MANDIBULAR JUVENILE MONOSTOTIC FIBROUS DYSPLASIA, A COMMON LESION WITH UNUSUAL PRESENTATION; CASE REPORT AND LITERATURE REVIEW.

Abstract

BACKGROUND: A diagnostic dilemma exists between lesions with similar clinical and radiographic features. Aim: We present a case of a dilemma between Garre’s osteomyelitis and juvenile monostotic fibrous dysplasia (FD) in a 13-year-old boy with toothache from a carious tooth.
CASE REPORT: This case study reports a rare instance of mandibular monostotic fibrous dysplasia in a 13-year-old male patient, which
presented alongside a carious tooth (number 37). While fibrous dysplasia commonly affects the maxilla, the aetiology in this case remains unknown. The patient exhibited symptoms of toothache and left-sided mandibular swelling, with more buccal and slight lingual cortical expansion—sparing the lower border—and radiographic features initially suggestive of Garre’s osteomyelitis—treatment involved osseous recontouring of the expanded buccal cortex.
RESULT: The histopathologic report of the shaved bones revealed the lesion to be juvenile monostotic fibrous dysplasia (FD). Over a fiveyear follow-up period, the patient showed no signs of recurrence.
CONCLUSION: To the best of our knowledge, this is the first reported case of a dilemma between Garre’s osteomyelitis and monostotic
fibrous dysplasia in Nigeria
