Palpable purpura
Palpable purpura
Palpable purpura (/pælˈpeɪbəl ˈpɜːrpʊrə/; from Latin palpabilis, "able to be touched or felt", and purpura, "purple") is a type of purpura that can be felt on the skin due to inflammation of the blood vessels (vasculitis).
Definition
Palpable purpura is characterized by small, raised, red or purple spots on the skin that can be felt when touched. These spots, which are typically 0.5 to 1 cm in diameter, are caused by bleeding under the skin (hemorrhage).
Causes
Palpable purpura is most commonly caused by an inflammation of the blood vessels (vasculitis), which can result from a variety of conditions such as Henoch-Schönlein purpura, cryoglobulinemia, and septicemia. Other potential causes include certain medications, infections, and autoimmune diseases.
Symptoms
In addition to the characteristic skin lesions, symptoms of palpable purpura may include joint pain (arthralgia), abdominal pain, and kidney problems. In severe cases, it can lead to serious complications such as kidney failure.
Diagnosis
Diagnosis of palpable purpura typically involves a physical examination and may be confirmed through a skin biopsy. Additional tests may be performed to determine the underlying cause of the condition.
Treatment
Treatment for palpable purpura focuses on addressing the underlying cause of the condition. This may involve medications to reduce inflammation and suppress the immune system, as well as treatment for any associated conditions.
