Bladder mucinous adenocarcinoma as a diagnostic challenge: a case report.

Primary bladder adenocarcinoma (PBA), especially the mucinous subtype, is a rare cancer that represents less than 2% of all bladder malignancies. Overlapping histopathological and immunohistochemical (IHC) features of PBA with metastatic colonic adenocarcinomas (MCA) make the final diagnosis very hard. We presented a 75-year-old woman presenting with hematuria and severe anaemia in the last two weeks.

Immunohistochemical Expression of Epidermal Growth Factor Receptor in Hepatocellular Carcinoma.

Introduction: Epidermal growth factor receptor (EGFR) signaling plays an important role in various cancers, including hepatocellular carcinoma (HCC). We aimed to evaluate immunoexpression of EGFR in HCC and surrounding non-tumor liver tissue and to correlate it to multiple clinicopathologic data.

Material And Methods: We analyzed 60 patients with HCC for multiple clinicopathologic characteristics and survival.

Thyroid cancer detection rate and associated risk factors in patients with thyroid nodules classified as Bethesda category III.

Background Ultrasound guided fine-needle aspiration (FNA) is a standard procedure for thyroid nodules management and selecting patients for surgical treatment. Atypia of undetermined significance (AUS) or follicular lesion of undetermined significance (FLUS), as stated by The Bethesda System for Reporting Thyroid Cytopathology, is a diagnostic category with an implied malignancy risk of 5-15%. The aim of our study was to review cytology and histopathology reports, as well as clinical and ultrasound data, for thyroid nodules reported as AUS/FLUS, in order to evaluate the malignancy rate and to assess factors associated with malignant outcome.

Endometrioid Adenocarcinoma Arising in Adenomyoma in a Woman with a Genital Prolapse - Case Report.

Background: Endometrial cancer is the third-ranked genital malignancy in women and includes 3% of cancer deaths. There is a 2.8% chance of a woman developing endometrial cancer during her lifetime.

Correlation of Immunohistochemistry and Fluorescence Hybridization for HER-2 Assessment in Breast Cancer Patients: Single Centre Experience.

Background: Accurate assessment of HER-2 is imperative in selecting patients for targeted therapy. Most commonly used test methods for HER-2 are immunohistochemistry (IHC) and fluorescence in situ hybridisation (FISH). We evaluated the concordance between FISH and IHC for HER-2 in breast cancer samples using Food and Drug Administration approved tests.

Factors That Influence Surgical Margin State in Patients Undergoing Cold Knife Conization - A Single Center Experience.

Aim: To evaluate the factors that influence the surgical margin state in patients undergoing cold knife conization at the University Clinic of Gynecology and Obstetrics in Skopje, Republic of Macedonia Materials and methods: We have retrospectively analyzed the medical records of all patients that underwent a cold knife conization at our Clinic in 2015.

[The possible pathogenesis of AA type amyloidosis in a patient with ulcerative colitis and renal cell carcinoma].

A 43-year-old male with a two-month history of ulcerative colitis and nephrectomy due to a renal cell carcinoma performed a month before was admitted to University Department of Nephrology for nephrotic syndrome and chronic renal failure. Biopsy of the remnant kidney revealed secondary AA amyloidosis with deposits in the glomeruli and walls of intrarenal blood vessels. Re-evaluation of the nephrectomized kidney also showed amyloid deposits both in the renal tissue free from malignant cells and in tumor tissue.

Histomorphometric analysis of fibrosis in the renal interstitial compartment.

The interstitium is the extravascular intertubular space of the renal parenchyma, which provides structural support to the functional renal units and is included at the same time in nearly all renal functions. Alterations to this renal compartment have been found in almost all glomerular diseases. During the last thirty years the studies of a few groups of investigators have shown that the degree of the renal dysfunction is strongly correlated with the changes in the tubulointerstitial compartment.
