Primary small B-cell lymphoma (MALT lymphoma) at lingual tonsil: a case report.

Aims: Primary non-Hodgkins lymphomas of the oropharyngeal region are rare. We report a case of a small B -cell lymphoma (MALT lymphoma) involving base of tongue. The patient was successfully treated with wide excision of the lesion followed by radiotherapy. Presentation of Case:A 75-year-old female Caucasian patient was referred to our clinic with complaints of foreign body sensation in the throat and progressively worsening snoring over 4 months. Oropharyngeal examination revealed a 3x3 -cm smooth mass originating from the left side of the base of tongue and moving with protrusion of the tongue. Excisional biopsy revealed a low -grade small B-cell lymphoma with lambda monoclonal plasmacytic differentiation (extranodal marginal zone lymphoma of mucosa-
