376 Diseases of Bone. 



4th April Mr Duncan amputated the leg at the knee-joint, and the 

 patient made a good recovery. 



In most parts the marginal bone has been reduced to a 

 mere shell. Below and near the outer tuberosity the tumour 

 substance is invading the healthy-looking bone, but with very 

 little infiltration. 



When fresh, the tumour had the characteristic appearance of 

 a myeloid sarcoma. At one spot, i.e. below the crucial liga- 

 ments, there was some greyish sarcomatous-looking substance, 

 but all the rest was like blood-clot, crimson, orange, and yellow 

 in colour, as if in varying stages of decolorisation. These 

 appearances are now much altered by the action of the spirit. 



The blow had evidently broken the fibula, and seems to have 

 splintered the tibia. G. C. 3174

Mrs T. , aged 62, was admitted to Chalmers Hospital in October 

 1890. She had been healthy until the present tumour began, about ten 

 years before. The first symptom was pain over the head of the right 

 fibula. This was followed by swelling in the neighbourhood, which 

 increased gradually at first, but rapidly for the last twelve months. On 

 admission the tumour surrounded the leg completely in its upper two- 

 thirds. The maximum circumference of the tumour was twenty-two 

 inches. The skin over it was tense, and the veins were dilated. To the 

 touch it felt mostly firm and fibrous ; it was fluctuating and apparently 

 cystic in places, with a few calcareous masses perceptible in the walls of 

 the cysts. Amputation was performed through the lower third of the 

 thigh in October 1890, and the patient made a good recovery.
