Lipomas are benign tumours that consist of mature adipocytes. They are the commonest soft tissue tumours, most frequently seen in the trunk and proximal extremities. Lesions in the hand are uncommon, and giant lipomas of the hand, defined as greater than 5 cm in size, are particularly rare. We present a case of an exceptionally large giant lipoma of the hand, presenting as an extremely large inconvenient swelling of the palm in a 67-year-old woman. The diagnosis of lipoma was suggested via ultrasonography, and confirmed via MRI and histology. The lesion was successfully excised with no postoperative neurovascular deficit. The excised lesion measured 8×6×3 cm, one of the largest giant lipomas of the hand reported to date. When patients present with large lesions such as these a malignant cause must always be considered, and appropriate early imaging is essential when assessing these patients.
脂肪瘤是由成熟脂肪细胞构成的良性肿瘤。它们是最常见的软组织肿瘤，最常出现在躯干和四肢近端。手部病变并不常见，而手部巨大脂肪瘤（定义为大小超过5厘米）则尤为罕见。我们报告一例手部异常巨大的脂肪瘤病例，该病例表现为一名67岁女性手掌出现极其巨大且带来不便的肿胀。通过超声检查提示脂肪瘤诊断，并经磁共振成像（MRI）和组织学检查得以证实。该病变成功切除，术后无神经血管功能缺损。切除的病变大小为8×6×3厘米，是迄今为止报道的最大的手部巨大脂肪瘤之一。当患者出现如此大的病变时，必须始终考虑恶性病因，在评估这些患者时，早期进行适当的影像学检查至关重要。
