We describe two patients with unusual asymptomatic, papular lesions on the
vulva, clinically resembling lichen planus, the histology of which revealed
unexpected findings of suprabasilar clefting, acantholysis and dyskeratoti
c cells giving rise to corps ronds and grains together with hyperkeratosis
and parakeratosis. features originally associated with a diagnosis of Darie
r's disease. Focal acantholytic dyskeratosis has been described in a wide v
ariety of inflammatory and neoplastic processes including those involving m
ucous membranes and has been attributed various diagnostic labels. We feel
that the findings in our patients are consistent with a diagnosis of papula
r acantholytic dyskeratosis of the vulva, a rare condition, which was first
described in 1984.
