THE SCARCITY of available critical literature on the specific character of primary retroperitoneal tumors and the prevailing impression of their infrequent occurrence have thrust into undeserved obscurity a subject of considerable medical significance. The inordinately high incidence of preoperative diagnostic failures generally reported necessitates more widespread cognizance of these tumors than has previously been accorded them, since inaccuracies in diagnosis engender misleading therapeutic implications. Although the subject is considered of special interest to the urologist, because a large proportion of retroperitoneal tumors by the very nature of their close relationship to the kidney and ureter may cause urinary complications, the surgeon and gynecologist are on occasion confronted by such masses when they simulate tumors of the abdominal cavity or of the genital tract.
