Involvement of the female genital tract with PV might not be as infrequent as was previously thought; it is probably the second most common mucosal site of PV after the oral mucosa. Genital lesions may be missed and the need for thorough pelvic examination should not be overlooked.
Regarding the relatively high sensitivity of DIF on plucked hair in PV patients with positive oral mucosal DIF in our study, it seems that hair plucking is a suitable alternative to the more invasive techniques of skin or mucosal biopsy for obtaining specimens for DIF in PV.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
