Leptospirosis diagnosed by molecular DNA detection on skin biopsy.

Leptospirosis is one of the most common anthropozoonoses in the world. Humans are accidental hosts who get infected through damaged skin or conjunctiva from environmental sources such as soil and water contaminated by urine or tissues from infected animals. We report the case of a young man for whom the diagnosis was obtained by polymerase chain reaction (PCR) detection from a skin biopsy.
