Keratoacanthoma is a squamoproliferative disorder with varying presentations and subtypes. However, debates persist regarding its classification as a benign and spontaneously resolving tumor, while other authors consider it a rare variant of cutaneous squamous cell carcinoma with metastatic potential. Consequently, there is a lack of standard practice guidelines regarding the workup and management of such lesions. Therefore, invariably, some lesions of keratoacanthoma may be missed due to a low index of suspicion, inadequate workup, or spontaneous resolution without histological evidence. Herein, we present the case of a 46-year-old housewife with a mass over the lower lip who was diagnosed with keratoacanthoma following histopathological examination, which is in contrast with the usual site and exposure history in keratoacanthoma. Additionally, we present a review of the literature on the topic and the controversies associated with the diagnosis and management of keratoacanthoma to aid physicians in suspecting and diagnosing this entity accurately.
