Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors in the GI tract and thought to arise from interstitial cells of Cajal. Histopathological diagnosis of GIST is made in association with immunohistochemical staining with a panel of antibodies that generally include CD34, CD117, S-100, SMA, and DOG1. Celiac disease (celiac sprue) is a malabsorptive syndrome of the small intestine which shows characteristic morphologic changes in the proximal small intestine.
In classic cases varying degrees of chronic inflammation is present in the lamina propria and surface epithelium. The disease results from sensitivity to dietary gluten in certain individuals, especially carrying HLA-DQ2 and HLA-DQ8 haplotypes. The tumors are most common in stomach followed by intestine but extremely rare in esophagus. Necrosis per se has not been identified as an independent prognostic marker, but necrosis is most commonly seen in tumors larger than 10 cm, and size has been recognized as an independent prognostic marker. More than 90% of the tumors show positive staining for CD117 and DOG1 and about 70% show staining for CD34.

The most visible feature is the total or subtotal loss of villous architecture imparting an appearance akin to colon.
The resulting inflammation is characterized by CD8+ T-cells in the surface epithelium (shown by two arrows and confirmed by immunohistochemistry) and CD4+ T-cells in the lamina propria admixed with abundant plasma cells (shown below the line). In spindle cell variety, the cells can be arranged in palisaded (schwannoma-like), storiform, and whorled formations.
Examples of single-user license include conferences, seminars, presentations, and one-time teaching courses.
The loss of villous architecture is the result of an inflammatory and autoimmune damage to the epithelial cells. The broad arrow at the bottom shows moderate chronic inflammation with small lymphocytes, plasma cells, and eosinophils. However, the prognostic outcomes of size and mitotic count vary for gastric and intestinal tumors. A number of cellular variations are seen with cells showing epithelioid, plasmacytoid, round-cell, and vacuolated appearances. Cases which lack staining for CD117 may show mutations in the CD117 gene or PDGFR-alpha gene.


Examples of multi-user license include books, book chapters, educational material, and other publications with multiple copies. Note the flattened top of the duodenal mucosa (top arrowhead) and the presence of a few remaining Brunner’s gland.
The withdrawal of gluten from diet improves clinical symptoms with histologic improvement but symptoms reappear with characteristic histologic findings upon challenge to gluten diet.
Patients with persistent unresolved and refractory inflammation are at increased risk of developing small intestinal T-cell lymphoma knows as “Enteropathy-associated T-cell lymphoma (EATCL)” and also small intestinal adenocarcinomas.
Although the histopathologic findings are characteristic they are not absolutely specific to this disease as similar findings may be seen with tropical sprue. Most tumors show mutations in the c-Kit gene (exon 11 most commonly) or PDGFR-alpha gene (exon 18 most commonly).
