Human Papillomavirus in a Patient With Severe Gingival Overgrowth Associated With Cyclosporine Therapy.

Cyclosporin a is an endecapeptide that has been used clinically since 1978 as an immunosuppressant agent. Although cyclosporine appears to be uniformly beneficial in the treatment of a wide variety of disorders, its use may result in a number of side effects. One of the most important adverse effects is gingival overgrowth. This report relates a case of severe gingival overgrowth in a 31-year-old female who had received cyclosporine therapy in conjunction with a kidney transplant. Because of the severe gingival overgrowth, we analyzed a biopsy, which was positive for human papillomavirus. The case was treated and followed for 18 months.
