Abstract

Steatocystoma multiplex is a rare, benign, sporadic or familial disorder. Steatocystoma multiplex with extensive calcification is extremely rare. A 57-year-old man presented fever and cough with expectoration for 3 weeks. Chest CT showed bilateral pleural effusion. FDG PET/CT showed diffuse FDG uptake of the bone marrow and multiple hypermetabolic calcified nodules in the scrotum with SUVmax of 7.6. Blood culture revealed septicemia. Skin biopsy of the scrotal nodules revealed steatocystoma multiplex with calcification. Histopathologically, there were rich multinucleated giant cells and lymphocytes in the cyst wall of the steatocystoma, which may contribute to the increased FDG uptake.

摘要

多发性皮脂囊瘤是一种罕见的良性、散发或家族性疾病。广泛钙化的多发性皮脂囊瘤极其罕见。一名 57 岁男性因发热、咳嗽伴咳痰 3 周就诊。胸部 CT 显示双侧胸腔积液。FDG PET/CT 显示骨髓弥漫性 FDG 摄取和阴囊内多个高代谢钙化结节，SUVmax 为 7.6。血培养显示败血症。阴囊结节的皮肤活检显示多发性皮脂囊瘤伴钙化。组织病理学上，皮脂囊瘤囊壁内有丰富的多核巨细胞和淋巴细胞，这可能导致 FDG 摄取增加。
