[Lower lung field tuberculosis].
Lower lung field tuberculosis has been considered as rare disease, but it was observed about ten percent in the literature. It seemed that the important problems in lower lung field tuberculosis are delay and difficulty of diagnosis. The materials for this report was accumulated over a period of 10 years, from January 1983 to December 1992 at the National Sanatorium Fukuoka-Higashi Hospital. The criteria for lower lung field tuberculosis are: (1) disease confined to lower lobe except for S6a, middle lobe and lingular segment, (2) bacteriologically and/or histologically proved diagnosis of tuberculosis, (3) clinically considered as tuberculosis for which improved by only anti-tuberculous drugs. During this period, 672 new patients suffering from active pulmonary tuberculosis were admitted to the sanatorium. Of the total of 672 patients, 57 patients were selected as the criteria for lower lung field tuberculosis. The incidence of them was 8.5 percent of the total new admissions. Of these 57 patients, 30 were females and 27 males. The mean age of these 57 patients was 59.4 years ranging between 19 and 86 years. The incidence of them obtained through ten years did not show any tendency to increase or decrease. The respiratory and general symtoms most commonly observed were cough and chest pain. The average duration of used for diagnosis of the lower lung field tuberculosis over 65 years old was 71.7 days and it seemed to show the delay and difficulty of diagnosis.
