Management of recurrent post-partum pregnancy tumor with localized chronic periodontitis

Pregnancy tumor is a benign,hyperplastic lesion of the gingiva,considered to be reactive or traumatic rather than neoplastic in nature. the term pyogenic granuloma is a misnomer as it is not filled with pus or granulomatous tissue histologically. it is multi factorial in nature,which shows an exaggerated response to stimuli such as low grade or chronic irritation,trauma or hormonal variations. higher levels of sex hormones during pregnancy produce effects on sub gingival microflora,the immune system,the vasculature and specific cells of periodontium which in turn in the presence of local irritants exaggerate the lesion. since the lesion is clinically indistinguishable from other type of hyperplastic conditions,histological findings are required for proper diagnosis. we present a case report of recurrent pyogenic tumor which showed the evidence of pre-existing localized periodontitis with extensive horizontal bone destruction. the lesion was excised by electrocautery combined with conventional flap procedure after parturition period. during 3 and 6 months follow-up period post-operative healing showed satisfactory results without recurrence.
