Case 2. A 10-year-old girl developed swelling of the left zygomatic region but had no symptom on the nasal region. Partial resection and curettage of tumor was made under exploratory maxillary srugery, with recovery of the figure of the face.
Case 3. A 10-year-old girl sufferd from swelling of the right zygomatic region and nasal obstruction. Under roentgenological examination, no infiltration of the tumor was seen to the lateral and frontal wall of the maxi llary cavity.
