What is a steatoma?

A steatoma is a type of benign tumor that is filled with sebum, which is an oily substance produced by sebaceous glands in the skin. It typically presents as a firm, movable lump beneath the skin and is commonly referred to as a sebaceous cyst. The formation occurs when the sebaceous glands or hair follicles become obstructed, leading to the accumulation of sebum.

This condition is mostly harmless and does not usually cause pain or discomfort, although it can become inflamed or infected in some cases. Understanding what a steatoma is and its characteristics is essential for estheticians, as it helps distinguish between various skin conditions and informs appropriate treatment or referral options for clients.
