Nodular fasciitis, erythema migrans, and oligoarthritis: manifestations of Lyme borreliosis caused by Borrelia afzelii.


We describe a 35-year old patient with nodular fasciitis, erythema migrans, and gonarthritis four months after a bite of a Borrelia afzelii infected tick. The Borrelia afzelii infection was identified by a polymerase chain reaction and direct sequencing of the amplification product. Borrelia-specific DNA was also detectable in nodular fasciitis tissue. We therefore conclude that Borrelia afzelii can be a causative agent of nodular fasciitis and
Lyme arthritis in a highly endemic region of Northern Germany.
