Bronchial Mucous Gland Adenoma of the Lung: A Rare Tumor: A Case Report

Abstract

Bronchial mucous gland adenoma (BMGA) is a very uncommon, benign lung tumor, defined as a proliferation of seromucous glands in the bronchial lamina propria. The majority arises within the main, lobar, or segmental bronchi. The diagnosis depends on tissue biopsy. Mucous gland adenoma needs to be distinguished from low-grade malignant tumors of the bronchus, most considerably, invasive mucinous adenocarcinoma and low-grade mucoepidermoid carcinoma. We report the case of a 40-year-old man who was operated for a broncho-pulmonary tumor whose anatomopathological study revealed an adenoma of the bronchial mucous glands. Through this case, we present the histological characteristics that led to the diagnosis and discuss the different differential diagnoses.
