Borrelial lymphocytoma--a case report of a pregnant woman.

Borrelial lymphocytoma (BL) is a rare cutaneous manifestation of Lyme borreliosis. Epidemiological data show that BL is more common in children than in adults. It presents as a single bluish-red swelling located on the earlobe in children, near the nipple in adults. In our paper, we present a case of a pregnant woman with BL, which appeared after tick bite and disappeared completely after antibiotic therapy. The aim of the paper was to emphasize that in tick-borne disease endemic areas BL should be taken into consideration in cases of skin lesions.
