Pulmonary mucoepidermoid carcinoma in a 7‐year‐old child

Abstract

AbstractA 7‐year‐old boy presented with exertional dyspnea and cough, initially misdiagnosed as asthma. Imaging revealed a mass obstructing the left main bronchus, later identified as a pulmonary mucoepidermoid carcinoma (MEC). Following surgical sleeve resection, complete tumor removal occurred without malignancy in surrounding lymph nodes, resulting in symptom resolution without additional therapy. Pulmonary MEC, uncommon in pediatric patients, poses diagnostic challenges due to nonspecific symptoms, resulting in delayed diagnosis. Typically managed via complete surgical resection, MEC offers a favorable prognosis, primarily affecting central airways and requiring conservative surgical approaches to preserve lung tissue. This case underscores the diagnostic challenges of primary pulmonary MEC in pediatric patients. It stresses the need to consider unusual causes in pediatric respiratory symptoms and highlights the critical role of precise diagnostic methods and personalized surgical strategies in managing such rare pulmonary malignancies for optimal outcomes.
