Borrelial lymphocytoma cutis: a diagnostic dilemma.

Lymphocytoma cutis (LC) is one of the most common types of cutaneous B cell pseudolymphoma. Borrelial LC occurs most commonly in areas endemic for Ixodes ricinus tick in Europe, and it is rare in North America. The disease is rarely seen in India and may cause diagnostic difficulties for dermatologist residing in parts of the world that are not endemic for Lyme disease. The diagnosis is critical as LC may present as the only early manifestation of Lyme disease. Herein, we have presented a case of borrelial LC in an 11-year-old boy of German descent, residing in India.
