[Pemphigoid nodularis--diagnostic and therapeutic difficulties. A case report].

The case of a 62-year-old female patient diagnosed with an extremely rare clinical variant of pemphigoid--nodular pemphigoid, imitating prurigo nodularis, is presented in the paper. In connection with the existence of the typical prurigo nodularis-like appearance in the patient, the diagnosis was maintained for several months. However, because of no response to the treatment and the remarkably chronic course of the disease, the patient was admitted to the Department in order to extend the diagnostics and verify the previous diagnosis. The direct and indirect immunofluorescence examinations performed on the patient enabled the final diagnosis of a rare variant of pemphigoid without typical blisters, and effective treatment was carried out.
