A case of cutaneous pseudolymphoma with a distinctive appearance treated successfully by intralesional interferon alpha-1b and corticosteroids.

Cutaneous pseudolymphoma (CPL) encompasses various forms of benign lymphocytic proliferative dermatoses that mimic the clinical and/or pathological changes of lymphoma. The clinical manifestations of CPL vary due to differences in the pathogenesis, and accordingly, no specific treatment has been identified. Here, we report a case of CPL on the nose, which had a distinctive appearance and was treated successfully using a combination of intralesional interferon alpha-1b and compound betamethasone (betamethasone sodium phosphate and betamethasone dipropionate).
