The fatty hamartoma of pericardium is characterized by abnormal accumulations of adipose tissue forming a recognizable mass. We reported a case that could best be put into "fatty hamartoma" group. This 66 year old male presented with atrial fibrillation came in for a anterior mediastinal mass. He received an operation for adenocarcinoma of ascending colon several months ago. The chest CT revealed an inhomogeneous mass in the right anterior mediastinal area, which was not clearly demarcated from the right cardiac border. The heart was deviated to the left side due to the mass. Surgical excision was performed under the impression of cardiac teratoma. The large mass was well encapsulated, and was bright yellow and partly pink, and measured 12x8 cm. Microscopically, the mass consisted predominantly of mature fat cells and abundant fibrous tissue with scattered nests of primitive cardiac muscle cells. Reviewing the literature we found the term "fatty hamartoma" could also refer to rhabdomyolipoma or fibrolipoma. Since it contains entrapped cardiac muscle cells, abundant fibrous tissue, multiple blood vessels and fetal fat cells, it could best the categorized into "hamartoma". The term "fatty" represents it's main component. Therefore we propose the term "fatty hamartoma" that could to be used further.

Cognitive deficit is frequently observed in patients with schizophrenia. It is significantly associated with functional outcome. In the past 20 years, due to significant advances on the concept of schizophrenia, cognitive deficit has been accepted as a core feature. In the DSM-5, cognitive deficit does not introduce diagnostic criteria of schizophrenia, but did one dimension of diagnosis of psychosis. Existing schizophrenia drugs are effective in treatment of positive symptoms of schizophrenia, but lack of effectiveness on improving cognitive function. Led by NIMH (National Institute of Mental Health), the MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophrenia) meeting was conducted in order to achieve consensus on measuring tools and neuropharmacological targets for clinical trials for development of new drugs for improvement of cognitive function in schizophrenia. At the MATRICS consensus meeting, glutamatergic modulators and nicotinic and muscarinic agonists are expected to be promising, but should be proven by a double-blind placebo-controlled multicenter study for patients.

Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.

5.A Clinical Analysis of Well-Differentiated Thyroid Cancer.
Journal of the Korean Surgical Society 1999;56(6):807-813
BACKGROUND: Thyroid cancer is the most common endocrine malignancy, and it has a wide spectrum of biologic behavior, histologic appearance, and management. This study reviewed various aspects of the clinical features of well-differentiated thyroid cancer. METHODS: We retrospectively reviewed the clinical characteristics of 114 patients who had undergone surgical management for well-differentiated thyroid cancer at the Chonbuk National University Hospital from September 1989 to December 1997. RESULTS: The most prevalent age group was in the 5th decade (29 cases, 25.4%). The male-to-female ratio was 1 to 5.7. The most common initial symptom was a palpable mass on the anterior or the lateral portion of the neck (110 cases, 96.5%). The most common duration of illness from the appearance of the symptom to the treatment was below 3 months (38 cases, 34.5%). The primary tumors were located on the right lobe (49 cases, 43.0%), the left lobe (38 cases, 33.3%), both lobes (22 cases, 19.3%), and the isthmus (5 cases, 4.4%). In the histopathologic study, the common type was a papillary carcinoma (102 cases, 89.5%). The common surgical procedures were a total thyroidectomy (66 cases, 57.8%) and a near total thyroidectomy (24 cases, 21.0%). Seventy-five patients (65.8%) received a lymph-node dissection, and there was cervical lymph-node metastasis in 43 cases (57.3%) of this group. Postoperative complications occurred in 11 cases (9.3%). The common complications were hemorrhage or seroma (5 cases, 4.4%), hoarseness (5 cases, 4.4%) and wound infection (1 case, 0.9%). Although hypoparathyroidism was predicted, the predominant symptoms did not appear. Regional recurrence or distant metastases were present in 13 cases (11.4%) during four years. CONCLUSIONS: Thyroid cancer has a wide spectrum of biological behavior and also problems including the lack of reliable prognostic factors and objective assessments of therapeutic modalities. Appropriate and aggressive management should be recommended because most of well-differentiated thyroid cancer has a favorable prognosis.

Deep skin and soft tissue defects with exposed bone and tendon is difficult to treat, because skin graft rarely survives and flap surgery is sacrifice of donor site. Since "Stage I" membrane was developed by Yannas and Bruke in 1980, numerous kinds of artificial skin have been developed. The adaptability of "Terudermis", developed by the Terumo Co., as an artificial skin composed of sponge made of a fibrillar atelocollagen and a heat-denatured atelocollagen, was clinically evaluated on application to 13 cases presenting deep skin and soft tissue defect with exposed bones and tendons from October 1997 to march 1998. Terudermis has the advantage of allowing early incorporation of fibroblasts and capillaries into its collagen sponge due to very weak dehydrothermal cross-linking. Before Terudermis graft, several days of wet dressing and debridement were required to prepare healthy well-vascularized bed because Terudermis was weak on unsanitary wounds. After bed preparation, Terudermis was grafted like usual skin graft. Tie-over bolster dressing or compressive dressing was used case by case. The dressing was opened 2~3 days after Terudermis grafting. Wet dressing was done daily until the skin graft was done. Autologous skin graft was done 2-3 weeks after Terudermis graft. Our clinical results indicated that Terudermis was beneficial in treating 77% of our patients. Through the use of this new method, treatment of severe skin and soft tissue defects that are usually treated by musculocutaneous or other conventional skin flaps can be replaced by Terudermis as an new artificial dermis.

9.Clinicopathologic Study of Pulmonary Fat Embolism in Fatty Liver.
Tae Jung KWON ; Hyun Wook KANG
Korean Journal of Legal Medicine 2001;25(1):44-49
Fat embolism is the presence of fat globules in the peripheral circulation and in the lung, brain, kidney, heart, and so on -not in the fine emulsion of a metabolic lipemia but in globules large enough to obstruct arterioles and capillaries. The fat droplets can derive from fractures of long bone due to disruption of the fatty marrow, from extensive bruising of the soft tissue, and from fat tissue in burns. Fat embolism has also been reported in patients suffering from various diseases including alcoholism, fatty liver, diabetes mellitus and pancreatitis. We investigated 19 autopsies with fatty liver of varying degrees to establish a correlation between fatty change of liver and pulmonary fat embolism. Among 19 cases, 3 cases with moderate to severe fatty change of liver, and 1 case with submassive hepatic necrosis and mild fatty change showed Grade II pulmonary fat embolism. In histologic section with Sudan III stain, the arteries and capillaries of lung were occupied and distended by round, oval, or staghorn fat globules. The alveoli may contain edema fluid and blood. Although the pulmonary fat embolism occuring in the presented cases didn't cause death on its own, one should be aware that a life-threatening mobilization of fat into the lungs and even into the systemic circulation is possible in fatty liver and submassive hepatic necrosis.
