Abstract
PURPOSE
Hibernoma is a very rare benign soft tissue tumor of the hypervascularized brown fat tissue with no malignant potential. MATERIALS AND METHODS: However, it is difficult to differentiate a hibernoma from other malignant tumors, such as liposarcoma using computed tomography and magnetic resonance imaging, and a surgical resection with histological confirmation is the treatment of choice.
RESULTS
Histopathologically, hibernoma is composed of brown adipose cells that are polygonal and multivacuolated with a centrally located nucleus and granular cytoplasm, unlike white adipose cells.
CONCLUSION
This article describes a patient with a histologically-confirmed hibernoma of the right shoulder.
Key Words: Hibernoma; Fatty tumor; Brown fat; Lipoma
