Summary

Aim: Pemphigus vulgaris (PV) is a rare, life-threatening autoimmune bullous disease that can involve the skin and mucous membranes, characterized by intraepidermal bullae and eroded lesions caused by rupture of the bullae. The aim of this study is to research the relationship of the findings obtained with Tzanck smear, which is an inexpensive and easy method, with disease activity and its prognostic importance in the clinical course in PV patients. Material and Methods: Pemphigus patients who visited to Goztepe Prof. Dr. Suleyman Yalcın City Hospital, Dermatology Clinic will be included in our study. Pemphigus disease area index (PDAI), Tzanck smear findings from the lesions and desmoglein levels during routine follow-up of patients with pemphigus vesicle/bulla/erosion will be evaluated. In the evaluation of Tzanck smear preparations, the entire slide will be scanned, acantholytic cell count performed and scored 1 to 4 accordingly (1 point: 1-3 cells, 2 points: 4-10 cells, 3 points:11-20, 4 points: \>21 cells or cell clusters). Anti-desmoglein antibody levels will be analyzed by using enzyme-linked immunosorbent assay (ELISA) method.
