Unveiling Mycobacterium fortuitum Lung Disease: A Case Linked to Pedicure Practices

TL;DR

A healthy young man developed a lung infection from Mycobacterium fortuitum, likely due to exposure during a pedicure, highlighting the need for broader awareness of this pathogen.

Contribution

This case report highlights a novel link between pedicure practices and M. fortuitum lung disease in a previously healthy individual.

Findings

M. fortuitum was identified in sputum samples from a young male with respiratory symptoms.

The patient responded well to targeted antibiotic therapy.

The case suggests pedicure-related exposure as a potential source of infection.

Abstract

Mycobacterium fortuitum (M. fortuitum) is a rapidly-growing mycobacterium (RGM) that can lead to a variety of infections affecting the lungs, skin, and soft tissue. Pulmonary infections with M. fortuitum primarily affect individuals with pre-existing lung conditions, although exposure through contaminated water sources, such as pedicures and nail salon whirlpool footbaths, has also been documented. We present a case of a previously healthy young male presenting with respiratory symptoms and systemic signs suggestive of infection. Following extensive diagnostic workup, M. fortuitum was identified in sputum samples, leading to a favorable response to targeted antibiotic therapy. This case underscores the importance of considering M. fortuitum in differential diagnoses of pulmonary infections and skin infections, particularly in patients without known risk factors.
