Keratoacanthoma is a rapidly growing epidermal tumour that resembles squamous cell carcinoma both clinically and histologically. It is believed to arise from hair follicles. There is little evidence that keratocanthoma has malignant potential but it may mimic histological features of squamous cell carcinoma.

Trauma, viral infection, sun exposure, and chronic exposure to tar, pitch and petroleum have all been implicated as aetiologic agents.

Surgical excision is thought to produce less scarring than leaving the lesion to resolve spontaneously.
