This condition is a type of Purpura, which refers to the appearance of purple discolorations on the skin or mucous membranes caused by small blood vessels that have burst.

Causes[edit | edit source]

Purpura of the nail bed can be caused by a variety of factors. These include trauma to the nail bed, certain medications, and underlying medical conditions such as vasculitis or thrombocytopenia. In some cases, the cause of purpura of the nail bed may be unknown.

Symptoms[edit | edit source]

The primary symptom of purpura of the nail bed is the appearance of purple spots or patches under the nails. These spots may vary in size and can affect one or more nails. Other symptoms may include pain or tenderness in the affected nail, and in some cases, the nail may become loose or fall off.

Diagnosis[edit | edit source]

Diagnosis of purpura of the nail bed typically involves a physical examination of the affected nail(s) and a review of the patient's medical history. In some cases, additional tests such as a blood test or a biopsy of the nail bed may be required to confirm the diagnosis and rule out other conditions.

Treatment[edit | edit source]

Treatment for purpura of the nail bed depends on the underlying cause. If the purpura is caused by trauma, treatment may involve protecting the nail bed from further injury. If the purpura is caused by an underlying medical condition, treatment will focus on managing that condition. In some cases, no treatment may be necessary, and the purpura will resolve on its own.
