Lipomas are common benign soft tissue tumors composed of mature adipocytes, typically presenting as slow-growing, painless subcutaneous nodules. While the underlying etiology remains unclear, various factors have been proposed as potential contributors. In some individuals, multiple subcutaneous lipomas can develop, and their occurrence has been considered in relation to systemic conditions or familial predisposition. Hormone replacement therapy (HRT), commonly used for menopausal symptom management, influences lipid metabolism and angiogenesis through hormonal signaling pathways; however, its potential role in lipoma formation remains uncertain. Herein, we present a case of a 57-year-old woman who developed multiple subcutaneous lipomas on the thighs and buttocks after initiating HRT. This case highlights a possible association between hormonal changes and lipoma formation, emphasizing the importance of further research into the mechanisms underlying adipose tissue growth.
脂肪瘤是由成熟脂肪细胞构成的常见良性软组织肿瘤,通常表现为生长缓慢、无痛的皮下结节。虽然其潜在病因尚不清楚,但已提出多种因素可能是潜在的促成因素。在一些个体中,会出现多个皮下脂肪瘤,其发生被认为与全身状况或家族易感性有关。激素替代疗法(HRT)常用于管理更年期症状,它通过激素信号通路影响脂质代谢和血管生成;然而,其在脂肪瘤形成中的潜在作用仍不确定。在此,我们报告一例57岁女性在开始激素替代疗法后,大腿和臀部出现多个皮下脂肪瘤的病例。该病例突出了激素变化与脂肪瘤形成之间可能存在的关联,强调了进一步研究脂肪组织生长潜在机制的重要性。
