Answer

Drug eruptions can mimic a wide range of dermatoses. The morphologies are myriad and include morbilliform (see the image below), urticarial, papulosquamous, pustular, and bullous. Medications can also cause pruritus and dysesthesia without an obvious eruption. A drug-induced reaction should be considered in any patient who is taking medications and who suddenly develops a symmetric cutaneous eruption. Morbilliform eruption localized to striae has been described with clindamycin. [1]
