Mucoepidermoid lung carcinoma in a pediatric patient confused with pneumonia

Mucoepidermoid carcinoma (MEC) is a common type of salivary gland malignancy; however, rarely, MEC can arise from the lung. This disease has a non-specific presentation and is often overlooked. Histologically, MEC can be classified into low-grade and high-grade forms. Surgical resection is the optimal treatment for low-grade tumors. In this article, we report a case of MEC in a 5-year-old girl who was initially misdiagnosed with pneumonia. The histological results revealed MEC. Thus, clinicians and radiologists should consider the possibility of this rare entity in patients who fail to respond to antibiotic treatments, even among the pediatric population.
