We report a case of a 34-year-old male presenting with papules on the right inguinal region for 30 years, along with darkly pigmented lesions for over 10 years. Dermoscopic evaluation of the papules revealed large brown circles adjacent to one another, while dermoscopy of the pigmental lesions showed fissures, milialike cysts and comedolike openings. Histopathology presented epidermal hyperplasia, hyperkeratosis, horn cysts, acanthosis in forms of the accumulation of basaloid keratinocytes, lymphocytes and histioeytes infiltrated in the dermis. The diagnosis is verrucous nevus complicated with seborrheic keratosis.
