“…To date, the presence of speckled IgG antibody deposits in the lower third of the epithelium has been described only in CUS and not in any other immunological disease, even though Chorzelski has described positive DIF findings in 4 cases without oral lesions (Chorzelski et al, ; Olszewska, Jarząbek‐Chorzelska, Kołacińska‐Strasz, Blaszczyk, & Jabłońska, ). Only in vulvovaginal‐gingival‐pilar LP (VVG‐LP), an in vivo SES‐ANA deposition was detected, also in the genital mucosa, but the disease presents with several clinical features different from those of CUS; hence, further research is required to clarify the immunological relationship between CUS and VVG‐LP (Olszewska et al, ).…”
