[A pulmonary tumor that racks our brains!].

We report the case of a 74-year-old woman who, as part of the follow-up for two breast cancers, presented a 2cm long lung nodule. A microscopic examination of the biopsy under a scanner showed a proliferation of epithelial appearance but whose immunophenotypic profile did not permit a precise diagnosis (negativity of CK7, GATA3, TTF1, negative estrogen receptors but positive progesterone receptors). Wedge resection surgery was performed.

[A case of bronchial mucous gland adenoma: A rare diagnosis that should not be mistaken!].

We report the case of a 32-year-old man, who was admitted for a recurrent pneumopathy. The thoracic computed tomography revealed a small well-circumscribed lesion of the lower right lobe of the lung. Microscopic examination from the biopsy material of the endoscopy concluded a mucoepidermoid carcinoma.
