PERIPHERAL ODONTOGENIC MYXOMA BACKGROUND – Odontogenic myxoma and peripheral odontogenic myxoma are rare benign odontogenic tumours occurring only in the tooth-bearing areas of the jaws. Odontogenic myxoma is an intraosseous tumour most frequently located in the mandible and occurs predominantly in young adults. Peripheral odontogenic myxoma is located in soft tissue.
CASE STUDY – A 28-year-old female was referred to the Department of Oral and Maxillofacial Surgery, University Hospital of Southern Denmark, Esbjerg, for removal of a mucosal lesion on gingiva. An incision biopsy was made, and histological examination revealed oral focal mucinosis. Excision of the lesion was performed, together with reconstruction with a free palatal mucosal graft. Histological examination revealed peripheral odontogenic myxoma. 3-years follow-up showed no sign of recurrence.
CONCLUSION – The diagnosis peripheral odontogenic myxoma is confirmed by histological examination. Peripheral odontogenic myxoma is treated by surgical removal and curettage. The recurrence rate is low.
