TUBERCULOSIS OF PHARYNX.

It is a strange fact that although pulmonary tuberculosis carries off more of the human race than any other disease, its local manifestations in the upper respiratory tract occur with comparative infrequency. The larynx is much more often affected than the pharynx. In 1226 cases of tuberculosis, Heinze found the larynx involved in 276 or 30.6 per cent. Mackenzie, in 100 cases in the second and third stages, found changes in the larynx in 71. Tuberculosis of the pharynx must be regarded as an extremely rare condition. Lennox Browne12 states that acute tuberculous sore throat occurs in about 1 per cent. of all cases of tuberculosis of the upper air-passages. This percentage, according to the censensus of opinion, is if anything too large. Willigk, in 1307 autopsies, found only 1 case of pharyngeal tuberculosis.
