Pemphigus vulgaris of the uterine cervix revisited: case report and review of the literature.

Pemphigus vulgaris is an autoimmune disease characterized by acantholytic blisters and erosions involving the oral mucosa, skin, and less frequently other mucosal surfaces. Although the cytology of scrapings from the cutaneous and oral lesions has been well-documented, there are relatively few reports in the literature of the cytologic appearance of pemphigus on cervicovaginal smears. This report documents a case of pemphigus involving the cervix, in which the diagnosis was not known at the time of the cervical smear and biopsy. The cytologic features of this case and those in the literature are described in detail, highlighting the necessity of awareness of the disease and its presentation on cervicovaginal smears, in preventing an overdiagnosis of neoplasia.
