BACKGROUND: Extra-axial chordomas are exceedingly rare malignant tumours. Herein, we present the first case of an extra-axial chordoma in the gingivae. METHODS AND RESULTS: A 21-year-old man presented with a suspected chordoma in the upper right gingiva. Diagnosis was difficult; however, owing to strong expression of the chordoma marker brachyury, extra-axial chordoma was ultimately diagnosed. The tumour was completely resected without performing a facial incision...

Secondary carcinogenesis within the irradiation range is one of the most severe problems in cancer survivors. A 60-year-old woman developed hypopharyngeal carcinoma, and she received radical surgery and postoperative radiotherapy. Eight years later, brown pigmentation and induration were observed in the left subaural region. Fine-needle aspiration biopsy revealed malignancy and the parotid tumor was diagnosed as recurrence of hypopharyngeal carcinoma. Neoadjuvant chemotherapy followed by radical parotidectomy was performed...

OBJECTIVE: The treatment of all forms of sinonasal inverted papilloma (IP) is a complete, wide, local resection. The main surgical purpose is to remove all diseased mucosa and mucoperiosteum, together with a cuff of normal-looking mucosa at the attachment site, followed by drilling and/or coagulation. Our aim is to present our experiences in endoscopic surgical management of IP by using attachment-oriented excision. METHODS: We present 20 cases of sinonasal IP. The data collected includes the histopathological diagnosis, staging, extension of the tumor, tumor attachment site, approach to surgery, serum squamous cell carcinoma antigen (SCCA) level, and recurrences...

Papillary thyroid carcinoma (PTC) occasionally invades tracheal cartilages. We adapted a reconstructive procedure "modified spiral tracheoplasty" to extensive tracheal defect after resection of locally advanced thyroid cancer. Extensive window resection of tracheal wall was performed in a 72-year-old woman and a 48-year-old man with PTC invading intraluminal trachea. Remaining stumps of trachea were separated from the esophageal wall and were rotated by 90 degrees in opposite directions. Posterior and lateral walls were anastomosed and tracheocutaneous fistula was created to prevent postoperative airway obstruction...

OBJECTIVE: Microglia are highly specialized tissue macrophages in the central nervous system. Their activation in the auditory system has been reported in adult hearing loss models, but their status in the developing auditory system is less understood. Therefore, we investigated microglial status in the cochlear nucleus (CN) during normal developing periods and after exposing rats to amikacin, a potent ototoxin, around the time of hearing onset. METHODS: To develop the deafness model, rats were administered with a daily intraperitoneal injection of amikacin (500 mg/kg) from postnatal day 7 (P7) to P15...

Adenoid cystic carcinoma (AdCC) with high-grade transformation (AdCC-HGT) is rare, and AdCC-HGT with spindle cell component is particularly rare. The patient was a 65-year-old man with a 5 cm sized swelling of the right submandibular gland. Submandibular sialoadenectomy was performed. Histopathological findings mainly showed conventional AdCC, and minorly showed two other components: (1) the pleomorphic component, a proliferation of atypical pleomorphic epithelial cells forming solid or small clusters and accompanied by necrosis; (2) the spindle cell component, containing atypical spindle cells invading the stroma...

OBJECTIVE: The fiber-guided carbon dioxide (CO2 ) laser is a useful device for laryngopharyngeal surgery. The flexible CO2 wave-guide laser has been developed and commercially available for several years. However, the transnasal use of CO2 flexible wave-guided laser surgery through the instrument channel of a flexible endoscope (CO2 TNFLS) is not permitted in Japan. This feasibility study aimed to assess the value and the safety of an in-office CO2 TNFLS procedure. METHODS: Patients with small laryngopharyngeal diseases were enrolled from June 2015...

As has been well recognized, methotrexate (MTX) leads to a state of immunosuppression and can provide a basis for the development of lymphoproliferative disorders (LPDs). MTX-associated LPDs can affect nodal sites as well as extranodal sites, though the manifestation of an LPD in the form of multiple pulmonary nodules is rare. Here, we report two cases of MTX-associated LPD with multiple bilateral pulmonary nodules, which was a finding suggestive of lung cancer, and bilateral cervical lymphadenopathy. After withdrawal of MTX, the multiple bilateral pulmonary nodules and bilateral cervical lymphadenopathy disappeared without chemotherapy in both cases...

Objective The endocytosis of cationized feritin (CF) via a clathrin-mediated pathway is regulated by a signaling network. Marginal cells showed the active endocytosis of CF via a clathrin-mediated pathway. The internalization of receptors through this clathrin-mediated pathway is an important regulatory event in signal transduction. Numerous kinases are involved in endocytosis, and each endocytic route is subjected to high-order regulation by cellular signaling mechanisms. In this study, we investigated whether ROCK and MLCK signaling cascades and G-proteins regulate the endocytosis of CF in marginal cells of the stria vascularis...

REVIEW
Hiroshi Hosoi, Tadashi Nishimura, Ryota Shimokura, Tadashi Kitahara
It has been long considered that air and bone are the two major mediators that conduct sounds to the inner ear. In 2004, Hosoi found that vibration of aural cartilage, generated by placing gently a transducer on it, could create audible sound with the same level of clarity as air- and bone-conduction sound. He thus proposed the term "cartilage conduction" for this concept. This research identified a third mediator for sound conduction to the inner ear. Hosoi also proposed the development of novel communication devices, such as hearing aids, telephones, etc...
