Giant cutaneous horn in an African woman: a case report

Abstract

Introduction: A cutaneous horn is a conical projection of hyperkeratotic epidermis. Though grossly resembling an animal horn, it lacks a bony core. These lesions have been well described in Caucasian patients, as well as in a number of Arabic and Asian patients.

Plantar Cornu Cutaneum Associated with Cutaneous Myxoma

“…With increasing urbanization and improved medical record keeping increasing number of hitherto conceived rare conditions will be reported. Cutaneous horns have been described in many parts of the body [1][2][3][4][5][6][7][8]. A search of the literature however would suggest this to be the first from the sole of the foot.…”

“…This occurred on the scalp following chronic burn scarring. An earlier report on this condition from Sudan was in an Arab [3].…”

“…There have been reports on occurrence in unusual locations such as the lacrimal sac [2], nasal vestibule [4], glans penis [5][6][7] and the lower lip [8]. Little attention has been paid to this morphologic entity in the African races with a report [3] from East Africa in 2007 appearing as probably the first. This occurred on the scalp following chronic burn scarring.…”

“…However most of the reports were in the light skinned races because of its association with sun exposure and actinic keratoses. Over 30% of cases are seen in the head and neck region [3]. There have been reports on occurrence in unusual locations such as the lacrimal sac [2], nasal vestibule [4], glans penis [5][6][7] and the lower lip [8].…”

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].…”
