At histologic analysis, an infiltrative pattern of growth is apparent, with the cells arranged in nests and cords ( , Fig 11b ). Sarcomatoid and rhabdoid (S/R) renal cell carcinoma (RCC) are highly aggressive tumors with limited molecular and clinical characterization. Cases of adult renal cell carcinoma with rhabdoid features have been reported in the literature, usually in association with conventional clear cell and papillary tumors. Clear cell renal cell carcinoma is also called conventional renal cell carcinoma. Rhabdoid component was dominant and had been intermixed with sarcomatoid componen. Microscopic. Little is known of renal cell carcinomas (RCCs) that exhibit rhabdoid features. If this process is unilateral then the problem originates from the ureteral orifice up to the pelvis. OBJECTIVE: To further characterize the rhabdoid phenotype in adult renal cell carcinoma and to determine its origin by genetic analysis. Renal cell carcinoma (RCC) is divided into two major groups based on histology: clear cell or non-clear cell RCC (ie, RCC of variant histology). Little is known of renal cell carcinomas (RCCs) that exhibit rhabdoid features. Renal cell carcinoma (RCC) with rhabdoid differentiation is thought to portend a poor prognosis, similar to RCC with sarcomatoid differentiation. Pathology Outlines Clear Cell Sarcoma. Keywords: Carcinoma, renal cell, Pathology, molecular, Immunohistochemistry, Classification Background Renal cell carcinomas (RCCs) encompass 1â3% of hu-man malignancies and 75â80% of adult kidney cancers. Sarcomatoid renal cell carcinoma (SRCC) with rhabdoid features is a rare tumor with aggressive behavior and poor prognosis. Rhabdoid cells and osteoclastic giant cells are infrequently seen in SCC. If kidney function is impaired enlarged kidney cyst is one of possible answers. Renal cell carcinoma with rhabdoid features: an aggressive neoplasm. Numerous grading systems have been proposed, initially focusing upon a constellation of cytological features and more recently on nuclear morphology. Little success has been reported in treating these patients. There are two types of papillary renal cell carcinoma. A rhabdoid component may be observed among renal clear cell carcinomas but also in papillary carcinomas, chromophobe cell carcinomas, or collecting duct carcinomas.3,4,12,13 Rhabdoid cells are not specific to kidney neoplasms and are also described in lung carcinoma, thyroid carcinoma, gastrointestinal adenocarcinoma, or sarcoma.4â18 In the kidney, RCCs with rhabdoid ⦠The grading schema of renal cell carcinoma (RCC) is based on the microscopic morphology of a neoplasm with hematoxylin and eosin (H&E) staining. RCC with sarcomatoid features showed a higher dedifferentiated component and perineural invasion (27.5 vs. 13.5%, p=0.003 and 28.9 vs. 3.4%, p=0.006, respectively) than RCC with rhabdoid features, while the former showed a higher proportion of neutrophilic inflammation (44.8 vs. 22.2%, p=0.04) and arose more frequently over high grade RCC (55.9 vs. 90.5%, p<0,001). Despite rhabdoid features are lethal tumors and are associated with higher grades, radical nephrectomy with lymph node dissection increases survival rate. Clear cell renal cell carcinoma with rhabdoid features is a rare histopathologic variant of renal cell carcinoma (RCC) recently recognized.

Sarcomatoid and rhabdoid (S/R) renal cell carcinoma (RCC) are highly aggressive tumors with limited molecular and clinical characterization. Classification of renal cell carcinomas has become more challenging. This type of RCC arises from intercalated cells of collecting ducts 1,2. Most of them have Xp11.2 t translocations/TFE3 gene fusions with two subtypes: RCC with t(X; 17) (p11.2; q21) and RCC with t(X; 1) (p11.2; p34). We herein have analyzed 32 undifferentiated RCCs having in common an undifferentiated (anaplastic) phenotype, prominent rhabdoid features, or both, irrespective of the presence or absence of conventional RCC component. In the kidney, rhabdoid tumors are typically found in children, whereas only rare examples have been reported in adults.

Adult renal epithelial neoplasms are a heterogeneous group with varying prognosis and outcome requiring sub-classification. The objective of this study was to determine the incidence of RCC with rhabdoid attributes and characterize the histologic, immunophenotypic, and ultrastructural features by retrospective analysis of 480 consecutively identified cases of RCC in radical nephrectomy specimens. Renal cell carcinoma with a rhabdoid feature is managed mainly with radical nephrectomy and lymph node dissection as in our case. The aim of the present study was to evaluate the validity of potential prognostic parameters of clear cell renal cell carcinoma (ccRCC) recommended by the 2012 International Society of Urological Pathology (ISUP) Consensus Conference in the Japanese population. 6.

Type 2 is more aggressive and grows more quickly. Most renal pelvic transitional cell carcinomas demonstrate exophytic growth. The kidneys are located on either side of the spine towards the lower back. Sarcomatoid and rhabdoid features represent forms of dedifferentiation of RCC tumors and can occur in the same tumor or independently of each other 3. These features can develop over any background RCC histology, including clear cell, papillary, and chromophobe RCC.
