Background & Objective: Female breast cancer is one of the most prevalent malignancies among women. The critical step in managing breast cancer is to diagnose it accurately. Hence, peripheral blood-based tests are one of the most favorable and less invasive methods to study. Recent studies investigated and evaluated the inflammation parameters such as neutrophil: lymphocyte ratio (NLR), the platelet: lymphocyte ratio (PLR), and the C-reactive protein (CRP) levels. The elevation in mentioned parameters was proposed as a key factor in cancer progression. The main goal of this study was to investigate the association of NLR, PLR, and CRP levels in patients with breast lesions.Methods: The NLR, PLR, and CRP levels were calculated from 200 female patients with either benign or malignant lesions.Results: The cut-off values of NLR, PLR, and CRP were 1.24, 96, and 10.36 mg/L, respectively. A significant difference in NLR (P<0.001), PLR (P<0.001), and CRP levels (P<0.001) were observed between the two major studied cohorts.Conclusion: Elevated NLR, PLR, and CRP levels could predict the presence of malignancy. In addition to the low cost and properties of the mentioned methods, utilization of this data could facilitate and improve clinical decision-making for treatment.

Background & Objective: Multiple sclerosis (MS) is an inflammatory neurological disorder that affects the central nervous system (CNS) and causes individuals to experience a variety of cognitive and physical problems. As proven by two decades of clinical experience with immunomodulatory therapies for MS, the disease progresses and relapses through several immunological pathways. New medicines aimed at remyelination and neurodegeneration are being developed; however, they need stronger evidence before being introduced into routine clinical care. The purpose of this study was a thorough assessment of MS immunopathology and predictive biomarkers.
Methods: Immunotherapy, immunopathogenesis, and prognostic biomarkers were all parts of the search method. Only publications in English were considered for inclusion in the study. For that purpose, we went through the current state of knowledge around MS immunopathology and related biomarkers. Immunology, as well as the identification of increased inflammation as an important component of neurodegeneration, shaped our understanding of this disease aetiology. The relevant sources examined covered the years 2015-2021.
Conclusion: We found biomarkers in the cerebrospinal fluid and blood that might be used for the prediction and diagnosis of MS, as well as for measuring treatment response and adverse effects. Many variables, including the role of some infectious organisms and the impact of environmental and social factors, might contribute to the immunological dysfunctions seen in MS. Patients with MS may benefit from better therapy options if a better understanding of MS biomarkers and immune response mechanisms would be obtained.

Background and Objective: Xanthogranulomatous oophritis is an uncommon, non-neoplastic, chronic process in which the affected organ is destroyed by massive cellular infiltration of foamy histiocytes admixed with multinucleated giant cells, plasma cells, fibroblasts, neutrophils, and foci of necrosis. The etiology of this entity is unknown, but it shares histopathological findings similar to those of xanthogranulomatous change occurring in various organs, including the gallbladder and kidney.Case Report: The current case was a 20-year-old female presenting with a tubo-ovarian mass with suspicion of malignancy on clinicoradiological findings and final diagnosis of xanthogranulomatous oophritis established on histopathology.Conclusion: Clinically and radiologically, xanthogranulomatous oophritis mimics tumor of the ovary and fallopian tube, thereby making it an important entity. A vigilant histopathological evaluation is important to diagnose the disease.

Background & objective: Changes in submucosal vascularization and inflammation, determined by immunohistochemistry staining, were shown to be correlated with the development of dysplasia and invasiveness of epithelial cells in premalignant and malignant lesions. This study evaluated changes in sections routinely stained with Hematoxylin and Eosin (H&E) in order to investigate vascular density and intensity of inflammatory cells infiltration during the progression of oral leukoplakia with mild dysplasia to Squamous Cell Carcinoma (SCC).The aim of the research was to determine whether changes in sub-mucosal vascularity and inflammatory infiltration of leukoplakia in routine H&E-stained sections could contribute to the assessment of severity of the lesion. Methods: In this cross-sectional, comparative and descriptive study, vascular density and inflammation intensity of 125 available samples of H&E-stained sections, consisting of 35 cases of mild and moderate dysplasia, 38 severe dysplasia and carcinoma in situ, and 52 SCC, were investigated. To analyze the data, chi-square test, Mann-Whitney test, Kruskal-Wallis test, Tukey’s post hoc test, and cumulative ordinal logistic regression were conducted. Results: There was a significantly higher vascular density in cases with severe dysplasia, in situ carcinoma, and SCC compared to those with mild to moderate dysplasia (P<0.0001). However, the difference in vascularity was not statically significant between severe dysplasia, carcinoma in situ, and SCC (P=0.78). Intensity of inflammatory cells infiltration in the underlying connective tissue was significantly different among the three groups (P<0.0001), and the highest intensity of inflammatory cells infiltration was seen in the SCC group. Conclusions: Increased submucosal vascularization and inflammatory cells infiltration can contribute further to predicting more aggressive epithelial dysplasia.

Inflammatory myofibroblastic tumor is an uncommon benign neoplasm and its presentation in small bowel is rare. Due to clinical manifestation, laboratory data and radiologic results, there is an increased risk of over diagnosis as malignant tumors particularly malignant lymphoma in childhood therefore may be resulting in wrong therapeutic approach. However pathologic findings could be demonstrated definite diagnosis based on markedly proliferation of bland looking spindle cells which their presence can be confirmed by immunohistochemistry staining to show myofibroblastic differentiation. We describe here an unusual presentation of inflammatory myofibroblastic tumor of the terminal ileum in a 19-month-old girl who presented with anemia, eosinophilia, intestinal obstruction, focal ossification and dystrophic calcification within the tumor.
