A type of benign skin tumour which disappears after a few months.
A papule (small superficial bump on the skin) or nodule (solid mass of tissue) with a central crater that appears on sun-damaged skin. The papules or nodules may disappear on their own. Keratoacanthomas should be treated by a dermatologist because, although they are benign (not cancerous), they closely resemble tumors of squamous cell carcinoma.

A firm nodule, appearing singly on the skin and growing to around 2 cm across in about six weeks, gradually disappearing during the next few months. Men are affected more often than women, commonly between the ages of 50 and 70. Keratoacanthomas occur on the nose, face, hands, and fingers and sometimes on the scalp or neck. The cause is not known. Although the nodules disappear spontaneously they may leave an unsightly scar, therefore treatment by curettage, cautery, or excision and suture is often carried out.
A common benign tumor that has a mound-shaped body with a central keratin-filled crater. The lesion clinically and histologically resembles squamous cell carcinoma of the skin, and may be related to this cancer.
A benign skin growth termed as a nodule, frequently appearing in older individuals, primarily on the face or arm. Its cause remains uncertain, though prolonged exposure to intense sunlight over the years or extended usage of immunosuppressant drugs might play a role. Initially, the nodule resembles a minor wart, but within approximately eight weeks, it enlarges to a diameter of 1-2 cm. Despite typically vanishing gradually after this period, surgical excision is often advised to avert scarring.
