SWI/SNF protein expression status in fumarate hydratase –deficient renal cell carcinoma: immunohistochemical analysis of 32 tumors from 28 patients
Fumarate hydratase –deficient renal cell carcinoma (FH-RCC) is a rare, aggressive RCC type, originally described in the setting of hereditary leiomyomatosis and RCC syndrome, which is defined by germline FH gene inactivation. Inactivation of components of the switch/sucrose nonfermentable (SWI/SNF) chromatin remodel ing complex is involved in renal medullary carcinoma (SMARCB1/INI1 loss), clear cell RCC (PBRM1 loss), and subsets of dedifferentiated RCC of clear cell, chromophobe, and papillary types (loss of different SWI/SNF components).

Decreased expression of microRNA-26b in locally advanced and inflammatory breast cancer
Advanced-stage breast cancer patients comprise a smaller proportion of breast cancer patients than do early-stage patients and are more likely to experience a poor outcome. Understanding the underlying molecular mechanisms and identifying new biomarkers for treatment in this subgroup of patients is paramount. With the aim of identifying microRNAs that are regulated in advanced-stage breast cancer, we found lower expression of miR-26b, a member of the miR-26 family, in inflammatory breast cancer and noninflammatory locally advanced breast cancer tissue than in normal breast tissue, by quantitative real-time PCR and in situ ...

Loss of ARID1A expression is associated with poor prognosis in patients with gastric cancer
This study observed and analyzed ARID1A expression and its correlation with prognosis in gastric carcinoma. Postoperative sections of 98 patients with primary gastric cancer and 40 patients with gastric benign lesions were examined by immunohistochemistry. ARID1A deficiency was observed in 19.39% of gastric cancer tissues, 4.08% of matched paracancerous tissues, and 2.5% of normal gastric mucosa. (Source: Human Pathology)

Whole Exome Sequencing Identifies Unique Mutations and Copy Number Losses in Calcifying Fibrous Tumor of the Pleura: Report of Three Cases and Review of the Literature
Calcifying fibrous tumor of the pleura (CFTP) is a rare mesenchymal tumor of unknown pathogenesis. The diagnosis often requires exclusion of other common entities. Our aim was to determine if genomic changes were associated with CFTP that could contribute to mechanisms underlying tumorigenesis. Three cases of CFTP with their corresponding uninvolved control lung tissue were identified. Two patients were male, and one was female (age range: 21 –32years). Tumors were multifocal in two cases and solitary in one. (Source: Human Pathology)

IL-13 is produced by tumor cells in Breast Implant Associated Anaplastic Large Cell Lymphoma: Implications for pathogenesis
More than 500 women worldwide have developed a CD30+ T-cell lymphoma around breast implants, strongly suggesting a cause and effect relationship, and designated as breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). The mechanism of lymphomagenesis is unknown. Recently, a bacterial biofilm containing gram negative bacilli was discovered on the surface of breast implants associated with ALCL. We and others have described overexpression of the proto-oncogene JUNB and mutations of JAK1/2, TP53 and STAT3 in BIA-ALCL. (Source: Human Pathology)

Evaluation of the efficacy of the 4 tests (p16 immunochemistry, polymerase chain reaction, DNA, and RNA in situ hybridization) to evaluate a human papillomavirus infection in head and neck cancers: a cohort of 348 French squamous cell carcinomas
In this study, using 348 head and neck SCCs (126 OP SCCs and 222 non-OP SCCs), we evaluated diagnostic performances of different HPV tests in OP and non-OP SCCs: polymerase chain reaction, p16 immunostaining, in situ hybridization targeting DNA (DNA-CISH) and RNA (RNA-CISH), combined p16 + DNA-CISH, and combined p16 + RNA-CISH.

The clinicopathological comparison among nodal cases of idiopathic multicentric Castleman disease with and without TAFRO syndrome
Multicentric Castleman disease (MCD) is a systemic inflammatory disease potentially caused by an increase in the serum interleukin-6 (IL-6) level. Idiopathic MCD (iMCD) is histopathologically classified into three types: plasmacytic (PC), mixed, and hypervascular (hyperV) types. Recently, a unique clinical phenotype with a poor prognosis overlap with iMCD, thrombocytopenia, anasarca, fever, renal failure or reticulin fibrosis, and organomegaly (TAFRO syndrome), has been reported from Japan, but its detailed clinicopathological features remain unclear.
