Rare case report of cyclosporine induced gingival hyperplasia

However, in the following years he presented with complaints of swelling of feet and breathlessness of 10 days duration. A thorough general clinical examination was carried out, suggestive of moderate pallor and pitting edema of feet.

Examination of oral cavity revealed significant gingival overgrowth in buccal mucosa of maxilla as well as mandible.

Furthermore, on lab evaluation his Hb was 8.8 g/dl, serum urea was 116 mg/dl and serum creatinine was 5.2 mg/dl. Serum cyclosporine level was 137 nmol/L (within therapeutic range). Renal graft biopsy was then done, suggestive of chronic allograft nephropathy.

Patient was not on medications like phenytoin or CCBs. The authors then made a final diagnosis of post renal transplant chronic allograft nephropathy with cyclosporine induced gingival hyperplasia.

Hence, the authors concluded that "gingival hyperplasia is a known complication of cyclosporine therapy and is more common in children and adolescents as compared to adults."

It can also be caused by drugs like phenytoin and CCBs. The degree of gingival hyperplasia is unrelated to the dose and levels of cyclosporine. Usually, the gingival overgrowth regresses after discontinuing the drug, they further added.
