Lipomas are the most common benign mesenchymal tumors, making up 50 % of soft tissue tumors. However, while they frequently occur in areas like the head, neck, shoulders, and back, lipomas in the hands and wrists are rare, particularly in the fingers where they are exceptionally uncommon.
We present a case of 62-year-old female presented with a six-year history of a gradually enlarging, painful swelling on the palmar aspect at the base of her left index finger. Examination revealed a soft, fluctuating, 3 cm × 2 cm swelling. USG and MRI suspected it to be a lipoma. The lesion was excised, and histopathology confirmed a benign lipoma.
Lipomas, derived from mesenchymal preadipocytes, often have genetic and metabolic links, including in individuals with obesity, hyperlipidemia, and diabetes. While typically asymptomatic, lipomas in the hands and fingers can cause pain and impairment, necessitating surgical resection. Accurate diagnosis may require imaging, and treatment yields favourable outcomes with low recurrence rates.
Despite their rarity, lipomas in the hands and fingers should be considered when evaluating non-discharging swellings. Surgical resection is the primary treatment.
脂肪瘤是最常见的良性间叶组织肿瘤，占软组织肿瘤的50%。然而，虽然脂肪瘤常发生于头部、颈部、肩部和背部等部位，但手部和腕部的脂肪瘤较为罕见，尤其是在手指部位更是极为少见。
我们报告一例62岁女性患者，其左手食指根部掌侧有一个逐渐增大、疼痛性肿胀，病史长达6年。检查发现一个柔软、有波动感、大小为3 cm×2 cm的肿胀。超声检查（USG）和磁共振成像（MRI）怀疑为脂肪瘤。该病变被切除，组织病理学证实为良性脂肪瘤。
脂肪瘤起源于间叶前脂肪细胞，通常与遗传和代谢有关，肥胖、高脂血症和糖尿病患者中更为常见。虽然脂肪瘤通常无症状，但手部和手指的脂肪瘤可引起疼痛和功能障碍，需要手术切除。准确诊断可能需要影像学检查，手术治疗效果良好，复发率低。
尽管手部和手指的脂肪瘤罕见，但在评估无分泌物的肿胀时应考虑到这种情况。手术切除是主要治疗方法。
