Although often classified together as sweat glands, the apocrine and eccrine glands are two distinct types of glands, differing in embryologic origin and function. Apocrine glands are derived from the pilosebaceous follicles, which also include the hair follicles and the sebaceous glands. In contrast, the eccrine glands are considered the true sweat glands. This section focuses on tumors of the sebaceous, apocrine, and eccrine glands.
