Abstract

Background  In the present study, Borrelia spirochetes were found in four (26,6%) out of 15 patients with Atrophoderma of Pasini and Pierini (IAPP) and lichen sclerosis et atrophicans (LSA) from the Brazilian Amazon Region.

Material and methods  Borreliosis was investigated by immunohistochemistry and focus floating microscopy for Borrelia burgdorferi in skin biopsy samples from 15 patients with both clinical and histopathology evidences compatible with Morphea, LSA, and IAPP.

Results  Spirochetes were detected by specific immunohistochemistry and focus floating microscopy for B. burgdorferi in samples from three patients. A limitation of our study was the fact that we were not able to isolate and culture these organisms.

Conclusion  Our data confirm the presence of borreliosis cases in the Amazon.
