Final answer:
A steatoma usually appears on the scalp, neck, or back.
Step-by-step explanation:
A steatoma, also known as a sebaceous cyst, is typically found on the scalp, neck, or back. It is a slow-growing, noncancerous cyst that forms beneath the skin. Steatomas usually develop from a hair follicle and are filled with sebum, a waxy substance produced by the skin's sebaceous glands.
