Carcinoids have been classified according to their embryonic origin in the past and are now categorized and classified as neuroendocrine tumors, including low malignant typical carcinoids, moderate malignant atypical carcinoids, and highly malignant large cell neuroendocrine and small cell carcinomas. A typical carcinoid is a previously used term for the current designation of a grade I neuroendocrine tumor, well differentiated, belonging to a group of rare tumors with a good prognosis with metastasis of less than 15% with a five-year survival of more than 90%, rarely producing serotonin. Even this biologically favorable tumor with a relatively low degree of metastasis cannot be underestimated. Case: The following section summarizes the classification of neuroendocrine tumors, their diagnosis and treatment, and the second section presents a specific case of a patient with multiple metastases of an original lung carcinoid (histology at the time of surgery 2012, at the time of using this older version of neuroendocrine tumors) describing its further treatment. Conclusion: In well differentiated neuroendocrine tumors, there is a significant risk of metastasis despite their radical surgery; their dispensarization is therefore necessary.
