Table of Contents
Palmar plantar pustulosis is a chronic skin condition that primarily affects the palms of the hands and the soles of the feet. It is characterized by the presence of small, raised pustules filled with pus. The exact cause of palmar plantar pustulosis is not fully understood, but it is believed to involve an abnormal inflammatory response in the skin.
Certain factors such as genetics, smoking, and exposure to certain chemicals or medications may also play a role in triggering the condition. While the pustules can be uncomfortable and unsightly, palmar plantar pustulosis is not contagious. If symptoms persist, medical evaluation can help manage discomfort and reduce flare-ups.
What are the Types of Palmar Plantar Pustulosis?
Palmar plantar pustulosis primarily affects the palms and soles and can vary in severity and distribution. It is generally considered a localized pustular skin condition rather than a collection of distinct clinical types.
Some related conditions can resemble or occur alongside palmar plantar pustulosis, so accurate diagnosis is important for selecting appropriate treatment.
- Localized Palmar Plantar Pustulosis: Pustules, redness, scaling, and cracking are mainly confined to the palms and soles.
- Severe or Extensive Palmar Plantar Pustulosis: More extensive lesions may affect larger areas of the palms and soles and cause significant pain or functional difficulty.
- Pustulotic Arthro-Osteitis: Some people with palmar plantar pustulosis may also develop inflammation affecting the joints and bones, particularly around the chest wall.
- Acrodermatitis Continua of Hallopeau: This is a distinct localized pustular condition affecting the fingers or toes and should be differentiated from palmar plantar pustulosis.

How Is Palmar Plantar Pustulosis Diagnosed?
To diagnose palmar plantar pustulosis, a dermatologist typically begins with a thorough physical examination of the palms and soles to assess the presence of pustules, redness, scaling, and cracking.
Medical history plays a crucial role in understanding the duration and progression of symptoms, as well as identifying factors such as smoking, medication use, and possible irritant exposure. A skin biopsy may be performed when needed to rule out other conditions and support the diagnosis.
Blood tests or imaging studies are not routinely required but may be recommended when another condition or associated joint or bone involvement is suspected.
- Physical examination of the palms and soles
- Detailed medical and treatment history
- Skin biopsy when the diagnosis is uncertain or another condition needs to be excluded
- Blood tests when needed to evaluate inflammation or other associated conditions
- Additional imaging studies when joint or bone symptoms suggest associated involvement
What are the Treatment Options for Palmar Plantar Pustulosis?

Additionally, maintaining good hand and foot care, using emollients, avoiding smoking, and identifying individual triggers can complement medical treatment. Regular follow-ups with a dermatologist are important to monitor symptoms and adjust treatment when needed.
- Topical corticosteroids: These may help reduce inflammation, redness, and discomfort during flare-ups.
- Vitamin D analogues: Medicines such as calcipotriol may be used to help control skin inflammation and pustule formation.
- Emollients: Moisturizers can help reduce dryness, scaling, and cracking and protect the skin barrier.
