Micrograph of a small, well-circumscribed colonic leiomyoma arising from the muscularis mucosae and showing fascicles of spindle cells with eosinophilic cytoplasm and elongated, cigar-shaped nuclei Immunohistochemistry for β-catenin in uterine leiomyoma, which is negative as there is only staining of cytoplasm ...
Grading systems are also different for many common types of cancer, though following a similar pattern with grades being increasingly malignant over a range of 1 to 4. If no specific system is used, the following general grades are most commonly used, and recommended by the American Joint Commission on Cancer and other bodies: [ 2 ]

In one study, metastatic disease was detected in 23% of patients and occurred at a median of 10 months (range, 2–77 months) after resection of the primary tumor. In a review of multiple studies, the risk of developing metastases for lower grade MFS (defined in the following section) was <5% and for higher grade tumors was 25–30%. [11]
An inflammatory fibroid polyp (IFP) is an uncommon digestive system tumor. [1] J. Vanek initially identified it as a separate pathological entity in 1949 when he reported six case reports of eosinophilic infiltration in gastric submucosal granulomas. [2] It is a single, non-encapsulated polypoid lesion that is typically submucosal.
