Oral self-injury associated with septicaemia in a case of Cornelia de Lange syndrome
This report describes a case of septicaemia triggered by SI. The patient was a 40 year-old woman, who was diagnosed with Cornelia de Lange syndrome (CdLS). She was hospitalized in a medical long-term care sanatorium and was recently transferred from a familiar sanatorium. She started to bite herself on the mandibular labial alveolar mucosa; this had never been observed. As the self-biting wound gradually increased and the resultant inflammation spread to surrounding tissues, she was referred to our hospital. During the course of treatment, she suffered from septicaemia secondary to aspiration pneumonia. When a case of SI...

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 dist...

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...

Stromal cell-derived factor-1 accelerates bone regeneration through multiple regenerative mechanisms
ConclusionsOur findings suggest that the local administration of SDF-1 enhances bone regeneration by inducing multiple endogenous tissue-regenerating activities. (Source: Journal of Oral and Maxillofacial Surgery, Medicine, and Pathology)

Venous malformation at the upper lip treated with sclerotherapy – A case report
Publication date: Available online 8 March 2019Source: Journal of Oral and Maxillofacial Surgery, Medicine, and PathologyAuthor(s): Shirou Tabe, Manabu Habu, Michinao Kawano, Osamu Sakaguchi, Izumi Yoshioka, Kazuhiro TominagaAbstractAlthough vascular malformations of the head and neck present several challenges, sclerotherapy with ethanolamine oleate (EO) is effective. A 23-year-old woman presented to our institution with a mass under the mucosa and skin of the upper lip. A low-flow-type venous malformation was diagnosed based on findings from magnetic resonance imaging (MRI) and angiography. We injected 5% EO as the scler...
