Osteo-cutaneous acanthamoebiasis in a non-immunocompromised patient with a favorable outcome.

Osteo-cutaneous form is a rare presentation of acanthamoebiasis. We present the first such case from India in an apparently healthy male who developed cutaneous lesion with bone involvement after traumatic inoculation of Acanthamoeba cysts. The diagnosis was established by routine microbiological techniques and confirmed by 18SrRNA gene sequencing. Aggressive therapy with terbinafine, chlorhexidine, rifampicin and co-trimoxazole was successful in clearing the lesion and preventing encephalitis.
