Differences in colorectal cancer patterns between right and left sided colorectal cancer lesions.

Purpose: Colorectal carcinomas that arise proximal (right) or distal (left) to the splenic flexure exhibit different clinical and biological characteristics. Although various hypotheses have been proposed to explain these differences, their origin remains unclear. In this study we investigated the clinicopathologic differences between left and right colon tumors and comment on the possible explanatory theories behind them.

The value of proliferation indexes in breast cancer.

Introduction: During the past several years, the Ki-67 antigen has gathered great interest in its role as a prognostic marker. Nevertheless, despite the large number of published papers, the role of Ki-67 in clinical practice remains controversial.

Aim: To evaluate the association between Ki-67 immunoreactivity and other clinicohistopathological parameters.

Recurrent erythema multiforme after alcohol ingestion in a patient receiving ciprofloxacin: a case report.

The incidence of cutaneous adverse reactions to quinolones is low; moreover their development in patients with concomitant alcohol consumption is a phenomenon that has been scarcely reported. We present a case of 46-year-old male who developed erythema multiforme after ingestion of alcohol, while being treated with ciprofloxacin. The lesion was self-limiting and abstinence from alcohol permitted the completion of the course of therapy without any other adverse reaction.

Desmoid tumor of the supraclavicular region: a case report.

Desmoid tumors are rare, benign fibroblastic tumors that are locally infiltrative and can cause extensive morbidity by destruction of adjacent vital structures. Due to the rarity of these tumors, evidence regarding optimal treatment protocols is drawn from case reports and single-arm series with small patient numbers. We report a case of a patient with a desmoid tumor of the left supraclavicular region that was diagnosed and treated in our department and a review of the current literature.
