Introduction: Eosinophilic granulomatosis with polyangiitis (EGPA) is characterized by eosinophilic granulomatous vasculitis. Typical symptoms include late-onset bronchial asthma and blood and tissue eosinophilia. In addition to these characteristic symptoms, EGPA can affect important organs such as the skin, kidneys, heart, sinuses, gastrointestinal tract, and nervous system.

Background: The underlying pathophysiology of some occupational diseases such as silicosis involves autoantibodies. An autoantibody, antineutrophil cytoplasmic antibody (ANCA), has been recently reported and is known to be elevated in diseases such as vasculitis; therefore, the disease is currently known as ANCA-associated vasculitis. The risk of ANCA-associated vasculitis is known to be 25 times higher in patients with silicosis than in those without any occupational disease.

Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis is characterised by small vessel necrotising inflammatory vasculitis. Prior to immunosupressant therapy availability it usually led to a fatal outcome. Current treatment has changed ANCA-associated vasculitis into a condition with a significant response rate, although with a not negligible relapse occurrence and cumulative organ lesions, mostly due to drug-related toxicities.

Anti-neutrophil cytoplasmic antibody-associated vasculitides (AAV) represent a heterogeneous multisystem group of disorders typified by necrotising inflammation of smaller blood vessels, classically yielding a pauci-immune, crescentic glomerulonephritis. Without prompt treatment, there is a significant risk of irreversible damage and ensuing renal impairment.Diagnosis is often challenging, exacerbated by the disorder's often vague and insidious presentation.

Vasculitides represent a range of disorders marked by inflammation of blood vessels, often posing significant diagnostic challenges due to their diverse clinical presentations and involvement of multiple organ systems. We present the case of a 26-year-old woman who arrived with hemoptysis and a background of exertional dyspnea, chest pain, and occasional visual disturbances. Initial investigations showed elevated perinuclear anti-neutrophil cytoplasmic antibodies (P-ANCAs) and myeloperoxidase antibodies (MPOs), indicative of microscopic polyangiitis (MPA).
