ABSTRACT
In a review of all tumours and tumour like lesions of the craniofacial bones between the years 1963 and 1980, 19 cases were diagnosed as fibro osseous lesions. The mean age of occurrence was 23.8 years with a slight male predominance (1.6:1). The clinical and histological aspects of the various lesions, the problems in diagnosis and the impact of diagnosis on clinical behaviour are discussed.

Fourteen histologically proved specimens of clear cell sarcomas (CCS) of tendon sheaths were studied for the presence of S-100 protein. Eleven cases were strongly positive, and 2 cases were weakly positive. There was only one case which was absolutely negative for this protein. This technique was useful to diagnose tumours which were not only easily diagnosed as CCS or soft tissue melanomas, but also in the atypical and spindle cell variants of CCS which have to be weeded out of the large family of other morphologically allied soft tissue tumours.
