Bowenoid Papulosis
Grossly, bowenoid papulosis presents as a multiple, pigmented (violet) papules in the penile shaft. It may mimic condyloma acuminatum grossly. Patients are generally two decades younger than those with Bowen's disease.
Bowenoid papulosis is histologically indistinguishable from Bowen's disease, but, in contrast to Bowen's disease, evolution into invasive carcinoma is rare.
