Complete examination of the skin focusing on the sites commonly affected by psoriasis including the elbows, knees, scalp, lower back, gluteal cleft, and nails may reveal other areas of involvement to aid in diagnosing psoriasis. If no other psoriatic plaques are noted, differentiation from hand and foot dermatitis can be difficult. A biopsy may be helpful in this instance. A KOH examination should be performed to rule out a dermatophyte infection. Bacterial and viral cultures should be obtained when disease is localized to one area.
