[Differential diagnosis of infiltrative tuberculosis and pneumonia located in the the lower lobe].

Differential diagnosis was made in 2 groups of 85 patients with infiltrative tuberculosis and pneumonia. Clinical, laboratory and x-ray findings confirmed the value of standard examinations (anamnesis, complaints, physical and laboratory methods). Tuberculin diagnosis confirms the primary diagnosis only in case of hyperergic response to the Mantoux test with tuberculin PPD 2 TU.
