“…The most common sites of these lesions are the hip-joint (e.g., Brill and others, 1905;Todd and Keidan, 1952;Vaughan-Jackson, 1952;Wood, 1952), the mandibular joint (Cecil, 1948;Snapper, 1943), and the knees (Draznin and Singer, 1948;James, 1952;Kroboth and Johnson, 1952;Markovits, 1949;Pick, 1927), including the lower part of the shaft of the femur with its typical flask-like deformity (Davies, 1952;Windholz and Foster, 1948). Affections of the shoulder bones seem to be less frequent; Pick (1927), reviewing the literature as a pathologist and adding four cases of his own, does not mention involvement of the upper extremity except in the case described by Brill and others (1905).…”
