Retroperitoneal primitive neuroectodermal tumors (PNET) are rare, aggressive cancers. This case highlights a PNET diagnosis in an 81-year-old woman presenting with flank pain and hematuria, confirmed by CT scan and pathology.
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- Retroperitoneal primitive neuroectodermal tumors (PNET) are rare, highly malignant neoplasms.
- PNET typically affects young adults and is known for early metastasis.
Observation:
- An 81-year-old woman presented with right flank pain and hematuria.
- A contrast-enhanced CT scan revealed a large, heterogeneous right kidney mass measuring approximately 12 cm.
Findings:
- The clinical presentation, imaging findings, and pathological results confirmed a diagnosis of primitive neuroectodermal tumor (PNET).
- Molecular analysis further supported the PNET diagnosis.
Implications:
- This case expands the known age range for retroperitoneal PNET presentation.
- Highlights the importance of considering rare diagnoses in older patients with atypical presentations.
- Emphasizes the role of multimodal diagnostic approaches in confirming PNET.
