Nasal and systemic eosinophilia associated with solid intestinal tumors, a case report and review of the literature

Abstract

The authors report the study of a clinical case, which presented eosinophilia both in the secretion of the nasal mucosa and in the blood count. After a careful examination of all the pathologies related to hypereosinophilia, through a clinical study, they have documented the presence of an adenocarcinoma located in the ileocecal junction of the colon. From what has been documented it is clear that only a clinical observation of precision, carried out above all through nasal cytology and colonoscopy, is able to diagnose an important pathology, such as oncology. For the literature review we used the Scopus and PubMed search engines to analyze other authors who were interested in the relationship between eosinophilia and colorectal cancer. Much of the studies analyzed reported a close relationship between the presence of tissue eosinophilia and tumor, and the prognosis of colorectal cancer.
