The His1069Gln mutation in the ATP7B gene in Romanian patients with Wilson's disease referred to a tertiary gastroenterology center.

Background And Aim: Wilson's disease (WD) is a rare autosomal recessive disease. More than 500 mutations have been described so far, out of which 29 in exon 14. H1069Q mutation in the exon 14 of ATP7B gene is the most frequently encountered in Europe.

Histopathological diagnosis of cutaneous vascular sarcomas.

Cutaneous sarcomas represent a heterogeneous group of mesenchymal lesions. This study investigates the histopathological and immunohistochemical features in different cases of angiosarcoma and Kaposi's sarcoma (cutaneous vascular sarcomas), which are representative for medical practice. The clinical-histopathological-immunohistochemical correlations render possible the differential diagnosis and a proper treatment can be applied to obtain a favorable prognosis.

Apoptosis in cutaneous melanomas.

Cutaneous melanomas has become one of the most discussed and studied tumor because its particular immunologic development but also its increasing rate worldwide in the last decades. Even thought many patients are diagnosed at an early stage, the death rate continues to rise due to the increasing incidence of more advanced lesions. The aim of this study is to detect apoptosis in 30 cases of cutaneous melanomas using the in situ end-labeling technique (TUNEL) who quantify apoptotic cell death at single cell level and tissues.
