[Chondrosarcoma of the hyoid bone. Follow-up and cytological study of a case].Pathologica. 1992 Mar-Apr; 84(1090):235-41.P
The follow-up study of one chondrosarcoma of the hyoid bone is reported; the tumor was a well differentiated grade II chondrosarcoma that relapsed after 10 months and metastasized after 6 years. Fine needle aspiration cytologic method was utilized for the diagnosis of the lung metastases. Cytologic criteria in the differential diagnosis of the chondrosarcoma are discussed. Follow-up of the extra-skeleton chondrosarcoma has to be continued for a long time independently from the grade of differentiation.
