A case of flutamide photosensitivity is reported in a patient receivin
g treatment for prostate cancer. Photopatch testing with flutamide at
10 and 20% in acetone was positive and controls negative. Other report
s in the literature indicate that flutamide photosensitivity can be pr
oduced either by UV-A or UV-B, but the small number of reports and the
differences in the rests performed do not allow the specific characte
ristics of flutamide photosensitivity to be established. Presently it
would be advisable, due to the frequent use of this drug, to include f
lutamide in the investigation of photosensitive patients.
