Reticulum-cell sarcoma with primary manifestation in the testis.Report of four cases

HE APPEARANCE of reticulum-cell sarcoma T in the guise of a primary testicular tumor has been rarely encountered. Although more than 2860 cases of testicular tumor have been reported in English-language literaturel-496-8, *O-I2, 14-26,28129 i n the past ten years, only six03 8,163 259 29 of these were reticulum-cell sarcomas. Stout has seen five such cases of this tumor arising in the testicle, of which one has been reported.16 I n a group of 158 testicular cancers reported by the present authors,l3 two were of the reticulum-cell-sarcoma type. Since then, we have observed two additional cases in seventy-five more testicular tumors treated in our Radiotherapy Department. T h a t testicular involvement is not common even in patients dying of generaIized reticulum-cell sarcoma is evident from the fact that only three of fortyseven cases were found to have testicular involvement at postmortem.
