%X UNASSIGNED: Hibernoma is a rare benign adipose tumor that arises from brown fat. Often misdiagnosed as liposarcoma, hibernomas require biopsy and histopathological examination for accurate diagnosis. This case report presents an unusual instance of hibernoma located in the posterior thigh of an elderly patient, emphasizing the diagnostic challenges and surgical management involved.
METHODS: We report the case of Mrs. F.D., a 70-year-old woman with a history of ovarian cyst surgery 17 years prior, who presented with a mass in the posterior left thigh. The mass had been developing over two years and was hard, painless, and measured 7 × 12 cm. Initial imaging suggested liposarcoma; however, an MRI revealed a 9 × 19 cm mass with heterogeneous tissue characteristics. A surgical biopsy confirmed the diagnosis of hibernoma. The tumor was excised completely, and histological examination showed typical features of hibernoma.
UNASSIGNED: Hibernomas, although rare, should be considered in the differential diagnosis of soft tissue masses. Imaging techniques such as MRI are essential, but definitive diagnosis relies on histopathology. Surgical excision is the treatment of choice, requiring meticulous technique to manage the hypervascular nature of the tumor.
CONCLUSIONS: This case underscores the importance of considering hibernoma in differential diagnoses and highlights the role of biopsy for accurate diagnosis. Complete surgical excision is crucial to prevent recurrence. Further research is needed to better understand the pathogenesis and optimal management of hibernomas.
