Abstract
Hibernoma is a rare benign lipomatous tumor derived from brown fat, which is typically found in infants. Specifically, intrascrotal hibernoma is extremely rare with only one case reported to date. We encountered the second case, which was successfully treated with surgical resection without any recurrence at 3 years.
The patient was first misdiagnosed with an intrascrotal liposarcoma preoperatively. Preoperative usefulness of imaging modalities to discriminate hibernomas and liposarcomas is limited due to lack of specific features of hibernomas with its rarity. Here, we report a case of intrascrotal hibernoma in addition to a current literature review.
Hibernoma is a rare benign lipomatous tumor.
Specifically, intrascrotal hibernoma is extremely rare with only one case reported to date.
Preoperative discrimination of hibernomas and lipomatous tumors is difficult.
A histopathological examination is needed to make a definitive diagnosis of hibernomas.
Immunohistochemical and FISH analyses should be performed, in cases of intrascrotal hibernoma.
