What is the medical term for a skin tag?

The medical term for a skin tag is "acrochordon." This term specifically refers to small, benign growths of tissue that typically appear on the skin, often pedunculated, meaning they are attached to the skin by a thin stalk. Skin tags are quite common and usually found in areas where skin rubs against skin or clothing.

Other terms listed have different meanings. "Dermatofibroma" refers to a firm, raised growth that is often benign and can appear in various forms on the skin. "Squamous cell carcinoma" and "basal cell carcinoma" are types of skin cancer, with squamous cell carcinoma arising from squamous cells (the outer layer of skin) and basal cell carcinoma originating from basal cells (the deepest layer of the epidermis). Neither of these terms relates to harmless growths like skin tags. Thus, acrochordon is the precise medical terminology that applies to skin tags.
