View detailsEosinophilia
Eosinophilia is characterized by a persistent increase in eosinophil counts in the blood or bone marrow and extensive eosinophil infiltration in tissues. Clinically, it is often associated with various diseases and represents a disease process, particularly a non-specific reaction to parasitic infections, allergic diseases, connective tissue diseases, and tumors. Eosinophilia is classified by the degree of eosinophil elevation as follows: Mild: Eosinophils (0.4–1.5) × 10^9/L Moderate: Eosinophils (1.5–5) × 10^9/L Severe: Eosinophils > 5 × 10^9/L

Allergic vasculitis, also known as hypersensitivity vasculitis, is an allergic reaction caused by drugs or infections. It primarily affects small blood vessels in the skin (arterioles, venules, and capillaries), but can also involve small blood vessels in other organs, leading to multi-system disease. The main manifestations of this disease are palpable purpura and/or petechiae (subcutaneous hemorrhagic spots less than 2 mm in diameter) and ecchymoses (subcutaneous hemorrhagic spots greater than 5 mm in diameter) on the skin. It may be accompanied by symptoms in other systems, including the kidneys, joints, intestines, heart, respiratory system, and nervous system.

View detailsVasculitis
Vasculitis refers to an inflammatory reaction of blood vessels, primarily characterized by inflammation and necrosis of the vessels, and clinically manifested by ischemia in tissues supplied by the affected vessels. Some forms of vasculitis are short-term and self-limiting, resolving spontaneously even without treatment. Others present as chronic inflammatory reactions, requiring medication to control inflammation and prevent acute exacerbations.
