Abstract
INTRODUCTION Renal cell carcinoma (RCC) is the dominant primary renal malignant neoplasm, encompassing a significant portion of renal tumors. The presence of synchronous yet histologically distinct ipsilateral RCCs, however, is an exceptionally uncommon phenomenon that is rather under-described in the literature regarding etiology, diagnosis, management, and later outcomes during follow-up. CASE PRESENTATION We aim to present the 9th case of a combination chromophobe RCC (ChRCC) and clear cell RCC (ccRCC) in literature, according to our knowledge, for a 69-year-old North African, Caucasian female patient who, after complaining of loin pain and hematuria, was found to have two right renal masses with preoperative computed tomography (CT) and underwent right radical nephrectomy. Pathological examination later revealed the two renal masses to be of different histologic subtypes. CONCLUSION The coexistence of dissimilar RCC subtypes can contribute to diverse prognostic implications. Further research should focus on enhancing the complex, yet highly crucial, preoperative detection and pathological examination to differentiate multiple renal lesions. Planning optimal operative techniques (radical or partial nephrectomy), selecting suitable adjuvant regimens, and reporting long-term follow-up outcomes of patients in whom synchronous yet different RCC subtypes were detected are of utmost importance.

A contemporary guide to chromosomal copy number profiling in the diagnosis of renal cell carcinoma. Urol Oncol 2022; 40:512-524. [PMID: 34092479 DOI: 10.1016/j.urolonc.2021.04.042] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Revised: 04/06/2021] [Accepted: 04/28/2021] [Indexed: 02/07/2023]
Abstract
The routine clinical implementation of molecular methods other than fluorescence in situ hybridization in the evaluation of renal neoplasia is currently limited, as the current standard of care primarily involves a combination of morphologic and immunophenotypic analysis of such tumors. Amongst various molecular techniques, global copy number profiling using single nucleotide polymorphism-based microarrays, colloquially referred to as SNP-arrays, is being increasingly utilized to profile renal tumors, as several subtypes have characteristic recurrent patterns of copy number alterations. Recurrent copy number alterations in common tumor types include loss of chromosome 3p in clear cell renal cell carcinoma (RCC), gain of chromosomes 7 and 17 in papillary RCC and multiple losses in chromosomes 1, 2, 6, 10, 13, 17, and 21 in chromophobe RCC. Such assays are being increasingly utilized in the clinical setting. Herein, we discuss some common clinical applications of such testing that includes high yield diagnostic and prognostic applications. Diagnostic utility includes evaluation of tumor types that are primarily defined by underlying copy number alterations, establishing the underlying subtype in high grade dedifferentiated (unclassified) renal tumors, as well as assessment of loss of heterozygosity, which is an important component in the workup for germline alterations in tumor suppressor genes. Universal adoption of these techniques across clinical laboratories will likely be significantly affected by variables such as cost, reimbursement, and turnaround time.

Tubulocystic renal cell carcinoma: a distinct clinicopathologic entity with a characteristic genomic profile. Mod Pathol 2019; 32:701-709. [PMID: 30622286 PMCID: PMC7549436 DOI: 10.1038/s41379-018-0185-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2018] [Revised: 11/06/2018] [Accepted: 11/07/2018] [Indexed: 11/09/2022]
Abstract
Tubulocystic renal cell carcinoma, a unique tumor, was recently included as a new entity in the World Health Organization classification of renal tumors. It has variably been reported to be related to other renal cell carcinomas, including papillary renal cell carcinoma, fumarate hydratase-deficient carcinoma, and others, likely because many such carcinomas may show variable amounts of tubulocystic architecture. The published data characterizing the molecular features of these tumors are inconsistent. We studied nine "pure" tubulocystic renal cell carcinomas, as defined by International Society of Urologic Pathologists (ISUP) and World Health Organization (WHO), by targeted next-generation sequencing, and fluorescence in situ hybridization for X and Y chromosomes, to investigate if these show any unique characteristics or any overlap with known mutational/molecular profiles or copy number alterations in other subtypes of renal cell carcinoma. All nine tubulocystic carcinomas demonstrated combined losses at chromosome 9 and gains at chromosome 17, as well as, loss of chromosome Y (in 5/5). None of the tumors showed mutational profiles characteristic of other renal neoplasms, including those seen in fumarate hydratase-deficient renal cell carcinoma. Recurrent mutations in chromatin-modifying genes, KMT2C and KDM5C, were detected in two of nine tumors. Thus, tubulocystic renal cell carcinoma, if defined strictly, at the clinical and pathologic level, demonstrates genomic features distinct from other subtypes of renal cell carcinoma. These findings support the contention that tubulocystic renal cell carcinoma should be diagnosed only using strict morphological criteria and only when presenting in a "pure" form; presence of variable papillary, poorly differentiated, or other architectural patterns most likely do not belong to the category of tubulocystic renal cell carcinoma.

Abstract
Twist2 is a member of the basic helix-loop-helix (bHLH) family and plays a critical role in tumorigenesis. Growing evidence proves that Twist2 involves in tumor progression; however, the role of Twist2 in human kidney cancer and its underlying mechanisms remain unclear. RT-PCR and Western blot analysis were used to detect the expression of Twist2 in kidney cancer cells and tissues. Cell proliferation, cell cycle, apoptosis, migration and invasion assay was measured by the Cell Count Kit-8 (CCK8), flow cytometry, wound healing and transwell analysis, respectively. Gene set enrichment analysis (GSEA) was used to identify correlation of Twist2 with ECM-Receptor-Interaction pathway. In this report, we show that Twist2 up-regulated in human kidney cancer tissues compared with normal kidney tissues. Twist2 promotes cell proliferation, inhibits cell apoptosis, augments cell migration and invasion in human kidney cancer-derived cell in vitro, and promotes tumor growth in vivo. Moreover, we found that knockdown of Twist2 decreased the levels of ITGA6 and CD44 which contribute to cell migration and invasion correlated with ECM-Receptor-Interaction pathway. This result indicates Twist2 may promote migration and invasion of kidney cancer cells by regulating ITGA6 and CD44 expression. Therefore, our data demonstrated that Twist2 involves in kidney cancer progression. The identification of the role Twist2 on the migration and invasion of kidney cancer provides a potential appropriate treatment after radical nephrectomy to get a better prognosis that reducing recurrence.

Abstract
The classification of renal cell neoplasia is morphologically based; however, this has evolved over the last 35 years with the incorporation of genetic characteristics into the diagnostic features of some tumors. The 2013 Vancouver classification recognized 17 morphotypes of renal parenchymal malignancy and two benign tumors. This classification included the newly established entities tubulocystic renal cell carcinoma (RCC)), acquired cystic disease-associated RCC, clear cell (tubulo) papillary RCC, microphthalmia transcription factor family translocation RCC and hereditary leiomyomatosis RCC syndrome-associated RCC. In addition to these newly described forms of RCC there are a number of novel tumors that are currently recognized as emerging entities. These are likely to be incorporated into subsequent classifications and include thyroid-like follicular RCC, succinate dehydrogenase B mutation-associated RCC, ALK translocation RCC, tuberous sclerosis complex-associated RCC, and RCC with (angio) leiomyomatous stroma.

Abstract
Tubulocystic carcinoma (TCC) is a very rare renal tumour with unique gross and microscopic features, alternatively considered as low-grade collecting duct carcinoma. Recent studies favoured distinction of TCC from collecting duct carcinoma, and some cases of TCC synchronously coexisting with other renal cell tumour subtypes were described. We report here two new cases of pure (case 1) or mixed (case 2) TCC with fluorescence in situ hybridisation (FISH) analysis, which showed gains of chromosomes 7 and 17 in the pure TCC of case 1, as well as in the TCC and the papillary renal cell carcinoma (PRCC) components in case 2. These data may further support the notion that TCC is more closely related to PRCC.

Abstract
Our knowledge of renal cell carcinoma (RCC) is rapidly expanding. For those who diagnose and treat RCC, it is important to understand the new developments. In recent years, many new renal tumors have been described and defined, and our understanding of the biology and clinical correlates of these tumors is changing. Evolving concepts in Xp11 translocation carcinoma, mucinous tubular and spindle cell carcinoma, multilocular cystic clear cell RCC, and carcinoma associated with neuroblastoma are addressed within this review. Tubulocystic carcinoma, thyroid-like follicular carcinoma of kidney, acquired cystic disease-associated RCC, and clear cell papillary RCC are also described. Finally, candidate entities, including RCC with t(6;11) translocation, hybrid oncocytoma/chromophobe RCC, hereditary leiomyomatosis and RCC syndrome, and renal angiomyoadenomatous tumor are reviewed. Knowledge of these new entities is important for diagnosis, treatment and subsequent prognosis. This review provides a targeted summary of new developments in RCC.

Abstract
In 2004, A new peculiar subtype of renal cell carcinoma, which later received the name of tubulocystic carcinoma (TCC-RC), was recognized. Though the tumor has distinct macroscopic, microscopic and immunohistochemical features, the tumor was previously considered to have some similarities to various other renal cancers. We did an extensive review of literature using PubMed and CrossRef, which yielded more than 80 cases reported from various parts of the world. We evaluated the epidemiology, tumor presentations, pathological characteristics, treatment, and outcome of TCC-RC.

Abstract
Abstract Thyroid-like follicular carcinoma of the kidney (TLFC), a rare neoplasm with low malignant potential, is histologically similar to primary thyroid follicular carcinoma, but characteristically lacks thyroid immunohistochemical markers. We report a case of 34-year old patient with nephrolithiasis. Ultrasound revealed hepatorenal cysts consistent with adult type polycystic kidney disease (ATPKD) and a cytologically confirmed left kidney tumor. Nephrectomy specimen contained sharply demarcated lesion of unusual morphology. Tubular and cystic structures lined by mostly cuboidal cells and filled with amorphous eosinophillic material, reminiscent of follicular carcinoma of the thyroid gland, were diagnostic for TLFC. Thyroid markers were negative. To our knowledge this is the first report of TFLC associated to ATPKD. Brief review of previously published TFLCs, possible relationship between entities and differential diagnosis are discussed.

Abstract
Objective To investigate the clinicopathological features of collecting duct carcinoma (CDC) and improve its diagnosis and treatment. Methods A retrospective analysis was performed with clinical data including follow-up results of five patients with CDC. Results A total of 5 cases, including 4 males and 1 female, were included in this analysis with the average age 54 years (range 42 to 65). Patients mainly suffered from lumbar pain, hematuria, abdominal mass and low grade fever. Four patients underwent radical nephrectomy while another received palliative nephrectomy. Lymph node metastasis occurred in 3 cases and renal hilum fat metastasis happened to 2 other cases. Tumors was located in the renal medulla and presented invasive growth. They had a tubulopapillary architecture with the hobnail-shaped cells protruding into the glandular lumen, and were accompanied by interstitial fibrosis and dysplasia of epithelial cells in collecting ducts adjacent to the tumors. One tumor was staged at AJCC II, two at AJCC III and two at AJCC IV. Postoperative interferon immunotherapy was applied in 2 cases. Patients were followed up for 5 to 18 months and the average survival time was 10 months. Conclusion The CDC exhibits special clinicopathological features, high degree of malignancy and poor prognosis. The diagnosis depends on the histopathological examination. Early detection and early surgical treatment are still the main methods to improve the prognosis of patients with CDC. Virtual Slides The virtual slide(s) for this article can be found here:

Abstract
Tubulocystic carcinoma of the kidney (TCCK) is a tumor entity, which is not yet included in the WHO classification of renal tumors. The histogenesis of this neoplasm is uncertain. This study was undertaken to determine (1) the incidence of TCCK and (2) immunohistochemical and ultrastructural characteristics of those tumors that qualify as TCCK by the current definitions. From January 1, 2003 to December 31, 2012, a total of 615 renal cell carcinomas (RCCs) were seen by the Department of Pathology, University of Maryland Medical Center. Four TCCKs were identified (4/615, <1 %). TCCK is a distinctive group of kidney tumors with a male predominance and noteworthy macroscopic spongy appearance. Microscopically, the tumors were composed of tubules and cysts lined by a single layer of eosinophilic, columnar, cuboidal, flat, or hobnail cells with large nuclei and prominent nucleoli separated by a thin fibrotic stroma. In all TCCKs, the majority of neoplastic cells showed immunohistochemical (CD10(+), RCC(+), vimentin(+), and AMACR(+)) and ultrastructural (abundant long brush border microvilli) characteristics of proximal renal tubules. In few cells, the microvilli were shorter and sparse with cytoplasmic interdigitation analogous to intercalated cells of the collecting ducts. Focal positivity for BerEP4 (a marker preferentially expressed in distal renal tubules) was also noted. The major differential diagnostic considerations are oncocytoma, multilocular cystic renal cell carcinoma, and cystic nephroma/mixed epithelial and stromal tumor of the kidney. TCCK seems to have a favorable prognosis. In the current series, none of the patients had local recurrence or metastatic disease.

Abstract
Metastatic renal cell carcinoma in the gallbladder is extremely rare, with reported frequencies of less than 0.6% in large autopsy reviews. Only 40 cases were reported in the literature. We report a first case of gallbladder polypoid tumor revealing metastatic clear cell renal cell carcinoma, which demonstrates the importance of radiological tests, histology and immunohistochemistry when making a definitive diagnosis. These examinations also allow differentiating metastatic clear cell renal cell carcinoma from other polypoid lesions in the gallbladder with clear cell morphology. Cholecystectomy should be performed to obtain a definitive diagnosis and to improve survival in case of solitary metastatic renal cell carcinoma.
