Endobronchial Hamartoma Presenting as Recurrent Pneumonia and Chronic Cough.

Pneumonia is an infection of the lungs that can result from various etiologies, including bronchial obstruction. It is estimated that 5.4% of community-acquired pneumonia occurs as a result of an endobronchial obstruction, classifying them as post-obstructive pneumonia. Pulmonary hamartomas are benign and exceedingly rare tumors. These hamartomas are usually asymptomatic and found incidentally on imaging, however, they can cause patients to develop post-obstructive pneumonia. We present a 40-year-old female with cough, fatigue, and recurrent right lower lobe pneumonia. Upon workup with bronchoscopy and biopsy, she was subsequently found to have an endobronchial hamartoma resulting in recurrent pneumonia in the same location. We are happy to report that the patient had a resection of the mass, as well as of the affected lung lobe, and has been pneumonia-free for five months. We hope to encourage a greater index of suspicion for endobronchial masses, including rare tumors, when a patient presents with recurrent pneumonia in the same location.
