Papulosquamous lesions of glans penis.

The presentation of a scaly papule or plaque on the glans penis should suggest more wide-spread papulosquamous disease. Careful examination of the remaining body surface, including the oral mucosa and nails, in almost all cases will yield clues to the correct diagnosis. Papulosquamous disease which may present as a penile lesion include psoriasis, Reiter syndrome, lichen planus, lichen nitidus, seborrheic dermatitis, secondary syphilis, fixed drug eruption, erythroplasia of Queyrat, plasma cell balanitis of Zoon, bowenoid papulosis, and discoid and lichenoid chronic dermatosis of Sulzberger and Garbe.
