Bexarotene and Interferon-α Combination Therapy in a Patient Affected by Relapsing Anaplastic Large Cell Lymphoma with Cutaneous Involvement

A 74-year-old man presented with relapsing systemic anaplastic large cell lymphoma (ALCL) with cutaneous involvement who had a third recurrence of cutaneous lesions associated with inguinal lymphonodes enlargement. Due to severe worsening of general conditions, treatment with low dose bexarotene associated with interferon-? was initiated. Four months later, skin nodules disappeared with reduction of lymphonodes size. Two months after stopping therapy, lymphonodal relapse of the lymphoma was seen; however, cutaneous lesions were still in complete remission. Association of low dose bexarotene with interferon-? seems to represent a possible alternative therapy for relapsing systemic ALCL presenting as prevalent cutaneous involvement in patients with severe worsening of general conditions. In our case, this protocol was unable to maintain a longer disease free survival in comparison with the 2 previous polychemotherapy cycles. Further extended studies are required in order to define the possible rule of this combination therapy in relapsing sYstematic ALCL.
