woman with a right vulvar mass presenting clinically as vulvar cyst. The cut surface of the tumor showed a white and homogenous appearance that was 2.5 cm in maximum dimension. Microscopically, the lesion was well-circumscribed but non-encapsulated. It revealed nodular, glandular and stromal proliferation, consistent with fibroadenoma of breast. Immunohistochemical staining for the estrogen receptor and progesteron receptor revealed nuclear positivity in the epithelium. Smooth muscle actin confirmed the presence of a myoepithelial cell layer. Staining for pancytokeratin showed epithelial cytoplasmic positivity.

The squamous cell carcinoma of ovary is very rare in the ovarian malignancy. The majority of squamous cell carcinomas of ovary are considered to be associated with mature cystic teratoma, Brenner tumor and malignant degenerated endometriosis. Therefore, pure ovarian squamous cell carcinoma is extremely rare. The pathogenesis, prognosis and proper treatment guideline of this malignancy are still unknown, because of it's rarity. Recently we experienced a case of primary squamous cell carcinoma without previously commented disease condition. After nearby cytoreductive surgery, postoperative chemotherapy with radiotherapy has been undergoing. We report this malignancy with a brief review of literature.
