Invasive pulmonary mucormycosis with concomitant lung cancer presented with massive hemoptysis by hugepseudoaneurysm of pulmonary artery

Abstract

Pulmonary mucormycosis is a rare opportunistic invasive fungal infection involving the pulmonary vasculature in immunocompromised patients. Pseudoaneurysm of pulmonary artery in mucormycosis is a rare fatal complication after invasion and rupture of a pulmonary artery. Wereport a patient with diabetes mellitus and incidental lung cancer who developed massive hemoptysis because of a huge pseudoaneurysm of the left pulmonary artery by mucormycosis. Although the patient had been managed by amphotericin B followed by left pneumonectomy for persistent hemoptysis, he died from septic shock and multiorgan failure after surgery. Histologic analysis of a surgical specimen revealed concomitant squamous cell lung cancer.
