Association between gastroesophageal reflux and endobronchial carcinoid: a case report.

Children with neurological disorders may suffer from gastroesophageal reflux disease (GERD). Typical symptoms are vomiting, regurgitation and hematemesis. Patients present with respiratory symptoms only in cases with swallowing disorders causing chronic airway aspiration. We report the case of a patient affected by chromosome 8 p deletion syndrome with mental retardation, referred to our unit for suspected GERD. Chest X-ray, performed at admission for coexisting respiratory complaints, showed left lower lobe pneumonia; esophageal pH monitoring and upper endoscopy were normal for GERD. To rule out chronic airway aspiration, gastroesophageal 99 mTc scintigraphy with lung scan 18 to 24 h after a test meal and video fluoroscopy swallowing study were performed, both negative. Two months later, a second episode of left lower lobe pneumonia occurred. A chest CT scan was performed and showed an endobronchial mass; the biopsy taken during the broncoscopy was not conclusive. Surgical excision resulted in a diagnosis of pulmonary carcinoid. Bronchial carcinoids, although rare, should be taken into consideration as a potential cause of recurrent pneumonia even in the presence of demonstrated GERD where severe respiratory infections only occur with coexisting chronic pulmonary aspiration, even in neurologically impaired people.
