Siliconomas are rare conditions stemming from uses of silicone injections for soft tissue augmentation, most commonly in the breast and buttocks areas. Siliconomas are known to present with suspicious morphology that mimics cases of embolism or systemic metastasis as the silicone travels through blood and lymphatics. We present the case of a 45-year-old HIV-positive male who presented with siliconomas in the breast region, chest heaviness, shortness of breath, dyspnea, and a physical exam showing gynecomastia. The patient denied any surgeries or injections around his chest. Further imaging showed abnormal fat deposition in the chest and possible metastatic lymphadenopathy to axillary, supraclavicular, and mammillary lymph nodes. Although the complications arising from silicone injections are well documented, the pathogenesis remains unknown, leaving a narrow range of therapeutic options. Despite these shortcomings, diagnostic imaging tools have shown to be vital in the diagnosis and localization of suspected siliconomas.
硅瘤是一种罕见的病症，源于使用硅胶注射进行软组织填充，最常见于乳房和臀部区域。已知硅瘤会呈现出可疑的形态，因为硅胶通过血液和淋巴管流动时，会模仿栓塞或全身转移的病例。我们报告一例45岁的HIV阳性男性病例，该患者乳房区域出现硅瘤，伴有胸部沉重感、呼吸急促、呼吸困难，体格检查显示有男性乳房发育。患者否认胸部周围有任何手术或注射史。进一步的影像学检查显示胸部脂肪沉积异常，腋窝、锁骨上和乳头淋巴结可能有转移性淋巴结病。尽管硅胶注射引起的并发症已有充分记录，但其发病机制仍然未知，治疗选择范围狭窄。尽管存在这些缺点，但诊断成像工具已被证明在疑似硅瘤的诊断和定位中至关重要。
