6. 61. Bony Outgrowths on the Tibia and Fibula associated 

 with Chronic Ulcer of the Leg. — Left tibia and fibula — 



macerated, showing the above. 



The patient was a man aged 64. At the age of 42, the skin of his 

 leg had been extensively burned at the upper and outer parts. The 

 wound had healed, but the scar had broken down seven years before his 

 ■admission to the Infirmary, and had formed a large ulcer on the upper and 

 outer part of the leg. This ulcer had remained open, and latterly had 

 become epitheliomatus at the upper part. The leg was amputated on 

 account of the epithelioma. 



Both bones, but especially the fibula, show considerable 

 thickening and new periosteal formation. The surface of the 

 fibula is covered with irregular stalactite processes, which to a 

 certain extent follow the line of attachment of the interosseous 

 membrane and of the inter-muscular septa ; but there is also 

 considerable thickening on the subcutaneous area above the 

 outer malleolus. 



The portions of the tibia most affected are the oblique and 

 interosseous ridges, and the upper part of the extensor surface. 

 At these places the surface of the bone is covered with irregular 

 processes similar to those seen on the fibula. The articular 

 surfaces of the knee and ankle are comparatively unaltered.

6. 62. Chronic Ulcer of the Leg which caused the Bony 

 Outgrowths in the foregoing Specimen.— Cast — in glue 

 and glycerine — of the ulcer which was present before amputa- 

 tion in the previous case. 



The irregular warty portion at the upper part is where 

 the epithelioma had begun. The rest of the ulcer was 

 covered with granulations, and the surrounding skin was 

 cicatricial. G. C. 3195.
