Abstract

Bone. Localization of the sarcoid lesions in bone has frequently been described, but the true incidence of such involvement is not known. The incidence of roentgenographically demonstrable involvement, however, has ranged between 15 and 25 per cent of cases in several series^{5, 38, 49, 131}; in others it has been considerably lower,^{45, 132} and only 1 case of such involvement has been reported from Australia.¹¹⁸ The tendency of the lesions to appear at any time, to last for indefinite periods, to regress spontaneously and even to reappear at a later date⁴⁴ makes it necessary to follow cases for an adequate period by . . .
