Cutaneous lymphomas are the most frequent extranodal lymphomas after digestive lymphomas. A quarter are B-cell lymphomas. 80% of cutaneous B cell lymphomas are indolent cutaneous B cell lymphomas. These indolent cutaneous B cell lymphomas are characterized by good prognosis (survival rate at 5 years: 90%), but also by the frequency of cutaneous recurrences. The radiotherapy is currently the most widely used treatment, with complete response rate close to 100% for a lesion treated. However, it has limits when there are outset multiple lesions inaccessible to a single radiotherapy field (concerning one case in three), or during recurrences. In these situations, conventional chemotherapy is not recommended and multi-field radiotherapy is often used empirically, but its effectiveness has never been studied prospectively.
Recently, retrospective studies with small numbers patients (totaling sixty patients) reported complete response rates of 80 to 100% with rituximab (anti-cluster of differentiation antigen 20 (CD20) antibodies) used as monotherapy in non-standardized treatment by intravenous with a recurrence rate of less than one case in three. These data suggest that rituximab by intravenous with a standardized initial cycle followed by a maintenance therapy could improve the prognosis of indolent cutaneous B cell lymphomas with multiple lesions or of recurrent lesions.
