Jordan M Gales, Lara Jehi, Amy Nowacki, Richard A Prayson
Hippocampal sclerosis (HS) and focal cortical dysplasia (FCD) are among the most common neuropathological findings in those undergoing surgery for refractory mesial temporal lobe epilepsy (MTLE). Existing data regarding differences among the most recent International League Against Epilepsy (ILAE) HS subtypes remains limited. This study sought to characterize the roles of HS subtype and coexistent FCD. Epilepsy surgery pathologic specimens in 307 cases of temporal lobe epilepsy with HS were reviewed (mean age ± SD, 37 ± 15 years, 56% women)...

GATA binding protein-3 (GATA3) is a transcription factor that regulates cell differentiation and maintenance in some types of normal cells. This study aimed to investigate the association between GATA3 expression and primary lung adenocarcinoma and to clarify the clinical significance of GATA3 expression in lung adenocarcinoma. Immunohistochemical GATA3 expression was evaluated using completely resected lung adenocarcinoma samples from 95 cases. GATA3 immunohistochemical staining was performed and scored. Associations between clinicopathological factors and GATA3 expression were analyzed by using the χ(2)-test and Fisher's exact test...

An unusual case of a polypoid, malignant gastric tumor in a 62-year man is presented. Endoscopy and subsequent polypectomy revealed an 8.5 x 6.5 x 4.5cm lesion in the body of the stomach. Microscopy showed surface dysplasia with an invasive adenocarcinoma displaying prominent tubulopapillary areas composed of large vacuolated cells, pleomorphic nuclei and occasional cytoplasmic hyaline globules. This component then blended with tubular structures lined by more primitive appearing vacuolated cells embedded within a stroma made up of cellular primitive, high-grade blastema-like areas and, less cellular more pleomorphic foci with spindle and several bizarre, large cells...

Given the current rapid expansion of biological knowledge and the challenges of translating that knowledge into clinical practice, finding effective methods of teaching graduate students clinical medicine concepts has become even more critical. The utility of autopsy in medical student and resident education has been well-established. Multiple studies have reported it to be a helpful means of teaching anatomy, pathophysiology, clinical problem-solving skills, and medical diagnostic techniques. While various models of training Ph...

Prostatic carcinoma, like many other carcinomas, generates a stromal reaction. This phenomenon is well established in the scientific literature. The normal parenchymal smooth muscle phenotype switches to a myofibroblastic phenotype in response to the presence of cancer cells, with an expansion of the extracellular matrix compartment. The amount of reactive stroma is a predictor of biochemical recurrence in both radical prostatectomies and biopsies. It is a predictor of prostate cancer specific death in prostatectomies...

Heterotopic ossification (HO, also termed myositis ossificans) is the formation of extra-skeletal bone in muscle and soft tissues. HO is a tissue repair process gone awry, and is a common complication of surgery and traumatic injury. Medical strategies to prevent and treat HO fall well short of addressing the clinical need. Better characterization of the tissues supporting HO is critical to identifying therapies directed against this common and sometimes devastating condition. The physiologic processes of osteogenesis and angiogenesis are highly coupled and interdependent...

The c-Jun dimerization protein 2 (JDP2) belongs to the activator protein-1 (AP-1) family and functions as a repressor of the AP-1 complex by dimerizing with other c-Jun proteins. Thus, JDP2 plays an important role in the repression of AP-1-driven biological processes, such as differentiation and proliferation. Recent studies have suggested that JDP2 may function as a tumor suppressor through its suppressive action against the AP-1 complex, which is known to drive oncogenic signals in several human malignancies...

Renal oncocytoma and chromophobe renal cell carcinoma (RCC) have been long recognized as distinct tumors; however, it remains unknown if uniform diagnostic criteria are used to distinguish these tumor types in practice. A survey was distributed to urologic pathologists regarding oncocytic tumors. Responses were received from 17/26 invitees. Histologically, >1 mitotic figure was regarded as most worrisome (n=10) or incompatible (n=6) with oncocytoma diagnosis. Interpretation of focal nuclear wrinkling, focal perinuclear clearing, and multinucleation depended on extent and did not necessarily exclude oncocytoma if minor...

Ectopic meningothelial proliferations are rare and can occur in a multitude of extracranial/spinal anatomic locations. Perineurioma is another uncommon entity that shares similar histological characteristics to those found in meningothelial proliferations. These include bland spindle cells with thin, bipolar nuclei, eosinophilic cytoplasm, and indistinct cell borders, arranged in short fascicles with whorl formation. Given their uncommon occurrence and shared histological and immunohistochemical features, their distinction can present a diagnostic challenge...

Xp11 translocation renal cell carcinoma (RCC) with SFPQ/PSF-TFE3 gene fusion is a rare epithelial tumor. Of note, the appearance of the gene fusion does not necessarily mean that it is renal cell carcinoma. The corresponding mesenchymal neoplasms, including Xp11 neoplasm with melanocytic differentiation, TFE3 rearrangement-associated perivascular epithelioid cell tumor (PEComa) and melanotic Xp11 translocation renal cancer, can also harbor the identical gene fusion. However, the differences between Xp11 translocation RCC and the corresponding mesenchymal neoplasm have only recently been described...

In normal colonic epithelium, the proliferative zone is limited to the lower half of the colonic crypt. Evaluating the changes in the colonic epithelial proliferation can be useful in understanding pathophysiology of various diseases. Our aim was to investigate the proliferative compartment of serrated polyps (SPs) using MCM2, a protein involved in DNA replication, and assess for changes along the SP spectrum. Immunohistochemistry was performed on serrated polyps (16 microvesicular-type hyperplastic polyps (HP), 58 sessile serrated adenomas (SSA), seven SSAs with dysplasia) and six sections of normal colon using anti-MCM2 antibody...

Detection of active human papillomavirus (HPV) is clinically important, as its presence has been shown to correlate with favorable clinical outcomes and better response to treatment in oropharyngeal squamous cell carcinomas (SCC). Using a clinical automated platform, we compared the performance of commercially available HPV DNA and RNA in situ hybridization (ISH) probes in archival tissues of 57 SCC. Importantly, a clinical automated platform gives 1) consistent and reproducible results for HPV ISH and 2) better standardization across clinical laboratories...

Phospho-Akt (P-Akt1) promotes proliferation and increased survival in vitro and plays an important role in prostate cancer (PCa) progression as well as the prediction of the probability of recurrence. In this study, the goal was to demonstrate the involvement and impact of P-Akt1 on cellular interactions, biomechanisms and pathways in PCa. Tissue microarrays from 640 PCa patients were immunostained with various antibodies. Ki67 was used to measure proliferation index and Tunnel for apoptotic index. Increased expression of P-Akt1 was associated with an increased proliferation, but inversely correlated with apoptotic index...

Prostaglandin E 2 (PGE2), which is the most abundant prostaglandin produced in hepatocellular carcinoma (HCC), may be involved in hepatocarcinogenesis. Here, the amount of PGE2 was significantly increased in HCC tissue and adjacent non-cancerous tissues relative to normal liver tissue (P<.001). In addition, the expression of EP2 receptor was considerably up-regulated in HCC tissue compared with the expression of EP1 (P<.05), EP3 (P<.01), and EP4 (P<.01) receptor. The expression of EP2 receptor was positively correlated with the level of PGE2 in HCC tissue (P<...

Spasmolytic polypeptide-expressing metaplasia (SPEM) and intestinal metaplasia (IM) have been recognized as neoplastic precursors in gastric carcinogenesis. We explored the relationship between SPEM and IM in Epstein-Barr virus-associated (EBVaGC) and Epstein-Barr virus-negative (EBVnGC) gastric cancer. 64 EBVaGC and 154 EBVnGC patients were included. EBV-positivity was identified using EBER-1 in situ hybridization. SPEM was sub-classified into absent, early and advanced SPEM. Acute and chronic inflammation was graded as absent, mild, moderate and marked...

In this study the histologic grade of dedifferentiated liposarcomas was correlated with outcome in surgically resected specimens in 55 patients over a 19-year period at the University of Pittsburgh Medical Center. The tumors were located in the retroperitoneum (N=34); the extremities and thigh (N=16), and the remainder involved the spermatic cord and head and neck. Most tumors were large (mean=21 cm.) Follow up was available in all 55 patients (median=36months). Forty-one tumors classified as high-grade dedifferentiated liposarcoma (HG-DDLPS) had mitotically active pleomorphic and spindle cells and foci of necrosis...

Usual interstitial pneumonia (UIP) is characterized by progressive scarring of the lungs and is associated with high morbidity and mortality despite therapeutic interventions. Sex steroid receptors have been demonstrated to play an important role in chronic lung conditions; however, their significance is unknown in patients with UIP. We retrospectively reviewed 40 idiopathic UIP cases for the expression of hormonal receptors. Forty cases including 10 normal lung, 10 cryptogenic organizing pneumonia (COP), 10 idiopathic organizing diffuse alveolar damage (DAD), 7 hypersensitivity pneumonitis (HP) and 3 nonspecific interstitial pneumonitis (NSIP) served as controls...

Salivary gland carcinomas (SGCs) exhibit heterogeneous biological behaviors, including the formation of distant metastases, which is a critical event associated with poor prognosis. Ezrin, which is a member of the ezrin-radixin-moesin family of plasma membrane-cytoskeleton linker proteins, may provide a marker for metastasis and poor survival of patients with cancer. The aim of the present study was to investigate the relationship between ezrin expression and the expression of HER2, p53, and Ki-67 as well as clinicopathological factors in SGCs...

Doxycycline induced gastric injury is a rarely recognized side effect of a common medication. Only two cases have previously described the distinctive capillary degeneration identified in gastric mucosa. We expanded on this by describing additional involved sites, endoscopic findings and patient characteristics. Design Gastrointestinal biopsy materials for cases indexed with the word "doxycycline" were retrieved and the histology reviewed. The medical record was used to obtain clinical details. Three cases with biopsy materials were identified from the search and doxycycline ingestion was confirmed...

Intratumor heterogeneity (ITH) is increasingly being recognized as a highly complex process with high clinical impact that deserves special attention from practicing pathologists. The value of the ITH detection depends on the correctness of the pathologist's sampling. The goal of this review is twofold. On the one hand, we provide a basic scientific context for the practical pathologist's perspective. On the other, we encourage pathologists to adopt a more scientific and up-to-date approach to a key component of their daily work, namely, how to sample a tumor for reliable histological and molecular analysis...
