Pseudo –“solid pseudopapillary neoplasms” of the testis: in reality Sertoli cell tumors

We read with interest and concern two reports published in Human Pathology [1,2] concerning testicular neoplasms that were felt to be “testicular analogues” of the well-known “solid pseudopapillary neoplasm” (SPN) of the pancreas, albeit in one of the 2 papers the authors preferred to designate the tumors as primary signet ring stromal tumors of the testis [1]. Although we acknowledge that the pseudopapillae in the SPNs ma y be limited in amount, their apparent absence, according to the descriptions of the microscopic findings in all of the 14 tumors in these 2 reports, struck us as unusual for a tumor the authors were placing in the SPN category.
