Lipomas are tumors composed of mature adipocytes, originating from the mesoderm, and are the most common soft tissue tumor. According to the World Health Organization classification of human soft tissue and bone tumors, there are 14 types of benign tumors, including mature adipose tissue. Osteolipoma is known as the rarest subtype of lipoma.
A 63-year-old female presented to our hospital for the evaluation and treatment of a palpable mass with pain in the right knee.
The diagnosis was confirmed as lipoma with osteocartilaginous metaplasia.
Surgical removal of the tumor was performed.
The main symptoms improved immediately after the surgery and recovered without any complications or recurrence until 2 years after surgery.
Lipoma with osteochondral degeneration is a rare variant of lipoma and it is important to differentiate it from other malignant tumors. Pathological confirmation should be performed after marginal resection of the mass.
脂肪瘤是由成熟脂肪细胞组成的肿瘤，起源于中胚层，是最常见的软组织肿瘤。根据世界卫生组织（WHO）人类软组织和骨肿瘤分类，良性肿瘤有 14 种类型，包括成熟脂肪组织。骨化性脂肪瘤是脂肪瘤中最罕见的亚型。
一名 63 岁女性因右膝疼痛和可触及的肿块到我院就诊。
诊断为伴有骨软骨化生的脂肪瘤。
手术切除肿瘤。
术后主要症状立即改善，无任何并发症，随访 2 年无复发。
伴有软骨骨化的脂肪瘤是脂肪瘤的一种罕见变异，需要与其他恶性肿瘤相鉴别。应在肿瘤边缘切除后进行病理证实。
