Hemangiopericytoma/solitary fibrous tumor of the buccal mucosa: A case report
We report a case of HPC/SFT located in the buccal mucosa. A 50-year-old woman presented with a 5-year history of a painless mass in the left buccal mucosa. Clinical findings showed the lesion was a well-defined tumor between the cheek skin and buccal mucosa with two feeding arteries, indicating hemangioma. The tumor was completely resected under general anesthesia. Histopathologically, immunostaining for STAT6 revealed results consistent with HPC/SFT, and no findings suggestive of malignancy, such as tumor size greater than 5 cm and high proliferative activity as shown by mitotic index and Ki-67 index. No other distinct ...

Intramuscular lipoma involving the masticator space: A case report
We present a rare case of intramuscular lipoma arising from left masseter muscle adjacent to the superficial lobe of the parotid gland and involving the masticator space, spreading to the upper compartment of temporo-mandibular joint (TMJ). Wide excision of the entire lesion was performed under general anesthesia. The postoperative course was uneventful and there was no evidence of recurrence 1 year post-operatively.

Intractable emphysema around the mandibular condyle: A case report
This report describes a rare case of emphysema around the mandibular condyle, which did not recover naturally for more than 3 months. A 54-year-old man was referred for swelling of the left side of the face. While undergoing manual therapy at an osteopathic clinic, he heard an unusual noise and experienced severe pain in his left temporomandibular joint. Computed tomography of his head revealed massive air around the left condyle and fractures of the left condyle and glenoid fossa. These injuries were thought to have occurred during manual therapy at the osteopathic clinic. He was diagnosed with emphysema around the left s...
