چکیده
Extramedullary plasmactyoma is the solitary, soft tissue form of plasma cell neoplasm but lack the defining features of medullary or multiple myeloma. The diagnosis is difficult to make in routine practice setting due to the morphological and immunohistochemical overlap with plasmablastic lymphoma. We report a case of plasmablastic extramedullary plasmacytoma in a 52-year-old in the mandibular lingual gingiva and discuss its differential from plasmablastic lymphoma. The gingival mass regressed with primary radiotherapy.

متن کاملExtranodal lymphomas of the head and neck.
Malignant lymphomas represent approximately 5% of all malignant neoplasms of the head and neck and may involve nodal or extranodal sites. Nodal head and neck lymphomas are similar to other nodal sites and are not further reviewed here. The head and neck region is the second most frequent anatomical site of extranodal lymphomas (after the gastrointestinal tract). Most are non-Hodgkin's lymphomas...
