Benign symmetric lipomatosis, also known as Madelung's disease, Launois-Bensaude syndrome and multiple symmetric lipomatosis is a cutaneous condition characterized by extensive symmetric fat deposits in the neck, shoulders, and upper trunk. But symmetrical lipomatosis of the tongue is very rare and characterized by involvement exclusively of the tongue, invasiveness, and absence of encapsulation of the adipose tissue. A 75-year-old man presented with about a year history of painless tongue masses on both lateral border. Bilateral partial glossectomy was performed and subsequently was confirmed as symmetrical lipomatosis pathologically. We report this case with a review of the literatures.

Schwannoma is a relatively uncommon, slow-growing benign tumor that is derived apparently from the Schwann cell. Tongue originated schwannomas are exceedingly rare within 1% and therefore often are not immediately included in the differential diagnosis and oral cavity tumors. In the current study, authors report a case of a schwannoma located at the tongue of a 49 years old patient treated by complete surgical excision. The patient is under clinical control, with no signs of recurrence even after 6 months.

This paper reports a patient who had an airway obstruction caused by a hemorrhage of the mouth floor that occurred after she underwent flapless implantation in the region of the mandibular anterior teeth. The hemorrhage may have been caused by iatrogenic malpositioned fixture and patient's hypertension. The lingual periosteum was not dissected during the flapless procedure. Therefore, when hemorrhage occurred, the blood did not drain easily into the oral cavity but instead drained into the deep neck region, which might have been the cause of the airway obstruction.

Malignant otitis externa (MOE) originates as inflammation of the epidermis in the external auditory canal, and spreads to the surrounding structures and neck, leading to abscess formation. MOE is associated with an immunosuppressive condition and diabetes. Patients with MOE suffer from otalgia, otorrhea and hearing loss. According to the literature, surgery to the temporomandibular joint is controversial as the treatment of choice.

The National Health Insurance Corporation has been retrieving from health care providers the payments made to them by insured patients as a result of the health care providers' arbitrary denial of coverage under the National Health Insurance, and has been disbursing such retrieved monies back to the patients, pursuant to Article 57, Sections 1 and 4 of the National Health Insurance Act. However, such practice is an application of the law that lacks legal exactitude. Another problem with such practice is that there is no legal provision under any laws or notices that expressly prohibits arbitrary denial of coverage. A legislative solution, therefore, is called for to address these issues.

Article 347 of criminal law provides the act of deceiving another, thereby taking property or obtaining pecuniary advantage from another. On the other hand, the concepts of fraud and abuse are confused upon interpretation since the definition in National Healthcare Insurance Law is unclear, and it affects closely to the administrative measures such as surcharge levy by the period of inspection, therefore, the disputes continue in the forms of formal objection, administrative ruling and administrative litigation. This study aims to look over the legal problems on application of criminal fraud toward the abuse of 'Paid Medical Expenses(Article 57, Sections 1 and 4 of the National Health Insurance Act)'. The main issues are concept of abuse(Article 57, Sections 1 and 4 of the National Health Insurance Act), the problems of Directions of Health-Welfare Ministry on aspect of 'Nullum crimen sine lege' Principles, the proper sentenc-ing guidelines of fraud.

Meningioma originates from arachnoid cap cells and is the second most common intracranial tumor; however, it can also be found in an extracranial location. A very rare primary extracranial meningioma without the presence of an intracranial component has also been reported. Primary extracranial meningiomas have been found in the skin, scalp, middle ear, and nasal cavity. A computerized tomography or magnetic resonance imaging scan is necessary to determine the presence or absence of an intracranial meningioma, and a biopsy is essential for diagnosis. We report a case of primary extracranial meningioma located in the forehead skin of a 51-year-old male.

Localized amyloidosis of the ureter is rare and clinically confused with neoplasm. We describe a case of localized amyloidosis of the ureter in which the presence of amyloid was detected in ureteral washing cytology. A 75-year-old female presented with gross hematuria. Abdominal CT and retrograde pyelography revealed hydronephrosis and hydroureter on the left side with abrupt narrowing of the distal ureter. Ureteral washing cytology yielded a hypocellular smear with many irregular clumps of amorphous, extracellar, waxy material. Biopsy sections demonstrated submucosal deposits of eosinophilic amorphous material which gave characteristic apple green birefringence with Congo-red stain under the polarized light. Familarity with the cytologic features of amyloid is helpful for preoperative diagnosis and proper treatment.

Intraparotid facial nerve schwannoma is a rare benign neoplasm. Due to its rarity, it is not usually a prioritized diagnosis before surgery and may therefore lead to an unintentional treatment error. In this article, we report a single case of intraparotid facial nerve schwannoma. We were able to make a diagnosis with frozen biopsy. A complete resection of the mass while preserving the facial nerve was performed. Herein we present our clinical experience with regards to the treatment process of intraparotid facial nerve schwannoma.

Liposarcoma is one of the most common malignancies originating from human soft tissue. Because most of liposarcoma occur in the lower extremities or retroperitoneum, there are few reports about liposarcoma of head and neck region, including larynx and pharynx. Histologically, there are four types of liposarcoma, and prognosis and recurrence rate are different according to histologic subtype. Wide excision is the treatment of choice and liposarcoma hardly respond to primary radiotherapy. A 56-year-old man presented with voice change and foreign body sensation in laryngopharynx. Hypopharyngeal liposarcoma was diagnosed by surgical biopsy and performed totallaryngopharyngoesophagectomy and gastric pull-up. Here we report our experience on this case with review of literature.
