Case 1

A 38-year-old man presents to the clinic complaining of numerous pruritic lesions on his right lower extremity. He claims that all of the lesions appeared within the past 3 months. He denies similar occurrence and reports no history of skin conditions, although he states that his mother often breaks out in a “rash” on her limbs during the summer months. On examination, several scaly, round, erythematous plaques with keratinic centers are noted on his anterior right leg. Biopsy is performed, revealing cornoid lamella and a thin epithelium.
