Successful treatment of primary non-Hodgkin's lymphoma of the vulva with radiation therapy.

Vulva, as a primary site of malignant lymphoma in women, is extremely rare. We report herein an 83-year-old patient with a primary, stage IIE vulvar, follicular center cell, B-cell lineage non-Hodgkin's lymphoma (NHL), with an excellent response to radiation therapy and event-free survival of 18 months. Early-stage primary vulvar NHL can be successfully treated only by limited field irradiation.
