Pachyonychia congenita, or PC, is a rare genetic condition that affects the nails, skin, and sometimes the mucous membranes. For the feet and ankles, it often leads to thickened nails, painful calluses, and blisters, especially on weight-bearing areas like the soles. These calluses and blisters can make walking and daily activities extremely uncomfortable, significantly impacting mobility and quality of life. The condition arises from mutations in specific keratin genes, causing the skin and nails to grow abnormally. Pressure from shoes and physical activity worsens symptoms, making proper foot care essential. Treatment focuses on reducing discomfort, such as filing thickened nails, softening calluses, and wearing custom footwear to minimize pressure. A podiatrist can play a vital role in managing PC. If you suffer from this affliction, it is suggested that you schedule an appointment with this foot specialist who can offer specialized care and advice to improve comfort and mobility.

Rare Foot Conditions

The majority of foot conditions are common and can be treated by a podiatrist.  Standard diagnostic procedures are generally used to identify specific conditions and treatment can be rendered. A podiatrist also treats rare foot conditions which can be difficult to diagnose and may need extra attention and care. 

There are many rare foot conditions that can affect children. Some of these can include:

• Freiberg’s disease
• Kohler’s disease
• Maffucci syndrome

Freiberg’s disease - This can be seen as a deterioration and flattening of a metatarsal bone that exists in the ball of the foot. It typically affects pre-teen and teenage girls, but can affect anyone at any age. Symptoms that can accompany this can be swelling, stiffness, and the patient may limp. 

Kohler’s disease - This often targets the bone in the arch of the foot and affects younger boys. It can lead to an interruption of the blood supply which ultimately can lead to bone deterioration. The patient may limp or experience tenderness, swelling, and redness.

Maffucci syndrome - This affects the long bones in a child’s foot leading to the development of abnormal bone lesions. They are benign growths and typically develop in early childhood and the bones may be susceptible to breaking. 

A podiatrist can properly diagnose and treat all types of rare foot conditions. If your child is affected by any of these symptoms or conditions, please don’t hesitate to call our office so the correct treatment method can begin.
