Polyarteritis Nodosa With Complications: A Diagnostic Challenge and Management Dilemma.

Polyarteritis nodosa (PAN) is a rare autoimmune vasculitis characterized by the inflammation of medium-sized arteries throughout the body. This case report presents the clinical course of a 48-year-old female patient who experienced a complex diagnostic journey and complications during the management of PAN. The patient initially presented with dry skin, rash, and pruritus, which led to an extensive evaluation. Despite multiple visits and investigations, the definitive diagnosis of PAN was delayed. Eventually, the patient was diagnosed with PAN based on skin biopsy findings demonstrating vasculitis and inflammation of blood vessel walls. The treatment course was further complicated by the development of steroid-induced diabetes and recurrent vasculitis symptoms. Recurrence of symptoms, including rashes and neuropathy, necessitated adjustments in therapeutic interventions. This case highlights the challenges encountered in managing both PAN and its associated complications and emphasizes the importance of a multidisciplinary approach and improved patient compliance to optimize treatment outcomes.
