[Aspiration biopsy cytology in malignant tumors of the testis? (author's transl)].

Fine-needle aspirates and tissue prints of 23 malignant tumors of the testis were obtained after surgery. In all cases malignancy was recognized by cytological examination. Only in two cases there was a discrepancy between cytological and histological classification. Malignant teratoma undifferentiated (MTU) was cytologically diagnosed in two cases verified as malignant teratoma intermediate (MTI) by histology. The value of fine-needle biopsy in diagnosis of malignant tumors of the testis is discussed.
