386 Diseases of Bone. 



Above the condyle the interior is rarefied in some places 

 and condensed in others. The surface of this affected part is 

 somewhat rarefied, while above and below the rarefied area 

 there is a crust of new periosteal bone. G. C. 984. 



6/453. Sarcoma in the Stump of a Femur, after 



Amputation. — Portion of a femur — in spirit, illustrating 

 the above. 



The patient was a marine, in wliom a very large tumour, 23 

 inches in circumference, had grown from the upper part of his left 

 leg, between the 5th Jlay, when his leg was jammed, and the end of 

 September, when the note was taken. 



The leg was amputated on the 5th October, and he died on the 

 eleventh day after of tetanus, the stump, however, having been very 

 unhealthy, with frequent secondary lipemorrhage, for several days before. 

 The tumour had apparently been a sarcoma of the most malignant kind 

 growing from the upper part of the fibula. 



There is a large fungous projection of tumour substance from 

 the lower end of the medulla, i.e. where the bone was divided 

 at the amputation ; while the medulla at the other end is seen 

 to be full of the same material. (See case of Robert Lane, 

 Bell's " Surgical Eej)orts and Observations," p. 386.)

SARCOMA FOLLOWING FRACTURE. 



6. 454. Central Sarcoma of the Femur, following- Frac- 

 ture. — Section of the broken ends of the right femur of a man 

 aged 4.5 — in spirit, illustrating the above. 



" This man Is of middle stature, muscular, but not fat ; his visage 

 is particularly thin, and it has a foul yellowish colour ; he has dark eyes 

 and black hair. 



" About nine months ago he broke his thigh-bone. The bone was 

 knit together ; he fell and broke it a second time at the same place. 

 After the usual period of confinement, the bone being united, a tumour 

 rose gradually in the very centre of the thigh. It was attended with 

 great pain. It has uniformly and imperceptibly increased, imtil now that 

 it forms a tumour measuring three times the circle of the natural thigh.
