Cutaneous Horns
From Wikipedia: Cutaneous horns, also known by the Latin name cornu cutaneum, are unusual keratinous skin tumors with the appearance of horns, or sometimes of wood or coral. They are usually small and localized, but can in very rare cases be much larger. Although often benign, they can also be malignant or premalignant. The cause of cutaneous horns is still unknown, however it is believed that exposure to radiation can trigger the condition. This is evidenced by a higher rate of cases occurring on the face and hands, areas that are often exposed to sunlight. Other cases have reported cutaneous horns arising from burn scars. As with many other wart-like skin conditions, a link to the HPV virus family, especially the HPV-2 subtype has been suggested. |
