[INTRODUCTION - Haemangioma is the most common type of benign hepatic tumors. Haemangiomas are usually asymptomatic, except for those that exceed five centimeters in size and are called “giant” haemangiomas. Malignant transformation has not been noted and therefore only regular follow-up is recommended for smaller haemangiomas. Surgical intervention becomes necessary only if symptoms or complications occur. Nevertheless, atypical presentation can cause a significant differential diagnostic problem. CASE REPORT - The authors report the case of a 51-year old woman with a focal hepatic abnormality diagnosed during a routine abdominal ultrasound examination. Results of the subsequent computed tomography scan suggested a multiple hepatocellular carcinoma based on the morphological appearance. Following oncology consultation, she was admitted to our department for liver biopsy. Histology did not reveal any malignancy. This result together with the lack of symptoms and complaints and the normal laboratory test results shifted the likely diagnosis towards a benign haemangioma. Blood-pool scintigraphy confirmed this diagnosis. CONCLUSIONS - Haemangiomas are benign hepatic tumors. They are often diagnosed accidentally, by routine abdominal ultrasound examination. If an abdominal ultrasound raises suspicion of haemangioma, abdominal MRI scan or blood-pool scintigraphy is recommended to be performed in order to exclude malignancy for lesion sizes of <2 cm or >2 cm, respectively. The reported case is considered important because of the differential diagnostic problems the large size and the atypical presentation of the given haemangioma imposed. Ultrasound-guided liver biopsy via fine-needle aspiration has previously been contraindicated. This invasive procedure can be performed in patients with focal hepatic pathology if diagnosis cannot be established by non-invasive tests, especially if malignancy is suspected. It can be performed conditional on the localization of the tumor, the patient’s general condition, the laboratory results, and if there is a therapeutic consequence of the biopsy results.]

[Treatment of acute pancreatitis, with special regard to pharmaceutical therapy]

DÖBRÖNTE Zoltán

[Treatment of acute pancreatitis is mainly supportive, including the correction of any factors causing or sustaining the disease process, efforts to limit complications, as well as treatment of complications. Pharmaceutical efforts to influence the pathophysiological events with protease inhibitors or by influencing the release of the pro-inflammatory cytokine cascade did not prove to be effective, so there is no known effective and specific drug therapy for clinical use. Adequate pain control is an important component of pharmaceutical management, and - although yet controversial - early antibiotic prophylaxis and effective antimicrobial treatment of the inflammatory complications (infected necrosis or fluid collection, SIRS, sepsis) have probably a determining role in the outcome of severe necrotizing pancreatitis. Carbapenems proved to be the most potent antibiotics. For the prevention of the not infrequent fungal superinfection in acute pancreatitis, early administration of fluconasole can also decrease mortality. Surgery is indicated in the first stage of infected necrosis and infected pancreatic and peripancreatic fluid collections. In certain patients with a high operative risk, endoscopic or percutaneous drainage with lavage can also be worth trying. Optimal conditions for the treatment of severe necrotizing pancreatitis, as well as adequate management of multiple organ failure can only be warranted at an intensive care unit. In the chemoprevention of pancreatitis complicating endoscopic retrograde cholangiopancreatography (ERCP), non-steroidal anti-inflammatory drugs promise a new therapeutic option. There are insufficient data about the beneficial effects of the protease inhibitor ulinastatin, and results with nitroglycerin are contradictory.]

[BENIGN SOLITER FIBROTIC TUMOR OF THE PLEURA - A CASE REPORT]

BOHÁCS Anikó, TAMÁSI Lilla, SOMOSKÖVI Ákos, MÉSZÁROS Zsolt, SÁPI Zoltán, BÁRTFAI Zoltán

[INTRODUCTION - Rare asymptomatic pleuropulmonary neoplasms can represent serious differencial diagnostic difficulties both for clinicans and pathologists. Immunohistochemical tests are essential tools for the diagnosis of soliter fibrotic tumor of the pleura. These tests are also of diagnostic and prognostic importance. CASE REPORT - The report summarizes the case of an asymptomatic 63 years old man. The patient was admitted to hospital with a parahilar infiltrate of the right lung. Based on this chest X-ray abnormality pulmonary malignancy was suspected. The patient was referred to surgical intervention and the diagnosis of was based on post-surgical histology. These fibrotic tumors have typical immunohistochemical features. Although the histomorphology of the tumor suggested the presence of a benign tumor the p53 positivity and focal CD34 positivity indicated the possibility of malignant transformation as well. The patient is alive 17 months after surgery and there is no relapse of the disease. CONCLUSION - Although histologically benign, soliter fibrotic tumors of the pleura may occasionally transform into malignant variants. Therefore complete surgical resection and longterm clinical and close radiological follow-up is recommended for these patients. Clinician can plan well ahead the frequency and time of the follow-up with the help of the prognostic factors of hystology.]

[Pancreatic carcinoma mimicking primary retroperitoneal fibrosis]

RÉDEI Csaba, ESZES Noémi, HAJNAL Péter, MÁTÉ Miklós, SIMON Károly, TÓTH Julianna, POZSÁR József, TOPA Lajos

[INTRODUCTION - One of the defining feature of pancreatic ductal adenocarcinoma (PDA) is the presence of extensive desmoplasia. The volume of stroma production can be disproportionate relative to mass of the tumor. Primary retroperitoneal fibrosis (PRF) is characterized by progressive accumulation and spread of connective tissue in the retroperitoneal space often leading to entrapment of ureters and/or the distal part of the duodenum. The large amount of stroma can mimic the radiologic features of PRF. We present a case when the diagnosis of pancreatic ductal adenocarcinoma was delayed because of the tumor showed retroperitoneal spread and imaging studies were distinctive for PRF. CASE REPORT - The past medical history of the 77 year old patient was significant for chronic renal failure of postrenal origin diagnosed one year before. The abdominal CT-scan performed six month ago was unremarkable except for focal stricture and upstream dilation of both ureters. After a relatively uneventful course during the past six months, the patient presented with abdominal distension and vomiting of five days period. Abdominal CT-scan revealed an extensive infiltration of the retroperitoneal space by a tissue with radiologic features characteristic for PRF. The fibrotic tissue involved the prerenal fascia, both ureters, and the third part of the duodenum. Duodenoscopy disclosed complete duodenal obstruction caused by an external compression at the level of ligament of Treitz. At surgery, a hard, fibrous tissue extending form the hepatic hilum down to the pelvis have been seen. The infiltrating tissue also entrapped the distal duodenum leading to its obstruction. Histologic evaluation of specimens taken at surgery showed features of fibroplastic PDA. CONCLUSION - PDA may present as an extensive retroperitoneal fibrosing process without detectable intrapancreatic tumor on radiologic studies. Obsructive signs of any retroperitoneal organ (ie. ureters, duodenum) should raise the possibility of retroperitoneally expanding PDA.]

[Thallium poisoning induced polyneuropathy - clinical and electrophysiological data]

LUKÁCS Miklós

[Introduction - The aim of the study was the electrophysiological investigation of thallium induced polyneuropathy. Beyond the rarity of the illness, the motivation of this work was the possibility of following up the pattern of neuronal damage. Thallium is one of the most toxic heavy metal and its wide use increases the chance of chronic or accidental acute poisoning. The entero-hepatic circulation makes the accumulation of this toxic agent in tissues possible, mostly in neurons, in the epithelial cells of the digestive tract, in the germinative cells of the skin and testicles. In addition to alopecia and digestive complaints, the clinical picture of thallium poisoning is dominated by neurological signs. Severe axonal polyneuropathy develops in almost all cases, with further damage to the retina and impairment of cognitive functions being not unusual. The diagnosis is confirmed by finding high levels of thallium in body fluids, especially in saliva and urine. Case report - Electrophysiological examination of our accidentally poisoned patient revealed severe, sensory-motor, predominant motor axonal polyneuropathy and pointed out some aspects of the pattern of neurotoxic process: the initially distal lesion, the dying-back course and the capacity for regeneration. Conclusion - Because thallium has the same molecular targets as potassium ion thus impairing the energetical supply of the nerve cell, the most effective treatment is carefully loading with potassium. If recognized and treated early, thallium poisoning has a favourable prognosis.]

[DIVERTICULOSIS, DIVERTICULITIS - SYMPTOMS, DIAGNOSTICS AND TREATMENT]

NÉMETH Anna Mária, ENDER Ferenc, BANAI János

[Diverticulosis of the colon is frequent in developed countries. Decreased intake of dietary fibre have been implicated as an important pathogenetic factor. Most of the affected patients are asymptomatic but 10-20% of them have abdominal problems. Clinical manifestations range from simple, non-complicated form (abdominal pain, distension, constipation, urgency etc.) to severe complications (diverticulitis, abscess, peritonitis, perforation, haemorrhage etc.) The diagnosis and therapy of different forms of diverticular disease can be very simple but in several cases differential diagnostical problems and therapeutical difficulties may arise. The gold standard for establishment of uncomplicated diverticulosis is the barium enema or colonoscopy. In case of complicated forms non-invasive methods (US, CT scan, CT-colonography, MRI) have to be preferred. These examinations have no risk for perforation and extraintestinal pathology (air, fluid, abscess) can be detected. Colonoscopy or angiography are the methods of choice in case of haematochesia. The choice of therapy is based on clinical presentation, symptoms and pathology. Fibre supplementation is recommended for patients with diverticulosis without symptoms. In case of noncomplicated symptomatic diverticular disease fiber supplementation or cyclic administration of broad spectrum, poorly absorbable antibiotic can be effective in the prevention of inflammatory episodes and complications. If some of the severe or recurrent complications can not be treated conservatively, surgery is necessary. Prevention of diverticulosis and diverticular disease has to be emphasized. While fibre supplementation in the diet is recommended, other efficacious preventive strategies remain to be identified.]
