[Cutaneous pseudolymphoma caused by carbamazepine]

Drug-induced cutaneous pseudolymphomas are poorly reported. They clinically and pathologically mimic malignant lymphomas but their evolution is benign after drug withdrawal.

We herein reported a case of carbamazepine++-induced pseudolymphoma in a 30 year-old woman of particular interest because of the paucity of clinical symptoms (only six papules of less than one centimetre each).

Phenytoins, carbamazepine++, barbiturates and ACE inhibitors are the main drugs inducing cutaneous pseudolymphomas. These usually mimic T-cell lymphomas. The clinical spectrum of cutaneous pseudolymphomas is broad including severe aspects, such as erythroderma or tumoral eruption and benign appearing one as in our case. Drug investigation is mandatory for each patient with lymphoma appearing cutaneous infiltrates because dramatic and definitive healing of the lesion is always expected in case of pseudolymphoma.
