Gingival hyperplasia by nifedipine. Report of a case.

We describe a case of gingival hyperplasia in a 36-year-old renal transplantation recipient treated with nifedipine for severe arterial hypertension. The appearance of the gingival disorder was probably related to nifedipine intake. Histologically, in addition to the findings of acanthosis, papillomatosis and connective tissue hyperplasia, there was also an important plasma cell inflammatory infiltrate.
