title: Hibernoma of the axillary region: a rare benign adipocytic tumor.
abstract: Hibernoma is a rare benign tumor considered to arise from remnants of fetal brown adipose tissue. It tends to occur in sites where brown fat persists beyond fetal life, such as the interscapular region, but can occur in sites where brown fat is usually absent in adults. Clinicallywell, hibernomas are slow-growing, asymptomatic tumors. However, unlike lipomas, MRI findings sometimes mislead clinicians to diagnose a malignant neoplasm. We describe a 63-year-old male with an axillary hibernoma involving the brachial neurovascular bundles and mimicking a well-differentiated liposarcoma, from which it should be distinguished.
