Two Rare Diseases, One Patient: A Case Report of Mucormycosis and Granulomatous Polyangiitis

Area of Science:

• Medical Mycology
• Rheumatology
• Immunocompromised Host Infections

Background:

• Mucormycosis is a life-threatening fungal infection, primarily affecting immunocompromised individuals, and commonly involves the sinonasal and cerebral regions.
• Granulomatous polyangiitis (GPA), or Wegener's granulomatosis, is a rare autoimmune vasculitis affecting small to medium-sized vessels, often presenting with upper respiratory, pulmonary, and renal manifestations.

Observation:

• This report details a 40-year-old female patient presenting with concurrent symptoms indicative of both mucormycosis and GPA.
• The patient exhibited clinical features consistent with both a severe fungal infection and systemic vasculitis.

Findings:

• The simultaneous diagnosis of mucormycosis and GPA in a single patient is exceptionally uncommon.
• The patient received a combination therapy including corticosteroids and antifungal medications.

Implications:

• This case underscores the importance of considering opportunistic infections like mucormycosis in patients with autoimmune diseases, especially those on immunosuppressive therapy.
• The successful management highlights the potential efficacy of combined antifungal and anti-inflammatory treatment in rare co-infections.
• Further investigation into the interplay between vasculitis and fungal susceptibility in immunocompromised individuals may be warranted.
