Understanding Adnexal Carcinomas: A Guide for Patients

Adnexal carcinomas (AC) are a group of rare cancers that starts in the adnexal structures of the skin. Skin adnexa refers to additional organs of the skin, which include sweat glands, sebaceous glands, and hair follicles. When cells in these adnexal structures start growing uncontrollably, AC can develop, leading to the formation of these spots. It often appears as a small white or pink skin-colored bump, where it is most commonly found on the face or neck. While it is rare for AC to spread to other parts of the body, it is a slow, deep-spreading skin cancer, often invading nearby nerves and skin tissue. Understanding and recognizing the signs of AC can be crucial for early detection and treatment.
