Regression of a lesion resembling pyogenic granuloma after endodontic treatment

A rare case of regression of a lesion resembling pyogenic granuloma after endodontic treatment of a maxillary lateral incisor in a 16-year-old female patient is reported. After clinical and radiographic examination, the maxillary right lateral incisor was endodontically treated in two visits. At the second visit, clinical regression of the exophytic lesion was evident and the size of this lesion had been greatly decreased, so was not biopsied. After 3 weeks, the exophytic lesion had totally disappeared. This case report indicates that surgical excision of exophytic lesions resembling pyogenic granuloma is not necessary in all situations.
