[Cornu cutaneum].
We report on 62 cases of cornu cutaneum. In contrast to the general opinion that the majority of these lesions arise on the basis of an underlying actinic keratosis or a squamous cell carcinoma, on histological examination we found actinic keratoses in only 25% and squamous cell carcinomas in only 3.2% of cases; 58% of all lesions were identified as common warts. We therefore recommend removal of these skin lesions by the shaving technique followed by electrodesiccation of the base. This has the advantage of supplying the histopathologist with a representative specimen for histological examination and avoiding an unnecessarily large surgical excision. In the rare cases of histologically confirmed squamous cell carcinoma, these lesions can be excised in a second session.
