Odontogenic myxoma in an 8-year-old girl: A case report with review of literature

Soft Tissue Fibromyxoma of Non-odontogenic Origin and Its Management With Dental Lasers: A Case Report

Myxomas are a group of benign tumors that have a common histologic appearance of fibrous and myxoid ground substance. According to literature, myxomas often occur between the ages of 30 and 50 years. Very often, intraoral soft tissue myxoma can be misinterpreted as malignant and is difficult to differentiate from other tumors with myxoid stroma. Of the different variants of soft tissue myxoma, intraoral is an extremely rare, slow-growing, benign ectomesenchymal tumor. We report a case of a 75-year-old female who presented with soft tissue swelling in the upper front tooth region. No history of pain over the lesion or bleeding was seen during brushing. On intraoral examination, a lesion measuring 2 x 3 cm was seen in the interdental papilla involving the attached gingiva of 22 and 23. An excisional biopsy of the lesion using a diode laser followed by low-level laser therapy revealed oral soft tissue fibromyxoma without odontogenic origin. A case of oral soft tissue myxoma is presented for its rarity and differential diagnosis of localized oral cavity lesions.

Conservative Management of Odontogenic Myxoma - A Case Report

Rationale

This is a 14-year-old girl with odontogenic myxoma of the right posterior mandibular region, which was managed conservatively by intraoral marginal mandibulectomy rather than segmental mandibulectomy.

Patient Concerns

The patient and her parents were concerned about her aesthetics.

Diagnosis

The patient came with the complaint of swelling on the right lower back tooth region of the jaw, which was not associated with pain. On palpation, the swelling was bony hard and there was buccolingual expansion. On radiographic examination, there was a sunray appearance. Histopathological examination confirmed it to be an odontogenic myxoma.

Treatment

Marginal mandibulectomy was done for the patient. The whole procedure was done intraorally and closed using primary closure.

Outcomes

Postoperatively, the patient was asymptomatic and is on follow-up.

Take-away Lessons

We can say that odontogenic myxoma can be managed conservatively.

Diode laser on excision of giant peripheral odontogenic myxoma: a rare case report and literature review

It was to report a rare case of peripheral odontogenic myxoma removed with high-power diode laser and to do an extensive review of studies of odontogenic cysts and tumors treated with high-power laser (HPL). This is a rare case of a 63-year-old male patient with a peripheral odontogenic myxoma measuring approximately 10 cm in the attached gingiva region of tooth 16 removed with a high-power diode laser (808 nm, 3 W, in continuous mode, under constant suction, with 400-µm optical fiber). A literature review was also carried out looking for articles that involved the use of HPL in the treatment of odontogenic cysts and tumors, without restriction of year or language. In the present case, there was no need for suturing, no postoperative discomfort, and minimal bleeding during the procedure. In a 12-month follow-up period, there were no signs of recurrence. Only two cases of intra-osseous odontogenic myxomas treated with HPL and 10 cases involving other odontogenic cysts and tumors were found. All studies showing HPL to be effective in treating these lesions. Despite the different types of lasers used and different parameters, it is observed that lasers are effective in the treatment of odontogenic lesions.
