A cutaneous horn, commonly known as cornu cutaneum is a rare type of skin growth. It is usually cone-shapedand it grows above the surface of the skin. When you look at it, you will notice that it resembles a tiny horn. At the base of the horn, it can either be cribriform flat or nodular, and it contains compacted keratin. This condition can affect anyone, but it is common to older people who are over 60 years.
It affects both men and women, but men have higher chances of getting it. Individuals with fair skin have higher chances of getting a cutaneous horn. Apart from the cone-shaped horn that protrudes from the skin, there are no other symptoms associated with this medical condition.

It is hard to tell whether the cutaneous horn is malignant. However, malignant lesions are common in older people, especially the male.
If the horn has the following features, the patient should be worried. Medical experts say the real cause of the cutaneous horn is unknown. These horns appear on the skin that is always exposed to the sun. Some people believe that exposure to radiation can also trigger the growth of the cutaneous horn. This has been proven right by the higher rate of this condition in the feet and hands. The feet and hands are the parts of the body that are exposed to sunlight.

It is also called a cornu cutaneumwhich is the Latin name for the medical condition. When you look at this lesion it does resemble a small horn, thus giving it its name. At the base it can be crateriform, flat, or nodular and composed of keratin that is compacted.
Although they can affect any age it is most common in older people between the ages of sixty and seventy. It is equally common in both women and men but in men there is a higher risk of this being malignant. It is also more common for people who have fair skin to have a cutaneous horn. Most of them are curved yellow-brown horns that are hard and can either have a border of skin that is thickened or surrounded by skin that is normal.
On the side of the cutaneous horn it can have horizontal ridges that appear terrace-like. Normally the cutaneous horn is taller than twice the width at the base and can vary in size from just a few millimeters to several centimeters. Many times it is described as feeling and looking like a small animal horn. Usually they will appear singularly but can be multiples and occur anywhere on your body. They are most commonly found on areas that are sun-exposed, especially on the forearms, back of the hands, head, and ears.
They can also develop on the shoulder, penis, chest, and neck. Mostly they are benign but they can be pre-malignant or malignant. Approximately forty percent of these cutaneous horns represent lesions called actinic keratoseswhich are pre-cancerous.
The exact cause of a cutaneous horn is still not known but what is known is that many of them appear on skin that has been over exposed to the sun. Some believe that being exposed to radiation can trigger a cutaneous horn which is evidenced by a higher rate of cutaneous horns on the hands and feet. These are the areas that are most exposed to sunlight.
There have also been cases that some people have cutaneous horns that came from burn scars. If the cutaneous horn is benign usually there is no treatment that needs to be done but you do need to see a dermatologist or physician in order to make sure that it is not pre-cancerous or cancerous. If the cutaneous horns are tender or sensitive at the base they are the ones that will most likely be malignant.
If it was benign you need to make sure that you do follow-up visits with your dermatologist or physician to help prevent skin cancer and to make sure that they do not reoccur. If it was cancerous or pre-cancerous follow-up visits are important also to make sure that they got all the cancerous cells. You should also make sure that you are protecting any areas that are exposed to the sun, especially the area where you had a cutaneous horn removed or treated.
You can do this by wearing a hat with a wide brim, wear clothes that cover your legs and arms, and wearing sunglasses. You should also apply sunscreen before you go out in the sun. In order to know if the cutaneous horn is benign or not the dermatologist or physician will have a biopsy done.

Take your dog to the vet for a definitive diagnosis and possible treatment options. Also known as canine keratoacanthomas or infundibular keratinizing acanthomas, cornifying epitheliomas start in the dog's hair follicle, not his skin per se. They consist of keratin, a protein found in skin and hair.
These growths vary in size and may be accompanied by some hair loss around the area. Unlike some benign growths, they will not go away on their own. It is possible for the growth to rupture, which releases keratin and other cystic material onto the dog's coat and skin and requires veterinary attention.
While any dog might develop these horn-like growths, the condition is more common in males and certain breeds. These include the keeshond, Norwegian elkhound, Old English sheepdog, German shepherd, collie, Pekingese, Lhasa apso, Yorkshire terrier, Belgian sheepdog and bearded collie.
Cornifying epitheliomas generally appear on a dog's tail, chest, back or legs. They also might develop on a dog's footpads, so that they truly resemble an extra nail growing in the wrong place. If on the footpad, the growth may or may not cause difficulty walking. If the growth isn't bothering your dog's foot, you can trim it every time you trim your dog's nails. If the growth affects your dog's movement, your vet can surgically excise it.
In most cases, removal of a cutaneous horn isn't necessary, except for cosmetic purposes. However, if the growth is within reach of your dog's mouth, he might chew or lick it frequently, causing wounds to form. He also could scratch it enough to result in lesions. Your vet can remove the growth, but there's always a chance new growths could develop. Your vet can prescribe retinoids, given orally, to eradicate the growths without the need for surgery.

Cornifying Epitheliomas. Affected Breeds. Growth Locations. Surgical Removal. Show Comments.Cutaneous horn or Cornu Cutaneum is a development of a skin lesion that is conical in projection or a cone-shaped bulge that surfaces above the skin.
Cutaneous horn is also called cornu cutaneum, a Latin reference for horn structure, because of its appearance. A common description of the skin problem is its high comparison to a miniature horn. The skin condition can be of harm to the affected, as statistic reports portray. The cutaneous horns are said to overlie the cancerous skin.
Malignancy is likely possible when a tender sensation at the base of the cutaneous horn is felt. However, in most cases, no clinical features present reliable support for it to be benign or malignant.
Further tests are, however, essential to rule out possible malignancy. This skin condition is said to affect people with increasing age.
Those who are 60 to 70 years of age are at most risk for developing cutaneous horn. Fair-skinned individuals are also at risk for cutaneous horn development.

The individuals mentioned become prone the more when they have a clear history of considerable exposure to sun and UV rays. In order to diagnose the condition, a skin biopsy is performed.
A specimen is collected from a simple shave biopsy procedure. The usual affectation of cutaneous horn is the sun-exposed areas of the body. This places the frequently sun-exposed skin a known risk, especially when a person is fair-skinned. The usual body areas affected are the face, pinna earnose, arms, and dorsal hands. The following are the enumerated characteristics of cutaneous horn:. Picture 1 : funnel-shaped growth of Cutaneous Horn that extends from skin base red. Picture 2 : person has a verruca wart with cutaneous horn made up of hard keratin.
Cutaneous horn photo Cutaneous Horn Causes Cutaneous horns basically develop because of precipitating and predisposing factors. A cutaneous horn develops more frequently to the overly sun-exposed parts of the skin, but some cases also present that those sun-protected skin are also affected.
The mechanism of the cutaneous horn starts from the process of hyerkeratosis, usually to the skin surface affected by a hyperprofilerative lesion. The skin condition can either be benign or malignant in form. While some, unfortunately, develops to premalignant actinic keratosis.
Premalignant actinic keratosis can cause for an alarm as it indicates near development of skin cancer. Somehow, the condition is linked to the human papilloma virus, which is a frequent causative agent for infections such as verruca vulgaris.
Nail-like Growth on Dogs
In addition, another virus is involved to the development of cutaneous horn. Poxvirus, molluscum contagiosum, is said to be an occasional causative agent for cutaneous horn.
According to reports, men have been found at risk or have more occurrences of malignant cutaneous horn development at the base lesion. Another risk for cutaneous horn is age; the old-aged individuals as victims of the skin problem. Other risk factors include the following:. Treatment for cutaneous horn is primarily a surgical intervention.
This is the best and ideal treatment of cutaneous horn as to properly identify for presence of malignancy. Usually, those affected of this condition tend to not mind the growth unless they feel any discomfort from it.

Skin, Hair And Nails.As groomers we have only seen 2 or 3 of these nail like growths in our time so far. We thought we might make this page as it seems like something that someone might come across and be concerned about as they are pretty frightful to look at. Pretty Gross, and they grow in all kinds of shapes and sizes, but mostly look something like this of similar size.
Well the name is pretty lose on what they are exactly but it seems the main idea of a Cutaneous Horn is an over production of Keratin in a localised area, often around a hair follicle.
Some say that the name Cutaneous Horn is an umbrella term for anything that is kind of like this, however others sites seem to have specific names for specific things that have specific causes. From what we know of these Cutaneous Horn it is just the over production of Keratin. Keratin is just a fibrous protein that basically hair and nails are made out of. We would always recommend going to the Vet for anything like this, however after a lot of research there is plenty of evidence to say they can crumble and fall off on their own and then heal always keep it clean by bathing in warm water as it can leave and open woundthey might fall off but then re-grow back.
I have heard of people wiggling them and them coming off in their hand, however this might end a bloody mess and we would not suggest playing with them. Vet, of course, we would suggest the Vet.Jcpenney foundation grant application
It might still grow back annoying i know. Although they are not often problematic, not becoming cancerous tumours and rare enough as it is, the reasons we can see to get them removed are mainly to help stop infections. If your dog knocks the Cutaneous Horn it will likely cause bleeding open wound.
If your dog can reach it with its mouth it will likely lick it and chew it making it bleed open wound. Any open wound is an opportunity for infection of other kinds to get it. If your dog can reach it with their mouth they might chew it off and it is a hard, sometimes sharp object and could cause digestive problems if swallowed.
If you find something like this on your dog, i would not panic and I would just call the vet and schedule a normal appointment. Get it checked out and see what the vet says. I would personally get them removed as it seems like something not worth leaving on, but maybe that is an aesthetic preference.

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 and January 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.Cutaneous Horns - Biggest and Best!
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 above the surface of the skin. The lesions typically occurs in sun exposed areas, particularly the face, ear, nose, forearms, and dorsum of hands.
Cutaneous horn cornu cutaneumis a projectile, conical, dense, hyperkeratotic nodule that resembles the horn of an animal [ 1 ]. The horn is composed of compacted keratin. A number of skin lesions can be found at the base of this keratin mound. Cutaneous horns most frequently occur in sites that are exposed to actinic radiation or burns, and hence, are typically found on upper parts of the face.
Other locations include scalp, nose, eyelid, ear, lip, chest, neck and shoulder. Forearm, cartilaginous portion of the ear, leg and back of hands may also be involved [ 2 ].
Keratosis, sebaceous molluscum, verruca, trichilemma, Bowen's disease, epidermoid carcinoma, malignant melanoma, and basal cell carcinoma have all been described in association with cutaneous horns [ 4 ].
For appropriate histopathological diagnosis, this lesion should undergo biopsy at the base of the horn for smaller lesions excision should be considered.
