A giant fungating tumour on the buttock ? Verrucous carcinoma

Dear Editor,

This is a very interesting case report. An important clinicopathological differential diagnosis in this case is a verrucous carcinoma (very well differentiated squamous cell carcinoma). Histologically, this can look extremely benign and can mimic a seborrhoeic keratosis / benign squamous keratosis. I have seen a number of cases like this, where the initial pathology diagnosis is benign, but after review of the slides and discussion at a multidisciplinary meeting the final diagnosis is a verrucous carcinoma. This differential diagnosis should be considered in this case.
