Purpose: Extranodal marginal zone B cell lymphoma of MALT type represents approximately 8% of non-Hodgkin's lymphomas and this lymphoma is present in extranodal sites. Although the presentation of this lymphomain in stomach is usually associated with H. pylori infection in 95% of cases, MALT lymphoma found in soft tissue has been reported very rarely in the field of plastic surgery. We report a case of MALT lymphoma in the submandibular gland without any involvement of other organs such as the stomach. Methods: A 49-year-old man complained of a huge neck mass sized about $10{\times}12cm$. It started about 2 years ago and grew rapidly for the late 6 months. It was of hard nature with erythematous skin overlying it. Under the diagnosis of possible malignant lymphoma or sarcoma, radical resection was performed and the defect was reconstructed using transverse rectus abdominis musculocutaneous free flap. Results: The mass was well demarcated from the normal tissue, $11{\times}10.5{\times}10cm$ in size and whitish-gray color. Immunohistochemical analysis demonstrated that the tumor cells were LCA(+), CD20(+), CD3(-) and CD5(-). The tumor was diagnosed as extranodal marginal zone B cell lymphoma. The patient was treated with prophylactic radiation therapy after surgery, there was no complication for 1 year. Conclusion: We reported that very rare form of MALT lymphoma in 49-year-old male patient was experienced with clinical characteristics, histologic features and references.

Purpose: Congenital spinal dermal sinus tract is a rare lesion connecting skin to deeper structures including neural tissue. It results from the failure of the neuroectoderm to separate from the cutaneous ectoderm in the third to fifth week of gestation. The common locations are the lumbosacral and occipital regions. Sometimes it extends to spinal canal. In this paper we report a case of congenital spinal dermal sinus tract in the coccyx. Methods: A 21-month-old male child born after an uncomplicated full-term pregnancy was admitted to our institute with a midline dermal sinus and a cartilaginous protrusion in the coccygeal region. There were no signs of infection. Neurologic examination showed no functional deficit in both lower limbs. He was treated with complete excision of the tract and an underlying accessory cartilage. Results: The spinal dermal sinus tract was extended from the skin to the coccyx. The stalk was loosely attached to the accessory cartilage of coccyx. At that point, it was dissected from the accessory cartilage and resected. The accessory cartilage was also resected at the bone and cartilage junction. During the follow-up period of 6 months, the wound healed well without any complication nor recurrence. Conclusion: Congenital spinal dermal sinus tract is known as a form of spinal dysraphism. In order to prevent complications, timely surgical intervention including complete resection of sinus tract with correction of associated abnormalities is of utmost importance.

Malaria, caused by any of four species of protozoan parasites of the genus Plasmodium, is charaterized by high fever, anemia and splenomegaly. Although malaria is a cause of significant morbidity and mortality worldwide, in Korea indigenous malaria has been believed to be eradicated by 1984. However, since the case report of native malaria in 1993, reported cases have been increased annually, reaching more than 300 cases in 1996. We experienced a 2 years-old male with fever, severe anemia and splenomegaly who resided in Inchon city. He had the history of travelling to the area (Yunchon) near western Demilitarized Zone for 1 month this summer. After more than 2 weeks without special attention, he was presented with pallor, anemia and splenomegaly. He was diagnosed to have malaria by Plasmodium vivax with the help of peripheral blood smears which showed various forms of malaria, i.e., ring form, trophozoites, shizonts and gametocytes. He was treated successfully with hydroxychloroquine and primaquine. We report this case with brief review of related literature.

This report presents two cases concerning strategies for improving denture retention in pediatric patients with oligodontia caused by hypohidrotic ectodermal dysplasia (HED). Both patients presented with multiple missing teeth, conical canines, alveolar bone atrophy, and a skeletal Class III tendency. In the first case, a modified form of conical-crown-retained denture was used to cover the canines. This approach was carried out without tooth extraction or coping. In the second case of severe alveolar bone resorption and a distally tilted lower left canine, the tooth was restored with a hybrid ceramic crown. It was subsequently converted into a clasp-retained removable partial denture, utilizing a suction mechanism. Both patients are currently receiving regular check-ups for the maintenance of their prosthetic appliances and the evaluation of their growth patterns. This study presents innovative prosthetic treatment methods for pediatric patients with HED who have inadequate denture retention.

Leigh syndrome or subacute necrotizing encephalomyelopathy is a rare, rapidly progressive neurodegenerative disorder. In general, symptoms such as shortness of breath and decreased cardiac function usually occur within 1 year of life. It is a serious disease with a mortality rate of 75% in 2-3 years. The cause of Leigh syndrome is DNA mutation. Approximately 75% of patients have nuclear DNA mutations while 25% have mitochondrial DNA mutations. Clinical symptoms vary depending on the affected brain area. Neuroimaging plays an important role in diagnosing patients with Leigh syndrome. Late-onset Leigh syndrome is rarer and progresses more slowly compared to the classic form. Here, we report a case of late-onset Leigh's syndrome mimicking Wernicke's encephalopathy.

Objective: The purpose of this case study is to report the effectiveness of the Korean medicine Beewha-eum as a treatment for functional dyspepsia (FD). Methods: A patient diagnosed with a spleen-stomach deficiency-cold pattern in Korean medicine was treated with herbal medicines, including Beewha-eum. Symptom severity was assessed using the degree of self-reported dyspepsia (%), self-reported energy level, amount of food intake (%), total parenteral nutrition rate (cc/hour), body weight (kg), Nepean dyspepsia index (NDI-K), functional dyspepsia-related quality of life questionnaire (FD-QoL), and short form 36-item health survey (SF-36) score. Results: After treatment, the symptom severity of self-reported dyspepsia decreased from 100% to 10 to 15%, and the self-reported energy level increased from 20 to 80. The amount of food intake increased from 5% to 100%, and the total parenteral nutrition rate started from 60 cc/hour end in week 5. Body weight increased from 53.1 kg to 62 kg. The NDI-K score decreased from 105 to 31. The FD-QoL score increased from 19 to 68. The SF-36 score also increased from 102 to 116. Conclusion: The results suggest that the Korean medicine Beewha-eum could be an effective option for treating FD.

Myasthenia gravis is a disorder that affects neuromuscular transmission in a way that is still poorly understood. some think that myasthenia gravis results from a reduction of available acetylcholine receptors in neuromuscular junctions, consequent to some form of autoimmune injury. Surgical interest in this disease was first aroused in 1939 when Blalock observed that some patients with thymic tumors and myasthenia gravis improved following thymectomy. This report represents two cases of myasthenia gravis. The 14-year-old girl was admitted to Korea Universtiy Hospital with chief complaintment of bilateral ptosis, diplopia, swallowing difficulty, and mastication difficulty, which were relieved by administration of edrophonium (Tensilon) chloride, given intravenously. Myasthenica gravis was confirmed and thymectomy was given. After thymectomy, symptoms were relieved but the administration of neostigmine was contijued to be needed till following 3 months. After that period, she was free from this symptoms without anticholinesterase drugs. Second case is 57 year old male who has the symptoms of diplopia, bilatreal ptosis, walking disturbance, and speech difficulty. He had thymectomy too but in thymic tissue, malignant thymoma was included. He has subjective improvement only, with no major reduction of medication requirements after thymectomy.

Most tumors of the tracheobronchial tree are malignant, and benign tumors are less than 10%. Especially, the incidence of primary neurogenic tumors of the lung has been estimated to be less than 2 percent of primary lung cancer, and majority of these tumors are originated from Schwann cells. These tumors can be presented either as a solitary benign neoplasm or as a malignant form, which is rare. We present two cases of bronchial Schwan noma managed by means of lobectomy.
