Inoculation (tattoo) leprosy: a report of 31 cases

Abstract

Thirty-one female patients with leprosy lesions starting over tattoo marks observed over a period of 16 years are reported. All the patients belonged to the Chhattisgarh State, which is highly endemic for leprosy. Most of the patients were in the third decade of life. All of them had ornamental tattooing done by roadside tattoo artists, who used unsterile needles for tattooing a large gathering one after another with the same needles. In all of them, the first lesion of leprosy started over a tattoo mark. Twenty-five cases had only single lesion of leprosy exclusively confined to tattoo marks. The duration between tattooing and appearance of first lesion in most of the cases varied from 10 to 20 years. Paucibacillary leprosy was the commonest type observed in 29 cases, while two had multibacillary leprosy. The diagnosis was confirmed by histopathology in all cases. The present report supports the hypothesis of transmission of leprosy in these cases through tattooing. To the best of our knowledge, such a large collection of leprosy cases subsequent to tattooing has not been reported so far.
