Although diffuse thymic hyperplasia after therapy has been reported in lymphomas, no report is found in the medical literature about hyperplasia of other lymphoid tissues following chemotherapy in malignancies as far as we could reach. So, we planned to investigate the nasopharyngeal region of the lymphoma cases during their follow-up while at remission. Children who were in follow-up after cessation of oncological therapy with the diagnosis of lymphoma were evaluated for their nasopharyngeal lymphoid tissues by means of computed tomography. When a mass lesion was diagnosed, biopsies were taken. Among 23 lymphoma cases in follow-up, at a median of eight months (range 1-13 months), eight patients (six Hodgkin's and two Non-Hodgkin's malignant lymphoma) developed nasopharyngeal lymphoid hyperplasia (34.78%) that were proven to be benign by means of biopsies. Two of the patients also developed thymic hyperplasia. Nasopharyngeal hyperplasia regressed in four patients at a median of four months. Nasopharyngeal lymphoid hyperplasia may be diagnosed after the cessation of therapy in lymphomas and whatever the cause, it seems to be a benign process. © 2006 Taylor & Francis.
