【Abstract】 Five cases of mucoid carcinomas in the human breast had been studied by the light and electron microscopy.Tumor cells usually arranged in sheets or clusters lying in pools of mucin. These cells were divided into light and dark cells. Dark cells possessed the secretory ability, which were characteristic by well-developed Golgi complexes and filled with secretory vesicle. Light cells possessed the ability of multiplication, and the cytoplasmic organ-elles were less conspicuous, but demosomes were often observed.The ultrastructural appearences dispelled any doubt about the epithelial origin of the mucin.This investigation suggests to us that the better prognosis of mucoid carcinoma is due to the progressive mucin production by the tumor cells resulting in the degeneration and death of the cells themselves.更多还原
