A 62-year-old Black man with a history of atopic dermatitis presents to the clinic with persistent itchy bumps on his arms, legs, and back. The patient reports that the bumps have been present for several years. The bumps are firm and he reports scratching them often. The patient has tried treating the itching with topical corticosteroids with minimal benefit. On physical examination, hyperpigmented hyperkeratotic papules and nodules are found on bilateral extensor forearms, shins, and upper back. Other than the skin condition, the patient is healthy, has no other chronic medical conditions, and takes no medication. No further testing, including biopsy, is performed.
