Cutaneous Horn Removal
The removal of a projecting, keratinised skin growth that resembles an animal horn is known as cutaneous horn removal. These horns, which usually emerge from sun-damaged or precancerous skin lesions, are made of keratin, the same protein found in hair and nails. Different techniques are used to remove growths; for minor horns, basic shaving or trimming is used; for larger or possibly malignant growths, surgical excision is used. Dermatologists determine the best removal technique after evaluating the type of the lesion. To keep an eye out for any indications of a recurrence or underlying skin issues, routine follow-ups are crucial. Subjective horn excision is safe and successful when done under expert supervision.
About Cutaneous Horn Removal
Cutaneous horns are cone-shaped skin protrusions that can arise from various underlying conditions. Their development is influenced by several factors:
-
Sun Exposure: Prolonged exposure to ultraviolet (UV) radiation, mainly from sunlight, is a significant contributor. These horns typically appear on sun-exposed areas, linking chronic sun damage to their formation.
-
Precancerous Lesions: Cutaneous horns often develop from precancerous or cancerous skin lesions. Conditions like actinic keratosis, resulting from cumulative sun exposure, can progress to horn formation and may indicate underlying skin malignancies.
-
Viral Infections: Certain viral infections, such as human papillomavirus (HPV), can lead to excessive keratin production, contributing to the development of cutaneous horns.
-
Genetic Predisposition: Although less common, a genetic tendency towards developing cutaneous horns may exist, especially in individuals with a family history of such skin abnormalities.
-
Age and Gender: These growths are more prevalent in older adults, particularly those over 60, and are observed more frequently in men. Hormonal and age-related changes in skin structure may play a role in their development.
Procedure of Cutaneous Horn Removal
Removing cutaneous horns involves various procedures aimed at safely eliminating these keratinized growths. The choice of method depends on the size, location, and underlying cause of the horn. Here are five common approaches:
-
Shaving or Trimming:
For smaller, non-cancerous horns, dermatologists may use a scalpel or scissors to shave or trim the protruding growth without extensive surgery. -
Cryotherapy:
This method involves freezing the cutaneous horn with liquid nitrogen, causing it to blister and eventually fall off. It’s effective for smaller horns and may require multiple sessions for complete removal. -
Electrosurgery:
Electrosurgery utilizes high-frequency electrical currents to cut and remove the horn. This technique is particularly effective for larger horns and helps control bleeding during the procedure. -
Curettage:
Curettage involves scraping or scooping out the cutaneous horn with a curette, a spoon-shaped instrument. It is often combined with electrosurgery for thorough removal and to reduce the risk of recurrence. -
Surgical Excision:
Larger or potentially cancerous horns may necessitate surgical excision, where the entire growth is removed, and the wound is closed with stitches. The excised tissue is typically sent for pathological examination to rule out malignancy.
