Verrucous cyst

A type of cyst characterized by a wart-like appearance

Verrucous cyst is a type of epidermoid cyst that presents with a wart-like appearance. These cysts are benign and typically occur on the skin. They are characterized by their verrucous, or wart-like, surface, which distinguishes them from other types of cysts.

Presentation

Verrucous cysts are usually found on the skin and can appear anywhere on the body. They are often small, round, and have a rough surface. The cysts are filled with keratin, a protein that is a key component of skin, hair, and nails. The surface of the cyst may resemble a wart, which is why they are described as verrucous.

Pathophysiology

The formation of verrucous cysts is similar to that of other epidermoid cysts. They develop when epidermal cells proliferate in a confined space, leading to the accumulation of keratin. The verrucous appearance is due to the hyperkeratosis of the overlying skin.

Diagnosis

Diagnosis of a verrucous cyst is typically made through clinical examination. A dermatologist may identify the cyst based on its characteristic appearance. In some cases, a biopsy may be performed to confirm the diagnosis and rule out other conditions such as squamous cell carcinoma.

Treatment

Treatment for verrucous cysts is not always necessary unless they cause discomfort or cosmetic concerns. Options include:

• Surgical excision: Complete removal of the cyst and its capsule to prevent recurrence.
• Cryotherapy: Freezing the cyst with liquid nitrogen.
• Laser therapy: Using laser to remove the cyst.

Prognosis

Verrucous cysts are benign and have an excellent prognosis. They do not typically recur after complete surgical removal. However, if the cyst is not entirely removed, it may recur.
