Pulmonary epithelioid hemangioendothelioma (PEH), originally termed an intravacular bronchioloalveolar tumor, is a rare pulmonary neoplasm with a vascular origin and slow rate of malignancy. It affects various organs such as the liver, the central nervous system, lung, etc. Clinically, pulmonary epithelioid hemangioendothelioma has been considered to be a borderline malignancy, a generally indolent and nonaggressive tumor that displaes the pulomonary parenchyma over a number of years by slowly enlarging the tumor nodule. The clinical course of PEH is known to be usually benign. Here we report an unusual case of PEH that was highly malignant and was eventually fatal. The PEH was confirmed by microscopic analysis and hmmunohistochemical staining of CD31+(a membrane receptor and a sensitive and specific marker for vascular lesions) from an open lung biopsy specimen.

BACKGROUND/AIMS: SCN5A encodes the cardiac-specific NaV1.5 sodium channel, and Brugada syndrome is a cardiac conduction disorder associated with sodium channel alpha-subunit (SCN5A) mutation. The SCN5A-encoded NaV1.5 channel is also found on gastrointestinal smooth muscle and interstitial cells of Cajal. We investigated the relationship between functional dyspepsia (FD) and SCN5A mutation to evaluate sodium channelopathy in FD. METHODS: Patients with Brugada syndrome or FD were examined using upper endoscopy, electrogastrography (EGG), FD symptom questionnaire based on Rome III criteria and genetic testing for SCN5A mutation. Symptom scores of FD and EGG findings were analyzed according to SCN5A mutation. RESULTS: A total of 17 patients (4 Brugada syndrome and 13 FD) participated in the study. An SCN5A mutation was noted in 75.0% of the patients with Brugada syndrome and in 1 (7.7%) of the patients with FD. Of 4 patients with SCN5A mutation, 2 (50%) had FD. Postprandial tachygastria and bradygastria were noted in 2 (50%) and 1 (25%) of the patients with SCN5A mutation, respectively. The EGG findings were not significantly different between positive and negative mutation in 17 patients. CONCLUSIONS: Although we did not find statistically significant results, we suggest that it is meaningful to attempt to identify differences in symptoms and gastric myoelectric activity according to the presence of an SCN5A mutation by EGG analysis. The relationship between FD and sodium channelopathy should be elucidated in the future by a large-scale study.

Primary malignant melanoma of the esophagus(PMME) is an extremely rare but aggressive disease that composes less than 0.1% of all primary malignant neoplasm of the esophagus. PMME was first reported in 1906 and nearly 180 cases of primary esophageal malignant melanoma have been published in the medical literature. Symptoms of the primary malignant melanoma of the esophagus mimic that of any malignant obstructing lesion of the esophagus and the metastatic spread by lymphatics and vascular routes are common. Resection of the tumor with an anastomotic procedure seems to be the treatment of choice, however prognosis is poor. At present, chemotherapy and immunotherapy have no major role in treatment. We report a case of 67-year-old man with primary malignant melanoma of the esophagus originated from esophageal melanosis with a review of the literature.

OBJECTIVES: We compared the effects of a 1,500 ppm fluoride-containing toothpaste and a 1,000 ppm fluoride-containing toothpaste, which were revised up to the recent revision, and evaluated their effects on the tooth surface after adding bamboo salt to the preparations. METHODS: Experimental early artificial caries specimens were subjected to one of four treatments (n=12 per treatment group): 1,500 ppm NaF, 2% bamboo salt+1,000 ppm NaF, 1,000 ppm NaF, and control treatment. The specimens were exposed to the experimental toothpaste, artificial saliva, and demineralized solution. The treated specimens were analyzed using Vickers surface hardness testing, scanning electron microscopy, and atomic force microscopy. RESULTS: The toothpaste with a high fluoride concentration (1,500 ppm NaF) showed more remineralization than did the toothpaste with a low fluoride concentration (1,000 ppm NaF). The 2% bamboo salt+1,000 ppm NaF group showed remineralization similar to the 1,500 ppm NaF group and higher surface microhardness than the 1,000 ppm NaF group. CONCLUSIONS: Toothpastes containing 1,500 ppm NaF have a higher preventive effect against dental caries than do toothpastes containing 1,000 ppm NaF. The addition of bamboo salt to fluoride-containing dentifrices improves their effectiveness in preventing dental caries.

Barth syndrome (BTHS) is a rare genetic disorder characterized by various types of cardiomyopathy, neutropenia, failure to thrive, skeletal myopathy, and 3-methylglutaconic aciduria. BTHS is caused by loss-of-function mutations in the tafazzin (TAZ) gene located on chromosome Xq28, leading to cardiolipin deficiency. We report a 13-month-old boy with BTHS who had a novel de novo mutation in the TAZ gene. To the best of our knowledge, this is the first reported case of a BTHS patient with a de novo mutation in Korea. This report will contribute towards expanding the knowledge on the mutation spectrum of the TAZ gene in BTHS.

Schwannomas are benign nerve sheath tumors that originate from any anatomical site. Most schwannomas occur in the head, neck or limbs, but rarely occur in the retroperitoneal space. Furthermore, the schwannoma originating from the vagus nerve of retroperitoneal space is much rare. We experienced a case of retroperitoneal schwannoma of the vagus nerve. A 34-year-old male was refered to our hospital for the evaluation of abdominal mass on ultrasonography. Endoscopic examination revealed submucosal tumor-like lesion on high body of the stomach. Computed tomography (CT) revealed that the stomach was compressed by a solid tumor in the retroperitoneum. On exploratory laparotomy, this mass turned out to be a baseball sized mass in the retroperitoneal space. The mass was excised in an encapsulated state. Histological examination with immunohistochemical stains revealed a schwannoma of the vagus nerve.

Sump syndrome is one of the late complications of a side to side choledochoduodenostomy, but it is a rare malady. The anastomosis of the bile duct and small bowel results in exclusion of the distal limb of the common bile duct from drainage of bile with the potential formation of a sump. Food material and bile sludge may accumulate in distal segment of common bile duct and so this cause recurrent bile duct stones. Bezoars frequently result from disturbed passage of the gastrointestinal tract, especially after surgery, and it may develop various symptoms by irritating or obstructing the gastrointestinal tract. The bezoar accompanied with sump syndrome after choledochoenterostomy has not yet been reported in the literature. We report here on a case of small intestinal obstruction due to bezoars accompanied with sump syndrome.
