    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.
