[Granulocytic sarcoma of the testis without hematological manifestations].

A 30-year-old man with a testicular tumor ressembling a "round cell sarcoma" was treated for rhabdomyosarcoma. Complete remission was achieved but the patient relapsed and died of the disease. A retrospective diagnosis of granulocytic sarcoma was established using an anti-myeloperoxidase antibody, unfortunately not available at the time of the initial diagnosis. No hematological disorders were observed during the course of the disease. Four cases of granulocytic sarcoma of the testis have been reported in the literature. All these cases where accompanied or followed by leukemia. The present case seems to be the first case of granulocytic sarcoma of the testis not accompanied by hematological disorders.
