Appearance of non-Hodgkin's lymphomas (NHL) and renal cell carcinoma (RCC) in same person has been reported in the literature. There is a higher-than-expected incidence of co-occurrence of these neoplastic disorders. The cause for this association remains speculative. Two epidemiological studies have shown that the observed-to-expected ratio for occurrence of RCC in NHL patients were 1.86 to 2.67. We herein describe five patients with both RCC and lymphoid malignancies, and reviewed possible explanations for the association. In three of the five patients, RCC was diagnosed during lymphoproliferative disease work-up, and remaining two cases had been diagnosed with chronic lymphocytic leukemia 1 and 5 years prior to RCC. All RCC cases were detected during staging of the primary tumor, usually by CT scan and/or ultrasound. Our data are in correlation with the literature that there is an increased association of RCC and NHL more often among male patients, and that the lymphoproliferative disease often presents with extranodal involvement. The specialists should be alerted for this possibility when evaluating patients at diagnosis or during follow-up.

Activation of mammalian target of rapamycin (mTOR) signaling occurs in a wide variety of human tumors and can lead to increased susceptibility to mTOR inhibitors. Temsirolimus, a novel analog of rapamycin, has shown promising preclinical and early clinical anti-tumor activity in various solid and hematologic tumor types, either alone or in combination with chemotherapy or other targeted agents. Randomized phase III trials have already demonstrated significant clinical benefits of treatment with single-agent temsirolimus in advanced renal cell carcinoma and relapsed and/or refractory mantle cell lymphoma. Other malignancies studied in the phase I and II trial settings include glioblastoma, breast cancer, endometrial cancer, non-Hodgkin lymphomas, and multiple myeloma. This article reviews a comprehensive collection of the clinical trial results reported to date for temsirolimus in various solid and hematologic malignancies, as well as current strategies being tested in ongoing trials. The findings with temsirolimus in multiple tumors provide a valuable framework for future development of temsirolimus and other mTOR inhibitors.

The incidence of lymphomas, especially non-Hodgkin's lymphoma (NHL), has shown a steady increase over the last decades. At the same time, the prognosis has improved. Given the longer survival of lymphoma patients, pathological manifestations related to malignancy might become more frequent. In this setting, the kidney is one of the most important solid organs affected by direct or indirect lymphomatous involvement. Kidney involvement can be related to obstruction or treatment-induced toxicity, but more intriguing are 1) direct infiltration (NHL); 2) renal malignancies in patients affected by Hodgkin's disease or NHL; 3) associated glomerular diseases. Primary infiltration is rarely seen, while secondary infiltration is described most frequently in autopsy series, even in the absence of renal failure. These alterations may mimic glomerular and/or interstitial disease. The association with kidney malignancies, mostly renal cell carcinoma but also urothelial tumors in Hodgkin''s disease, is higher in lymphoma patients than in the general population: the relative risk at 10 years is about 1.5. Glomerulonephritis is described in patients with Hodgkin's disease or NHL; in the former minimal change disease is most frequent, in the latter the glomerular pattern varies widely. Glomerulonephritis can precede, be concurrent with, or follow lymphoma manifestations. Renal biopsy is often needed in this setting.

Percutaneous radiofrequency ablation is increasingly used for curative treatment of primary cancers of the kidney. We reviewed our experience of percutaneous sampling performed under computed tomographic guidance with fine needle aspiration biopsy (FNAB) and core biopsy (CB), and we report on the complementary roles of these 2 techniques in a series of 351 consecutive patients undergoing radiofrequency ablation for renal neoplasms. Both FNAB and CB were obtained in 290 cases, of which 156 patients (54%) were positive for neoplasm in both specimens, and 27 (9%) were negative for tumor in both specimens. In 58 (20%) patients, the FNABs were positive, but the CBs were negative, and the reverse occurred in 11 patients (4%). When suspicious interpretations by FNAB and CB are included as positives in the calculations, both their complementary nature and the relative higher diagnostic yield of FNAB persisted. In 25 cases with FNABs positive for neoplasm, the CB allowed a more specific tumor classification. The 19 cases of FNAB which were read as negative/benign had corresponding CBs that were also negative/benign in 13 cases; yet, 6 were diagnostic of renal cell carcinoma not otherwise specified (1 case), renal cell carcinoma clear cell/conventional (4 cases), and non-Hodgkin lymphoma (1 case). These and additional findings illustrate the complementary value of the combination of the 2 biopsy methods for a reliable pretherapy morphologic confirmation of specific renal neoplasms. FNAB has relatively greater sensitivity and utility for on-site evaluation, whereas CB provides an additional sample for more specific subclassification and additional studies.

The incidence of patients with multiple primary tumors has been increasing in recent years. The association between non-Hodgkin lymphomas (NHL) and renal cell carcinoma (RCC) is unclear. The presentation of 10 patients with co-existent NHL and RCC at our institution in the past 3 years led us to explore whether this was a chance association or a statistically significant phenomenon. We used the US Surveillance, Epidemiology and End Results (SEER) program (www.seer.cancer.gov) from 1973 to 2006 to identify a total of 892 445 537 subjects aged 18-84, with known values for race and gender at risk for NHL and RCC. Among these, 181 009 were diagnosed with NHL, 118 122 were diagnosed with RCC and 1039 had both NHL and RCC. This was significantly higher than the expected number of 24 with co-existent NHL and RCC (p < 0.0001). The observed number (O) of RCC after NHL was significantly higher than the expected number (E) (O/E: 1.51; 95% confidence interval [CI] 1.36-1.66), with the O/E ratio remaining elevated across the various follow-up time intervals. The observed number of NHL after RCC was not significantly different from the expected number (O/E: 1.09; 95% CI 0.98-1.22). In univariate analyses, race and gender were significantly associated with an increased cumulative incidence of RCC after NHL. Multivariate analysis with age, race and gender revealed that white males had a higher cumulative incidence of RCC after NHL. These findings suggest that patients with NHL are at increased risk for RCC.

The aim of this study was to determine the histological spectrum of operated cardiac tumors, excluding myxoma, at a tertiary center in India. Between 1995 and 2010, we encountered 188 cases of operated cardiac tumors that had been subjected to histopathological examination. Morphological characterization was done by light microscopy along with histochemical stains. Immunohistochemistry using a panel of antibodies, i.e., vimentin, desmin, myogenin, smooth muscle actin (SMA), epithelial membrane antigen (EMA), cytokeratins, factor VIII-related antigen, S100-protein, synaptophysin, chromogranin, Bcl2, MIB-1, leukocyte common antigen (LCA), CD 3, CD20, CD34, and CD 99 (MIC-2) was performed wherever applicable. Out of the 188 cases, 184 were primary cardiac tumors, including 170 cases of benign cardiac tumors. Among the benign tumors, myxomas were the most frequent ones (168 cases), followed by fibroma (2 cases). Primary malignancy was diagnosed in 14 cases, including undifferentiated sarcomas, primitive neuroectodermal tumor, rhabdomyosarcoma non-Hodgkin lymphoma, angiosarcoma, synovial sarcoma, and leiomyosarcoma. Metastatic (secondary) tumors were seen in four cases, including one each of adenocarcinoma, choriocarcinoma, renal cell carcinoma, and alveolar soft part sarcoma. Hence, out of the total of 188 cases, 20 were non-myxoma cardiac tumors (NMCTs), including 2 benign tumors, 14 malignant tumors, and 4 metastatic tumors. In our series, the majority of cardiac tumors were primary in nature. The malignant primary tumors outnumbered benign ones, excluding myxomas, and the most common malignant histology was undifferentiated sarcoma, as opposed to the literature.

Granulomatous inflammation is a distinctive pattern of chronic inflammatory reaction characterized by accumulation of epithelioid histiocytes and multinucleate giant cells. The cause of granulomas can be infectious or non-infectious. Granulomas have been described within the stroma of malignancies like carcinomas of the breast and colon, seminoma and Hodgkin's lymphoma, where they represent T-cell-mediated reaction of the tumor stroma to antigens expressed by the tumor. Granulomatous reaction in association with renal cell carcinoma (RCC) is uncommon, with only few published reports in the literature. We describe three cases of conventional (clear cell) RCC associated with epithelioid granulomas within the tumor parenchyma.

A 46-year-old woman known with relapsing Hodgkin's lymphoma diagnosed at age 5, treated with repeated cycles of radiotherapy and chemotherapy, presented with severe symptomatic radiation-induced aortic stenosis. She also had other late sequelae of radiotherapy including thyroid cancer, mediastinal fribrosis and left pulmonary fibrosis with severe restrictive lung disease and a newly diagnosed renal carcinoma. Due to the prohibitively high surgical risk and need for urgent treatment, she underwent successful transcatheter aortic valve replacement with transfemoral implantation of a 23 mm Edwards SAPIEN-XT prosthesis, which was performed without valvuloplasty of the noncalcified fibrotic valve. The final result was excellent with reduction of the transaortic gradient and no residual aortic regurgitation.

Angioimmunoblastic T-cell lymphoma is one of the most common subtypes of peripheral T-cell lymphoma (15-20% of all cases), accounting for approximately 1-2% of all non-Hodgkin lymphomas. It often presents autoimmune phenomena including hemolytic anemia, thrombocytopenia, glomerulonephrities and circulating immune complexes. Polyarteritis nodosa is an autoimmune disease characterized by necrotizing vasculitis of medium vessels, which rarely develops in association with hematological malignant disorders. Herein we report the case of a 40-year-old man who underwent lymph node biopsy in the suspicious of sarcoidosis. On the basis of histological and immunohistochemical findings, the diagnosis of angioimmunoblastic T-cell lymphoma was performed. The patient was successfully treated with cytarabine-based regimen for 6 cycles. Three months after the initial diagnosis of angioimmunoblastic T-cell lymphoma, a whole body computed tomography showed a lesion in the lower pole of the left kidney. Renal cell carcinoma was suspected, thus a nephrectomy was carried out. The histological findings were compatible with polyarteritis nodosa. To the best of our knowledge, the association between polyarteritis nodosa and angioimmunoblastic T-cell lymphoma has been described only once. This relation may be secondary to the induction of an autoimmune phenomenon by the lymphoma with the formation of circulating immune complexes, leading to vessels walls injury. A careful evaluation is needed in the management of angioimmunoblastic T-cell lymphoma patients with signs of renal failure in order to avoid delay of treatment and organ damage.

Hematological malignancies with renal cell carcinoma (RCC) are rarely seen. We reported here two cases of coincidence of RCC with multiple myeloma (MM) and Hodgkin's disease (HD). A 69-year-old male patient with tumor that was located at the upper pole of left kidney was admitted to our clinic. Partial tumoral resection was performed and stage-I RCC was diagnosed after the histopathological examination of tumor. Moreover, he was diagnosed with IgG kappa stage-IIA MM as a result of bone marrow examination and serum immunofixation electrophoresis. Radiotherapy, combination chemotherapy, and autologous stem cell transplantation (ASCT) were performed. The patient is still alive who achieve a complete remission. A 53-year-old male patient suffered from cervical lymphadenopathy. He has a story of right radical nefrectomy that has been performed 4 years ago. Stage II-B lymphocyte-predominant HD was diagnosed. Combination chemotherapy was started, but relapse occurred 25 months later. ASCT was not planned due to cardiovascular problems and the patient died. Clinicians should keep in mind the coincidence of RCC with MM and HD.
