“…Pemphigus vulgaris (PV) is a rare, chronic, intraepithelial bullous disease with a potentially fatal outcome. Lesions are located mainly in the oral and pharyngeal mucosa, although conjunctiva, larynx, nasal mucosa, vulva, vagina, cervix, glans, anorectal and oesophagus mucosa may also be involved (Ahmed et al, 1980;Hale and Bystryn, 2001;Markopoulos et al, 2006). Although several immunological abnormalities have been demonstrated in patients with PV, the exact mechanism behind the inflammatory changes remains to be elucidated.…”
