Gingival swelling as a manifestation of non-Hodgkin's lymphoma.

A case is reported in which a 52-year-old male patient presented to his dental practitioner with several unusual, purple coloured gingival swellings, the largest of which was about 1 cm in diameter. A careful medical history revealed that the patient had 2 years previously been diagnosed as having low-grade non-Hodgkin's lymphoma (NHL). Prompt referral led to confirmation of the provisional diagnosis of gingival manifestation of NHL and early institution of appropriate treatment.
