The number of nephrons is a multifactorial trait controlled by the interaction of environmental factors and genetic variants that influence the extent of branching nephrogenesis during foetal life. A correlation between renal mass and nephron number in newborns allows the use of the total kidney volume at birth as a surrogate for congenital nephron number.(More)
The aim of this study was to evaluate associations between seven morphometric parameters of the nucleoli and nuclei of methyl green and pyronin Y (MG-PY) stained tumour cells of invasive ductal breast carcinoma with relapse-free survival (RFS) and overall survival (OS) time. Histological sections from 150 invasive ductal breast cancers were stained with(More)
Thyroid metastases account for approximately 1.4-3% of all malignancies of the thyroid gland. Thyroid metastases are most common in: clarocellular carcinoma of the kidney, lung cancer, breast cancer, malignant melanoma and cancers of gastrointestinal tract. A rare situation is when thyroid metastasis is diagnosed before detecting primary malignant focus and(More)
The article presents a case of 57-year-old woman with the infiltration of rare small lymphocytic B cell lymphoma in the thyroid gland. Initially, the patient was followed-up due to chronic lymphocytic B-cell leukemia diagnosed on the basis of histopathological examination of cervical lymph node. Eight months later, general symptoms occurred along with(More)
Gastric hyperplastic polyps (GHP) constitute up to 93% of all benign epithelial polyps of the stomach. The average probability of malignant transformation in GHP is 0.6-22% in large series. The aim of the study was to present the coexistence of GHP with early gastric cancer (EGC), gastric adenoma (GA), neuroendocrine cell hyperplasia (NH) and(More)
OBJECTIVE Early gastric cancer (EGC) is defined as cancer invasion confined to the mucosa or submucosa, irrespective of lymph node metastasis. Recently endoscopic submucosal dissection (ESD) has been widely accepted for the treatment for dysplasia and EGC without lymph node metastases. While the method has been advanced in Far East countries, ESD is still(More)
Rhinoscleroma is a chronic inflammatory disease in which granulation tissue with a typical cell content is found. The paper presents the case of a 77-year-old woman with clinically diagnosed nodule in the nasal cavity. The histopathological examination revealed granulation tissue with plasma cells and Mikulicz's cells. The clinical and morphological picture(More)
The aim of this study was to assess the: 1) clinicopathologic features of papillary early gastric cancer (PEGC) (13 cases) compared to tubular early gastric cancer (TEGC) (41 cases); 2) efficiency of endoscopic submucosal dissection (ESD) in treatment of PEGC. From January 2007 to February 2016, a total of 54 consecutive patients with early gastric cancer(More)
The correlation of thymidylate synthase (TS) expression in gastric cancers with tumor histology and prognostic or predictive information remains unclear. Most studies have involved Asian populations, with few conducted in European cohorts. Moreover, all published studies analyze TS expression using semi-quantitative methods. This retrospective study(More)
AIM To determine the prevalence and characteristics of additional primary malignancies in gastric cancer (GC) patients. METHODS GC patients (862 total; 570 men, 292 women; mean age 59.8 ± 12.8 years) diagnosed at the Department of Gastroenterology at Pomeranian Medical University over a period of 23 years were included in this retrospective analysis of a(More)
