title: Extrapulmonary tuberculosis: are statistical reports accurate?
abstract: Before discussing the epidemiology of extrapulmonary tuberculosis (EPTB) and particularly urogenital tuberculosis (UGTB), unification of the terminology is necessary. The term 'urogenital tuberculosis' is preferable to 'genitourinary tuberculosis', as renal and urinary tract tuberculosis is more common than genital tuberculosis. Some understand the term 'extrapulmonary tuberculosis' as a specific tuberculosis (TB) lesion of all organs excluding the bronchus, lungs, pleura and intrathoracic bronchopulmonary lymph nodes, but others consider pleural TB as one form of EPTB - and it is a reason for very different proportions in the spectrum of EPTB. Enigmatic tendencies have also been revealed in patients' distribution - in neighbouring regions the incidence rate may differ significantly. Although there is no clear explanation for these tendencies, careful study of the epidemiology of EPTB in different conditions will improve early diagnosis.
