SARCOMA.—Of the 36 cases of sarcoma, of various types and in different situations, which enter into our list of malignant neoplasms, very few can be mentioned as illustrations of the value of dietary and medicinal treatment; many of them were seen only in consultation, or once or twice, and it is very difficult for those afflicted with such affections to be persuaded of the value of prolonged internal treatment when surgery apparently offers such brilliant immediate results. But there is one patient with sarcoma of the upper jaw, whom you saw a while ago in an ulcerative condition, with a great hole in the cheek and a cavern within, whose improvement is so phenomenal that I now present her to you again to-day, as she is about to leave the hospital, after a little over four months’ stay. _Case IX._—Miss R. L., aged 19, entered the New York Skin and Cancer Hospital, in my service, July 24th, 1916, weighing 89½ pounds. She had formerly weighed 120. About three years ago a small lump developed beneath a pigmented mole which had long existed, an inch or so below the right eye. This grew rapidly until it was about an inch in diameter, and was movable and painless. About January 1st a tooth in the right upper jaw became loose and three teeth were extracted; a radiograph was taken, and she was advised hospital treatment. She then entered another hospital and the gum was incised and radium applied for 18 hours on March 1, 1916. After this operation the face became swollen and very painful, and an extensive operation was performed in May, the right upper maxilla being removed, together with the tumor. Four weeks before entering the New York Skin and Cancer Hospital a pin hole opening was noticed in the scar on the cheek, which increased in size up to the time of admission. She remained in that hospital until she came to us. The microscopic examination of the portions removed showed the disease to be sarcoma. On entering the hospital there was an opening in the right cheek something over an inch in diameter with ulcerated edges, and a cavity extending down to the tongue, the superior maxilla having been removed surgically. From the upper margin of the opening there was a mass of dead bone hanging, nearly three quarters of an inch long by half an inch wide. The interior of the cavity presented a mass of ulceration, giving forth a foul odor. She was thin, pale, and anemic with 85 per cent hemoglobin and 3,620,000 red blood corpuscles.
