Secondary malignancies represent an increasing problem for long surviv
ors of primary malignancies treated by chemo- and/or radiotherapy. The
occurrence of secondary myelodysplasia and leukaemias after treatment
for Hodgkin's disease is well established. Secondary solid tumors are
mostly observed following radiation therapy. We report the case of a
patient who presented 3 abdominal solid malignancies within 3 years, 2
9 years after abdominal radiotherapy for a testicular seminoma, namely
2 colon cancers and a peritoneal mesothelioma. Both types of cancer a
re independently reported in the literature to be more frequent in pat
ients with a history of abdominal radiation than in the general popula
tion, To our knowledge there is no other reported case with 3, nearly
simultaneously occurring separate solid tumors, which could all be rel
ated to former abdominal irradiation, Such a radiotherapy-related long
term side effect should be taken into account when considering adjuvan
t radiotherapy in patients with low-risk stage I testicular seminoma.
