Disseminated superficial porokeratosis involving the groin and genitalia in a 72-year-old immunocompetent man
The porokeratoses are a group of disorders of
abnormal epidermal keratinization resulting in the
characteristic histologic feature of the cornoid
lamella. Several clinical variants of porokeratosis
exist, which are unified by this common histologic
feature but differ in morphology, distribution, and
clinical course. The typical lesions of porokeratosis
are characterized by an atrophic center surrounded
by an elevated keratotic rim formed by the cornoid
lamella. The lesions can be found almost anywhere
on the body; however, the groin and genitalia are
rarely involved. We report an unusual presentation
of a rare clinical variant
