[Primary microcytic carcinoma of the trachea].

Primary microcytic tumors of the trachea are very rare. Among them, primary microcytic carcinoma of the trachea has been described very few times. We present the case of a 44-year-old man with hemoptysis and asthenia, in which the thoracic radiography was normal. However, the bronchofibroscopy detected a microcytic carcinoma localized at the distal third of the trachea with adenopathies and hepatic metastasis. Complete remission was achieved with chemotherapy, remaining the patient free from the disease 10 months after the diagnosis.
