title: Generalized cutaneous B-cell pseudolymphoma. Report of a case studied by immunohistochemistry.
abstract: A 77-year-old woman presenting with multiple reddish infiltrated papulonodular lesions on her back is reported. Histologic studies revealed nodular aggregates of lymphoid cells in a B-cell pattern. Immunohistochemical studies of several lesions showed the immunoarchitecture of germinal centers. Generalized lesions of cutaneous B-cell pseudolymphomas are uncommon. Our case is one of the few reported, and the first studied by immunohistochemistry.
