“…Calcification of varying sizes which may be central or peripheral [10–12, 16, 21–23, 25, 29, 51, 58], foci areas of haemorrhage [15, 30], necrosis and cystic changes has been documented. Although cases with necrosis have been previously reported [69–71] and also observed in our review [8, 15, 17, 26, 28], necrosis has been reported to be unusual [15, 36, 60, 67, 69]. The cystic changes may be uniloculated or multiloculated [34, 43, 53, 72].…”

“…Most cases arise in the renal parenchyma; however, rare cases arising from the renal pelvis have been reported [20, 36, 68, 69].

“…The nuclei are round to oval, uniform in size, minimally pleomorphic, and with evenly distributed granular salt and pepper chromatin (Figure 3). Focal calcification with hyalinization and focal intraluminal mucin production may be seen [34, 36, 53, 67] and rarely metaplastic ossification has been reported [67, 69]. …”

Context. Primary renal carcinoid tumours are rare. Their pathogenesis is unknown and the clinical presentation is similar to other renal tumours thus posing diagnostic dilemmas for clinicians. Objectives. To review the literature for case reports of primary renal carcinoids. Methods. Literature was extensively searched for case reports for primary renal carcinoids. Reports of metastatic carcinoids to the kidneys were excluded. Results. Approximately less than 90 cases of primary carcinoid tumours of the kidney have been reported in the literature. A total of 29 cases of primary renal carcinoids were reviewed. The mean age of presentation was 48 years (range 29–75) with both right kidney (48.3%) and left kidney (44.8%) being equally affected. 28.6% of the cases reviewed were diagnosed as an incidental finding. The mean followup time was 20 months with 73.1% of patients without evidence of disease after surgical treatment (radical or partial nephrectomy). Primary carcinoid tumours of the kidney are often well differentiated tumours. They are often misdiagnosed because of their rarity and similar presentation with other renal tumours. Conclusions. Primary carcinoid tumours of the kidney are rare tumours with an indolent course with frequent metastasis. Metastatic work up and followup is required in their management.

“…Primary renal carcinoid tumor arising from renal parenchyma or renal pelvis is a rare neoplasm, and approximately 80 cases with such a tumor have been reported thus far (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). However, few studies report on the genetic characteristics of primary renal carcinoid tumor.…”

Abstract. Few genetic studies of renal carcinoid tumor have been conducted thus far. We performed immunohistochemical and genetic examinations on four renal carcinoid tumors. Histologically, the tumors consisted of neoplastic cells with round to oval nuclei. Various growth patterns such as tightly packed cords and trabeculae, ribbon-like, trabecular, sheet-like or solid growth were observed. nuclear chromatin showed a coarse and granular pattern. Immunohistochemically, tumors were positive for chromogranin A and synaptophysin. In the fluorescence in situ hybridization study, three of four tumors revealed monosomy of chromosome 3 (D3Z1), but one tumor showed monosomy of chromosome 13 (D13s319/13q34). Using PCR amplification and fragment analysis of three microsatellite markers (D3s1300, D3s666 and D3s1768) of chromosome arm 3p, one tumor showed loss of heterozygosity at D3s1300 and D3s1768, one tumor was not informative and the analysis of two tumors failed due to low DnA quality. In three cases, the VHL gene status was tested. two tumors showed wild-type, but the analysis of one tumor failed to provide adequate results. In conclusion, we suggest that the abnormality of chromosome 3 is involved in the pathogenesis of renal carcinoid tumor.

Renal carcinoid and horseshoe kidney: A frequent association of two rare entities—A case report and review of the literature

et al. 1998

We report the case of a primary renal carcinoid tumor associated with a horseshoe malformation in a 43‐year‐old man who presented with testicular pain. The tumor was centrally located and purely solid and had features ascribed to hindgut neuroendocrine neoplasia. The relative risk of developing a carcinoid tumor in a horseshoe kidney is estimated to be ×82. J. Surg. Oncol. 1998;68:113–119. © 1998 Wiley‐Liss, Inc.

Carcinoid tumor of the renal pelvis: Report of a case with positive urine cytology

Abstract: A case of histologically and ultrastructurally confirmed carcinoid tumor of the renal pelvis is reported. The patient's urine sediment showed a few groups and sheets of polygonal malignant cells with scant cytoplasm and oval nuclei displaying chromatin clumping and micronucleoli.
