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. Formally, this is a clinical diagnosis for a "conical projection above the surface of the skin."[1] 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.[2]

Etiology
The cause of cutaneous horns is still unknown, but 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.[3] As with many other wart-like skin conditions, a link to the HPV virus family, especially the HPV-2 subtype has been suggested.[4]
Prominent cases
- Zhang Ruifang, aged 101 (living in Linlou Village, Henan province, China), has grown a cutaneous horn on her forehead, resembling what those who have examined her and her family call "Devil's Horns." Notably, this growth has expanded to reach a total of 6 centimeters in length. Another is forming on the opposite side of her forehead.[5]
- Liang Xiuzhen, aged 87 (living in Guiyan village in Ziyang City, Sichuan province, China) grew a 13 cm (5.1") pointed horn from her forehead, earning her the nickname "Unicorn Woman".[6]
- Huang Yuanfan, aged 84 (living in Ziyuan, China).[7]
- Madame Dimanche, called Widow Sunday, a French woman living in Paris in the early 19th century, grew, in six years from the age of 76, a 24.9 cm (9.8") horn from her forehead before it was successfully removed by French surgeon Br. Joseph Souberbeille (1754–1846). A wax model of her head is on display at the Mütter Museum, The College of Physicians of Philadelphia, US.[8]
Mortality/Morbidity
The lesion at the base of the keratin mound is benign in the majority of cases. Malignancy is present in up to 20% of cases, with squamous cell carcinoma being the most common type. The incidence of squamous cell carcinoma increases to 37% when the cutaneous horn is present on the penis.[9] Tenderness at the base of the lesion is often a clue to the presence of a possible underlying squamous cell carcinoma.
Treatments
As the horn is composed of keratin, the same material found in fingernails, the horn can usually be removed with a sterile razor.
However, the underlying condition will still need to be treated. Treatments vary, but they can include surgery, radiation therapy, and chemotherapy.
