Cutaneous horns in an African population

World journal of surgical oncology, 2004

Cutaneous horns (cornu cutaneum) are uncommon lesions consisting of keratotic material resembling that of an animal horn. Cutaneous horn may arise from a wide range of the epidermal lesions, which may be benign, premalignant or malignant. In this respective study, we describe our experience of eleven patients with cutaneous horn treated at our centre between January 2000 and January 2004. The clinical, pathological and treatment details were extracted from the case records. Data is presented as frequency distribution. There were 8 male and 3 female patients with a median age of 57 years. Most of the lesions were located on the ear, hand and scalp. Surgical resection was carried out in all the lesions. There were two cases of squamous cell carcinoma, and one case of basal cell carcinoma, other 8 cases were benign. None of the lesions recurred and no adjuvant treatment was given to any of the malignant lesions. Cutaneous horn is a clinical diagnosis that refers to a conical projection...

Cutaneous horns are uncommon lesions that occur as conical projections in various sunexposed parts of the body. They are made of hyperkeratotic material and look similar to animal horns. These lesions lack a central bony core that differentiates them from the animal horns. They are frequently associated with various benign, premalignant, and malignant lesions, and therefore carry a clinical significance. We present a case of a 58-year-old gentleman who presented with a conical projection over the center of the forehead, which was clinically diagnosed as a cutaneous horn. Excision of the horn along with the base was done, and the histopathology revealed benign seborrheic keratosis as the underlying lesion. The excision of small lesions along with their bases or biopsy of the base of large lesions is of paramount importance in the management of cutaneous horns.

Cutaneous horn is a conical, circumscribed, dense hyperkeratotic protrusion from skin with epithelial cornification. It is also known by the Latin name ‘Cornu cutaneum’. This rare medical entity resembles animal horn but histological disparity is present between both. They are more commonly present in sun exposed sites or areas that are prone for actinic radiation, burns and hence frequently seen in forearm and upper part of face. Only few cases have been reported with cutaneous horns in unusual sites. Cutaneous horns occurring in oral cavity or perioral regions are extremely rare. The significance of knowing about this dead keratinous cutaneous horn is that it may occur as a part of or in association with a wide range of underlying pathologies, either malignant, premalignant or benign. Majority are due to benign pathologies. We report an unusual presentation of cutaneous horn in left oral commissure of a 45-year-old gentleman which is an extremely rare perioral location for such an...

Cutaneous horn, a clinical manifestation of hyper-proliferation of compact keratin, can represent a wide array of underlying benign and malignant pathologies. Here we report a unique case of a giant cutaneous horn (7x4x3 cm) that developed on a chronic ulcer in a non sun-exposed area. This case presented challenges in terms of diagnosis and treatment. We also review the literature about this rare condition.

This is a case report of a cutaneous horn, which was difficult to diagnose as benign or malignant. It demonstrates how these lesions can be approached in terms of diagnosis and management.

In a survey of dermatitis diagnosed in Lagos, Nigeria, dermatitis cruris pustulosa et atrophicans, liciien pianus, iichen simplex chronicus, pretibial achromic lesions, and ichthyosiform dry skin are very common; necrobiosis lipoidica diabeticorum and diabetic dermopatiiy are moderately common; sporotriohosis and lichen amyloidosis are occasionally seen, but erythema nodosum is rare. This is the final part of the series on Regional Dermatoses in the African Black. Patients presenting with pretibial dermatoses are very common. The dermatoses that afflict this part of the body are particularly chronic. Table 1 shows the notable dermatoses. Some of the dermatoses, like dermatitis cruris pustulosa et atrophicans, hypertrophic lichen pianus, lichen simplex chronicus, pretibial achromic lesions, and ichthyosiform dry skin are very common; necrohiosis lipoidica and diabetic dermopathy are moderately common; others, such as sporotrichosis and lichen amyloidosis, though uncommon, may give rise to diagnostic problems, if no thought is given to them. While erythema nodosum would be a major consideration among whites, this disease is seen very rarely in the West African.''D ermatitis Cruris Pustuiosa et Atrophicans (Oil Acne; Sycosis Cruris, Vaselinoderma) Clark^ in 1952 lucidly described a pustular dermatosis on the pretibial region among Nigerian patients, and descriptively called it dermatitis cruris pustulosa et atrophicans (DCPA).

Cutaneous horn is a proectile, conical, dense, hyperkeratotic nodule that resembles the horn of an animal. It may arise from any part of body. Its presence is quite rare and most commonly found in the regions of the body mostly exposed to sunlight like scalp, forehead, eyelids, ear, nose, lips and upper extremities. Association with seborrheic keratosis is very common. Very rarely it may be found on hidden areas of the body like penis or neck. Various benign, pre-malignant, and malignant cutaneous diseases have been described as underlying factors for its occurrence. Trauma has also been described as a very rare causative factor in the etiology of cutaneous horn. We are hereby presenting such a rare case of cutaneous horn presenting in the neck region which the patient usually used to remain covered owing to his habit, with the history of trivial fingernail trauma which rapidly progressed to cutaneous horn in four months, suspecting a genetic predisposition for its occurrence. Interestingly there was no underlying pathology found in this case.
