Autoimmune metaplastic atrophic gastritis (AMAG) is an underrecognized entity, especially in its early stage. This study assessed whether the use of gastrin immunohistochemistry would increase sensitivity for diagnosing early AMAG. Three-hundred gastric biopsies were prospectively stained for gastrin by immunohistochemistry. Inclusion criteria incl...

This study aimed to determine whether Ki-67 index evaluated on cytologic material could reliably grade pancreatic neuroendocrine tumors (PanNETs). Cases with adequate cell block and available surgical specimens were included. Ki-67 index was calculated using "eyeballing," "hot spot," and "complete" counting methods. The overall concordance rates be...

Vacuum-assisted biopsy (VAB) of the breast seems unsuitable for rapid processing due to large size. We tested microwave-based acceleration. As a proof-of-principle study, 9-gauge VAB specimens were taken from eight mastectomy specimens. Forty-two biopsy specimens were processed. Quality of H&E was evaluated in 84 slides, and estrogen receptor (ER),...

To assess the diagnostic accuracy of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in acute inflammation. PubMed and Scopus were searched and eligible articles were screened for methodologic quality using the Quality Assessment of the Diagnostic Accuracy Studies-Revised. Meta-analysis with calculation of pooled sensitivity (Se),...

High-grade prostatic intraepithelial neoplasia (HPIN) and atypical cribriform lesion of the prostate are considered the precursors or associators of invasive prostate cancer (iPCa). Given loss of basal cells being the hallmark of iPCa, we hypothesized that a subset of these atypical intraepithelial lesions (AILs) with sparse basal cells can be clas...

Diagnosis of metastatic basal cell carcinoma (BCC) remains challenging, in part due to its rarity. With the advent of molecularly targeted therapies, recognition of this entity is more important than ever. We identified 11 cases of metastatic BCC over a 13-year period. We analyzed these tumors in conjunction with their respective primary tumors by ...

Pathogenic free-living amebae (FLAs) cause skin, ocular, and central nervous system (CNS) infections with significant morbidity and mortality. Diagnosis of FLA infections by pathologic examination of tissue sections can be aided using molecular assays. This study investigated the performance characteristics of a multiplex real-time polymerase chain...

Early diagnosis of tuberculosis (TB) and multidrug-resistant TB (MDR-TB) is a priority for Viet Nam's National TB Control Programme. In many laboratories, quality systems are weak; few have attained accreditation. We implemented a structured training and mentoring program for TB laboratories and measured impact on quality. Six TB culture laboratori...

Laryngeal neuroendocrine carcinomas are heterogeneous neoplasms characterized by neuroendocrine differentiation. Their prognoses are dependent on tumor type, therefore different classifications have been developed. Moreover, other tumors have overlapping pathologic features posing a range of diagnostic possibilities. A review of the literature was ...
