[Giant skin horn].

Cornu cutaneum is the clinical designation for skin tumours caused by a number of benign, premalignant or malignant conditions, the commonest of which are: actinic keratosis, verruca vulgaris, seborrheic keratosis and squamous cell carcinoma. A case of giant cornu cutaneum measuring 9 x 1.5 cm is reported. The tumour was removed from a patient who had had this increasing tumour for 30 years. It had been pared from time to time but had not caused inconvenience of significance on account of local traditional clothing, culture and religion.
