Extramedullary plasmacytoma of the adenoids.

Extramedullary plasmacytomas are extremely rarely diagnosed in children. We report two cases of extramedullary plasmacytoma detected coincidentally in the adenoidectomy specimens of children younger than 4 years. We show that these children are disease-free after local excision as the only treatment. Surgical treatment without anti-neoplastic therapy in pediatric plasma cell dyscrasias of the pharyngeal lymphoid tissue may be a sufficient curative therapy.
