L85.2
Keratosis punctata (palmaris et plantaris)
Clinical Classification Guidelines
Medical Intelligence & Overview
Keratosis punctata, also known as punctate keratosis, is a skin condition characterized by small, rough, keratin-filled bumps primarily on the palms of the hands and soles of the feet. This condition falls under the ICD-10 code L85.2 and is usually benign, although it can be a cosmetic concern for some individuals. The bumps are typically clustered and may vary in size and appearance, often leading to a thickened or rough skin surface in the affected areas.
Causes & Symptoms
Clinical Causes: Genetic predisposition: Some cases are inherited and run in families. Environmental factors: Repeated friction, pressure, or exposure to certain chemicals may contribute. Keratogenous factors: Abnormal keratin production causes the accumulation of keratin in skin pores. Underlying health conditions: Rarely, keratosis punctata can be associated with other skin or systemic conditions, such as psoriasis or ichthyosis. Age-related changes: The condition often appears in middle-aged or older adults but can occur at any age.
Key Symptoms: Small, punctate, keratin-filled bumps on the palms and soles. Clusters of rough or gritty skin, often feeling like tiny bumps or warts. Potential skin thickening or hyperkeratosis in affected areas. Minimal to no discomfort, although some may experience mild irritation or dryness. Bumps may sometimes be tender or cause slight itching, especially if irritated.
Diagnostic & Treatment
Diagnosis Path: Diagnosis is primarily clinical, based on an examination of the skin and the characteristic appearance of the lesions. A dermatologist may perform a skin scraping or biopsy if the diagnosis is uncertain or to exclude other skin conditions. Dermoscopy or additional skin tests might be used to differentiate keratosis punctata from similar skin disorders.
Treatment Protocols: While keratosis punctata often does not require treatment, options to improve skin appearance or comfort include:
