ABSTRACT
It results cholelithiasis is very frequently associated to colorectal cancer. Clinical and autoptic studies thereabout result to be doubtful. In the present research, the Authors evaluated the proliferative activity of colonic mucous membrane, through the mitotic index, and the secretion of mucins, with histochemical methods, in control subjects and cholelithiasic patients. The results show no significant differences in both groups; the data obtained are discussed in the light of the importance of the biologic parameter considered in the evaluation of risk groups for colorectal neoplasms and, moreover, as morphologic support to the clinical question.

Some studies suggest cholecystectomy and the cholelithiasic disease are frequently associated to some neoplasms of the digestive tract. Cholecystectomy, through the physiopathologic alterations it causes, seems to assume the role of factor of risk for the development of a gastric neoplasm. The authors reviewed their casuistry by analysing the percentages of subjects in whom the gastric neoplasm was associated to a previous cholecystectomy or a concomitant cholelithiasis. The data obtained do not support the hypothesis that cholecystectomy or the "lithogenicity of the biliary ducts" may be a factor of risk for gastric cancer.

The authors show two cases of cystic lymphangioma, one located at the neck, the other in the inguinal region, both arising in aged patients. From the study of such cases, the Authors start for studying the etiopathogenetic and histologic aspects, dwell upon the clinics and diagnosis of such neoplasms, and indicate as the sole radical treatment the surgical extirpation.
