Two pediatric cases of primary cutaneous B-cell lymphoma and review of the literature.

Primary cutaneous lymphomas are rare in the pediatric population and most often represent mycosis fungoides or CD30+ lymphoproliferative disorders. Primary cutaneous B-cell lymphoma has rarely been reported in children, and in the past may have been mistaken for disseminated nodal disease or benign cutaneous lymphoid hyperplasias. We describe two cases of marginal zone primary cutaneous B-cell lymphoma in young males. Thus far both have been managed with local therapy. We review the literature of this rare malignancy.
