概要: We analysed the histological features of various kinds of infectious colitis, using biopsy specimens from 77 cases of in fectious colitis. We concluded 7 kinds of colitis induced by pathogenic organs―Cytomegalovirus colitis, Amebic dysentery, Clostridium difficile colitis, Yersinia colitis, Escherichia coli O157:H7 associated colitis, Typhoid fever, and Anisakiasis―could be diagnosed or suspected only by their histological features. Among them, Staphylococcus associated colitis, Bacillary dysentery, Salmonella colitis, Campylobacter colitis, and Enteropathogenic E. colli except E. coli O157:H7 associated colitis associated colitis, and Vibrio paraheamolyticus enterocolitis show non-specific acute inflammation;infiltration of neutrophils and chronic inflammatory cells. And the histologic transition of these colitis is neutrophilic predominant infiltration on day 1 to day 3, lymphoid cells and plasma cells predominant infiltration on day 4 to day 7, and decrease of inflammation cells after day 8. And we also compared the histological features of infectious colitis with that of ulcerative colitis. We listed seven features highly characteristic of ulcerative colitis and rarely seen infectious colitis. 続きを見る

概要: We report a case of adenomatoid odontogenic tumor in the maxillary bone. The patient was an 11-year-old girl who complai ned of cheek swelling. X-ray examination revealed that the tumor involved an impacted canine in its cystic lesion and occupied most of the space of left maxillary sinus, and contained microcalcifications. The lesion was extirpated under general anesthesia and examined histopathologically, to be diagnosed as adenomatoid odontogenic tumor. On histologic examination, it showed characteristic duct-like structures and whorled or rosette masses of tumor cells. The rim and amorphous contents of duct-like structures and eosinophilic droplets among solid nests of columnar cells were much of eosinophilic and argyrophilic materials. In immunohistochemical staining, they also showed strong immunoreactivity for heparan sulfate proteoglycan, laminin, and collagen type IV.<br />11歳、女児に認められた腺様歯原性腫瘍の1症例を報告する。主訴は頬部の腫脹で、Ⅹ線診査で左側上顎洞部に埋伏犬歯と小石灰化物を含む嚢胞様病変を認めた。全身麻酔下、病変を摘出し、病理組織学的検索を行った。腺様歯原性腫瘍の病理診断が得られ、特徴的な管腔様構造と塊状胞巣を認めた。管腔様構造内面の縁取りと内部の無定型内容物及び充実性胞巣内滴状物は好酸性及び好銀性多糖類に富み、また、免疫染色ではヘパラン硫酸プロテオグリカン、ラミニン、Ⅳ型コラゲンに強陽性であった。 続きを見る
