Lipomas are benign tumors of mature adipose tissue which can occur in subcutaneous, intramuscular, intermuscular, parosteal, and intraosseous compartments. Parosteal lipoma is a rare type of lipoma, accounting for less than 0.1% of primary bone neoplasms and 0.3% of all lipomas. Parosteal lipomas commonly arise in the femur and extremities. Around 150 cases have been reported in English literature with scapula being a rare site of involvement. They are known to be associated with underlying bony changes like focal cortical hyperostosis, pressure erosion of the underlying bone, and bowing deformity or with underlying osteochondroma. We report a rare case of a parosteal lipoma arising in the scapula with a bony excrescence in a 38-year-old male.
脂肪瘤是成熟脂肪组织的良性肿瘤，可发生于皮下、肌肉内、肌间、骨膜旁和骨内间隙。骨膜旁脂肪瘤是一种罕见的脂肪瘤类型，占原发性骨肿瘤的比例不到0.1%，占所有脂肪瘤的0.3%。骨膜旁脂肪瘤通常发生于股骨和四肢。英文文献报道了约150例病例，肩胛骨是罕见的受累部位。已知它们与潜在的骨质改变有关，如局灶性皮质增生、下方骨质的压力性侵蚀、弓形畸形或与潜在的骨软骨瘤有关。我们报告了一例罕见的发生于肩胛骨且伴有骨质增生的骨膜旁脂肪瘤病例，患者为一名38岁男性。
