Description
The testis is very markedly expanded by a semi-cystic tumour, showing areas of necrosis and
haemorrhage. The surviving testicular tissue can be seen at several points at the periphery.
History
This man presented at the age of 28 with a six-month history of increasing swelling in
the right testis. The testis was removed and is described as weighing 634 g. This histology is that
of a malignant teratoma, intermediate. No tumour was found in the cord. He was subsequently
found to have secondary deposits in the abdominal lymph nodes; these were removed and shown
to contain tumour; he was later treated with irradiation and chemotherapy. One year later, he is
alive and well.
