Peripheral pulmonary hamartoma with haemoptysis from the non‐adjacent bronchus

Abstract

We report a rare case of peripheral pulmonary hamartoma that caused haemoptysis from the non‐adjacent bronchus. A 54‐year‐old man was admitted to our hospital because of haemoptysis. Contrast‐enhanced chest computed tomography revealed a tumour measuring 25 × 24 mm in the left lower lobe. Fluid was observed around the pulmonary artery in addition to the consolidation of the lingular segment of the left lung. Bronchoscopy confirmed continuous bleeding from the lingular bronchus, and surgery was planned. The patient was promptly diagnosed with pulmonary hamartoma intraoperatively, and tumour enucleation was performed. The haemoptysis resolved after surgery, and the patient was discharged on post‐operative day 10. As peripheral hamartoma does not generally cause haemoptysis, we suspected that the haemoptysis occurred due to the unusual condition in which the bleeding from the tumour reached the non‐adjacent lingular branch along the pulmonary artery sheath.

Pulmonary aspergilloma coexisting with hamartoma in post pulmonary tuberculosis: A case report

“…Hamartomas are one of the most common benign pulmonary tumors [ 11 ]. Hamartoma comprises cartilage, connective tissue, muscle, fat, and bone [ 5 ].…”

“…Even though it is rare, hamartoma can also cause hemoptysis [ 6 ]. Kitamura et al reported hemoptysis from non-adjacent bronchus in peripheral pulmonary hamartoma [ 11 ]. Active TB can also have hemoptysis presentation.…”

“…Endobronchial pulmonary hamartoma can cause obstructive bronchial complications. Hamartoma with bronchial obstruction can be accompanied by cough, phlegm, and chest pain [ 11 , 14 ].…”
