relevance score : -100.0%
ReferencesSteatocystoma multiplex (SM)，也称为脂肪囊肿病或表皮多囊病，是一种罕见的良性皮肤疾病，其特征是皮内出现多个大小不等的皮脂囊肿。临床上，SM表现为大量光滑、坚硬、可移动的囊性肿块，通常无症状。这些病变多为圆形，直径从几毫米到几厘米不等。囊肿表面可能呈淡黄色，较深的颜色通常与患者肤色相近。囊肿内的液体通常无味、油性，透明度和颜色可有差异。与典型囊肿不同，囊肿上方的皮肤中心通常没有可见的开口。SM可出现在身体任何部位，但常见于皮脂腺和毛囊丰富的区域，如躯干、颈部、头皮、腋窝、上肢、下肢和腹股沟。
Steatocystoma multiplex (SM, also known as steatocystomatosis, sebocystomatosis, or epidermal polycystic disease) is a rare benign intradermal true sebaceous cyst of various sizes. Clinically, SM presents as asymptomatic, numerous, round, smooth, firm, mobile, cystic papules, and nodules. The lesions are uniform, with a size of a few millimeters to centimeters along the long axis. The superficial lesions are yellowish, and deeper lesions tend to be skin-colored. The fluid in SM is odorless, oily, clear or opaque, milky or yellow. The overlying epidermal skin is often normal, with no central punctum. SM can occur anywhere in the body but is more frequently seen in areas rich in pilosebaceous units such as the trunk (especially the presternal region), neck, scalp, axilla, proximal extremities, and inguinal region.
