Summary
A rare vulvar mass in a child was diagnosed as a peripheral primitive neuroectodermal tumor (PNET). This case is the second reported PNET of the vulva and the first in English literature.
Area of Science:
- Pediatric Oncology
- Gynecologic Pathology
Background:
- Peripheral primitive neuroectodermal tumors (PNETs) are rare, aggressive neoplasms.
- Vulvar PNETs are exceptionally uncommon, with limited documented cases.
Observation:
- A 10-year-old Hispanic female presented with a persistent vulvar mass over three months.
- Clinical examination revealed a significant vulvar lesion requiring further investigation.
Findings:
- Histopathologic examination confirmed the diagnosis of a peripheral primitive neuroectodermal tumor (PNET).
- The tumor exhibited characteristic PNET morphology on microscopic analysis.
Implications:
- This report details the second known case of vulvar peripheral PNET globally.
- It represents the first documented instance of this rare vulvar tumor in the English-language medical literature.
- Highlights the importance of considering rare diagnoses in pediatric vulvar masses.
