Steatocystoma multiplex - 多发性脂囊瘤
References
Steatocystoma 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病，其特征是皮内多个不同大小的皮脂囊肿。临床上，SM表现为大量、光滑、坚硬、可移动的囊性肿块和肿块，通常没有任何症状。这些病变通常呈圆形且大小均匀，宽度从几毫米到几厘米不等。它们的表面可能呈淡黄色，而较深的颜色通常与肤色相匹配。这些囊肿内的液体通常是无味和油性的，具有不同程度的透明度和颜色。与典型的囊肿不同，囊肿上方的皮肤中心通常没有可见的开口。 SM 可以发生在身体的任何部位，但常见于油腺和毛囊丰富的区域，如躯干、颈部、头皮、腋窝、手臂、腿部和腹股沟区域。
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.

一名 25 岁男子的手臂、胸部和腹部出现皮肤问题。 20 年来，他一直患有无痛性肿块，从胸部开始，在过去 7 年里扩散到手臂。

青春期的发病可能是由于毛囊皮脂腺单位的激素刺激所致。它们最常出现在胸部，也可能出现在腹部、上臂、腋窝和面部。在某些情况下，囊肿可能会遍布全身。
