# Occupational Lung Disease Causing Allergic Bronchopulmonary Aspergillosis: A Case Report

## TL;DR

This case report describes a man who was misdiagnosed for a year before being correctly identified with a lung disease caused by a fungal infection.

## Contribution

The paper highlights the diagnostic challenges of ABPA in regions with high tuberculosis prevalence through a real-world case.

## Key findings

- ABPA was misdiagnosed as tuberculosis in an Indian patient for one year.
- The patient recovered successfully after a correct diagnosis of ABPA.
- The case underscores the need for improved diagnostic approaches in similar regions.

## Abstract

Aspergillus fumigatus can induce allergic bronchopulmonary aspergillosis (ABPA), an immunological hypersensitivity reaction that frequently exacerbates the symptoms of cystic fibrosis and asthma patients. Due to persistent symptoms, a considerable percentage of patients with ABPA in India, a country where tuberculosis is widespread, are initially misdiagnosed as having pulmonary tuberculosis. We present a case of ABPA in a male industry worker, who was diagnosed after one year of having symptoms and has successfully recovered since.
