Abstract
Mast cells with endocytic and autophagic vacuoles were observed in a biopsy from a lesion of urticaria pigmentosa. In several areas of the specimen the mast cells revealed the typical morphology of mast cells which have released low molecular weight mediators, but this phenomenon did not seem to be correlated morphologically to the phagocytic activity of the mast cells. Some mast cells contained giant granules with a normal as well as an abnormal substructure.
摘要
在色素性荨麻疹病变的活检组织中观察到带有内吞和自噬空泡的肥大细胞。在标本的几个区域，肥大细胞呈现出已释放低分子量介质的肥大细胞的典型形态，但这种现象在形态学上似乎与肥大细胞的吞噬活性无关。一些肥大细胞含有具有正常和异常亚结构的巨大颗粒。
