cornu cutaneum

Rashmi Gs Phulari, Rajendrasinh Rathore, Trupti Pramod Talegaon, Arpan Shah
Cutaneous horns ( cornu cutaneum ) are uncommon lesions consisting of keratotic material resembling that of an animal horn. It is a conical- or cylindrical-shaped excessive hyperkeratosis of variable size ranging from few millimeters to several centimeters with a variable in size and shape, such as cylindrical, conical, pointed, transversely or longitudinally corrugated, or curved like a ram's horn. The lesions typically occur in sun-exposed areas, particularly the face, ear, nose, forearms and dorsum of hands...

The diagnostic spectrum for scalp lesions is extensive and comprises either benign or malignant features. Cornu cutaneum (CC) is a well-recognized condition; however, its origin and natural course are not always obvious. We present the case of a 78-year-old patient who was diagnosed with intracranial meningioma in 2014 and who subsequently refused treatment. He presented a new scalp lesion, resembling a horn, in the vertex region 1.5 years after his last follow-up. The lesion was excised, and the patient was histopathologically diagnosed as having CC caused by squamous cell carcinoma...

Cutaneous horns (cornu cutaneum) are chronic, dense, hyperkeratotic cutaneous lesions resembling the horn of an animal. These lesions are associated with a variety of benign, premalignant, and malignant cutaneous diseases. Cutaneous horns are often found on the upper parts of the body, such as the face, neck, and shoulders. These lesions rarely occur in areas with no sun exposure, such as the feet. We present the case of a 51-year-old man with two cutaneous horns on the lateral aspect of the third digit of the left foot...

Cornu cutaneum (CC) is a clinical term that describes the horn-like keratotic lesions extending vertically from the skin. Benign, premalignant or malignant lesions may be present at the base of CC. Seborrhoeic keratosis and squamous cell carcinoma (SCC) are the most commonly reported benign and malignant forms, respectively. Basal cell carcinoma (BCC) at the base is rare. Here, we report on an 85-year old female patient having multiple CC lesions, one being giant on her face and two of the lesions diagnosed with BCC at the base...

Cornu cutaneum is a relatively uncommon projectile, irregular, hyperkeratotic nodule that can be seen in places such as scalp, forehead, eyelids, ear, nose, lips, and upper extremities which are subjectable to sunlight. Treatment is surgery with radical margins. Excisional biopsy is enough for treatment of the lesion on head and face. However, there is only little literature about cornu cutaneum on the nasal vestibule. We present an 82-year-old male patient with a necrotic, irregular shaped lesion with pedicle on the left nasal vestibule excised and diagnosed as cornu cutaneum...

A 90-year-old patient presented with a large cutaneous horn (cornu cutaneum) of nine-year duration arising at her right cheek. The lesion was removed by surgery. Histology was reported as cornu cutaneum with a well-differentiated squamous cell carcinoma at its base. Cutaneous horn is morphological designation for protuberant mass of keratin that resembles the horn of an animal. Such lesions appear on sun-exposed skin areas like upper parts of the face and ears in elderly patients. Large cutaneous horns (> 1 cm) tend to be more commonly associated with squamous cell carcinoma compared to smaller cutaneous horns, particularly when present on the face...

A cutaneous horn (cornu cutaneum) is a protrusion from the skin composed of a cornified material. It may be associated with a benign, premalignant, or malignant lesion at the base, masking numerous dermatoses. In a 24-year-old female, a giant cutaneous horn arising from a seborrheic keratosis located on the leg is presented. This case has been reported to emphasize that a giant cutaneous horn may also occur in young patients, even in photoprotected areas, and are not always associated with malignancy.

Cutaneous horn (cornu cutaneum) is a relatively uncommon lesion consisting of a projectile, conical, dense, hyperkeratotic nodule which resembles the horn of an animal. Cutaneous horns most frequently occur in sun-exposed parts and are typically found in the face and the scalp, but may also occur on the hands, eyelids, nose, chest, neck, shoulder and penis. Their occurrence on the penis is uncommon. We report a 42-year-old man presenting with penile cutaneous horn. The association with malignancy on the penis makes proper identification of these lesions essential...

We present a case study of a patient with a rare and disfiguring dermatologic condition known as cornu cutaneum, or giant cutaneous horn (GCH). While this condition has been well described in people of European and Asian ancestry, its presence in African populations is perceived to be rare and has not been reported in the literature until recently. We present the case of cornu cutaneum in a woman of African descent, contributing to the recent evidence that this condition may not be as rare in African populations as believed...

Squamous cell carcinoma is the most common maligne primary tumour of the hand. It is almost always located on the dorsum of the hand, an occurrence in the palm is very rare. Usually these tumours are recognised early because of their clinical presentation and visible location. We report on a case in which the patient presented in our hospital only due to a massive mechanical impairment of his hand function through an oversized squamous cell carcinoma. On the basis of this case the therapeutic algorithm for large squamous cell carcinoma in the palm is illustrated and discussed...

Cornu cutaneum, or giant cutaneous horn (GCH), is an uncommon but disfiguring lesion that may cause the patient considerable distress. The aesthetic implications of such lesions are obvious. The etiology and treatment of GCH are more obscure, both to patients and physicians alike. We present a female patient of African descent with a GCH of the scalp, which represents the first such case to our knowledge outside Africa. The etiology and management of GCH in all races are reviewed.

A cornu cutaneum (cutaneous horn) is a clinical descriptive term referring to a skin tumor having the appearance of an animal horn. Histopathologically, the lesion may be associated with several different tumors. Along with some benign entities such as warts or seborrheic keratoses, a cutaneous horn may be also associated with actinic keratoses, Bowen disease and squamous cell carcinoma. When an underlying malignancy is present, the entire tumor must be removed with careful control of margins. We report a case of a 68-year-old man with a cornu cutaneum-like HPV 45 positive sub-ungual squamous cell carcinoma on the left second toe...

BACKGROUND: Cutaneous horn (cornu cutaneum) is a morphological designation for a protuberant mass of keratin that resembles the horn of an animal. It results from unusual cohesiveness of keratinized material from the superficial layers of the skin or implanted deeply in the cutis. This lesion may be associated with a benign, premalignant, or malignant lesion at the base, masking numerous conditions. METHODS: A retrospective analysis of 48 cases of cutaneous horns of the eyelid treated between 1992 and 2002 has been performed...

BACKGROUND: 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. PATIENTS AND METHODS: 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...
