title: [Tuberculous hilar lymphadenopathy: a survey of recent cases. Study of the variations in clinical manifestations and the mode of onset].
abstract: Forty-eight cases of tuberculous hilar lymphadenopathy were studied comparatively between the groups experienced before and after 1975. We found the following characteristics in the clinical manifestations and in the mode of onset among the recent cases as against the classical ones. (1) Age distribution of cases shifted from younger to elderly groups. (2) Roentgenologically, typical primary complex has been decreasing, while the atypical patterns such as solitary mediastinal lymphadenopathy or those associated with healed pulmonary lesions have increased. (3) Since the introduction of RFP to the treatment of tuberculosis, cases of hilar lymphadenopathy incidentally diagnosed with the early exacerbation due to RFP has been increasing. (4) Of the total of 48 cases, 10 were presumed not being originated from the primary infection, but from reactivation. (5) Relative increase of such cases may partly explain the shift of hilar lymphadenopathy to elderly group.
