title: [Primary renal carcinoid metastasizing to distant sites 12 years after the initial diagnosis].
abstract: Primary renal cancinoids are rare, with one hundred cases reported in the literature. Histologically, it is a well-differentiated tumor which shares a morphological pattern similar to that seen in carcinoids identified at other anatomic locations. We report a case of a 45-year-old man with primitive renal carcinoid, with diagnosis made after the detection of liver metastases. The tumour was peculiar given its tubulopapillary architecture, wrongly suggesting a diagnosis of papillary renal carcinoma. This diagnosis was revised 12 years after, following the appearance of other liver, bone and lung metastases.
