Myoepithelioma was recognized as a histological distinct entity by the World Health Organization (WHO) in 1991. Myoepithelial cells are believed to be of ectodermal origin. In salivary glands, the myoepithelial cells that surround the intercalated ducts are spindled, which is in contrast to the large stellate ones that envelop the acini. Myoepithelioma is a benign salivary gland tumor that consists entirely of myoepithelial cells. A 53-year-old man presented with a 1-year history of a painless mass originating from the right parotid gland. The mass grew rapidly reaching a size of approximately 6 cm. The patient had no facial paralysis. The authors performed right parotidectomy. Immunohistochemistry study of this tumor showed that it was positive for vimentin, positive for S-100, focally positive for pancytokeratin, and focally positive for p63 and that it had a Ki-67 labeling index (below 10%). Additionally, the tumor was negative for epithelial membrane antigen, negative for actin, negative for desmin, negative for CD34 and negative for anaplastic lymphoma kinase. The authors present a case of benign spindle cell myoepithelioma of the parotid gland in a 53-year-old man diagnosed after immunohistochemistry study, describing its importance, along with a brief review of the literature.

Mycobacterium abscessus comprises rapidly growing mycobacteria, and the clinical manifestations of M. abscessus skin infection include papule, nodule, ulcer, scar and mixed form. The cutaneous infections have been reported due to minor trauma, cosmetic therapy, acupuncture and disseminated infection. A 75-year-old man presented with pruritic diffuse various sized erythematous papuloplaques and pustules on the neck and chest for 2 months. The cutaneous lesions were spread around the wound of the shaving on the neck. The histopathologic findings were consistent with abscess showing infiltrations of neutrophils and lymphocytes in the dermis and negative findings were observed on immunohistochemical stain including acid-fast bacilli stain. One month later, mycobacterial culture result showed positive findings, and the pathogen was identified by reversetranscriptase polymerase chain reaction with hybridization. The patient was treated with combination of clarithromycin and ethambutol for 5 months and there is no evidence of recurrence after 6 months of follow-up. Herein, we report a case of M. abscessus cutaneous infection through minor trauma caused by shaving in the elderly.

Primary cutaneous mucinous carcinoma (PCMC) is a rare malignancy of the sweat glands that most commonly affects the periorbital area. It is characterized by slow growth over a prolonged period, and its morphology can be easily confused with a benign tumor, such as an epidermal cyst. Consequently, many patients experience recurrence after undergoing multiple resections. However, there are few reports concerning the surgical management of PCMC. We present two cases of PCMC originating in the periorbital area. The first case involved a 76-year-old man with a mass measuring 3.0×1.5 cm that had been increasing in size. The second case was a 61-year-old man with two masses, each measuring 1.0×1.0 cm, that were also growing. Both patients underwent wide excision with a 5-mm safety margin, which was determined based on the widest view of the cross-section of the mass on the magnetic resonance imaging. Subsequently, based on the intraoperative frozen biopsy results, both patients underwent additional excision with a 5-mm safety margin in only one direction. This report shows that, when determining the surgical margin of PCMC in periorbital area, employing imaging modalities and intraoperative frozen biopsies can be helpful for narrowing the surgical margin.

Through this thesis, I analyzed Coen brothers's directing style centering around Crime movies: Blood simple, Barton Fink, Fargo, The man who wasn't thers, No country for old man. About directing style of Coen brothers, plot is an epic depiction, habitual use of narration, refusal of happy ending. They concern subject matters about human original nature and tragedy by greed. And as motifs, they often use misunderstanding, crossing over, chase. Also they likes characters of ordinary people who is destroyed by greed. How about their technical style? They usually use steady-cam and wide lens in camera, and in his early crime movies he used expressionistic lights, but after that they usually used realistic natural lights. About sound, they likes more sound effects than music. Also they directed realistic acting and emphasized actor's personality. Coen brothers has been directed many crime movies and comedy films. But their unique directing style was particularly outstanding in the crime movies

Two cases of an anomalous systemic arterial supply to the basal segments of the left lower lobe without pulmonary sequestration are presented. In the first case, a preoperative diagnosis was made by chest CT, and confirmed by angiography, in a 22-year old man who had a recurrent hemoptysis. There was systemic arterial supply that originated from the thoracic descending aorta and no pulmonary arterial supply to the basilar segments of the left lower lobe. However, the pulmonary parenchyma was normal without sequestration. Ligation of the abnormal artery and a left lower lobectomy were performed without complications. In the second case, there were characteristic features of this anomaly on chest CT and the angiogram in a 31-year-old man with symptoms of hemoptysis. The patient refused surgery.

Pulmonary thromboembolism occurs in old patients with risk factors, such as, immobilization, chronic medical disease, trauma, a hereditary hypercoagulable state, and others. However, we experienced a young man with a massive pulmonary thromboembolism attributed to immobilization due to computer gaming. The patient had been playing computer games in a seated position for at least five hour continually, and for twelve hours per day over a two-week period. The 36-year-old patient was transferred to our institute rule out the possibility of an acute myocardial infarction. Computer tomography revealed intraluminal filling defects in the distal main pulmonary artery and the left popliteal vein. He received thrombolytic therapy and subsequently recovered without complications. This case raises the possibility that prolonged computer gaming is a risk factor of thromboembolism in young adults.

Objectives : To report three cases of eye movement impairment: internuclear ophthalmoplegia (INO) due to pontine infarction, traumatic abducens nerve palsy, and abducens nerve involvement in Miller-Fisher syndrome. Cases Summary : There were three cases. First, a 64-year-old woman, who was given a diagnosis of INO due to pontine infarction, had left gaze palsy of her right eye while the convergence was intact. Second, a 34-year-old man had abduction impairment of his right eye after a traffic accident. Third, a 66-year-old man, who was diagnosed with Miller-Fisher syndrome, had left gaze palsy of his left eye. Their symptoms improved substantially and their anxieties were relieved after treatment with herbal medicine and acupuncture. Conclusions : There has been no certain cure for eye movement impairment yet. In this report, we present three successful cases of patients with eye movement impairment and show that Korean medical treatment could be a solution for this incurable disease.

Objective : The authors present three cases of brain tumors in which epidural hematomas(EDHs) were developed postoperatively in the remote areas from craniotomy sites. The preventive tactics as well as possible mechanisms of development of remote EDH are discussed. Material and Methods : The magnetic resonance imagings of three patients revealed a left lateral ventricular mass located just aside of foramen Monro in a 27-year-old male, a large cystic mass in the temporal lobe in a 35-year-old male, and a partially calcified pineal mass in a 27-year-old male patient. The surgical removals of these tumors were performed without any noticeable events during surgery via left frontal transcortical transventricular approach for lateral ventricular tumor, left temporal craniotomy for cystic temporal tumor, and right occipital transtentorial approach for pineal tumor. Results : Postoperative EDHs remote from the sites of craniotomy were detected by the immediate postoperative computerized tomographic scans. We obtained good outcomes without any morbidity in all three patients with emergent evacuation of the hematoma. The pathologic diagnoses were lateral ventricular ependymoastrocytoma, temporal craniopharyngioma and mixed germinoma of the pineal region. Conclusion : It is postulated that a sudden reduction of intracranial pressure(ICP) at the time of tumor removal may strip the dura from the inner table of the skull to cause EDH from the remote site of craniotomy. Gradual reduction of ICP with slow drainage of cerebrospinal fluid before tumor removal as well as lowering the head position of patient during surgery might be helpful for preventing this unusual complication.

Pemphigus vulgaris (PV) is a chronic autoimmune bullous disease caused by autoantibodies to proteins in the oral mucosa and skin. It is a rare disease with an annual incidence of 2.059 per million in South Korea. In many patients with PV, oral mucosal lesions precede other lesions elsewhere, and oral lesions can be the only manifestation. Early diagnosis is important because the disease has a high mortality rate if untreated appropriately in the early stages, and rapid treatment initiation is associated with rapid disease control. Oral PV lesions are clinically variable. In this study, we describe oral PV lesions in a 60-year-old woman, a 75-year-old man, and a 60-year-old man presenting with various clinical presentations. Oral PV lesions can affect any part of the oral mucosa, including the buccal mucosa, gingiva, tongue, palate, and free mucosa, and can vary in appearance from desquamative gingivitis, painful ulcers, and erosions to aphthous-like stomatitis. Clinicians should be aware of the difficulty of early diagnosis in PV, particularly when oral lesions are the only manifestation, and should consider many factors, including the patient's age, to make an accurate diagnosis and manage oral lesions to improve the patient's quality of life and avoid delayed diagnosis.
