The Usefulness of Elastin Staining to Detect Vascular Invasion in Cancer.

Tumor prognosis hinges on accurate cancer staging, a pivotal process influenced by the identification of lymphovascular invasion (LVI), i.e., blood vessel and lymphatic vessel invasion.

Brenner Tumor of the Ovary: A 10-Year Single Institution Experience and Comprehensive Review of the Literature.

Brenner tumors (BTs) are surface-epithelial stromal cell tumors that are categorized by the World Health Organization as benign, borderline, and malignant. Due to the rarity of BTs, the published literature on these tumors is comprised primarily of case reports and small retrospective studies. We performed a pathology database review spanning the last ten years at our institution revealing nine reported benign BTs.

Diffuse pulmonary ossification: A case report unveiling clinical and histopathological challenges.

Diffuse pulmonary ossification (DPO) is a rare pulmonary condition characterized by the diffuse formation of mature bone in the lungs. Pulmonary ossification, in general, can be subdivided into diffuse pulmonary ossification (DPO) and nodular pulmonary ossification (NPO). DPO occurs most commonly in the settings of chronic pulmonary conditions; however, idiopathic cases have been reported.

Drug Repurposing in Non-Small Cell Lung Carcinoma: Old Solutions for New Problems.

Lung cancer is the second most common cancer and the leading cause of cancer-related deaths in 2022. The majority (80%) of lung cancer cases belong to the non-small cell lung carcinoma (NSCLC) subtype. Despite the increased screening efforts, the median five-year survival of metastatic NSCLC remains low at approximately 3%.

Neonatal acute liver failure with pulmonary yellow hyaline membrane and kernicterus.

Background: Neonatal acute liver failure (NALF) is a rare and life-threatening condition. It causes bilirubin to accumulate to a dangerous level in the body, causing permanent damage to vital organs such as the brain and lungs. In many cases, the etiology of NALF remains unknown.

Correlation between spread through air spaces (STAS) and other clinicopathological parameters in lung cancer.

Background: "Spread through airspace" (STAS) is defined as micropapillary clusters, solid nests or single cells of tumor extending beyond the edge of the tumor into the air spaces of the surrounding lung parenchyma. It is associated with reduced overall survival and disease-free survival. Assessment of STAS in lung cancer appears to be necessary to guide clinical interventions.

Objectives: to evaluate maternal and child healthcare, avoidable hospitalisation, access to emergency services among immigrants in Italy.

Design: cross sectional study of some health and health care indicators among Italian and foreign population residing in Italy in 2016-2017.

Setting And Participants: indicators based on the national monitoring system coordinated by the Italian National Institute for Health, Migration and Poverty (INMP) of Rome, calculated on perinatal care (CedAP), hospital discharge (SDO), emergency services (EMUR) archives for the years 2016-2017, by of the following regions: Piedmont, Trento, Bolzano, Emilia-Romagna, Tuscany, Umbria, Lazio, Basilicata, Sicily.

Low-Grade Ductal Carcinoma In Situ.

Objectives: We aimed to determine the interobserver reproducibility in diagnosing low-grade ductal carcinoma in situ (DCIS). We also aimed to compare the interobserver variability using a proposed two-tiered grading system as opposed to the current three-tiered system.

Methods: Three expert breast pathologists and one junior pathologist identified low-grade DCIS from a set of 300 DCIS slides.

IMP3 expression in serous tumors of the ovary.

Insulin-like growth factor II mRNA-binding protein (IMP3) is an oncofetal protein involved in embryogenesis, which is expressed in a variety of malignant neoplasms. It is rarely expressed in normal adult tissue and benign tumors. The aim of this study was to evaluate the expression of IMP3 in benign and malignant serous tumors of the ovary.

Identifying professional education gaps and barriers in multiple myeloma patient care: findings of the Managing Myeloma Continuing Educational Initiative Advisory Committee.

Advances in the past decade and a half have led to unprecedented improved outcomes for patients with multiple myeloma (MM), and this disease appears to be transitioning to one more characteristic of a chronic disease in large part due to rapid translation of clinical insights into practice at the community level. Although evidence-based guidelines and consensus recommendations remain an important resource for managing cancer patients, they do not fill the gap between the principles of disease management today and the translation of tailoring treatment for individual patient needs. Thus, there is a continuing need for concise, focused educational activities and resources that facilitate improved knowledge and understanding of appropriate, individualized therapeutic strategies for assessing and caring for patients with MM.

Cutaneous Metastases from Urothelial Carcinoma of the Bladder: A Rare Presentation and Literature Review.

With the advances in imaging, earlier detection of recurrence and metastatic disease is possible. However, there are limited data on the metastatic pattern of bladder cancer. In addition, cutaneous metastases from primary genitourinary malignancies are rare and, in spite of advances in imaging, which detect smaller lesions, the patterns of metastases from bladder cancer have not been well described.

Serous carcinoma of the ovary and peritoneum with metastases to the breast and axillary lymph nodes: a potential pitfall.

Metastasis of ovarian or peritoneal serous carcinoma to the breast and/or axillary lymph nodes is a rare event. Nevertheless, its recognition and distinction from mammary carcinoma are of great clinical importance because the treatment and prognosis differ significantly. Eighteen cases of ovarian or peritoneal serous carcinoma metastatic to the breast and/or axillary LNs from a 14-year period (1990-2003) were retrieved from our files.

Fine-needle aspiration cytology of mucinous tumors of the pancreas.

Background: Tumors of the pancreas associated with extracellular mucin production include mucin-producing ductal adenocarcinoma, mucinous cystic neoplasm (MCN), and intraductal papillary mucinous tumor (IPMT). Fine-needle aspiration (FNA) is used as an adjunct to radiologic analysis for the preoperative categorization of these tumors. The current study was designed to identify distinctive cytomorphologic features that would be useful for the categorization of mucinous tumors of the pancreas.

Tubular carcinoma of the breast: an institutional experience and review of the literature.

Tubular carcinoma of the breast is a variant of invasive ductal carcinoma that is well differentiated and characterized by an orderly tubular formation. Although often perceived to have a better prognosis, there continues to be questions regarding the extent of treatment required. A retrospective review of 44 patients diagnosed with tubular carcinoma of the breast from 1987 to 1999 was performed.

Large-needle core biopsy in atypical intraductal epithelial hyperplasia including immunohistochemical expression of high molecular weight cytokeratin: analysis of results of a single institution.

The diagnosis of atypical intraductal epithelial hyperplasia (AIDH) constitutes 6.3% of the breast core biopsies performed at our institution. Seventy-nine cases that were diagnosed as AIDH on core biopsy and went through excisional biopsy were included.

Precursor B-cell lymphoblastic lymphoma/leukemia presenting as osteoblastic bone lesions.

Lymphoblastic lymphoma is a neoplasm of precursors lymphoid cells morphologically indistinguishable from those of acute lymphoblastic leukemia. Approximately 10% to 20% of cases are of the precursor B-cell (P-BLL) phenotype. This type of lymphoma most often manifests in the skin and lymph nodes.

Extranodal lymphoplasmacytoid lymphoma (immunocytoma) presenting as small intestinal obstruction.

A 57-year-old woman presented with intermittent symptoms of intestinal obstruction. Workup provided nondiagnostic radiologic studies. An exploratory laparotomy revealed a segmental dilatation in the proximal ileum, which showed diffuse thickening of the intestinal wall.

Chordoid glioma: a novel tumor of the third ventricle.

Chordoid glioma of the third ventricle is a recently characterized primary neoplasm of the central nervous system. We present a case and discuss the pathologic and radiologic features. We are aware of only 16 other cases documented in the world literature.

Triorganotin compounds as antimicrobial agents.

Six triorganotin derivatives of thiolupinine(1-mercaptolupinane), 2-mercaptobenzoxazole and 2-mercaptobenzothiazole were prepared and tested against several bacteria, fungi and protozoa. Most compounds exhibited high activity against the tested microorganisms and particularly worth noting was the activity of triethyltin lupinylsulfide on Gram-negative strains. Triethylgermanium lupinylsulfide was also prepared but was devoid of action on the whole set of tested microorganisms.

Gold(I) complexes as antimicrobial agents.

Seven gold complexes were prepared and investigated for biocidal activity against Gram-positive and -negative bacteria, fungi and protozoa. All of them were active against the tested microorganisms with the exception of Pseudomonas aeruginosa. In many, cases minimum inhibitory concentrations (MIC) were well below 1 microgram/ml.
