Living with Microcystic adnexal carcinoma

A rare skin tumor that most often grows on the face, head, or neck and rarely spreads to distant parts of the body.

Understanding Microcystic adnexal carcinoma

Microcystic adnexal carcinoma is a rare skin tumor that most often develops in the head and neck area.

It usually grows in the middle of the face but can occur on other parts of the body. It is often first noticed as a bump or a yellowish spot on the skin. It frequently grows into nearby tissues, so it is considered an invasive cancer. It rarely spreads to distant parts of the body (metastasizes).

GARD doesn't list a set of symptoms for this condition. Its summary describes how it may first appear:

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
