The patient was also examined by a rheumatologist (systemic lupus erythematosus was excluded, dynamic observation was shown). He received treatment with hydroxychloroquine, aevit and venarus; externally — Lorinden A ointment, bepanten plus cream, shampoos containing zinc, ultraphonophoresis with hydrocortisone ointment course.
