Hibernoma is an uncommon benign lipomatous tumor that originates from residual brown fat. It commonly affects adult patients aged between 30 and 40 with a slight predominance in male more than female and usually seen in the thigh, shoulder, back, chest, axilla, and neck. The present report aimed to highlight on a viable differential diagnosis of thigh mass including liposarcoma and atypical lipoma.Case Presentation: This is the case report with detailed history, examination of 39-year-old male patient with hibernoma over medial aspect of thigh. Marginal surgical resection was carried and sent to histopathology to confirm the diagnosis of hibernoma.Conclusion: Hibernoma is a rare benign lipomatous soft tissue tumor with no known risk for malignant transformation or metastasis. Based on imaging examination, it can mimic malignant tumors such as, liposarcoma, in which we believe that biopsy is required in order to reach the diagnosis in most of the cases.Keywords: Soft tissue tumor, hibernoma, brown fat, liposarcoma.
