恶性组织细胞病(简称恶组)是单核一巨噬细胞系统中的组织细胞恶性增生性疾病。本病于1939年为Scott和Robb—Smith氏首先报导。国内1957年田氏和1960年郁氏相继报导以后,各地陆续有不少报告,迄今已约千例。由于本病起病急、进展快、表现多样而常常误诊,如张凤声氏的33例中有21例入院时误诊,误诊率达63.9％;张龄等的52例误诊39例,误诊率75％;本组34例中入院第一诊断错误者25例,误诊率73.5％。为了总结经验,提高对本病的认识,把我院自1970年7月～1983年12月住院病例中资料较全的34例进行临床分析。本组25例是通过血和骨髓涂片确诊,8例通过淋巴结或皮肤活检确诊,另1例为死 Malignant histiocytosis (referred to as evil group) is a malignant proliferation of tissue cells in the monocyte-macrophage system. This disease was first reported by Scott and Robb-Smith in 1939. Since Tian’s 1957 and 1960’s Yu’s reports have been reported in succession, many reports have been made in various places, with about one thousand cases so far. Because of the rapid onset of disease, rapid progress, performance and often misdiagnosed, such as Zhang Fengsheng’s 33 cases, 21 cases were misdiagnosed at admission, misdiagnosis rate of 63.9%; Zhang et al 52 cases of misdiagnosis in 39 cases, misdiagnosis rate of 75% ; The first group of 34 patients admitted to hospital the first 25 cases of diagnostic errors, misdiagnosis rate was 73.5%. In order to summarize the experience and improve understanding of the disease, our hospital from July 1970 to December 1983 hospitalized patients with more data in 34 cases for clinical analysis. The group of 25 cases were diagnosed by blood and bone marrow smears, 8 cases were diagnosed by lymph node or skin biopsy, the other one was dead
