Lichenoid trikeratosis is a rare, benign skin condition characterized by the presence of multiple, small, rough, skin-colored papules. The condition is often associated with sun-exposed areas of the skin, particularly the hands and forearms. The exact cause of lichenoid trikeratosis is unknown, but it is thought to be related to chronic sun exposure.

Symptoms

The primary symptom of lichenoid trikeratosis is the presence of multiple, small, rough, skin-colored papules. These papules are typically less than 1 cm in diameter and are often found on sun-exposed areas of the skin, such as the hands and forearms. In some cases, the papules may also be found on the face and neck.

Causes

The exact cause of lichenoid trikeratosis is unknown. However, it is thought to be related to chronic sun exposure. Other potential causes include genetic predisposition and immune system abnormalities.

Diagnosis

Diagnosis of lichenoid trikeratosis 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.

Treatment

Treatment for lichenoid trikeratosis typically involves the use of topical corticosteroids to reduce inflammation and itching. In some cases, laser therapy or cryotherapy may be used to remove the papules.
