Primary gastric plasmacytoma with massive intracytoplasmic crystalline inclusions: a case report.
摘要：
The case of a 75-year-old man with an extramedullary plasmacytoma of the stomach with peculiar histologic aspect is summarized. The cytoplasm of the proliferated cells was full of needle-shaped crystalline inclusions that made it difficult to recognize the plasma-cell nature. Under electron microscope, the crystalline inclusions were localized in the rough endoplasmic reticulum. They have a two internal line system of 75-85 of period in a 45 ° angle with the main edge. The laser-ray analysis demonstrates that these two systems delineate hexagonal areas.
