Cornu cutaneum – Past and present

Cutaneous horn has been a source of controversy throughout the history. It evoked interest nearly half a millennium before and continues to do so. Cornu cutaneum has been found to be associated with several pre-malignant and malignant skin conditions. The pre-malignant conditions commonly include actinic keratoses and Bowen’s disease. Uncommonly, it is due to the presence of an underlying squamous cell carcinoma. Thus, an effort is needed to determine the pathology present at the base of the horn for proper management of the disease. Wide excision biopsy is a common denominator in the therapy of this peculiar disorder.
