Background: The Cancer Biomedical Informatics Grid (caBIG™) is a network of individuals and institutions, creating a world wide web of cancer research. An important aspect of this informatics effort is the development of consistent practices for data standards development, using a multi-tier approach that facilitates semantic interoperability of systems. The semantic tiers include (1) information models, (2) common data elements, and (3) controlled terminologies and ontologies. The College of American Pathologists (CAP) cancer protocols and checklists are an important reporting standard in pathology, for which no complete electronic data standard is currently available.

Introduction: Granular cell tumors are a rare form of soft tissue tumor often arising from the skin and subcutaneous tissues of the head, trunk, or extremities, although they rarely may arise within the colon or gastrointestinal tract.Case Report:We present a case of a 28 year-old female who initially presented with recurrent granular cell tumors of the stomach treated with endoscopic polypectomy. She eventually developed a metachronous lesion within the ascending colon and underwent a segmental colectomy. We present her treatment course, pathological findings, and review of the literature of this unique condition.
