Sclerodactyly is a condition characterized by localized thickening and tightness of the skin of the fingers or toes. It is often associated with systemic scleroderma, a chronic connective tissue disease.

Symptoms

The primary symptom of sclerodactyly is the tightening of the skin on the fingers or toes. This can lead to difficulty in movement and function of the affected digits. In severe cases, the skin may become so tight that it restricts blood flow, leading to tissue death and gangrene.

Causes

Sclerodactyly is most commonly associated with systemic scleroderma, a disease that results in the overproduction of collagen, leading to the thickening and tightening of the skin. Other conditions that may cause sclerodactyly include Eosinophilic fasciitis, Nephrogenic systemic fibrosis, and Eosinophilia-myalgia syndrome.

Diagnosis

Diagnosis of sclerodactyly is primarily based on physical examination and the patient's medical history. In some cases, a skin biopsy may be performed to confirm the diagnosis.

Treatment

Treatment for sclerodactyly primarily involves managing the underlying condition causing the skin changes. This may include medications to suppress the immune system, improve blood flow, or reduce the production of collagen. Physical therapy may also be beneficial to improve mobility and function of the affected digits.
