  To the Editor, Top


Contact leucoderma has been reported with bindis and footwear.[1],[2] It is caused mainly by paratertiary butyl phenol used in adhesives of bindi and footwears.[3] We are reporting an unusual case of contact depigmentation due to lemon which was rubbed over the face.

A 20-year-old girl presented with patchy depigmentation which she developed after 5 days of rubbing fresh lemon over the face. After few hours of rubbing, she felt burning over the site. On second day of application she developed redness, itching and scaling. After exfoliation lesions healed within 5 days and left depigmented patches.

Contact depigmentation may be due to direct toxic effect of chemicals on melanocytes[4] or due to development of immunological reaction (contact dermatitis) followed by depigmentation as in bindi dermatitis.[5] In our patient the depigmentation produced by lemon was probably because of direct toxic effect over melanocytes as patch test to lemon juice was negative.
