Abstract
The 2016 WHO Classification of Tumors of the Urinary System recognizes microphthalmia transcription factor (MiT) family translocation carcinomas as a separate entity among renal cell carcinomas. TFE3 and transcription factor EB (TFEB) are members of the MiT family for which chromosomal rearrangements have been associated with renal cell carcinoma formation. TFEB translocation renal cell carcinoma is a rare tumor harboring a t(6;11)(p21;q12) translocation. Recently, renal cell carcinomas with TFEB amplification have been identified. TFEB amplified renal cell carcinomas have to be distinguished from TFEB-translocated renal cancer, because they may demonstrate a more aggressive behavior. Herein, we present a TFEB-translocated and a TFEB-amplified carcinoma cases and describe their distinct histological, immunohistochemical, and molecular characteristics. In addition, we review conventional morphology, immunophenotype, genetic background, and clinical outcome of TFEB-rearranged RCCs in the literature, with a special emphasis on important differential diagnoses and the diagnostic approach.

Abstract
The spectrum of primary renal tumors in which clear cells may appear is revisited in this review. The pathologist's viewpoint of this topic is pertinent because not all the tumors with clear cells are carcinomas and not all renal cell carcinomas with clear cells are clear cell renal cell carcinomas. In fact, some of them are distinct entities according to the new WHO classification. The morphological approach is combined with genetics. Renal cell carcinoma related to von Hippel-Lindau disease is reviewed first because many of the genetic disorders underlying this disease are also present in sporadic, conventional renal cell clear cell carcinomas. Subsequently, conventional renal cell clear cell carcinomas, familial, non von Hippel-Lindau-associated renal cell carcinomas, translocation carcinomas, hereditary papillary renal cell carcinomas, carcinomas associated to tuberous sclerosis and to Birt-Hogg-Dubé syndrome, chromophobe renal cell carcinomas, carcinomas associated with end-stage renal disease, and clear cell tubulopapillary carcinomas are reviewed. Finally, epithelioid angiomyolipoma is also considered in this review.

A distinctive translocation carcinoma of the kidney; "rosette forming," t(6;11), HMB45-positive renal tumor: a histomorphologic, immunohistochemical, ultrastructural, and molecular genetic study of 4 cases. Hum Pathol 2011; 43:726-36. [PMID: 22051379 DOI: 10.1016/j.humpath.2011.07.001] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2011] [Revised: 07/01/2011] [Accepted: 07/14/2011] [Indexed: 12/27/2022]
Abstract
To date, only a few cases of "rosette forming t(6;11), HMB45-positive renal carcinoma" have been published. In this article, we contribute further data on 4 cases of this rare entity. Patients were 3 women and 1 man with an age range of 20 to 54 years (median, 23 years). Follow-up (range, 3-5 years; median, 4 years) did not reveal any metastatic events or recurrences. All tumors were well circumscribed and mostly encapsulated with homogeneous gray to tan cut surfaces. No necrosis was seen. All tumors displayed a solid or solid/alveolar architecture and contained occasionally long and branching tubular structures composed of discohesive neoplastic cells and pseudorosettes. The presence of pseudorosettes was a constant finding, but the number of pseudorosettes varied significantly among cases. All cases displayed focal immunoreactivity for the melanocytic marker HMB45, cathepsin K, and vimentin. Melan A, tyrosinase, cytokeratins, CD10, and microphthalmia transcription factor were each positive in 3 of 4 cases. On ultrastructural examination, numerous electron-dense secretory cytoplasmic granules with some resemblance to melanosomes were identified. The pseudorosettes were composed of reduplicated basement membrane material surrounded by small lymphocyte-like neoplastic cells. Using reverse transcription polymerase chain reaction, 2 tumors were positive for the Alpha-TFEB fusion transcript. The presence of the translocation t(6;11)(Alpha-TFEB) was confirmed in 2 analyzed cases. No von Hippel-Lindau tumor suppressor gene mutation, promotor methylation or loss of heterozygosity of 3p was found. Losses of part of chromosome 1 and chromosome 22 were found in one case.

Abstract
OBJECTIVE Recently, a novel renal carcinoma with specific clinical and histological characteristics and translocation t(6;11)(p21.1;q12 or q13) has been identified. We have found 11 cases in the literature, and we are adding another 3 cases. MATERIALS AND METHODS Three cases were found in the Plzen pathological register with approximately 15,000 cases of kidney tumors. There were two females and 1 male, aged 22, 24, and 39 years. RESULTS The sizes of the tumors were 40, 136, and 10 mm. Two tumors were found incidentally; the biggest one was self-palpated by a 24-year-old pregnant patient. Patients are without any signs of disease 42, 20, and 17 months after surgery. CONCLUSION This tumor is a distinctive and rare translocation carcinoma of the kidney [t(6;11), HMB45 positive]. All cases with known clinical data arose in younger people. The malignant potential is probably low.

Abstract
Renal cell carcinomas (RCCs) represent a heterogeneous group of neoplasms, which differ in histological, pathologic and clinical characteristics. The tumors originate from different locations within the nephron and are accompanied by different recurrent (cyto)genetic anomalies. Recently, a novel subgroup of RCCs has been defined, i.e., the MiT translocation subgroup of RCCs. These tumors originate from the proximal tubule of the nephron, exhibit pleomorphic histological features including clear cell morphologies and papillary structures, and are found predominantly in children and young adults. In addition, these tumors are characterized by the occurrence of recurrent chromosomal translocations, which result in disruption and fusion of either the TFE3 or TFEB genes, both members of the MiT family of basic helix-loop-helix/leucine-zipper transcription factor genes. Hence the name MiT translocation subgroup of RCCs. In this review several features of this RCC subgroup will be discussed, including the molecular mechanisms that may underlie their development.

Abstract
Alveolar soft part sarcoma and pediatric renal cell carcinoma share a similar chromosomal abnormality, t(X;17)(p11.2;q25). Recently, it has been suggested that the inactivation of DNA mismatch repair genes hMLH1 and hMSH2 may play an additional role in the pathogenesis of alveolar soft part sarcoma. Immunohistochemical expression of the proteins hMLH1 and hMSH2 is indicative of the activation status of the corresponding genes. We performed immunohistochemistry for hMLH1 and hMSH2 in 4 cases of pediatric renal cell carcinomas with Xp11.2 rearrangements. All cases showed nuclear immunoreactivity for both proteins, although the staining was patchy. Our study demonstrates that inactivation of the DNA mismatch repair genes hMLH1 and hMSH2 does not appear to play a role in the tumorigenesis of pediatric renal cell carcinomas with Xp11.2 rearrangements.

Abstract
A significant proportion of RCCs of children and young adults bear specific chromosome translocations that result in gene fusions that involve members of the MiTF/TFE transcription factor family. These include the Xp11-translocation carcinomas, which bear TFE3 gene fusions, and the renal carcinomas with the t(6;11)(p21;q12), which bear an Alpha-TFEB gene fusion. Both types of translocation result in overexpression of the fusion gene products, such that nuclear labeling for TFE3 or TFEB by immunohistochemistry is a sensitive and specific marker of these respective tumor types. The clinical behavior of these neoplasms relative to conventional, adult-type renal carcinomas remains to be determined, and will be an important area of future investigation.

Abstract
Over the past 6 years, molecular genetic studies have significantly advanced our understanding of pediatric renal neoplasms. The cellular variant of congenital mesoblastic nephroma (but not the classic variant) has been shown to bear the same t(12;15)(p13;q25) and ETV6-NTRK3 gene fusion as infantile fibrosarcoma, a tumor with which it shares morphologic and clinical features. Rhabdoid tumor of the kidney is characterized by deletion of the hSNF5/INI1 gene, which links it to other rhabdoid tumors of infancy that arise in the soft tissue and brain. Primary renal synovial sarcomas and renal primitive neuroectodermal tumors have become accepted entities, and likely comprise a subset of what had previously been termed "adult Wilms tumor." Renal carcinomas associated with Xp11.2 translocations that result in fusions involving the TFE3 transcription factor gene have been delineated, including a distinctive neoplasm that shares the identical gene fusion as alveolar soft part sarcoma. Most recently, a distinctive type of renal neoplasm with a t(6;11)(p21;q12) has been described, and the cloning of the resulting gene fusion links it to the Xp11 translocation carcinomas. Together, these last two translocation-associated tumors represent a significant proportion of pediatric renal cell carcinomas. This review highlights each of these recent advances.

Abstract
MITF, TFE3, TFEB, and TFEC comprise a transcription factor family (MiT) that regulates key developmental pathways in several cell lineages. Like MYC, MiT members are basic helix-loop-helix-leucine zipper transcription factors. MiT members share virtually perfect homology in their DNA binding domains and bind a common DNA motif. Translocations of TFE3 occur in specific subsets of human renal cell carcinomas and in alveolar soft part sarcomas. Although multiple translocation partners are fused to TFE3, each translocation product retains TFE3's basic helix-loop-helix leucine zipper. We have identified the genes fused by the chromosomal translocation t(6;11)(p21.1;q13), characteristic of another subset of renal neoplasms. In two primary tumors we found that Alpha, an intronless gene, rearranges with the first intron of TFEB, just upstream of TFEB's initiation ATG, preserving the entire TFEB coding sequence. Fluorescence in situ hybridization confirmed the involvement of both TFEB and Alpha in this translocation. Although the Alpha promoter drives expression of this fusion gene, the Alpha gene does not contribute to the ORF. Whereas TFE3 is typically fused to partner proteins in subsets of renal tumors, we found that wild-type, unfused TFE3 stimulates clonogenic growth in a cell-based assay, suggesting that dysregulated expression, rather than altered function of TFEB or TFE3 fusions, may confer neoplastic properties, a mechanism reminiscent of MYC activation by promoter substitution in Burkitt's lymphoma. Alpha-TFEB is thus identified as a fusion gene in a subset of pediatric renal neoplasms.

Abstract
Although the centrosome has an essential role in mitosis, its molecular components have not been fully elucidated. Here, we describe the molecular cloning and characterization of the human gene NTKL, which encodes an evolutionarily conserved kinase-like protein. NTKL mRNA is found ubiquitously in human tissues. NTKL is located on 11q13 and is mapped around chromosomal breakpoints found in several carcinomas, suggesting that NTKL dysfunction may be involved in carcinogenesis. Alternative splicing generates two variant forms of NTKL mRNA that encode protein isoforms with internal deletions. When fused to green fluorescent protein, the full-length product and one of the variant proteins are found in cytoplasm. The other variant product also exists in the cytoplasm during interphase, but is found in the centrosomes during mitosis. Endogenous NTKL protein is also localized to the centrosomes during mitosis. This cell-cycle-dependent centrosomal localization suggests that NTKL is involved in centrosome-related cellular functions.

Abstract
Previously, we located three novel human tumor-associated translocation breakpoints in the chromosome 11q13 region between the markers D11S4933 and D11S546. To facilitate the molecular analysis of these breakpoints, we have constructed a continuous sequence-ready cosmid and PAC contig of approximately 350 kb, including the markers D11S4933 and D11S546. In addition, a detailed transcript map was generated. This resulted in the precise positioning of 11 genes and ESTs within the contig, including 4 genes already known to map in the 11q13 region. Three other genes that we positioned within the contig showed homologies to unmapped genes from human and/or other species. Three ESTs were novel. Partial cosmid sequencing resulted in the establishment of the direction of transcription of several of the reported genes. This contig will be instrumental for the detailed characterization of the tumor-associated chromosomal breakpoints and the identification of other 11q13-associated disease genes.
