Contact dermatitis from natural latex of condom has been reported and is attributed to latex sensitivity. Chemical leukoderma from rubber condom is probably not reported. Here we present a case of chemical leukoderma in a 32-year-old male who developed depigmentation around the shaft of the penis in a circumferential pattern. Since the lesion was solitary and the site corresponded to the point of maximum contact of the condom, a diagnosis of contact leukoderma due to latex condom was thought of. Patch testing was done with mercaptobenzothiazole (MBT), dusting powder present in the condom and condom latex as such. The patient tested positive (3+) with mercaptobenzothiazole and the condom latex. On discontinuation of condom use and with UVB phototherapy, lesions repigmented in eight weeks.
