Sir,

A 9 year cerebral palsy girl was on phenytoin since 3 years of age. She is not on regular follow-up. At present follow-up, she was on phenytoin 7 mg/kg/day. On examination coarse facies, gum hypertrophy and hirsutism was present [Figure 1]. She was seizure free and blood counts, liver function tests, kidney function test, blood sugar and serum calcium were normal. When the seizures began, a computed tomography scan of the brain showed dilatation of the ventricles. The prevalence of phenytoin-induced gingival overgrowth is 15-50%. [1],[2],[3] Debate is ongoing regarding whether drug-induced gingival overgrowth is due to hyperplasia of the gingival epithelium or of submucosal connective tissue and/or both. Risk factors known to contribute include the presence of gingival inflammation resulting from poor oral hygiene. Furthermore, the presence of dental plaque may provide a reservoir for the accumulation of phenytoin. [1] In a study by Thomason et al. showed a significant correlation between plaque score and gingival overgrowth in the phenytoin-treated patient; however, there was no correlation between gingival overgrowth and salivary concentration of the drug. [3] Phenytoin has been shown to induce gingival overgrowth by its interaction with a subpopulation of sensitive fibroblasts. Phenytoin also increases the serum concentration of basic fibroblast growth factor, 3 fold and has correlated with gum hyperplasia. [1] Morbidity can be because of gross overgrowth of gingival tissue, which can lead to gingival bleeding, pain, teeth displacement and periodontal disease. Hirsutism occurs in 8-12% of children receiving phenytoin. [4] It occurs on the extensor surfaces of the extremities, on the trunk and face. In children cosmetic effects of gingival hyperplasia and hair aggravates after chronic phenytoin therapy.{Figure 1}
