Research output: Contribution to journalArticlepeer-review


Dolichocolon (redundant colon) is an underdiagnosed cause of severe constipation in humans. The clinical presentation reported here in a rhesus macaque closely resembles that of intestinal adenocarcinoma, the most common neoplasia in macaques. Dolichocolon should be considered in differential diagnosis of macaques with anorexia, weight loss, and constipation.
