## Abstract

Hibernoma is a rare benign soft-tissue tumor derived from vestigial brown adipose tissue. Mammary hibernoma is a rare entity that is usually misdiagnosed clinically and radiologically as lipoma or liposarcoma.

We report a rare entity by dscribing the clinical, radiological and pathological features in a patient as well as the differential diagnoses and treatment. The patient underwent complete resection of the tumor and remained disease-free during 2 year follow up with no sign of any recurrence.

Hibernomais a rare benign tumor. We focus on discussing its differences from other benign or malignant tumors.

The clinical significance of this report is to distinguish this rare tumor from other soft tissue neoplasms, both benign and malignant.
