| Abstract: | A 56-year-old woman was referred to our hospital with a pathological diagnosis of squamous cell carcinoma of the cervix. We performed a re-biopsy of the vaginal mass and cervical conization. The mass was originally reported as an epithelioid MPNST after re-biopsy. Strong diffuse S-100 positivity, epithelioid morphology of the lesion, and negativity to all other immune histochemical markers confirmed the diagnosis of epithelioid MPNST. Cervical conization specimen was negative for any neoplasms. |
