Psoriasis with extramammary paget disease in a male: a case report.

Psoriasis is a chronic inflammatory skin disease that is characterized by erythematous, sharply demarcated papules and plaques covered by scales. Extramammary Paget disease (EMPD) is a uncommon neoplastic condition of apocrine gland-bearing skin and its occurrence in combination with psoriasis is very rare. We report an interesting case of a 61-year-old male with extensive psoriasis presented with penoscrotal EMPD, which was confirmed by histopathological stain.
