The Telltale Signs:
Recognizing hypersensitivity vasculitis can be challenging due to its varied presentation. The following are the hallmark symptoms that often point toward its diagnosis:
-
Palpable Purpura: Palpable purpura is a classic feature of hypersensitivity vasculitis characterized by small, raised purple or red spots on the skin. These lesions typically occur on the lower extremities but can appear anywhere.
-
Skin Rash: Alongside palpable purpura, individuals with hypersensitivity vasculitis may develop a more generalized rash, which can be itchy or painful.
-
Joint Pain: Joint pain and swelling are common in hypersensitivity vasculitis, mimicking symptoms of other autoimmune diseases like rheumatoid arthritis.
-
Gastrointestinal Symptoms: In severe cases, hypersensitivity vasculitis can affect the gastrointestinal tract, leading to abdominal pain, nausea, vomiting, and even gastrointestinal bleeding.
