keratoacanthoma

^ http://purl.obolibrary.org/obo/MONDO_0002527

A dome-shaped, rapidly growing skin lesion composed of well differentiated squamous cells. It represents a proliferation of the infundibular epithelium of the hair follicle and its morphologic distinction from a well differentiated carcinoma may be difficult or impossible. Keratoacanthomas affect males more frequently than females and the majority tend to regress spontaneously. It has been suggested that keratoacanthoma represents a distinct subtype of squamous cell carcinoma of the skin. [ NCIT:C3146 ]

comment

Clinically and histologically, it may be confused with a de novo highly malignant squamous cell carcinoma (SCC). However, KA may be viewed as an abortive cancer that only rarely progresses into an aggressive SCC - PMID:8277007.
