We describe seven patients who developed malignancy before, after or a
t the onset of systemic lupus erythematosus (SLE). They comprise three
cases of breast adenocarcinoma, two cases of Hodgkin's lymphoma, and
one each of cholangiocarcinoma and thymoma. Only one of this group had
been treated with cytotoxic agents, and five have subsequently died.
They belonged to a group of 150 SLE patients, many of whom had been tr
eated with steroids and cytotoxic agents, under long-term follow-up at
a specialized lupus clinic. We discuss the reported association of ma
lignancy in patients with SLE.
