Vaginal epithelioid malignant peripheral nerve sheath tumor nearly misdiagnosed as advanced cervical cancer: A case report

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. (C) 2020 Published by Elsevier Ltd on behalf of IJS Publishing Group Ltd.
