6. 356. Chondroma of the Humerus. — Glycerine and gelatine 

 cast of same tumour as it was after removal. 



The relation of the tumour to the arm is well brought out, 

 as well as the nodular character of the surface of the tumour,

after the operation, of the patient from whom the foregoing 

 tumour was removed. Taken from Mr Chavasse's paper. (See

6. 358. Chondroma of the Humerus. — Wax cast of a left 



humerus and attached tumour, illustrating the above. 



Six years before the operation the patient had occasional pains in the 

 shoulder, and in six months afterwards he observed ou the forepart of 

 the shoulder a firm swelling, which appeared to be seated on the bone. 

 Three years afterwards he fell and broke the affected humerus about the 

 middle, but it united without displacement. "But the morbid growth 

 advanced more rapidly after this injury, and his uneasy sensations kept 

 pace with its progress. He said that what chiefly distressed him latterly 

 was a feeling of weight and oppression which never ceased, and was 

 particularly severe during the night. He had no other complaint, and 

 seemed to be sound in all other respects." 



Before the operation the following description was drawn up : — " It 

 had a verj- broad base, which completely filled the axilla, and seemed to 

 grow out from the side of the thorax. The shoulder-joint did not admit of 

 any motion, but the arm moved freely along with the scapula. The head 

 of the humerus seemed to be the centre of the swelling, which extended 

 from it in every direction, terminating about half-way from the elbow, 

 and approaching within two inches of the sternum. The clavicle and 

 spine of the scapula could be traced nearly, but not quite, to their 

 junction. The consistence of the tumour was extremely firm, feeling in 

 some parts as if it were composed of bone, and in others of fibro-cartilage. 

 The surface appeared in general pretty equal, but when examined more 

 carefully was found to be irregularly nodulated. The colour of the 

 integuments was not altered." 



The tumour was removed, along with the glenoid cavity and the
