#1
JOURNAL ARTICLE
Gulisa Turashvili, Krisztina Hanley
CONTEXT.—: Clinical management of endometrial carcinoma largely depends on the morphologic parameters ascertained based on the pathologic evaluation of surgical resection specimens. However, there are numerous controversial and nonstandardized aspects of both the macroscopic and microscopic assessment of surgical specimens, including grossing, adequate sampling, diagnosis, staging, reporting, and ancillary testing. OBJECTIVE.—: To provide a comprehensive practical review of standardized grossing, key morphologic findings for reporting and staging, and diagnostic and prognostic use of ancillary testing in endometrial carcinomas...

#2
JOURNAL ARTICLE
William R Borch, Sara E Monaco
CONTEXT.—: Workup of the poorly differentiated or undifferentiated tumor remains a significant and challenging entity in the practice of anatomic pathology. Particularly in the setting of small biopsies and limited material, these cases demand a balanced approach that considers the patient's clinical and radiologic presentation, a basic assessment of tumor morphology, a reasonably broad immunohistochemical panel, and diligent preservation of tissue for prognostic and therapeutic studies...

#3
JOURNAL ARTICLE
Siba El Hussein, Andrew G Evans, Hong Fang, Wei Wang, L Jeffrey Medeiros
CONTEXT.—: Unicentric Castleman disease (UCD) is a dynamic entity with a wide spectrum of morphologic findings. UCD can be further subdivided into hyaline-vascular and mixed/plasmacytic variants. Hyaline-vascular UCD has both follicular and interfollicular (stromal) changes, and occasionally these lesions show a skewed representation of either the follicular or stromal compartments. Plasmacytosis is usually minimal in hyaline-vascular variant. Mixed/plasmacytic variant of UCD is composed of sheets of plasma cells often associated with a variable number of follicles with regressive changes...

#5
JOURNAL ARTICLE
Joseph M Rohr, Kevin Ginnebaugh, Mark Tuthill, Jason Pimentel, Rodney Markin
CONTEXT.—: Intraoperative diagnosis by frozen section is a mainstay of surgical pathology practice, providing immediate feedback to the surgical team. Despite good accuracy with modern methods, access to intraoperative surgical pathology with an appropriate turnaround time (TAT) has been a limiting factor for small or remote surgical centers, with negative impacts on cost and patient care. Telepathology offers immediate expert anatomic pathology consultation to sites without an in-house or subspecialized pathologist...

JOURNAL ARTICLE
Gerald Webersinke, Jonathan Burghofer, Theodora Malli, Melanie Rammer, Stephan Wenzel Jahn, Axel Niendorf, Fattaneh A Tavassoli, Farid Moinfar
CONTEXT.—: Low-grade fibromatosis-like metaplastic carcinoma (FLMC) is a very rare subtype of triple-negative metaplastic (spindle cell) breast carcinoma. It is characterized by the proliferation of spindle cells closely resembling fibromatosis, which represents a benign fibroblastic/myofibroblastic breast proliferation. Unlike most triple-negative and basal-like breast cancers, FLMC has a very low potential for metastases, but demonstrates frequent local recurrences. OBJECTIVE...

#9
JOURNAL ARTICLE
Anne E Tebo, Lisa K Peterson, Melissa R Snyder, Dorota Lebiedz-Odrobina
CONTEXT.—: Antibodies to U1 ribonucleoprotein (U1RNP) were first described more than 50 years ago, and although clinically relevant for antinuclear antibody-associated connective tissue disease (ANA-CTD), test results are challenging to interpret. OBJECTIVE.—: To evaluate the impact of anti-U1RNP analyte diversity in the assessment of patients at risk for ANA-CTD. DESIGN.—: Two multiplex assays for U1RNP (Sm/RNP and RNP68/A) were used to test serum specimens from consecutive patients (n = 498) under evaluation for CTD in a single academic center...

#10
JOURNAL ARTICLE
Claudio Luchini, Aldo Scarpa
CONTEXT.—: Pancreatic neuroendocrine neoplasms (PanNENs) represent a heterogeneous group of epithelial tumors of the pancreas showing neuroendocrine differentiation. These neoplasms are classified into well-differentiated pancreatic neuroendocrine tumors (PanNETs), which include G1, G2, and G3 tumors, and poorly differentiated pancreatic neuroendocrine carcinomas (PanNECs), which are G3 by definition. This classification mirrors clinical, histologic, and behavioral differences and is also supported by robust molecular evidence...

#11
JOURNAL ARTICLE
Eric Erak, Thomas M Ulbright, Jonathan Epstein
CONTEXT.—: A recent study demonstrated that NKX3.1-positive staining can uncommonly be seen in testicular Sertoli cell tumors (1 of 4 cases). Also, it was reported that 2 of 3 Leydig cell tumors of the testis showed diffuse cytoplasmic staining for P501S, although it was unclear whether it was specific granular staining that defines true positivity. However, Sertoli cell tumors do not typically pose a diagnostic dilemma with metastatic prostate carcinoma to the testis. In contrast, malignant Leydig cell tumors, which are exceedingly rare, can closely resemble Gleason score 5 + 5 = 10 prostatic adenocarcinoma metastatic to the testis...
