Xanthoma is a rare pseudotumor of connective tissue, consisting of histiocytes with lipid deposits. Usually, it manifests as encapsulated lobular yellowish mass, often associated with familial hypercholesterolemia (FH). We present a case of xanthoma of tendoachilles just proximal to its insertion site, secondary to FH. The patient was a 28-year-old female presenting with a 2-year history of difficulty ambulating and complaints of swelling over the posterior aspect of her left lower leg just proximal to her heel. She had a deranged lipid profile level and was started on a lipid lowering agent for 3 weeks followed by total excision of the lesion with flexor hallucis longus tendon graft augmentation. The patient was able to bear full weight at 6 weeks and could stand on her toes by 4 months. No recurrences were noted at 1 year follow-up.

跟腱黄瘤：管理和随访

黄瘤是一种罕见的结缔组织假瘤，由具有脂质沉积物的组织细胞组成。通常表现为有包膜的小叶黄色肿块，常与家族性高胆固醇血症 (FH) 相关。我们介绍了一例紧邻其插入部位的腱鞘黄色瘤，继发于 FH。患者为 28 岁女性，有 2 年行走困难病史，主诉左小腿后侧靠近脚跟处肿胀。她的血脂水平紊乱，开始服用降脂药 3 周，然后用拇长屈肌腱移植物增强术完全切除病变。患者在 6 周时能够承受全部重量，4 个月时可以用脚趾站立。随访1年未见复发。
