Keratoderma blennorrhagica

Keratoderma blennorrhagica (KB) is a skin condition that is often associated with Reactive arthritis. It is characterized by the development of hyperkeratotic lesions on the palms of the hands and soles of the feet. The condition is rare and is more common in men than in women.

Symptoms

The primary symptom of keratoderma blennorrhagica is the development of skin lesions. These lesions are typically hyperkeratotic, meaning they involve an overgrowth of the top layer of skin. They may appear as yellow-brown, waxy nodules or as a diffuse thickening of the skin. The lesions are typically painless, but may cause discomfort or difficulty walking if they occur on the soles of the feet.

Causes

Keratoderma blennorrhagica is most commonly associated with reactive arthritis, a type of arthritis that occurs in response to an infection in another part of the body. However, it can also occur in the absence of arthritis. The exact cause of the condition is unknown, but it is thought to involve an abnormal response of the immune system.

Diagnosis

The diagnosis of keratoderma blennorrhagica is typically made based on the characteristic appearance of the skin lesions. In some cases, a skin biopsy may be performed to confirm the diagnosis. Other tests may be performed to identify any underlying conditions, such as reactive arthritis.

Treatment

Treatment for keratoderma blennorrhagica typically involves managing the symptoms and any underlying conditions. This may include the use of topical creams to reduce the thickness of the skin lesions, as well as medications to manage any associated arthritis. In severe cases, surgical intervention may be necessary.
