Vasospastic macule is a medical condition characterized by the presence of small, flat, non-palpable skin lesions that are typically less than 1 cm in diameter. These lesions are caused by vasospasm, a condition in which blood vessels constrict, limiting blood flow to the area.

Causes

The exact cause of vasospastic macule is unknown. However, it is believed to be related to an abnormal response of the blood vessels to certain triggers such as cold temperature, stress, or certain medications. Vasospasm is the primary cause of these lesions.

Symptoms

The main symptom of vasospastic macule is the presence of small, flat, non-palpable skin lesions. These lesions are typically less than 1 cm in diameter and can appear anywhere on the body. They are often red or purple in color and may change color when exposed to cold temperature or stress.

Diagnosis

Diagnosis of vasospastic macule is typically made based on the characteristic appearance of the lesions. A skin biopsy may be performed to confirm the diagnosis and rule out other conditions.

Treatment

Treatment of vasospastic macule is aimed at managing the symptoms and preventing complications. This may include avoiding triggers such as cold temperature and stress, and using medications to relax the blood vessels and improve blood flow.
