恶性组织细胞增生症最初称为组织细胞性髓性网状细胞增多症。1964年全国血液学术会议以后,国内通常称为恶性网状细胞病。有关本病临床和病理方面的报告,国内尚不少见,但至今未见超微结构观察的报导。我们最近遇到一例,对其骨髓内异常细胞进行电子显微镜(下简称电镜)观察,现报告如下,并对本病的命名和超微结构特征等问题,进行讨论。 Malignant histiocytosis was originally called histiocytic myelocytosis. After the national blood symposium in 1964, the domestic commonly referred to as malignant reticulosis. The clinical and pathological reports of this disease, the domestic is not uncommon, but so far no reports of ultrastructural observation. We recently encountered a case of abnormal bone marrow cells under electron microscopy (hereinafter referred to as electron microscopy), are reported below, and the naming of the disease and ultrastructural features and other issues are discussed.
