Introduction
Keratoacanthoma (KA) is a common cutaneous neoplasm, probably derived
from hair follicle cells (1,2). KA is a keratin-plugged, crater-shaped
nodule that arises spontaneously, grows fast, and then typically
regresses. It usually presents as a solitary lesion. However, multiple
lesions in a sporadic form or an inherited manner are possible (2,3).
The most common form of multiple KAs is Ferguson-Smith type. We reported
herein the first Tunisian case of Ferguson-Smith type keratoacanthoma
that occurred in a 41-year-old male patient, with no family history of
this variant.
