Granular cell tumors are rare soft tissue tumors, derived from Schwann cells. About half of them occur in the head and neck, but a case with tumor arising in the zygomatic region has not been reported to our knowledge. We report a case of granular cell tumor arising in the zygomatic region. A 57-year-old woman was referred to our hospital because of cheek swelling. MRI findings showed a benign tumor, so the patient wished follow-up. However, the tumor gradually grew in size for 11 months, as was confirmed by MRI. Since the patient desired removal of the tumor, the operation was performed by the intraoral and subcilial approach. The histopathological diagnosis was granular cell tumor. Judging from the operative finding, we supposed the origin of the tumor to be the zygomaticofacial nerve which is a branch of the maxillary nerve. Twenty-six months after the operation, there was no sign of recurrence.

Sialoliths commonly occur in the submandibular gland, and parotid gland sialoliths, especially parenchymal sialoliths, are rare. As a minimally invasive surgery, we report here endoscopic removal of a parenchymal sialolith of the parotid gland under local anesthesia.A female in her 40s with swelling and pain in the left buccal region was referred to our department for endoscopic removal to avoid extraoral removal after diagnosis of parotid sialolith in another hospital. Computed tomography showed that the parenchymal sialolith of the left parotid gland was 1.7×1.4×1.0 mm in size. The patient underwent endoscopic removal of the sialolith under local anesthesia as minimally invasive surgery. Complete removal was performed and the postoperative course was uneventful without complications such as swelling of the parotid gland.

A glandular odontogenic cyst (GOC) is a rare odontogenic cyst, classified as a new developmentalodontogenic cyst by the WHO in 1992. It frequently arises in the anterior region of the mandible. Histopathologically, GOC is lined by epithelium of varying thickness, which contains mucous cells and vacuolations. Some casesshow clinically invasive growth, leading to a high rate of recurrence despite surgical excision. Some studies haveestimated that the overall recurrence rate is 27%.We report a case of GOC arising in the right mandibular third molar region. The patient was a 34-year-old man.Surgical excision was performed. One year 4 months after the operation, the prognosis was good, with no signs of recurrence.
