Microcystic adnexal carcinoma

Microcystic adnexal carcinoma (MAC) is a rare sweat gland cancer, which often appears as a yellow spot or bump in the skin. It usually occurs in the neck or head, although cases have been documented in other areas of the body. Most diagnosis occur past the age of 50. Although considered an invasive cancer, metastasis rarely occurs. Main treatments are wide local excision or Mohs micrographic surgery, which ensures that most, if not all, cancer cells are removed surgically.
