Learning Objectives:
Following this course, the attendee should be able to:

  • Prepare Tzanck smears for diagnosis of certain skin diseases.
  • Identify the characteristic cytologic features of certain skin diseases.
  • Choose the Tzanck smear test instead of unnecessary, harmful, invasive or costly diagnostic procedures.

Cytology is a simple, rapid, and inexpensive diagnostic method which investigates the characteristics of individual cells. Tzanck smears can aid in the diagnosis of various skin diseases, including bacterial, viral and fungal infections, leishmaniasis, pemphigus, spongiotic dermatitis, Darier's disease, Hailey-Hailey disease, granulomatous disorders, and tumoral lesions. This session will teach the preparation of a Tzanck smear and help the attendees to interpret the characteristic cytologic findings of certain skin diseases in daily practice. An algorithmic approach will be given and participants will be encouraged to discuss various case examples that could be diagnosed by a Tzanck smear.
