Acute human papillomavirus (HPV) infection of the cervix (cervical intraepithelial neoplasia, CIN) is marked by high copy episomal viral DNA and L1/L2 capsid protein expression (productive infection) in the cells towards the surface that facilitate sexual viral transmission. Viral DNA is low copy and not associated with viral capsid protein expression in the less differentiated lower part of the CIN (nonproductive infection). The purpose of this study was to examine the host response in these two areas. Serial section and co-localization analyses demonstrated that in 29/33 (88%) of cases the NF-κB pathway was activated and localized to the suprabasal nonproductively infected cells in the CIN lesions...

BACKGROUND: Literature on non-neoplastic adrenal pseudocysts (NNAPC) remains limited and to date no large series have been reported. The pathogenesis of these lesions remains poorly defined, however a vascular origin is most often suggested in the literature. We aimed to evaluate the clinicopathological features and the spectrum of vascular changes within NNAPC, in order to better understand the mechanisms and circumstances of their pathogenesis. METHODS AND RESULTS: We reviewed 44 cases of surgically resected NNAPC...

Clear cell papillary renal cell carcinoma (ccpRCC) is a recently recognized subtype of renal cell carcinoma. In this study, we investigated the clinicopathological and immunohistochemical features in a group of 26 cases of ccpRCC, with a special emphasis on the expression of vitamin D receptor (VDR). The mean age of patients was 53.3 years (range 36-74 years), and the mean tumor size was 2.5 cm (range 0.5 to 6.5 cm). During follow-up (range 12-121 months, median 50 months), no recurrence or metastasis was observed...

Spinal cord paralysis is relatively common after surgical repair of thoraco-abdominal aortic aneurysm (TAAA) and its etiology is unknown. The present study was designed to examine the histopathology of the disease and investigate whether miR-155 ablation would reduce spinal cord ischemic damage and delayed hindlimb paralysis induced by aortic cross-clamping (ACC) in our mouse model. The loss of locomotor function in ACC-paralyzed mice correlated with the presence of extensive gray matter damage and central cord edema, with minimal white matter histopathology...

Tumor infiltrating lymphocytes (TILs) in breast cancer play an important role in predicting the outcome of breast cancer. The goal of our current study is to investigate the consistency and reproducibility of the recommendations published by the International TILs Working Group 2014 among pathology trainees and pathologists. Hematoxylin & Eosin (H&E) slides from 129 breast cancer cases (one slide each) from 2009 to 2014 were evaluated. Each case was blindly and independently reviewed by two observers following the International TILs Working Group 2014 recommendations...

BACKGROUND: Several prognostic indicators have been used for many decades in an attempt to predict clinical behaviour of Oral Squamous Cell Carcinoma (OSCC). The prognostic value of TSR is yet to be explored in OSCC. Hence, the aim of the present study was to evaluate the prognostic value of TSR in OSCC patients. METHODOLOGY: A cohort of 60 histologically diagnosed cases of OSCC who underwent Radical Neck Dissection was included in the study. TSR was assessed and patients with >50% intratumor stroma were quantified as the stroma-poor group and those with <50% as the stroma-rich group...

Fibro-osseous pseudotumors of the digits (FOPD) is a rare self-limiting lesion composed of bland looking hypercellular fibrous tissue and bone. USP6 rearrangement is a consistent genetic finding in aneurysmal bone cyst, nodular fasciitis, myositis ossificans and giant cell lesions of small bones. We report herein the occurrence of USP6 rearrangement in fibro-osseous pseudotumors of the digits using fluorescence in situ hybridization analysis (FISH). Of the five patients included, three were female and two were male...

The clinical decision to excise intraductal papilloma (IDP) without atypia diagnosed on biopsy remains controversial. We sought to establish clinical and histologic predictors (if any) which may predict upgrade in IDP. 296 biopsies (in 278 women) with histologic diagnosis of IDP without atypia were retrospectively identified and placed into Incidental (no corresponding imaging correlate), or Non-incidental (positive imaging correlate) groups. 253/296 (85.5%) cases were non-incidental, and 43/296 (14.5%) were incidental...

Serrated colorectal fibroblastic polyps (FPs) are rare benign mucosal lesions composed of serrated epithelial crypts separated and distorted by intimately associated bland spindle cell proliferations with perineurial-like phenotype. We herein describe 21 new FPs affecting 10 females and 9 males aged 45 to 80 yrs. (mean, 62 yrs). Lesions originated in the sigmoid colon/rectosigmoid junction (n = 16), rectum (n = 2), and other parts of the colon (n = 3). Most patients had additional synchronous or metachronous polyps: classical adenomas (12 patients), sessile serrated adenoma/SSA (1 patient), hyperplastic polyps/HPs (7 patients), both HPs and adenomas (6 patients) and colorectal cancer (2 patients)...

Desmoid-type fibromatosis, also called desmoid tumor, is a locally aggressive myofibroblastic neoplasm that usually arises in deep soft tissue with significant potential for local recurrence. It displays an unpredictable clinical course. β-Catenin, the genetic key player of desmoid tumors shows nuclear accumulation due to mutations that prevent its degradation leading to activation of Wnt signaling and myofibroblastic cell proliferation. The corresponding hot spot mutations are located in exon 3 of the CTNNB1 gene or alternatively, in the APC tumor suppressor gene, most often as a germline mutation...

BACKGROUND: Recently, we came with the theory of a possible relationship between a group of testicular and pancreatic tumors. We used one case of a pancreatic analogue solid pseudopapillary neoplasm of the testis composed partially of areas reminiscent of solid pseudopapillary neoplasm (SPN) of the pancreas and partially of structures identical to primary signet ring stromal tumor of the testis (PSRSTT) as a connecting link between these two entities. After demonstrating that PSRSTT and pancreatic analogue SPN of the testis share the same immunoprofile and genetic features characteristic for pancreatic SPN, we came to the conclusion that pancreatic analogue SPN of the testis and PSRSTT represent a morphological spectrum of a single entity and that both are related to the pancreatic SPN...

OBJECTIVES: Proteins p27 and c-Myc are both key players in the cell cycle. While p27, a tumor suppressor, inhibits progression from G1 to S phase, c-Myc, a proto-oncogene, plays a key role in cell cycle regulation and apoptosis. The objective of our study was to determine the association between expression of c-Myc and the loss of p27 by immunohistochemistry (IHC) in the four major subtypes of breast cancer (BC) (Luminal A, Luminal B, HER2, and Triple Negative) and with other clinicopathological factors in a population of 202 African-American (AA) women...

BACKGROUND: The mediator complex consists of 33 subunits and plays a central role in transcription. Studies have already described the involvement of individual subunits, especially in carcinogenesis. With regard to the subunit MED30, this has, so far, only been confirmed in gastric and breast carcinoma. The role of MED30 in urological tumours is unknown. MATERIALS AND METHODS: First, a database analysis using cBioPortal was performed for the mRNA expression and survival analysis of MED30 in clear cell renal cell carcinoma (ccRCC) and papillary RCC (pRCC)...

Pleomorphic adenoma (PA) of the submandibular gland is known to have a very low recurrence rate. The aim of this study was to investigate the histopathological and capsular characteristics of submandibular gland PA, looking for any differences between submandibular PA and the reported data for PA of the parotid gland as possible explanation for its low recurrence rate. We reviewed 72 submandibular gland PAs resected at our center between 2000 and 2016. Patient age ranged from 14 to 77 years (mean, 47.2). At least follow (range, 12 to 170 months; mean, 82), none of the 72 patients developed a local recurrence...

Solitary fibrous tumor (SFT) is a mesenchymal neoplasm that was originally described to be localized in the pleura, but thereafter, this has been reported in several anatomic sites. Although the etiology of the neoplasm remains largely unknown, the pathogenesis seems to be related to an NAB2-STAT6 fusion gene due to paracentric inversion on chromosome 12q13. The diagnosis of extrapleural SFT is challenging, owing to its rarity, and requires an integrated approach that includes specific clinical, histological, immunohistochemical, and even molecular findings...
