Abstract:
Primary T-cell lymphoma of the stomach is very rare. We report two cases of primary gastric T-cell lymphoma, one of which had a morphological appearance and a phenotype that were similar to those of node-based peripheral T-cell lymphoma. The other case was related to human T-cell lymphotropic virus type I and displayed a feature of lymphoma cell pleomorphism. The lymphoma cells were both positive for Ki-1/CD30.
