A study of other oral prodrugs of 5-FU such as Tegafur have
suggested Anti-SSA/Ro antibody to be a risk factor for drug
eruptions.7 The authors speculate that 5-FU may translocate
SSA/Ro antigens to the surface of keratinocytes, leading to a
lupus-like eruption.7 While the mechanism remains unclear, it
is evident that capecitabine is responsible for a number of dermatologic
side effects.
As use of this drug continues to grow in the fight against
metastatic breast, colorectal, and genitourinary cancers, it is
important to recognize the breadth of cutaneous clinical presentations
of capecitabine side effects. In conclusion, we present a
unique case of capecitabine-induced SLE concurrent with PPE
successfully treated with cessation of the offending agent and
topical triamcinolone applied to affected areas.
