Paediatric diffuse oesophageal leiomyomatosis with Alport syndrome.

Diffuse oesophageal leiomyomatosis is a rare benign disease in the paediatric population. This report highlights a recent clinical case, together with a narrative review of current world literature.An early middle childhood girl with recurrent lower respiratory tract infections for 2 years was noted to have a retrocardiac lesion on chest X-ray, later confirmed to be an oesophageal mass on CT imaging. She underwent an Ivor-Lewis oesophagogastrectomy and a Heineke-Mikulicz pyloroplasty. Pathology examination revealed type I diffuse oesophageal leiomyomatosis. Alport syndrome was later confirmed following an episode of postoperative haematuria, which was corroborated by electron microscopy examination following renal biopsy.With an oesophageal mass lesion and Alport syndrome, oesophageal leiomyomatosis should be suspected in any patient with a clinical history of dysphagia and/or respiratory symptoms. Endoscopic ultrasound-guided tissue biopsy is valuable for diagnosis of all suspected lesions. Surgical resection is mandatory to effect cure.
