What is a steatoma commonly referred to as?

A steatoma is commonly referred to as a cyst filled with sebum, which is an oily substance produced by sebaceous glands. This type of cyst develops when the sebaceous gland or duct becomes obstructed, leading to the accumulation of sebum. Typically found on the scalp, face, or neck, steatomas are generally benign and can usually be identified by their characteristic appearance—a soft, movable lump under the skin that may have a small opening.

Understanding the nature of a steatoma helps in differentiating it from other skin conditions. A boil, for instance, is an infection of the hair follicle that results in inflammation and pus formation, while a viral wart is caused by a viral infection and appears as a growth on the skin. Familiarity with these distinctions is important for proper diagnosis and treatment in esthetic practices.
