Giant cell tumours of bones are uncommon and are usually found in the epiph
yses of long bones. They are rare in flat bones (<10%), The tumour has to o
ur knowledge never been described in the hyoid bone, although 18 cases have
been reported in the cartilagenous laryngeal skeleton, We report a giant c
ell tumour of the hyoid bone in a 45-year-old man, which we excised along w
ith the left half of the hyoid bone. It recurred locally one year later and
was cured by excision and split course radiotherapy. The patient is diseas
e-free after 30 months of follow-up, (C) 2000 The British Association of Or
