Keratoacanthoma management: results of a survey of UK dermatologists and surgeons

Abstract

Distinction of keratoacanthoma (KA) from squamous cell carcinoma (SCC) is challenging. Management is controversial, with some advocating prompt surgical excision and others monitoring to allow for spontaneous resolution¹. The controversy is compounded by rare reports of metastasis². And yet the benign natural history of KA is supported by various studies, including a systematic review of 455 cases with no cases of metastasis or death¹, and observational studies confirming spontaneous resolution¹.
