Liver abnormalities seem a very rare association in Turner’s syndrome, only reported in a few anecdotal cases. We report the clinical and morphological findings in 3 patients who presented with cholestasis. One of them had a definite diagnosis of primary sclerosing cholangitis, in whom the natural history was complicated by the development of two distinct tumors. A review of the few cases described in the literature and our own case reports support the hypothesis that liver disease in Turner’s syndrome may have a variety of expressions including cholestasis.
Benign recurrent intrahepatic cholestasis (BRIC) is an autosomal recessive liver disease characterized by multiple episodes of cholestasis without progression to chronic liver disease. On the basis of recent evidence of locus heterogeneity, we studied 19 subjects (7 affected members) of a BRIC family. Male-to-male transmission and the presence of affected females suggested autosomal dominant inheritance. Blood samples were collected after informed consent. Subjects were genotyped by using markers mapping to 18q and 2q24 region, respectively, where the genes FIC1 and FIC2 have been mapped. Segregation of haplotypes excluded the two regions in our family. These findings suggest further genetic heterogeneity of the origin of BRIC.
Introduction. Ten cases of dome-type adenocarcinoma of the colon have been reported so far. Most of them were presented as early lesions, with endoscopic and microscopic distinguishing features. Methods and Results. A raised plaque was removed from the right colon during colonoscopy in a 56-year-old man. Histopathological examination showed a cancerized adenoma invading the submucosa with several typical features of dome-type adenocarcinoma, in particular the associated prominent lymphoid tissue. Immunohistochemistry showed retention of the mismatch repair proteins MLH-1, MSH-2, MLH-6, and PMS-2. Conclusion. We report an additional case of dome-type adenocarcinoma of the colon as an early, low-risk, and microsatellite stable tumor, indicating that this particular histotype may deserve specific consideration for both classification and management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
