Aggregatibacter actinomycetemcomitans pneumonia mimicking lung cancer in a previously healthy 12-year-old child from Saudi Arabia: a case report
Abstract
Aggregatibacter actinomycetemcomitans formely known as Actinobacillus actinomycetemcomitans is a known part of the normal oral flora. It can sometimes cause oral or rarely extra-oral infections secondary to hematogenous extension or aspiration. It is a rare cause of invasive pneumonia. It can resemble tuberculosis or lung cancer in its presentation. Making the diagnosis in such case is crucial for better management that usually require tissue biopsy. We report a case of Aggregatibacter actinomycetemcomitans invasive pneumonia in a 12-year-old previously healthy boy from Saudi Arabia. After a prolonged course of antibiotics, clinical and radiological follow up showed complete resolution of the infection.
