Objectives: To demonstrate how the educational presentation and targeted review of cases with discrepant interpretive findings between pathologists can raise awareness for specific diagnostic errors through identification of common overarching patterns of error in interpretive pathology.

Methods: We performed a review of 147 surgical pathology and cytopathology cases of discordances from 23 PowerPoint presentations presented between 2010 and 2017. Pathologists and pathology residents, blinded from the official interpretations, were presented each case and surveyed for their own diagnostic assessments.

The Deleted in liver cancer one (Dlc1) tumor suppressor gene encodes a RhoGTPase activating protein (RhoGAP). The Dlc1 gene has multiple transcriptional isoforms and we have previously established a mouse strain containing a gene trap (gt) insertion, which specifically reduces the expression of the 6.1 kb isoform (isoform 2).

We undertook this study to assess the characteristics of smears with features intermediate between high-grade squamous intraepithelial lesion (HSIL) and low-grade squamous intraepithelial lesion (ISIL). We also wanted to determine how these smears correlate with high risk biopsy diagnosis and to compare this with the biopsy correlation of LSIL and HSIL. Seventy-four squamous intraepithelial lesion (SIL) smears were identified as intermediate-grade SIL smears taken at colposcopy in a 1 year period.

Objective: To determine whether or not concurrent core biopsy adds to results obtained from image-guided fine needle aspiration biopsy (FNAB) in cases of lymphoma.

Study Design: Twenty-eight FNABs of lymphomas with adjuvant flow cytometry (FC) and concurrent core biopsy were evaluated retrospectively. In each case, completeness of diagnosis by FNAB, including phenotyping and grading, where appropriate, was reviewed.

Objective: To determine the accuracy of fine needle aspiration biopsy in establishing the primary on cytology and on cytologic and electron microscopy examinations using tissue biopsy as the gold standard.

Study Design: A retrospective study of 96 nonrandomly selected cases of metastases with an unknown primary was carried out. Tissue biopsy was performed subsequently for confirmation.
