所謂淋巴管内被細胞腫の1例に就て

　緒言

　内被細胞腫は発生母地が，淋巴管か，血管かに依つて，淋巴管内被細胞腫及び血管内被細胞腫との2種に区別され，両者の頻度は内外の文献共に淋巴管内被細胞腫の方が多い樣である．A. Denkerは更に血管内被細胞腫を血管周囲型と血管内型とに別けている．

　淋巴管内被細胞腫は肉眼的には緻密な，結節状，或は粘液樣，髓樣の性質を持つている．淋巴管内被細胞腫の文献は多々見られ，殊に我が耳鼻咽喉科の領域に於ては，比較的屡々遭遇する腫瘍であり，殊に口蓋に其の50％以上の発生率を示す爲，口腔外科方面に於ても散見せられるものである．

　Nonaka and Niho report a case of lymphangioendothelioma and discuss its symptoms, age incidence, diagnosis and method of treatment. A child 3 years of age, which was accompanied by its mother sought relief from a swelling that was present in the nasal vestibule. The previous examiner believing the swelling to be a furunculosis made an attempt for incision and drainage; since which, a rapid increase in its size occurred. Present examination revealed the growth as having its origin in the left malar region and moreover, proved it to be a lymphangioendothelioma. Surgical removal of the tumor was later supplemented by irradiations and the together of which accomplished a complete cure of the patient without further complications. It is interesting to note, from statistical view point, that such growths have a greater tendency to occur on left side of face rather than the right.
