Infundibulocystic type

The uncommon infundibulocystic variant, found most often on the face, is often confused with the keratotic type.

It is small, well circumscribed, and composed of nests of cells arranged in an anastomosing fashion with little stroma.

There are numerous small infundibular cyst‑like structures containing keratinous material and sometimes melanin.

The stroma may contain amyloid and/or melanin.

Multiple lesions are sometimes present.
