Cutaneous horn occurring on the lip of a child

Abstract

Cutaneous horn is a relatively uncommon lesion consisting of keratotic material resembling that of an animal horn. This kind of lesion is more common in Caucasians and in older age groups. The primary lesion underlying the horny material may be benign, premalignant or malignant. The treatment of choice is an excisional biopsy with a narrow margin, because of the possibility of malignancy. The material must be submitted for histopathological evaluation. The first reported case of cutaneous horn arising on the vermillion border of the lower lip in a black child is presented.

Cutaneous Horn

“…They differ from true animal horns in not having a bony core [2] [4]. The earliest documented case of cutaneous horn is from London in 1558 [5].…”

“…Cutaneous horns most frequently occur in sites that are exposed to actinic radiation or burns. Forearm, cartilaginous portion of the ear, legs, and hands may also be affected [2]. They are thought to result from underlying benign, premalignant or malignant pathology, in 61.1%, 23.2% and 15.7% of cases respectively [3].…”

Facial cutaneous horn and skin cancer: Report of two cases

“…Çıkarılan materyalin histopatolojik incelenmesi önerilmektedir. Verruka vulgaris, molluskum kontagiozum ve aktinik keratozda kriyoterapi ile lokal dekstrüksiyon tedavileri öncelikli olarak uygulanabilir 14 .…”

Cutaneous Horn of the Eyelid: Anatomoclinical Implications

“…The clinical diagnosis is established based on its appearance, the lesion being classifi ed as solitary or multiple, straight, curved or twisted, white or yellow [4,5], most often located at the level of the skin on the patient's face [4,6,7]. While the cause leading to the formation of cutaneous horns [8] is unknown, UV radiations are believed to be the trigger of this condition [9].…”
