Actinic keratosis: a case of sun damage in the tropics.

Sun damaged to the skin in the tropics is not an uncommon event. There is need for a high index of suspicion especially in patients with outdoor occupations. Prompt diagnosis and therapy will prevent progression to a cancerous state. We report a case of cutaneous horns secondary to actinic keratosis, a pre-cancerous condition relatively uncommon in Black skin. The importance of histological support in its diagnosis cannot be over-emphasized.
