ABSTRACT

Background: Approximately 25% of carcinoid tumors develop in the respiratory system. Neuroendocrine carcinoids represent ~5% of all mediastinal tumors and 1-5% of all intrathoracic neoplasms. They contain numerous neurosecretory granules that synthesize, store and release neurohumoral substances that can induce the carcinoid syndrome.
Clinical case: A 21-year-old male presented with a rapidly progressive paraneoplastic syndrome unleashed by anacute urethritis. Two left mediastinal masses were identified and resected. Postoperative evolution has been uneventful during the first year.
Conclusions: We emphasize the importance of early detection of primary and satellite lesions of these tumors including neurohumoral markers and PET/CT scans as in this case, as well as the participation of a multidisciplinary team.
