GISTs are mesenchymal tumors representing approximately 1% of all gastrointestinal neoplasia. Their concurrence with colorectal cancers is rare.
CASE REPORT: We present a case of coexistence of colon adenocarcinoma and GIST of the ileum in a 68-year-old white woman.
CONCLUSIONS: The coexistence of mesenchymal and epithelial neoplasia is very challenging; further research is needed to clarify the role of oncogenic mutations and signalling pathways in carcinogenesis of neoplasia of various histiogenic origins.
