ENCHONDROMA “ A CASE REPORT “

INTRODUCTION: We present a case of patellar and capsule-synovial
chondrosarcoma associated with distal femoral enchondroma, who finally undergo to
high thigh amputation. CASE REPPORT: A woman 37 years old presented in our
Clinic for right anterior knee pain, swelling and decreased range of motion for more
than 10 months.Biopsy was undertaken, in the condition of multiple surgery around
the knee in the past. The histo-pathological result was enchondroma of the femur
and uncertain for the patella. As the right knee continue to be extremely tender to
palpation in the region of the patella and knee bending was restricted secondary
pain, we decided to undertake patelectomy and muscle tendon transfer, sinovectomy
and distal femoral biopsy once again. The microscopic result concluded patellar and
capsule synovial chondrosarcoma moderate differentiated grade G2 associated with
distal femoral encondroma. After surgery, the patient felt well and was transferred to
an Oncologic Clinic to continue the chemotherapic treatment and finally high thigh
amputation was decided in a medical team consulting and performed. At one year
the patient feels good and had returned to daily homework thanks to external limb
prosthesis. DISSCUSIONS: A Medline search and the research of specialty literature,
as far as we could get information on the topic, did not yield any previous report of
such an association between distal femoral enchondroma and patellar and capsulesynovial
extension chondrosarcoma. Radiological diagnosis of different patella
tumors is challenging and anatomo-pathological analyses may be difficult, but certain
in results when bone biopsy is well performed.
