RESUMO
Intracranial germ cell tumors are rarely seen and typically localize in the pineal or suprasellar region. The largest category of germ cell tumors is dysgerminoma. To describe clinicopathological features and immunohistochemical profile of dysgerminomas. We report three cases of central nervous system dysgerminomas. There were two young women and a man who were 6, 11 and 23 year-old. They presented with symptoms of insipidus diabetes [n=3] with association to visual field defects in the third case. Radiological findings showed a supra seller lesion in two cases. Double localization in the pineal and suprasellar regions was seen in the third case. Histologic examination and immunohistochemical study of surgical specimen were consistent with primary central nervous system dysgerminoma

Hydatidosis is a parasitic endemic disease in Tunisia. The liver and lung are the most common sites of involvement; however, it can develop anywhere in the body. The aim of the present study was to analyse the epidemiological features of extrapulmonary hydatid cysts and compare our results with those reported in literature. Aretrospective study of 265 extrapulmonary hydatid cysts collected over the 18-year period from 1990 to 2007 was undertaken. There were 101 male and 164 female patients [sex ratio M/F= 0, 61] ranging in age from 2 to 84 years [mean age = 38, 7]. In our series, hydatid cysts involved mainly the kidney [24, 1%], the central nervous system [22, 6%], the liver [19, 6%] and the spleen [11, 3%]. The other less frequent sites included the peritoneum [n = 9], heart [n = 9], bone [n = 6], adrenal gland [n = 4], epiploon [n = 4], orbit [n = 4], ovary [n = 3], prostate [n = 2], bladder [n = 2], breast [n = 2], Douglas' cul-de-sac [n = 2], diaphragm [n = 1], testis [n = 1], broad ligament [n =1], mediastinum [n = 1], nasal cavity [n = 1], soft tissue [n = 1], abdominal wall [n = 1], parotid gland [n = 1], psoas muscle [n =1], synovia [n = 1], thymus [n =1] et le pancreas [n = 1]. In contrast to literature, our results show that hydatid cysts of the kidney and of the central nervous system are more frequent than hepatic location which occupies the 3rd rank

The aims of our study were to determine the frequency of granulomatous hepatitis in patients with peritoneal tuberculosis, to identify factors for high risk and whether it is associated with higher frequency of antituberculous treatment side effects. We carried out a prospective study on patients with histologically proven peritoneal tuberculosis between January 1996 and December 2005. We performed a liver biopsy in all the patients before starting the antituberculous treatment. Granulomatous hepatitis was systematically searched in all patients. The study was conducted in 52 patients, 9 men and 43 women of median age of 35,5 years. A granulomatous hepatitis was seen in 24 patients [46%]. In univariate analysis the factors associated with a high risk of liver involvement were a higher level of gamma-G1utamyl transpeptidase [44.5 + 36.8 lU/l vs 23.3 + 9.28 lU/I p=0.005], a higher level of phosphatases alkalines [233.9 + 96.6 lU/l vs 189.4 + 49.9 lU/l p=0.03] and a lower level of cholesterol [1.22 + 0.2 g/l vs 1.56 + 0.3 g/l p<0.0001]. In multivariate analysis, only a cholesterol level lower than 1,31 g/l was significantly associated with a granulomatous hepatitis [p=0.006 OR [IC95%]: 0.10 [0.02-0.52]]. We have found a frequent liver involvement in the case of peritoneal tuberculosis [46%]. Cholesterol level lower than 1,31 gr/l was an independent predictor of granulomatous hepatitis in patients with peritoneal tuberculosis. We suggest, in this case, that percutaneous liver biopsy can be considered as an alternative to laparoscopy
