Obstructive purpura
Obstructive Purpura
Obstructive purpura (pronunciation: ob-struc-tive pur-pu-ra) is a medical condition characterized by the appearance of red or purple discolorations on the skin that do not blanch when pressure is applied. These discolorations are caused by the obstruction of blood flow in the small blood vessels.
Etymology
The term "obstructive purpura" is derived from the Latin word "obstructio", meaning "a blocking", and the Latin word "purpura", meaning "purple".
Symptoms
The primary symptom of obstructive purpura is the appearance of red or purple spots on the skin. These spots, known as petechiae, are caused by the leakage of blood from the capillaries into the skin. Other symptoms may include fever, fatigue, and joint pain.
Causes
Obstructive purpura can be caused by a variety of conditions that lead to the obstruction of blood flow in the capillaries. These conditions may include vasculitis, thrombocytopenia, and certain infections.
Diagnosis
The diagnosis of obstructive purpura is typically made based on the presence of characteristic skin lesions. Additional tests, such as a complete blood count (CBC) and a biopsy of the affected skin, may be performed to confirm the diagnosis and identify the underlying cause.
Treatment
The treatment of obstructive purpura is primarily aimed at managing the underlying cause. This may involve the use of medications to reduce inflammation and improve blood flow, as well as lifestyle modifications to reduce the risk of further blood vessel damage.
