Lymphocytoma - like erythema migrans - belongs to the first stage of a borrelia infection and manifests itself as intensive reddening which appears particularly in places where expansion is no longer possible such as ear lobe, nose, navel, nipple, scrotum.
Facial paralysis, especially peripheral facial paralysis, is not that rare. Formerly the appearance of facial paralysis was regarded as 'ideopathic', i.e. arising without a tangible cause. Since then it has become apparent that facial paralysis in children is a possible consequence of a borrelia infection. Facial paralysis belongs to stage 3 (neuroborreliosis). All stages of a borrelia infection need consistent treatment with antibiotics.
