title: [Laryngeal tuberculosis: considerations on the most recent clinical and epidemiological data and presentation of a case report].
abstract: According to the "Global Tuberculosis Control" performed in 1999--the third complete, international, global report on tuberculosis infection--173 countries reported their infection data to the WHO; of these countries 102 met the criteria for "DOTS programs" at the end of 1997. The DOTS programs are the only control strategy able to produce a cure rate of 85%. Both at the national and international (Centers of Disease Control) levels, guidelines have been drawn up to improve and coordinate the fight against tuberculosis. New indicators and methods of analysis should be developed to quantify the full impact on the control of infection transmission, incidence, prevalence, mortality and prevention of drug resistance. In addition, two significant world-wide events have affected the increase morbidity rate seen in the last decade in the more highly industrial countries: immigration from countries outside the European Community and HIV infection. The tuberculosis infection worsens the evolution of HIV, facilitating viral replication. In the present work the authors discuss the most recent epidemiological data regarding tuberculosis infection and review the Literature on the primary laryngeal location of the disease. Then they present a clinical case which recently came under observation. This case is a typical example of the clinical picture of the laryngeal tuberculosis seen today. It must not be forgotten that in recent years there has been an increase in morbidity in Italy, in both the pulmonary and extrapulmonary forms of the disease, although in our country the problem of delayed or incomplete reporting is quite widespread. The data show that the age ranges with the highest incidence of both pulmonary and extrapulmonary forms are the 25-35 and 60-70 year groups. Distribution by sex, on the hand, shows that the pulmonary forms are most often seen in males while the extrapulmonary forms have practical the same frequency in both sexes. In recent years the clinical and morphological aspects of tubercular laryngitis have changed significantly from what they were before chemotherapy and the most common clinical form is pseudotumoral tuberculosis. This form requires a differential diagnosis to distinguish it from neoplasms because they present a similar objective picture and have no signs of simultaneous or previous pulmonary involvement.
