The simultaneous occurrence of different histological types of adjacent neoplasms in the same organ is called a collision tumour, and rarely occurs in the kidney. A 63-year-old female presented to the urology department with a 1-month history of a painless hematuria. The computed tomography scans of the abdomen revealed 2 heterogeneous incidental right renal masses. The patient underwent radical nephrectomy including lymphadenectomy without adjuvant therapy. Histopathological examination showed a type 2 renal collision tumour of the papillary renal cell carcinoma with eosinophilic cytoplasm and pseudo stratified nuclei on papillary cores, and chromophobe renal cell carcinoma characterized by large polygonal cells with transparent reticulated cytoplasm and prominent cell membranes, which exhibited sarcomatoid transformation in the local area. Routine follow-up demonstrated no localor distant metastasis signs of recurrence at 20 months.

Two sporadic cases of eosinophilic solid and cystic renal cell carcinoma (ESC RCC), at our institution, are presented in this study to contribute to the growing literature on this novel renal neoplasm. The first patient was a 38-year-old female with two synchronous renal masses measuring 3.5 and 1.9 cm on preoperative imaging. The second patient was a 44-year-old female with an incidental renal mass measuring 4 cm. Both patients underwent uncomplicated radical nephrectomies. The 1.9 cm mass in the first patient was consistent with clear cell RCC. The dominant mass in the first patient and the tumor in the second patient had microscopic and macroscopic findings in keeping with ESC RCC including a tan appearance, abundant eosinophilic cytoplasm, and CK20+ and CK7− staining. Both patients had an uncomplicated course following surgery with no evidence of local recurrence or distant metastatic disease for 1 and 2 years for the first and second patient accordingly. These cases contribute to a growing body of literature regarding ESC RCC including, to our knowledge, the first reported case of synchronous ESC RCC and clear cell RCC. Further research about this novel renal neoplasm is needed.

Renal adenomatosis is a rare disease characterized by numerous adenomas in bilateral kidneys. A literature review shows that malignant tumors can arise in this condition. The present case describes an oncocytic papillary renal cell carcinoma (PRCC) arising in renal adenomatosis. A 70-year-old man presented with incidentally identified, multiple right renal masses on computed tomography. Right nephrectomy was performed, and the resected kidney revealed numerous radiologically undetected small nodules additionally. Microscopically, the nodules were papillary neoplasms of variable sizes and cytological features. The largest nodule measured 1.6 cm and was composed of oncocytic cells, meeting the diagnostic criteria of oncocytic PRCC. The smaller nodules of papillary adenomas and tiny lesions showing a single papillary ingrowth were also seen. This case exhibits a spectrum of renal papillary neoplasms in a resected kidney and can be a valuable case in the understanding of tumorigenesis.

Renal cell carcinoma is the most common malignancy of the kidney in adults. In children, however, it only accounts for an estimated 1.8 to 6.3% of all pediatric malignant renal tumors. Papillary renal cell carcinoma is the second most common type of renal cell carcinoma in children. We present the case of a 12-year-old boy with a 2-month history of abdominal pain, unexplained weight loss, and gross hematuria. Computed tomography revealed a horseshoe kidney and a well-defined mass of 4 cm arising from the lower pole of the right kidney. Microscopically the tumor was composed of papillae covered with cells with abundant eosinophilic cytoplasm and high-grade nuclei with prominent nucleoli. Immunohistochemistry was performed; EMA, Vimentin, and AMACR were strongly positive while CK7, CD10, RCC antigen, TFE3, HMB-45, and WT-1 were negative. Currently, 10 months after the surgical procedure, the patient remains clinically and radiologically disease-free.

Bilateral renal tumors remain relatively uncommon, accounting for 1-5% of patients with renal cell carcinoma. Most sporadic renal cell carcinomas are unilateral and unifocal. Bilateral involvement can be synchronous or asynchronous and is found in 2-4% of sporadic renal cell carcinomas. We report a case of 70 years old male who was incidentally found to have bilateral renal masses. Right sided radical nephrectomy and left partial nephrectomy was performed. Histopathological examination of the specimen revealed clear cell carcinoma and confirmed R0 resection. The patient was discharged on 7th postoperative day.

Tumour Biopsy

AimsRenal tumour biopsy (RTB) is increasingly recognised as a useful diagnostic tool in the management of small renal masses, particularly those that are incidentally found. Intratumoural heterogeneity with respect to morphology, grade and molecular features represents a frequently identified limitation to the use of RTB. While previous studies have evaluated pathological correlation between RTB and nephrectomy, no studies to date have focused specifically on the role of RTB for the diagnosis of papillary renal cell carcinoma (PRCC) and its further subclassification into clinically relevant subtypes.MethodsThis single-institution study evaluated 60 cases of PRCC for concordance between RTB and nephrectomy with respect to diagnosis, grading and subtyping (type 1/type 2).ResultsWe observed 93% concordance (55 of 59 evaluable cases) between RTB and nephrectomy for the diagnosis of PRCC, although seven tumours (12%) were undergraded on RTB. Subtyping of PRCC on RTB was concordant with nephrectomy in 89% of cases reported as type 1 PRCC on RTB (31/35), but only 40% of cases reported as type 2 PRCC on RTB (4/10). Morphological misclassification of PRCC on RTB was most likely to occur in tumours showing a solid growth pattern. Discordant PRCC subtyping most often occurred in tumours with eosinophilia/oncocytic change.ConclusionThere was good concordance between RTB and nephrectomy for the primary diagnosis of PRCC. Although further subtyping of PRCC can aid therapeutic stratification, this can be challenging on RTB and tumours with overlapping or ambiguous features are best reported as PRCC not otherwise specified pending development of more robust methods to facilitate definitive subclassification.

Multilocular cystic renal cell carcinomas (RCC’s), Unilocular cystic RCC’s and RCC’s with extensive cystic necrosis and unilocular cysts with mural tumor nodules forms a wide category of RCC’s. Cystic RCC’s represent upto 3-14% of all RCC’s.[1] Here we present a case of 68 year old female who is a known case of DM, hypothyroidism, bronchial asthma presenting with complains of pain abdomen since 1 year. She has been a case of renal TB and on ATT 30 years ago. Further the patient was evaluatedand foundto have a small partly exophytic cortical cyst measuring 13x12mm noted in the inter polar region posteriorly along with multiple well defined hyper dense non enhancing cortical and exohytic cysts notes in upper / lower and inter polar regions, largest measuring 1.8x1.7cms in upper pole suggestive of hemorrhagic cysts. A diagnosis of left renal complex cyst was made. Alaporoscopic left partial cystectectomy was done and sent for histopathological examination. Microscopy revealed Cystic clear cell fgv Renal cell carcinoma, Furhman Grade 1(Low grade) within a 0.1cm thickening which was further confirmed with IHC expressing strongly for CK7,PAX8 and CAIXand confirmed the diagnosis as Clear cell Papillary Renal cell carcinoma. Patient is being followed up and no recurrence / metastasis has been reported. This provides us an opportunity to consider an unusual finding of Clear Cell Papillary RCC in a complex renal cyst and to look into the cystic lesion with more importance helping us in avoiding missing a carcinoma as found in the present case.

Abstract Papillary renal cell carcinoma (PRCC) is a rare cancer and is the second most frequent histologic type among all renal cell carcinoma, accounting for up to 15%. A 72-year-old man underwent a right radical nephrectomy 7 years ago with final histopathology diagnosis of type 1 PRCC with negative surgical margins. Five years after surgery, computed tomography scan imaging showed the presence of multiple masses suspicious for node recurrences disease localized in the renal lodge, in the inter-aorto-caval space, at the iliac vessels bifurcation and right common iliac vessels. Patient underwent a robotic retroperitoneal lymphadenectomy. The histopathological examination confirmed the recurrence of type I papillary renal cancer in all the specimens. No further recurrences have been observed at 24-month follow-up after surgery. This report is the first describing a robot-assisted minimally invasive surgical excision for type I papillary renal cancer nodal and renal fossa recurrences.

Pathological Assessment

We report a case of tumour seeding caused by percutaneous biopsy of a papillary renal cell carcinoma detected on pathological assessment of the partial nephrectomy specimen in a 50-year-old male. Whilst percutaneous biopsy of renal masses is considered to be safe and can be a valuable tool in the assessment of certain renal lesions, it is not without risks. This rare complication should be taken into consideration before contemplating its use in a patient.

Renal Mass Biopsy

Pathologic characteristics of extirpated renal cell carcinoma (RCC) specimens <7  cm were reviewed to get better information on technical nuances of renal mass biopsy (RMB). Specimens were stratified according to tumor stage, nuclear grade, size, histology, presence of lymphovas-cular invasion (LVI), necrosis, and sarcomatoid features. When considering pT1 (0–7 cm) tumors pT1b (4–7 cm), RCC masses were more likely to have necrosis (43% vs 16%, P < 0.001), LVI (6% vs 2%, P = 0.024), high-grade nuclear elements (29% vs 17%, P < 0.001), and sarcomatoid features (2% vs 0%, P = 0.006) compared with pT1a (0–4 cm) tumors. Additionally, pT3a tumors were more highly associated with necrosis (P = 0.005), LVI, sarcomatoid features, and high-grade disease (P for all < 0.001) when compared to pT1 masses. For masses <4 cm, pT3a cancers were more likely to demonstrate necrosis (38% vs 16%, P < 0.001), LVI (10% vs 2%, P = 0.037), high-grade nuclear elements (31% vs 17%, P = 0.05), and sarcomatoid features (3% vs 0%, P = 0.065) compared to pT1a tumors. Similarly, for masses 4–7 cm, pathologic T3a tumors were significantly more likely to have sarcomatoid features (16% vs 2%, P < 0.001) and LVI (28% vs 6%, P < 0.001) compared to pT1b tumors. In summary, pT3a tumors and those RCC masses >4 cm exhibit considerable histologic heterogeneity and may harbor elements that are not easily appreciated with limited renal sampling. Therefore, if RMB is considered for renal masses greater than 4 cm or those that abut sinus fat, a multi-quadrant biopsy approach is necessary to ensure adequate sampling and characterization of the mass.
