The finding that Cajal cells express c-kit (CD117), a tyrosine kinase, is a considerable development.
Ten large magnification areas were counted in the same specimen from each case, and the number of Cajal cells was quantitatively determined.
It was determined that the Cajal cells were encountered more frequently in the control group.
The number of cells in 10 separately screened areas was calculated and the total number of Cajal cells in the areas, 0-3, 4-8, and >8 cells were regarded as sparse, few and many, respectively.
c-kit positive Cajal cells, which are easily distinguished from the mast cells in the UPJ, were demonstrated in this study.
Although the ultrastructural configurations in the gastrointestinal and neuronal systems have frequently been evaluated via electron microscopic methods, studies about the electron microscopic evaluation of Cajal cells in human UPJs have not been encountered in the literature.
94) These lesions have been variably designated as sporadic Cajal cell hyperplasia, microscopic GISTs, GIST tumorlets, or "seedling" GISTs.
Sporadic Cajal cell hyperplasia is common in resection specimens for distal oesophageal carcinoma; a retrospective review of 77 consecutive surgical resection specimens.
16) In both cases, these PDGFRA-positive cells could be the normal counterpart of IFPs (and PDGFRA-driven GISTs), as happens with Cajal cells for KIT-driven GISTs.
Both types of cells express the CD 117 protein, but Cajal cells do not stain for CD 34 nor for other muscle cell antigens frequently seen in GIST cells.
