The ultrasound features of 87 steatocytoma multiplex (SCM) lesions detected in 9 patients are reported. Steatocytoma multiplex is a hamartomatous condition derived from the pilosebaceous duct junction that generates multiple cutaneous cystic lesions. It appeared as clusters of well-defined hypoechoic nodules with mild posterior enhancement in 100% of cases, with both dermal and subcutaneous locations in 67%. No calcification foci were detected within or at the periphery of the lesions. Fifty-six percent of the cases showed signs of hypervascularity in the edge of the nodules, and 44% of the lesions were associated with another dermatologic condition, most frequent being hidradenitis suppurativa (75%), followed by vellus hair cysts (25%). Steatocytoma multiplex shows ultrasound features that allow discrimination from other common cutaneous entities.
报告了9例患者中检测到的87个多发性脂肪细胞瘤（SCM）病变的超声特征。多发性脂肪细胞瘤是一种起源于毛囊皮脂腺导管交界处的错构瘤性疾病，可产生多个皮肤囊性病变。在100%的病例中，它表现为边界清晰的低回声结节群，伴有轻度后方回声增强，67%的病例位于真皮和皮下。在病变内部或周边未检测到钙化灶。56%的病例在结节边缘显示血管增多迹象，44%的病变与另一种皮肤病相关，最常见的是化脓性汗腺炎（75%），其次是毳毛囊肿（25%）。多发性脂肪细胞瘤具有可与其他常见皮肤病变相鉴别的超声特征。
