Abstract

Clear cell chondrosarcoma is a very rare malignant bone tumor that shows a strong predilection for the epiphysis or metaphysis of long bones. Many studies have reported that the proximal end of the femur is the most commonly affected site, followed by the proximal end of the humerus. Histopathologically, tumor cells of this type have centrally located round nucleoli with clear cytoplasm and a distinct cytoplasmic membrane. Generally, clear cell chondrosarcomas is not confused with conventional chondrosarcomas. However, when it involves the diaphysis in long bones, diagnosis can be hindered, as only three reports of this exist in the literature. We report herein an unusual case of clear cell chondrosarcoma of the tibial diaphysis in a 42-year-old male.

투명세포연골육종은 매우 드문 골종양으로 장골의 골단이나 골간단에 발생한다. 많은 연구에서 대퇴골의 근위부를 가장 흔하게 발생하는 부위로 보고하였고, 상완골의 근위부가 그 다음으로많이 보고되었다. 조직학적으로 이 종류의 종양 세포들은 투명한 세포질과 뚜렷한 세포질막과 함께 중심성으로 위치하는 둥근 핵소체를 가지고 있다. 일반적으로 투명세포연골육종은 고식적인 연골육종과 혼동되지 않는다. 하지만, 방사선학적으로 장골의 간부에 발생한 경우 진단이 어려우며, 이전 문헌을 통하여 단 3례만이 보고된 바 있다. 저자들은 이전에 보고된 바 없는 42세 남자 환자의 경골 간부에서 발생된 투명세포연골육종을 보고하고자 한다.
