What is an acrochordon? | | Fig. 43.1 A, Multiple, small, typical exophytic, light brown acrochordons of the axilla associated with acanthotisis nigricans.

An acrochordon (skin tag, fibroma durum) is a soft, flesh-colored to dark brown, often pedunculated, cutaneous papule usually located on the neck, axilla, or groin (Fig. 43-1A). It is probably the most common mesenchymal neoplasm. Acrochordons are often multiple, usually 1 to 4 mm in size, but occasionally 3 cm or larger in diameter. The larger baglike lesions often also contain some fat and are called soft fibromas or fibroepithelial polyps (Fig. 43-1B). |
