Summary
This report details the second known case of intrascrotal hibernoma, a rare brown fat tumor. The patient was successfully treated with surgery, highlighting the challenges in diagnosing this rare condition.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Hibernoma is a rare, benign lipomatous tumor originating from brown adipose tissue.
- Intrascrotal hibernomas are exceptionally rare, with only one prior reported case.
- Distinguishing hibernomas from liposarcomas preoperatively is challenging due to overlapping imaging features.
Observation:
- A second case of intrascrotal hibernoma is presented.
- The patient was initially misdiagnosed with intrascrotal liposarcoma.
- The tumor was successfully treated with surgical resection.
Findings:
- The patient experienced no recurrence of the intrascrotal hibernoma at a 3-year follow-up.
- Imaging modalities showed limited utility in differentiating intrascrotal hibernoma from liposarcoma.
- This case contributes to the limited literature on intrascrotal hibernomas.
Implications:
- Highlights the rarity and diagnostic challenges of intrascrotal hibernoma.
- Emphasizes the importance of surgical resection for successful treatment.
- Suggests a need for further research into diagnostic markers for rare lipomatous tumors.
