Pseudolymphoma or benign lymphoid hyperplasia is an uncommon benign lymphoproliferative lesion that occurs very ralely in the oral mucosa, most commonly in the hard palate. It is important to differentiate between malignant lymphoma and pseudolymphoma with similar clinical and morphological symptoms. Clinically, pseudolymphoma is a firm, painless, nonulcerated, nonfluctuant, slowly growing mass or swelling on the one side of the palate. However, lymphoma at hard palate is unilateral, and some are hard, painful, or show evidence of bone destruction. The treatment of pseudolymphoma is local excision.
