深部真菌病近30年来发病日渐增多,且诊断困难,治疗棘手。本文就深部真菌病的真菌学、发病机理及病理变化等作一简要叙述并着重复习胃真菌病的有关文献,以供病理同道参考。真菌的一般形态真菌为单细胞或多细胞低等植物,其基本结构为菌丝及孢子。不同真菌具有不同菌丝及孢子,是真菌分类的依据。菌丝为细微管状结构,具有孢壁、孢浆和孢核,粗细不等,一般直径不超过10微米,分枝或不分枝,可有横隔或无横隔真菌的繁殖方式分有性及无性两种,大多数病原性真菌都是无性生殖。无性孢子有三类即叶状孢子,分生孢子及孢子囊孢子。叶状孢子又包括芽生孢子,厚壁孢子及关节孢子;芽生孢子系细胞出芽生或成熟后,芽孢脱离母孢子单独成为一个新生个体, Deep mycosis in the past 30 years the incidence of increasing, and the diagnosis difficult to treat difficult. In this paper, mycology of deep fungal diseases, pathogenesis and pathological changes for a brief description and focus on the review of the literature on gastric fungal disease for pathological fellow reference. The fungal form of the general form of single-cell or multicellular lower plants, the basic structure of mycelium and spores. Different fungi have different mycelium and spores, is the basis for the classification of fungi. Mycelium is a fine tube-shaped structure with spores, spores and spores, ranging in thickness, generally not more than 10 microns in diameter, branched or unbranched, with or without transversal septum fungal reproduction of sexual And asexual two, most of the pathogenic fungi are asexual reproduction. There are three types of asexual spores conidia, conidia and sporocyst spores. Spore-like spores also include spore germination, thick-walled spores and joint spores; spore germination of germinal cells or mature spore spores from sporozoites to become a single newborn individuals,
