Malignant epithelioid hemangioendothelioma: a case report

Malignant epithelioid hemangioendothelioma [EH] is a rare tumor of vascular origin. We report a case of a woman who was found to have multiple hepatic masses in the right lobe of the liver on radiologic investigations, initially misdiagnosed as a metastatic carcinoma. The diagnosis of EH was made on histopathological study and confirmed by immunohistochemistry, which showed diffuse response for CD34 marker and no response to tissue CEA, HMB-45 or S-100 protein. Partial hepatectomy was made with good results

[Correlation between liver biopsy and fibrotest in the evaluation of hepatic fibrosis in patients with chronic hepatitis C]

To assess the diagnosis value of Fibrotest in comparison with liver biopsy, for the evaluation of hepatic fibrosis in patients with chronic hepatitis C. This prospective study included in 2 years [2006-2007], consecutive patients with chronic hepatitis C native to treatment. Fibrotest and liver biopsy were performed. Receiver operating characteristics [ROC] curves, the sensitivity, specificity, positive and negative predictive values were used to assess the diagnostic value of Fibrotest in comparison with the METAVIR classification. We recruited a total of 65 patients: 28 males and 37 females [mean age: 50 years]; 92% of the patients had genotype 1. The histological fibrosis results were: 3. 1% F0; 24. 6% Fl; 32. 3%F2; 29. 2%F3 and 10.8%F4. The diagnostic value of Fibrotest in the detection of significant fibrosis [F2-F4] was 0.87. A score >0.5 has a sensitivity of 85.1%, a specificity of 72.2%, a positive predictive value of 88. 9%, and a negative predictive value of 65%. The diagnostic value of Fibrotest in the detection of cirrhosis [F4] was0.85. There were 13/65 cases of discordance [20%] for fibrosis, 4 cases were attributed to biopsy and 6 cases to Fibrotest. The discordance was unexplained in 3 cases. The size of biopsy<15mm [OR=2. 82, 95% CI, 1.3-6.07; p=0.008] and the stage of fibrosis F0, F1, F2 [OR= 3.35, 95% CI, 1.1-10.2; p=0.03] were considered as risk factors of discordance in multivariate analysis. This prospective study confirmed the good diagnostic value of Fibrotest as compared with the histological analysis of liver biopsy

Evaluation of nutritional status in patients with liver cirrhosis

Malnutrition is a frequently reported complication in patients with liver cirrhosis. It has a high clinical and economic impact reflected by an increased morbidity and prolonged hospital stay. This preliminary prospective study aimed to determine the prevalence of malnutrition in hospitalized cirrhotic patients and to investigate whether biological and anthropometric parameters are a valuable tool for identifying malnutrition in these patients. The nutritional status of 44 consecutive cirrhotic patients [21 men, 23 women] was assessed according to the anthropometric measurements and biochemical analysis. The diagnosis of malnutrition was based on diminished values of Mid arm muscle circumference [MAMC] and/or Triceps skinfold thikness [TST] below the 5th percentile or less than 60%. The aetiology of cirrhosis was viral hepatitis in 29 patients [66%]. Cirrhosis was classified Child Pugh A, B or C in respectively 9, 26 and 9 patients; 37 patients [84%] have mild or tense ascite. In this study, malnutrition was found in 35 patients [79.5%], whereas 9 patients has a good nutritional status. TST and MAMC less than 60%was found in respectively 72%and 25%of patients. No significant statistical difference in epidemiological characteristics was found between malnourished and well-nourished patients. TST and MAMC decreased significantly according to the Child score [p=0.014 and 0.032 respectively; a positive correlation was found between these two paramelers and the severity of cirrhosis. In this study, the high prevalence of denutrition was associated with the severity of cirrhosis. Anthropometric parameters are valuable tools for malnutrition diagnosis

Transverse myelitis associated with chronic viral hepatitis C

HCV infection could cause several extra hepatic diseases including mixed cryoglobulinemia, Peripheral neuropathy is the most common complication of mixed cryoglobulinemia. In addition to cryoglobulinemia's neuropathy, transverse myelitis had been related to had infection. But causality of this association is not clearly established. A 55-year-old man presented with motor deficiency in lower extremities and urinary retention Neurological exams showed a spastic paraparesis and proprioceptive ataxia. Spinal MRI revealed a contrast enhancing signal abnormality within the spinal cord extending from Levels C3 to CS. Serology hepatitis C and viremia were positive. Clinical diagnosis of acute demyelinating sensorimotor polyneuropathy associated to chronic hepatitis C was etablished. Screening of HCV infection must be done in patients with transverse myelitis and no clear aetiology

[Microcystic serous pancreatic cystadenoma]

The pancreatic cystic serous neoplasms are divided into two categories: benign serous cystadenoma [SCA] and malignant serous cystadenocarcinoma. Furthermore, based on the macroscopic appearances, SCAs are subdivided into serous microcystic adenomas [SMAs] and serous oligocystic or macrocystic adenomas. Report of a new case of SMA in which we emphasize on the diagnostic difficulties encountered against such tumor despite its relatively radiological easiness compared to the other variants. We report the case of 84 year-old-woman with a microcystic serous cystadenoma of the pancreas which was identified on pathologic examination of the surgical specimen, after unconclusive abdominal ultrasound and computed tomography [CT]-scan. This case describes this rare entity and emphasizes that the diagnosis of such entity is still based on pathological examination after tumor removal

[Solid pseudopapillary tumors of the pancreas: a pediatric case report]

Solid pseudopapillary tumors of the pancreas are extremely rare and mostly seen in young females. It is often diagnosed incidentally or during investigations of gastrointestinal complaints. Report of a pediatric case of this tumor. We report the case of a 15-year old teenager who presented with painful abdominal tumefaction. Imaging findings were a 12 cm solid and cystic mass originating from the tail of the pancreas. A distal pancreatectomy with splenectomy was performed. Pathologic examination concluded to solid pseudopaprillary tumor. Evolution was favorable with no recurrence 18 months after surgery. Histological examination confirms the diagnosis and allows, with the help of immunohistochemical study, to rule out some differential diagnoses such as pancreatoblastoma, acinar tumors and endocrine tumors. Prognosis of solid pseudopapillary tumors of the pancreas is excellent after radical resection and recurrences are rarely seen
