Abstract 

Carcinoid tumors originate from neuroendocrine cells and have an indolent course. Primary carcinoid of the kidney is rare, as renal parenchyma is lacking in the enterochromaffin cells. The aetiopathogenesis is not properly understood as there are very few cases. There are several tests that can be performed pre-operatively, with octreotide scintigraphy being specific. Histopathology helps confirm the diagnosis, and this is further supplemented by immunohistochemistry. IHC stains positive for cytokeratin and synaptophysin in case of carcinoid tumors. While medical treatment helps manage the syndromes that maybe associated with a carcinoid tumor, surgery remains the treatment of choice. These tumors have a low malignant potential, and post-operative chemoradiotherapy is often not indicated. Here we present a case of a middle-aged female with an incidentally detected carcinoid of the kidney. Post-surgery, she remains asymptomatic and has not shown any signs of recurrence thus far.
