Summary
This report details a rare case of chronic dacryocystitis caused by Mycobacterium abscessus. Prompt diagnosis and surgical intervention, followed by extended antibiotic therapy, are crucial for managing this atypical infection.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Dacryocystitis, an infection of the lacrimal sac, is typically caused by Staphylococcus and Streptococcus.
- Atypical pathogens are rarely implicated in dacryocystitis, posing diagnostic and therapeutic challenges.
Purpose of the Study:
- To report a rare case of chronic dacryocystitis caused by Mycobacterium abscessus.
- To highlight the diagnostic and management considerations for atypical lacrimal sac infections.
Main Methods:
- A 62-year-old female patient presented with symptoms of chronic dacryocystitis.
- Surgical drainage and intraoperative culture of the lacrimal sac abscess were performed.
- Post-surgical treatment involved an extended course of antibiotics, including omadacycline and azithromycin.
Main Results:
- Culture results confirmed the presence of Mycobacterium abscessus.
- The patient showed slow but progressive symptomatic improvement following surgery and antibiotic treatment.
- This is the second reported case of dacryocystitis attributed to M. abscessus.
Conclusions:
- Mycobacterium abscessus is a rare but potential cause of chronic dacryocystitis.
- Intraoperative culturing of lacrimal sac abscesses is recommended for identifying atypical pathogens.
- Extended antibiotic therapy is necessary for treating resistant atypical infections like M. abscessus dacryocystitis.

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
