Severe gingival overgrowth associated with cyclosporine therapy

A case of severe gingival overgrowth secondary to cyclosporine therapy in a 19-year-old black male who received a liver allograft transplant is reported. Clinical examination revealed a severely overgrown and inflamed gingiva. Surgical excision of the excess tissue was accomplished under general anesthesia. Healing occurred uneventfully, with acceptable contours; however, some regrowth was evident as early as 2 months. Spontaneous repositioning of the teeth was also seen postoperatively. Examination of the excised tissues revealed alternating areas of dense collagen and myxomatous change. An inflammatory infiltrate primarily of plasma cells was present. There was no evidence of an increased number of fibroblasts in the specimens examined.
