A 36-year-old male patient is described who presented with gynaecomast
ia, pulmonary nodules and a retroperitoneal mass in combination with a
markedly elevated HCG level. A diagnosis of ''choriocarcinoma syndrom
e'' was made. Despite a clear response from the tumour to chemotherapy
the patient died, at least partially due to delay in treatment. Promp
t treatment even without cytological or histological proof is therefor
e stressed.
