    Effectiveness and safety of two 18-gauge needle types on native and allograft renal biopsies.
    Ann Diagn Pathol 2017 Jun 5;28:1-6. Epub 2017 Feb 5.
    Department of Pathology, Laboratory Medicine, University of Toronto, Canada. Electronic address:
    Percutaneous biopsy is a key diagnostic tool for both native and allograft kidney diseases. Adequacy criteria vary, but at a minimum, a biopsy should allow the pathologist to reach a diagnosis and provide prognostic information such as the degree of interstitial fibrosis and tubular atrophy (IF/TA) and percentage of glomerulosclerosis. Whereas most studies use glomerular counts as a surrogate for biopsy adequacy, the amount and preservation of tubulointerstitium is equally important, considering IF/TA is a major prognostic parameter for most medical renal diseases.

    Department of Pathology, Dokkyo Medical University Koshigaya Hospital, Koshigaya, Saitama, Japan.
    Lanthanum carbonate is a popular chemical which is administered for patients with end-stage kidney disease to reduce the absorption of phosphate, and lanthanum deposition in the gastroduodenal mucosa has recently been reported. The aim of this study was to assess whether any histologic changes of the gastric mucosa are related to the deposition of lanthanum. Twenty-four patients who revealed the histology of lanthanum deposition on gastroduodenal biopsy between 2011 and 2014 were included in the study, and their clinical records and gastroduodenal biopsies obtained from 2011 to 2015 were reviewed, adding the review of gastroduodenal biopsies before 2011 if possible.

    Small lymphocytic lymphoma/chronic lymphocytic leukemia (CLL/SLL) and mantle cell lymphoma (MCL) usually are distinctly different in regard to clinical presentation, morphology, immunophenotype and molecular/genetic findings. In spite of this, select cases may show overlapping characteristics and represent a diagnostic challenge. Recently LEF1 staining was identified as a fairly characteristic finding in CLL/SLL, with positivity identified in up to 95% of cases. Read More

    Heat shock proteins HSP90, HSP70 and GRP78 expression in medullary thyroid carcinoma.

    The chromatin remodeling switch sucrose nonfermentable (SWI/SNF) complex has been increasingly implicated in the pathogenesis and dedifferentiation of neoplasms from several organs with prognostic and potential therapeutic implications. We herein investigated the expression of the SWI/SNF complex catalytic subunits SMARCA4 (BRG1) and SMARCA2 (BRM) in 316 consecutive non-small cell lung cancer (NSCLC) specimens on tissue microarrays (171 adenocarcinomas [ADCAs], 130 squamous cell carcinomas [SCCs], 9 adenosquamous carcinomas, and 6 large cell carcinomas) excluding undifferentiated/giant cell or rhabdoid carcinomas. Complete loss of SMARCA4 was observed in 8 (5. Read More

    Differentiated squamous intraepithelial lesion (dSIL)-like changes in the epidermis overlying anogenital melanocytic nevi: A diagnostic pitfall.
    Ann Diagn Pathol 2017 Feb 14;26:43-46. Epub 2016 Nov 14.
    Department of Pathology, Charles University, Medical Faculty and Charles University Hospital Plzen, Czech Republic.
    Background: Differentiated squamous intraepithelial lesion (dSIL) is morphologically and immunohistochemically analogous in the whole anogenital region. dSIL is a premalignant lesion frequently misinterpreted histopathologically as a benign dermatosis. The authors describe a peculiar change in the basal cell layer of the epidermis/epithelium overlying anogenital melanocytic nevi that may histopathologically imitate dSIL. Read More

    Signet-ring cell lymphoma: clinicopathologic, immunohistochemical, and fluorescence in situ hybridization studies of 7 cases.
    Ann Diagn Pathol 2017 Feb 7;26:38-42. Epub 2016 Oct 7.
    Department of Pathology & Laboratory Medicine, Indiana University School of Medicine, Indianapolis, IN; Department of Medical and Molecular Genetics, Indiana University School of Medicine, Indianapolis, IN.
    Context: Signet-ring cell lymphoma (SRCL) is a rare morphologic variant of non-Hodgkin lymphoma. Although it was initially reported as a rare morphologic variant of follicular lymphoma (FL), SRCL has to date been described in most types of non-Hodgkin lymphoma, mostly as single-case reports.

    Objective: To study SRCL systematically by immunohistochemical stains and fluorescent in situ hybridization analyses. Read More

    Usefulness of p16/CDKN2A fluorescence in situ hybridization and BAP1 immunohistochemistry for the diagnosis of biphasic mesothelioma.

    Division of Pathology and Cell Therapy, Chiba Cancer Center Research Institute, Nitona 666-2, Chuo-ku, Chiba, Chiba 260-8717, Japan. Electronic address:
    Malignant mesothelioma is a highly aggressive neoplasm, and the histologic subtype is one of the most reliable prognostic factors. Some biphasic mesotheliomas are difficult to distinguish from epithelioid mesotheliomas with atypical fibrous stroma. The aim of this study was to analyze p16/CDKN2A deletions in mesotheliomas by fluorescence in situ hybridization (FISH) and BAP1 immunohistochemistry to evaluate their potential role in the diagnosis of biphasic mesothelioma.

    Cystic and necrotic papillary renal cell carcinoma: prognosis, morphology, immunohistochemical, and molecular-genetic profile of 10 cases.
    Ann Diagn Pathol 2017 Feb 20;26:23-30. Epub 2016 Oct 20.
    Department of Pathology, Charles University, Medical Faculty and Charles University Hospital Plzen, Czech Republic. Electronic address:
    Conflicting data have been published on the prognostic significance of tumor necrosis in papillary renal cell carcinoma (PRCC). Although the presence of necrosis is generally considered an adverse prognostic feature in PRCC, we report a cohort of 10 morphologically distinct cystic and extensively necrotic PRCC with favorable biological behavior. Ten cases of type 1 PRCC with a uniform morphologic pattern were selected from the 19 500 renal tumors, of which 1311 were PRCCs in our registry. Read More

    Hepatosplenic T-cell lymphoma arising in patients with immunodysregulatory disorders: a study of 7 patients who did not receive tumor necrosis factor-α inhibitor therapy and literature review.
    Ann Diagn Pathol 2017 Feb 18;26:16-22. Epub 2016 Oct 18.
    Department of Hematopathology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA. Electronic address:
    Hepatosplenic T-cell lymphoma (HSTCL) is a rare and aggressive extranodal T-cell lymphoma that can arise in patients with underlying immune disorders. Others have suggested that tumor necrosis factor (TNF)-α inhibitor therapy for immune disorders increases the risk of HSTCL. To assess for a potential relationship between HSTCL and the use of TNF-α inhibitors, we searched for patients with HSTCL and underlying immune disorders at our institution. Read More
