Abstract
|
|
|
A case of chondrosarcoma on the proximal portion of the right humerus is reported. The patient is a 42 year old male who has had a hard mass over the right upper arm for 13 years. About 13 years prior to admission, the patient began to notice a. hard mass on the proximal portion of the right humerus and thereafter it had gradually grown to adult fist size. However the size of the mass had been stationary untilt three years prior to admission and then it showed a rather rapidly growing tendency,. and on the admission it had reached child head size.
Roentgenological study revealed a large mass with cauliflower like irregularly calcif ied density on the lateral aspect of the proximal half of the right humerus.
En block excision was performed as the patient strongly refused to have forequarter amputation. The mass measured 25cmX25cmX2Ocm in size. Most of the lesion was composed of a graish white substance and small patchily calcified areas of cartilaginous_ matrix.
The clinical course, roentgenographic findings, surgical findings and pathological study confirmed it to be a typical secondary and peripheral type of chondrosarcoma originated from osteochondroma.
The recent follow up 29 months after operation revealed no evidence of recurrence and, the- patient was in his good health.
