Borrelia-associated lymphocytoma cutis

Excerpt:

We describe a 6-year-old boy who developed Borrelia
burgdorferi-associated lymphocytoma cutis on the ear.
Lymphocytoma is a benign polyclonal B-cell lymphoproliferative
process; it is defined as a subacute manifestation of early
disseminated borrelial infection. Clinical history, physical
examination, and serodiagnosis tests are often sufficient to
establish diagnosis, but sometimes, histopathologic analysis is
needed to exclude malignant cutaneous lymphomas. The outcome is
always favorable but after antibiotic therapy, the lesion
disappears promptly. Copyright (c) 2010. Published by Elsevier
