Summary
Primitive neuroectodermal tumour (PNET) is rare in adults. This case highlights an unusual peripheral PNET in a 61-year-old woman’s abdominal wall, emphasizing its potential for atypical presentations.
Area of Science:
- Oncology
- Pathology
- Surgical Case Reports
Background:
- Primitive neuroectodermal tumours (PNETs) are rare neoplasms, predominantly affecting children under ten.
- PNETs typically originate from the central or peripheral nervous system, with central origins being more common.
Purpose of the Study:
- To report an unusual case of a peripheral primitive neuroectodermal tumour (PNET) in an adult patient.
- To highlight the presentation and diagnosis of a PNET arising from subcutaneous tissue in the abdominal wall.
Main Methods:
- Case report of a 61-year-old female patient with a history of breast cancer.
- Clinical examination, surgical excision, and histopathological analysis of an abdominal wall lesion.
Main Results:
- A rapidly expanding abdominal wall lesion initially suspected to be benign.
- Histopathology confirmed the lesion as a localized primitive neuroectodermal tumour (PNET).
- The PNET was of peripheral origin, arising from subcutaneous tissue.
Conclusions:
- This case represents an atypical presentation of PNET in an adult.
- Peripheral PNETs can occur in subcutaneous tissues of the abdominal wall in adults, necessitating thorough histopathological evaluation.
