Keratosis Punctata (Palmaris et Plantaris)

Name of the Condition

• Common name: Keratosis punctata
• Medical term: Keratosis punctata palmaris et plantaris

Summary

Keratosis punctata is a skin disorder characterized by tiny, point-like keratoses (hardened areas) on the palms of the hands and soles of the feet. These small, rough spots can lead to discomfort or cosmetic concerns.

Causes

The exact cause of keratosis punctata is not fully understood, but it is thought to be related to genetic factors and possibly linked to certain skin conditions or systemic diseases.

Risk Factors

• Family history of keratosis punctata or similar skin conditions.
• Existing skin disorders such as psoriasis or eczema may exacerbate the condition.

Symptoms

• Small, hard, round keratotic lesions on the glabrous skin of palms and soles.
• These lesions can be asymptomatic or cause itching and irritation.

Diagnosis

• Primarily through physical examination by a healthcare provider.
• Skin biopsy may be done to rule out other skin conditions with similar presentations.

Treatment Options

• Topical keratolytic agents: Help by softening and removing the thickened skin.
• Emollients: Moisturizers to maintain skin hydration and minimize symptom severity.
• Retinoids: Prescription creams may help in managing more severe cases.

Prognosis and Follow-Up

• Keratosis punctata is a chronic condition that may require ongoing treatment.
• Regular follow-ups with a dermatologist are advisable to manage symptoms and adjust treatments as needed.

Complications

• Secondary infections due to skin cracking can occur if the condition is not properly managed.
• Psychological impact due to cosmetic concerns.

Lifestyle & Prevention

• Regular use of emollients to keep skin moisturized.
• Avoiding triggers such as irritants and abrasive activities that might worsen the lesions.

When to Seek Professional Help

• If lesions are persistently painful, spreading, or showing signs of infection.
• Sudden changes in the appearance of the skin should be evaluated promptly.
