Abstract
|
|
|
|
Myofibroblastic sarcoma (MS) is an extremely rare form of head and neck tumor that originatesfrom mesenchymal cells. Myofibroblasts are mesenchymal spindle cells that share the featuresof fibroblasts and smooth muscle cells. Radiologic examinations such as CT and MRI are usefulfirst-line diagnostic tools for differential diagnosis. Complete surgical excision is recommendedfor successful treatment. MS can be classified as low, intermediate or high grade consideringits histological differentiation and time course. Intermediate and high grade MS are known to be relatedto local recurrence or distant metastasis. With a review of literature, we report a case of MS arisingfrom the left buccal mucosa in a 56-year-old male who complained of a painless left buccalmass. The patient was successfully treated by margin-free excision and the pathologic findingsconcluded as intermediate grade without any complication. There was no recurrence observed fortwo years since the surgery.
