IV. TUMOUKS OF BONE. 



A. Cartilaginous Tumours — ranging from the sloivly-groiving- 

 sijRjjle forms ivJiosc tissues are ivell clevelo2)ed, to the raindly- 

 gr owing malignant forms whose tissues are more or less- 

 embryonic. 



6. 354. Chondroma of the Humerus. — Section of a righ 

 humerus and of a cartilaginous tumour growing from it — in 

 spirit. 



The patient, a man aged 40, had noticed the tumour growing 

 below and external to the shoulder-joint for ten years before he consulted 

 Mr Chavasse. It had grown steadily, and by its increase liad caused pain 

 in his neck and forearm. During the last eighteen months the growth 

 had been more rapid, and the surface had become irregular. Three 

 months before the operation, softened patches had appeared at tlie lower 

 part. One of these had given way, and an oily fluid had at first drained 

 from it, but shortly before the operation free h?emorrhage, apparently 

 venous, had occurred from it also. " Up to the last the affected arm, 

 with the aid of a sling, was used for driving, and there was no deteriora- 

 tion of the patient's general health." 



The upper limb, including the scapula and part of the clavicle, 

 was removed by Mr Chavasse, according to Berger's method. The patient 

 made an excellent recovery, and some years afterwards was known to be 

 in excellent health.
