Longitudinalsection through gross specimenshowing expansion of tumor downshaft, central area of destructionin tumor and perforation of cor-tex. Tissue in gross was white,opaque and gelatinous, suggestingmyxoma. tation (Fig. 17), near the headof humerus, and for this reasonresection w as advised without ex-ploratory incision. The opera-tion (Major Kirk) was a dis-articulation of the right shoulder,with resection of the humerus atthe junction of the upper andmiddle third. Tumor tissue wasnot exposed during disarticula-tion, but when the biceps tendonwas dislocated from its groove,clear serum exuded, suggestingperforation of the cortex. Thewound was thoroughly spongedwith alcohol. When the humeruswas resected a small particle oftumor tissue was seen in the mar-row cavity, and frozen section Page Fourteen showed definite evidence of ma-lignancy. Immediately this wassponged with alcohol and thehumerus resected above the con-dyles. I lere the bone and mar-row appeared no
