“…Such tumors may secrete a number of other substances: like kinin, dopamine, histamine, and prostaglandin, causing signs and symptoms such as facial flushing due to widened blood vessels on the face, abdominal pain, diarrhea, bronchoconstriction, and carcinoid heart disease, which often occurred in gastrointestinal tract and respiratory system. 24 , 30 , 31 However, only 3 cases of carcinoid syndrome were reported in more than 100 patients with renal carcinoid. 1 , 32 , 33 In addition, the pathogenesis of renal carcinoid is unclear, although neuroendocrine cells may be developed by metaplasia from tissue of intermediate mesoderm, no argyrophilic cells have been found in normal renal parenchyma.…”

Primary carcinoid tumor of the kidney is an extremely rare well-differentiated neuroendocrine tumor, which is generally a low-grade malignant cancer with a good prognosis. Carcinoid tumors are rarely found in the urinary system. Here, we report a 34-year-old woman with primary renal well-differentiated neuroendocrine tumor who underwent nephron sparing surgery and no evidence of recurrence or distant metastasis was found during routine follow-up. We searched the case of renal carcinoid with the search phrase “carcinoid [title] and kidney [title]” and “carcinoid [title] and renal [title]” using the PubMed and restricted the search to articles published in English since 2013. The clinical manifestations, age, sex, tumor size, location, gross pathology, light microscopy and immunohistochemistry were analyzed. A total of 28 cases of renal carcinoid were retrieved from PubMed. Higher proportion of positive labeling of CgA, Syn, NSE and CD56 are most valuable in the diagnosis of primary renal well-differentiated neuroendocrine tumor. At present, radical nephrectomy remains the gold standard in the curative-intent therapy for well-differentiated neuroendocrine carcinoma of kidney, in metastatic renal carcinoid, long-term use of octreotide may be an effective adjuvant therapy.

“…1,4,5 El sangrado gastrointestinal es infrecuente. 15 Las metástasis ocurren con mayor frecuencia en los ganglios linfáticos regionales y el hígado, pero también se observa en otros sitios, como hueso, piel, tiroides y mamas.2 En el caso de nuestro paciente, cursaba asintomático a pesar de tener una lesión de dimensiones importantes, que no permitía la intubación de íleon terminal y que ya había infiltrado serosa y tenía compromiso ganglionar (2/8) .…”

Los tumores neuroendocrinos (TNE) representan menos del 5% de las neoplasias del tracto gastrointestinal, con origen en células del sistema endocrino difuso. Clínicamente pueden pasar desapercibidas por muchos años, siendo diagnosticadas cuando la enfermedad ya está en un grado avanzado. Se presenta el caso de un paciente varón de 66 años asintomático quien, por un examen de sangre oculta en heces positivo sin anemia, es sometido a estudios endoscópicos, con hallazgo de una tumoración que prolapsa a través de la válvula ileocecal y que impide la intubación de íleon terminal. El paciente es transferido al servicio de cirugía oncológica, donde fue programado para cirugía curativa y actualmente está en controles hasta definir actitud terapéutica.
