Misdiagnosis of Granulomatosis with Polyangiitis: An Unknown Disease for Pakistan

This case represents the misdiagnosis of granulomatosis with polyangiitis (GPA) as pulmonary tuberculosis (TB). This describes the severe consequences of misdiagnosing GPA, which led to this patient acquiring ESRD and requiring dialysis. Greater awareness of granulomatosis with can prevent mistreatment, as inappropriate treatment of this disease with anti-TB drugs can lead to severe consequences. In conclusion, c-ANCA testing is recommended for all patients showing signs and symptoms of TB, who have positive chest X-ray results but a negative sputum test for acid-fast bacilli, to eliminate GPA, as this disease can be fatal for the patient if it remains undiagnosed.
