Hibernoma: a benign lipomatous tumor mimicking liposarcoma.
Hibernoma is a rare, benign, slow-growing soft tissue tumor. It was named after its resemblance to the brown fat found in hibernating animals. Due to its rich vascularity and magnetic resonance appearance, this tumor may mimic a liposarcoma before tissue diagnosis. Complete resection with meticulous hemostasis is enough for treatment. Malignant potential has not been demonstrated. Herein we present a case of hibernoma arising from the left groin in a young man. The clinical presentation, radiographic and histopathologic features of this rare benign soft tissue tumor are presented. This tumor is clinically important because it is indistinguishable from malignant lesions.
