Can keratoacanthoma turn into a SCC?
Follow patients with a history of keratoacanthoma for development of new primary skin cancers (SCC in particular). It has been reclassified as SCC-KA type to reflect the difficulty in histologic differentiation. Uncommonly, keratoacanthomas may exhibit an aggressive growth pattern.

Treatments are not successful for many people with generalized eruptive keratoacanthoma.
