Steatocystoma multiplex is a benign, autosomal dominant congenital condition resulting in multiple cysts on a person's body.

They most often arise on the chest and may also occur on the abdomen, upper arms, armpits and face.

Steatocystomas are thought to come from an abnormal lining of the passageway to the oil glands (sebaceous duct).

Localised, generalised, facial, acral, and suppurative types of steatocystoma multiplex have been described.

Healthcare professionals would look at a combination of a patient's medical history, symptoms, physical exam and other laboratory tests to inform their diagnosis.

In most cases, small incisions (cuts into the skin) allow the cyst and its contents to be extracted through the opening.
