Tzanck smears can be used for the diagnosis of cutaneous infections, autoimmune disorders and cutaneous tumors. To exemplify its use, we report a case of a female patient with pemphigus vulgaris whose diagnosis was confirmed by positive direct immunofluorescence and conventional cytology using smears obtained by scraping the cheek mucosa.
