Keratosis punctata of the palmar creases is a rare, autosomal dominant skin disorder. It is characterized by multiple, tiny "raindrop" keratoses, located predominantly on the palmar creases. The condition is also known as Keratosis punctata palmaris et plantaris.

Signs and Symptoms

The primary symptom of Keratosis punctata of the palmar creases is the presence of small, round, skin-colored papules that are located on the creases of the palms. These papules are typically 1-5mm in diameter and are often described as looking like "raindrops". They may also be present on the soles of the feet, but this is less common.

Causes

The exact cause of Keratosis punctata of the palmar creases is unknown. However, it is believed to be a genetic disorder, as it is often seen in multiple members of the same family. The condition is inherited in an autosomal dominant manner, meaning that an affected person has a 50% chance of passing the disorder on to each of their children.

Diagnosis

Diagnosis of Keratosis punctata of the palmar creases is typically made based on the characteristic appearance of the skin lesions. A skin biopsy may also be performed to confirm the diagnosis.

Treatment

There is currently no cure for Keratosis punctata of the palmar creases, and treatment is typically focused on managing the symptoms. This may include the use of topical creams or ointments to help soften the skin and reduce the appearance of the papules.
