Abstract
BACKGROUND Follicular dendritic cell sarcoma (FDCS) is a rare low-grade tumor of the lymph nodes, but roughly one-third of the cases emerge from extranodal sites, posing diagnostic challenges. CASE PRESENTATION In this report, we present the case of a 59-year-old lady who complained of renal colic. During investigation, a kidney tumor was discovered. A radical nephrectomy was performed, and histological examination identified the tumor as a sarcomatoid renal cell carcinoma. The case was then referred to a genitourinary pathologist for further evaluation. The tumor cells exhibited positive staining for CD21, CD23, somatostatin receptor 2 A, and MDM2 expression. Additionally, MDM2 gene amplification was confirmed by the FISH study. Ultimately, the tumor was diagnosed as a primary renal FDCS. The patient was placed under active oncological surveillance and did not receive any further therapy. Remarkably, after 91 months of follow-up, she remains tumor-free. CONCLUSION This case represents a well-documented primary renal FDCS. Our aim in presenting this extremely rare tumor is to enhance awareness and highlight the importance of considering FDCS in the differential diagnosis.

Abstract
INTRODUCTION End-stage renal disease (ESRD) and acquired cystic kidney disease (ACKD) are known risk factors for renal cell carcinoma (RCC). Hereby, the clinicopathological features of RCCs developed in ESRD were investigated. METHODS A database consisting of 34 tumors from 31 patients with ESRD among 2,566 nephrectomy samples of RCC was built. The demographic, clinical, and follow-up data along with pathological parameters were analyzed. The RCCs were diagnosed according to the current WHO Classification of Urinary and Male Genital Tumors. RESULTS Twenty-two tumors developed in men and 12 in women, with a median age of 56 years (range: 27-75 years). The causes of ESRD were glomerulonephritis (n = 7), hypertensive kidney disease (n = 6), autosomal dominant polycystic kidney disease (n = 6), chronic pyelonephritis (n = 4), diabetic nephropathy (n = 3), chemotherapy-induced nephropathy (n = 1), and undetermined (n = 4). ACKD complicated ESRD in 12 patients. The following histological subtypes were identified: clear cell RCC (n = 19), papillary RCC (n = 5), clear cell papillary tumor (n = 5), ACKD RCC (n = 3), and eosinophilic solid and cystic RCC (n = 2). The median tumor size was 31 mm (range: 10-80 mm), and 32 tumors were confined to the kidney (pT1-pT2). There was no tumor-specific death during the period of this study. Progression was registered in 1 patient. CONCLUSION In our cohort, the most common RCC subtype was clear cell RCC (55%), with a frequency that exceeded international data appreciably (14-25%). The incidence of clear cell papillary tumor and ACKD RCC (14.7% and 8.5%) was lower than data reported in the literature (30% and 40%). Our results indicate a favorable prognosis of RCC in ESRD.

Abstract
We report the case of a 50-year-old woman with severe erythrocytosis and uterine leiomyoma. The suspicion of myomatous erythrocytosis syndrome was supported by erythropoietin level higher than expected. After the supravaginal hysterectomy, the patient's red cell parameters normalized and the erythropoietin level markedly decreased. The authors are discussing the physiology of uterine erythropoietin, the evaluation and differential diagnostic value of erythropoietin investigations. Orv Hetil. 2022; 163(52): 2088-2092.

Abstract
PURPOSE Cystic echinococcosis (CE) is a parasitic disease caused by the tapeworm Echinococcus granulosus sensu lato. Although in Hungary the disease is listed among reportable infections, inadequacies in the reporting practice of CE by clinicians and pathologists have resulted in underscoring of this disease. The aim of this study was to describe the epidemiological and clinical characteristics of CE in Hungary using a datasource other than the official records that are based mainly on serological data. METHODS AND RESULTS This retrospective case series study included a total of 45 CE patients confirmed by histopathology in a single Hungarian center between 2000 and 2014. CONCLUSION Although CE is the most prevalent reportable endemic helminthosis in Hungary, to date this is the first study on the clinical epidemiology of the disease in this country.

Abstract
We report a case of a patient with triple synchronous primary malignancies (breast, colon, kidney) which has not been previously reported in the literature. A 70-year-old woman was diagnosed with invasive ductal carcinoma of the left breast with axillary lymph node metastasis. During the staging period, renal cell carcinoma on the left kidney and mucinous adenocarcinoma in the proximal colon were found. Since the breast tumour demonstrated favourable biology, aromatase inhibitor therapy had been started and simultaneous right colectomy and left nephrectomy was performed. Six months after the first diagnosis, left sector excision and axillary block dissection were performed. Adjuvant FEC chemotherapy was administered, followed by radiotherapy. During the 16-month follow-up period disease recurrence was not detected.

Abstract
INTRODUCTION 1,25-Dihydroxy vitamin D3 mediates antitumor effects in hepatocellular carcinoma. AIM We examined mRNA and protein expression differences in 1,25-Dihydroxy vitamin D3-inactivating CYP24A1, mRNA of activating CYP27B1 enzymes, and that of VDR between human hepatocellular carcinoma and surrounding non-tumorous liver. METHODS Snap-frozen tissues from 13 patients were studied for mRNA and protein expression of CYP24A1. Paraffin-embedded tissues from 36 patients were used to study mRNA of VDR and CYP27B1. mRNA expression was measured by RT-PCR, CYP24A1 protein was detected by immunohistochemistry. RESULTS Expression of VDR and CYP27B1 was significantly lower in hepatocellular carcinoma compared with non-tumorous liver (p<0.05). The majority of the HCC samples expressed CYP24A1 mRNA, but neither of the non-tumorous liver. The gene activation was followed by CYP24A1 protein synthesis. CONCLUSIONS The presence of CYP24A1 mRNA and the reduced expression of VDR and CYP27B1 mRNA in human hepatocellular carcinoma samples indicate decreased bioavailability of 1,25-Dihydroxy vitamin D3, providing an escape mechanism from the anti-tumor effect.

Abstract
BACKGROUND & AIMS Excessive consumption of ethanol is one of the most common causes of acute and chronic pancreatitis. Alterations to the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) also cause pancreatitis. However, little is known about the role of CFTR in the pathogenesis of alcohol-induced pancreatitis. METHODS We measured CFTR activity based on chloride concentrations in sweat from patients with cystic fibrosis, patients admitted to the emergency department because of excessive alcohol consumption, and healthy volunteers. We measured CFTR levels and localization in pancreatic tissues and in patients with acute or chronic pancreatitis induced by alcohol. We studied the effects of ethanol, fatty acids, and fatty acid ethyl esters on secretion of pancreatic fluid and HCO3(-), levels and function of CFTR, and exchange of Cl(-) for HCO3(-) in pancreatic cell lines as well as in tissues from guinea pigs and CFTR knockout mice after administration of alcohol. RESULTS Chloride concentrations increased in sweat samples from patients who acutely abused alcohol but not in samples from healthy volunteers, indicating that alcohol affects CFTR function. Pancreatic tissues from patients with acute or chronic pancreatitis had lower levels of CFTR than tissues from healthy volunteers. Alcohol and fatty acids inhibited secretion of fluid and HCO3(-), as well as CFTR activity, in pancreatic ductal epithelial cells. These effects were mediated by sustained increases in concentrations of intracellular calcium and adenosine 3',5'-cyclic monophosphate, depletion of adenosine triphosphate, and depolarization of mitochondrial membranes. In pancreatic cell lines and pancreatic tissues of mice and guinea pigs, administration of ethanol reduced expression of CFTR messenger RNA, reduced the stability of CFTR at the cell surface, and disrupted folding of CFTR at the endoplasmic reticulum. CFTR knockout mice given ethanol or fatty acids developed more severe pancreatitis than mice not given ethanol or fatty acids. CONCLUSIONS Based on studies of human, mouse, and guinea pig pancreata, alcohol disrupts expression and localization of the CFTR. This appears to contribute to development of pancreatitis. Strategies to increase CFTR levels or function might be used to treat alcohol-associated pancreatitis.

Abstract
Fine needle aspiration biopsy (FNAB) of focal lesions is a quick, relatively simple and cost-effective diagnostic method. However, performing aspirations and interpreting smears require skill and experience. Before initiating an aspiration the doctor needs to be aware of the limits of cytology as it is vital to know what kind of diagnostic issues can be answered upon a smear and what kind of questions cannot. Traditionally FNAB was performed without radiologic guidance, and therefore almost only palpable lesions were aspirated. Since ultrasound (US) has become widely used in medicine, it is axiomatical that FNAB is ideally performed with US guidance not only for the protection of the patients but also for targeting the lesion more safely. Several cytologists find US guidance unnecessary as a routinely used examination, which may lead to unsatisfactory smears and false negative results. This means not only a loss for the patient, but leads to a negative judgement of this diagnostic method. Our interventional cytology diagnostic team developed a working method resulting in excellent statistical results. In the followings we would like to share our experience refined the past two decades to restore the reputation of this diagnostic method.
