Although most hyperpigmented lesions are benign and the diagnosis is straightforward, it is important to exclude melanoma and its precursors and to identify skin manifestations of systemic disease. Treatment options for postinflammatory hyperpigmentation, melasma, solar lentigines, and ephelides include the use of topical agents, chemical peels, cryotherapy, or laser therapy. Read More

Atopic dermatitis is an inflammatory, chronically relapsing, highly pruritic skin disorder that has considerable impact on the quality of life. As corticosteroids are not ideal for long-term control of the disease because of their potential side effects, steroid-free topical immunomodulators have recently been developed for the treatment of atopic dermatitis. Although clinical trials do not indicate an increased risk of cutaneous infection, the clinician must be careful about viral infections such as eczema herpeticum or molluscum eczema that can be observed during treatment with pimecrolimus and tacrolimus.
