The purpose of this paper is to review the experiences of admitting cases with Atypical mycobacterial disease at the national tuberculosis sanatorium. The authors presented nine cases of the disease, and the results of bacteriological and clinical findings were reviewed. During the past fifteen years nine cases of Atypical mycobacterial disease were hospitalized, two of which were the cases of scotochromogens and the remaining seven were of nonphotochromogens. Atypical mycobacterial disease was thought to be a rather rare disease in the authors' district. The characteristics of the colonies of each strain were distinctive under a low magnification microscope. Photographs of them were presented. Roentgenographic findings in each ca s e was not distinguishable from those in pulmonary tuberculosis, because of the wide varieties of the latter. Nevertheless it was likely that in the cases of Atypical mycobacterial disease the perifocal inflammation and the subsequent residual fibrotic constriction were milder, and the trend for inspissation of cavitary lesion was not seen, and none of the cases showed a large nodular lesion. In some cases it was suggested that some kinds of damage in the lung such as pulmonary fibrosis, bronchiectasis, or cystic lesion was the provoking factor of the disease. Through the hospitalization period of the patients in a room with pulmonary tuberculosis patienst, there was no evidence of infection between each other, and the sputum converted to negative after variable duration of time.
