Abstract

Ameloblastoma is characteristically considered to be a benign but locally aggressive and infiltrative odontogenic tumor with a high recurrence rate. Because of its locally invasive nature, the recurrence rates for the ameloblastoma post treatment remains high. Recurrence also seems to depend on the histological type of the tumor and the treatment modalities used. Curettage alone is reported to have led to a 90% recurrence rate for mandibular tumors and a 100% recurrence rate for maxillary tumors in literature. In a sample of 327 cases in a large study, a 17.7% recurrence rate was noted after radical treatment and a rate of 22.6% was noted after conservative treatment; granular and follicular variants of ameloblastomas were seen to recur more frequently than the plexiform type. Most recurrences occur at the site of the primary tumor. However, lesions are also known to recur in bone grafts, and rarely, recurrence involves adjacent soft tissues. In this study, we present an unusual case of a plexiform ameloblastoma that recurred in the left mandibular residual soft tissue 8 years after the first surgery i.e. disarticulating hemimandibulectomy. The patient is on regular follow up post second surgery for 23 months and she has been symptom free till now.
