喀血または血痰を訴えて来院する患者については,結核症がその大多数を占め,気管支拡張症,肺腫瘍,気管支炎,肺膿瘍などが,これに次ぐ事は臨床上経験し,また文献の報告にも見られるところである。殊に近年気管支鏡の発達に伴い各種疾患に対する診断的価値は増加し,重要な役割を果している。われわれは約1年にわたり血痰を訴えた1患者について,気管支鏡検査,各種レ線写真,喀痰検査および経過などから,結核症,気管支拡張症および偶発性気管出血などを疑わしめ,診断困難であつた肺吸虫症の1例を経験したので報告する。
Saito and associates report a case of pul-monary parasitosis that caused a considerable difficulty in arriving at a diagnosis. The only complaint that the patient, a man aged 20, made was that of being affected with bloody sputum. Various conditions that may provoke such a sign like pulmonary tubercu-losis, bronchiolectasis and spontaneous tra-cheal hemorrhage were supected but all tests pertaining to them proved to be negative. What lead the effort in diagnosis still further astray was the negative finding of parasitic ova in the sputum. Two months later the sputum test for ova was repeated; the diag-nosis was finally established by this repeated examination. The authors emphasize the ne-cessity of making repeated laboratory tests when cases are met with that present diag-nostic difficulties.
