AimsThe incidence, presentation and macroscopic and histological features of secondary neoplasms of the male genital tract are described with reference to their differential diagnosis.Methods and resultsA retrospective study of cases from the Royal London Hospital yielded a total of 31 secondary neoplasms involving the testis: 14 at postmortem examination and 17 surgical specimens. Nine cases were leukaemias: six acute lymphoblastic and two acute myeloid leukaemias in children, and one chronic lymphocytic leukaemia in an adult. The commonest primary sites of metastases to the testis were prostate (six cases), stomach (five cases) and lung (three cases). There were two malignant melanomas and isolated examples of metastases from the adrenal gland (neuroblastoma), cerebellum (medulloblastoma), soft tissue (alveolar rhabdomyosarcoma), pancreas and rectum. Of the metastases from solid tumours, 12 involved the right testis only, three involved the left and four were bilateral. In seven of these cases there were multiple testicular nodules, in seven there was a single mass, and in the rest there was diffuse involvement. Secondary neoplasms represented 4.6% of all testicular neoplasms at autopsy, and 1.6% in surgical specimens. There were five secondary penile neoplasms: two each from the pancreas and prostate and one from the bladder. Two neoplasms metastatic to the spermatic cord, both from a gastric primary, were included in the series.ConclusionsSecondary neoplasms of the testis occur with a frequency comparable to other sites in the genitourinary tract, and metastases to the spermatic cord, epididymis, and penis, are rare in comparison. Disseminated neoplasms rarely present initially at this site and are histologically distinctive in adults, but in children they must be distinguished from primary small round blue cell tumours.
