title: Cutaneous pseudolymphoma due to topical application of 4% hydroquinone cream for melasma.
abstract: Cutaneous pseudolymphoma is an aggregate of mature or abnormal looking lymphocytes in the dermis, which clinically and /or histologically simulates lymphoma but has a benign course and outcome. Systemic drugs, especially anti-epileptics, are an important cause of cutaneous pseudolymphomas. Pseudolymphoma of the skin, secondary to topical drug application, is very rare. We report a case of cutaneous pseudolymphoma induced by local application of 4% hydroquinone cream to melasma over the cheeks.
