RESUMO
The literature reports an annual incidence of 5,900 cases of anal cancer in the developed countries. These involve three different anatomic zones: carcinoma of the anal canal, perianal carcinoma (formerly known as carcinoma of the anal margin, located at a distance of less than 5cm from the anal margin), and carcinoma of the perianal skin (at a distance greater than 5cm from the anal margin). Basal cell carcinoma of the perianal region is an uncommon tumor (0.27% of all diagnosed basal cell carcinomas) that in the majority of cases is treated by resection with disease-free margins. It must be differentiated from the basaloid and epidermoid variants of carcinoma, given that it has good outcome and its spread potential is practically null.

Solitary fibrous tumors are a very unusual group of spindle-cell neoplasm of adults; they were described for first time in the 18th century. They locate mainly in parietal and visceral pleura, lung parenchyma and pericardium. There are numerous reports that document their extrapleural location and we can find it in any place in the body, but mesenteric localization is extremely unusual.

The gastric inflammatory fibroid polyp (GIFP) is a rare benign tumor that is localized mainly in the antrum and presents endoscopically as a submucosal mass. The usual reported presenting size ranges among 1 and 5 cm. In this case report we present the largest GIFP published in the literature in a very uncommon localization, this is a 9.1 x 6.3 cm lesion in the gastric fundus.
