Mucous gland adenoma is a rare benign tumor arising from the mucous secreting glands of the larger airway mucosa. The majority of the cases are seen in the bronchus, but it has also been described in the trachea or peripheral airways. The tumor is composed of mucus-secreting cells, usually forming glands that grow into the lumen as to form an obstructive mass. There is no predilection for sex or age. We report here a case seen in a 5-year-old girl, to our knowledge the youngest in the consulted literature, who presented to Hospital das Clínicas of Faculdade de Medicina de Ribeirão Preto for investigation and treatment of recurrent pneumonia and lung atelectasis. Bronchoscopy showed a mass obstructing the lower left bronchus and a biopsy of the lesion revealed a benign, although uncharacteristic lesion. Surgical removal of the affected segment, the recommended treatment for this benign lesion, evidenced a mucous gland adenoma. The child recovered well and was completely free of disease when she was lost for follow-up when she was 6 years old.
