Regression of steatohepatitis-related cirrhosis.

The authors document regression of cirrhosis in an obese 56-year-old man after significant weight loss by sequential liver biopsies. The patient had a known history of steatohepatitis. His initial laboratory workup 6 years earlier revealed elevated liver enzyme activities and blood triglyceride levels, and negative viral hepatitis serology screen. A liver biopsy at that time showed histological features consistent with precirrhotic stage of active steatohepatitis. A liver biopsy performed 4 years later revealed progression of the disease to cirrhosis. Following this diagnosis he went on a special strict diet and lost 49 kg. His body mass index decreased from 46 to 28 during a 2-year period and his liver enzyme activities returned to normal. A liver biopsy at this time demonstrated significant regression of the liver fibrosis and disappearance of the steatosis and necroinflammation. In conclusion, massive weight loss resulted in resolution of liver fibrosis in this obese patient with steatohepatitis-related cirrhosis.

[Retrospective evaluation of the alveolar echinococcosis cases between 1980-2010 in Erciyes University Hospital]. / Erciyes Üniversitesi Hastanesinde 1980-2010 Yillari Arasinda Alveoler Ekinokokkozis Saptanan Olgularin Retrospektif Degerlendirilmesi.

OBJECTIVE: Alveolar echinococcosis is an uncommon parasitic disesae confined to the Northern Hemisphere. There is limited data regarding the incidence of the disease in Kayseri. METHODS: Clinicopathologic features of the cases with the diagnosis of alveolar echinococcosis reviewed between 1980-2010. RESULTS: Twenty-nine cases of alveolar echinococcosis were found. There were no significant distribution differences during the study period. 28 of the 29 cases were localised in the liver, whereas one case was localised in the omentum. Sixteen of the 29 cases were male (55%) and 13 were female (45%). The age distribution of these cases varied between 33 and 80. Thirteen cases resided in Kayseri, 2 cases resided in Erzurum, 1 each case resided in Adana, Ardahan, Kars, Nigde, Nevsehir and Yozgat. We could not obtain information from the remaining 8 cases. Abdominal pain was the main symptom in 8 cases, jaundice in 2 cases and fatigue and fever in one case on admission. One case was detected incidentally. All of the cases were diagnosed by histologic examination. CONCLUSION: The data about the alveolar echinococcosis is limited due to its low prevelance. Alveolar echinococcosis cases were detected in Kayseri with a lower incidence than in the East Anatolian region. This report will add data about the incidence of the alveolar echinococcosis.

Primary hepatic carcinosarcoma.

BACKGROUND: Primary hepatic carcinosarcoma is a rare malignant tumor containing an intimate mixture of carcinomatous and sarcomatous elements. Reports on risk factors, epidemiology, and pathogenesis of the tumor as well as the experience in its treatment are limited. METHOD: We present a case of primary carcinosarcoma of the liver in a 69-year-old man who complained of right hypochondrial pain and weight loss for two months. RESULTS: Magnetic resonance imaging revealed a 14 x 12 cm mass in segments 7-8 and 4 of the liver with vena hepatica invasion. An ultrasonography-guided biopsy showed osteoid tissue without osteoblastic rimming. Vascular structures accompanied the osteoid tissue. The patient underwent surgery after a diagnosis of hemangioma. Intraoperative frozen sections revealed a carcinosarcoma associated with an osteosarcoma and cholangiocellular carcinoma components. CONCLUSIONS: Preoperative diagnosis of this rare primary hepatic malignant tumor may be difficult by biopsy owing to intratumoral heterogeneity. Highly mature areas of the osteosarcomatous component may lead to misdiagnosis of metaplastic bone tissue. Clinicopathologic features of this rare entity are discussed.

Significance of intraepithelial lymphocytes in appendix.

The aim of this study was to investigate the importance of the increase in intraepithelial lymphocytes (IELs) in the mucosa of the appendix. One hundred and four retrospective appendectomy specimens were examined to evaluate the IELs. Intraepithelial lymphocytosis was identified in 11.5% (12 cases) of the specimens. Of these 12 cases, 6 cases with intraepithelial lymphocytosis were associated with parasitic infection. No increase in IELs was found in the 36 appendices that were removed in other primary operations. A wide range of immunologic stimuli can raise IELs in the gastrointestinal system. However, in appendectomies with clinical signs of acute appendicitis, an increase in IELs is more likely to be related to parasitic infection. This increase should be considered for the diagnosis of parasitic infections.

Localized gastric amyloidosis: a case report.

Local deposition of amyloid without systemic involvement is rather uncommon and has been found in many organs. A 67-year- old man was admitted to our hospital presenting with weight loss, fatigue and poor appetite. Blood work and bone marrow examination revealed megaloblastic anemia. Upper gastrointestinal endoscopy reveeled e purple polypoid wass lesion of 5mm eliameter in the paracardiac region. Histopathologic examination of the gastric biopsy showed the deposition of amyloid materials in the mucosa. The patient had no evidence suggesting systemic amyloidosis. We report a rare case of localized amyloidosis of the stomach. The clinical and pathological features of this rare condition and association with megaloblastic anemia are discussed.

Adrenocortical adenoma associated with inadequately treated congenital adrenal hyperplasia.

We report a 6 year-old boy with the simple virilizing form of 21-hydroxylase deficiency in whom an adrenal adenoma developed following 5 years of steroid treatment. Extremely high levels of basal serum 17alpha-hydroxyprogesterone as well as an exaggerated response of 17alpha-hydroxyprogesterone to adrenocorticotropic hormone confirmed congenital adrenal hyperplasia at 7 years of age. Initially elevated serum steroid levels were restrained by high dose hydrocortisone therapy, but he chronically tended to take inadequate doses of glucocorticoid. At 12 years of age an adenoma was found in the cortex of the hyperplastic right adrenal gland. The importance of early diagnosis and compliance with medication in the simple virilizing form of 21-hydroxylase deficiency is stressed.
