Adipose tumors are dominated by lipomas, but other rarer entities may be encountered such as hibernoma which is a benign tumor that develops from brown fat. The thigh is the preferred location for hibernomas, but the tumor can appear in other areas. The upper limb is a rare localization and there is only 1 case of hibernoma on the hand already reported in the English literature. We report the case of a hibernoma of the palmar aspect of the hand. The tumor had no clinical specificities. MRI showed an uncertain appearance mimicking liposarcoma. The diagnosis was only confirmed by histological study. The treatment consisted of complete excision of the tumor. At a follow-up of 8 months, there was no recurrence.
脂肪肿瘤以脂肪瘤为主，但也可能遇到其他较罕见的类型，如源自棕色脂肪的良性肿瘤冬眠瘤。大腿是冬眠瘤的首选发病部位，但该肿瘤也可出现在其他区域。上肢是罕见的发病部位，英文文献中仅报道过1例手部冬眠瘤。我们报告1例手掌部冬眠瘤病例。该肿瘤无临床特异性表现。磁共振成像（MRI）显示外观不明确，类似脂肪肉瘤。仅通过组织学检查确诊。治疗方法为肿瘤完整切除。随访8个月，无复发。
