Background:

Peripheral primitive neuroectodermal tumors (PNETs) are rare malignancies, with PNETs of the female genital tract, particularly the vaginal and paravaginal regions, being exceptionally uncommon.
Early diagnosis and appropriate management are crucial for rare gynecologic tumors.

Observation:

A 36-year-old woman presented with symptoms mimicking a cervical fibroid.
Surgical intervention revealed a malignant round cell tumor, confirmed as CD99 positive via histopathology.

Findings:

The patient was diagnosed with a paravaginal PNET.
A multimodality treatment approach involving adjuvant chemotherapy (Ifosfamide, Etoposide, Vincristine, Doxorubicin, Cyclophosphamide) and radical radiotherapy was administered.

Keywords:

Implications:

Accurate histopathology and immunostaining are vital for diagnosing rare tumors like paravaginal PNET.
Successful management of this rare case underscores the efficacy of a combined treatment strategy.
This case contributes to understanding the clinical presentation and treatment of PNETs in the female genital tract.
