Proliferating trichilemmal tumor is one of rare benign tumors of the skin appendages, considering as hamartoma of the terminal hair follicle, isthmic segment of the outer root sheath. We report a case of numerous proliferating trichilemmal tumors admixed with ordinary trichilemmal cysts with femilial history in 64-year-old man. He has total 157 lesions, which are chiefly located in scalp (48), back (32), and also face, neck, trunk, extremities. Histologically, the tumor is composed of irregularly arranged and ansatomosed trabeculae, lobules, or sheets of proliferated trichilemmal squamous epithelium with peripheral palisading of the basaloid cells. Several layers of squamoid or ovoid cells have PAS-positive clear cytoplasm. And it also shows abrupt amorphous, trichilemmal keratinization. Some squamous eddies with mild cellular atypism are associated, but definite invasion or other evidence of the malignancy is not found. usual multiple trichilemmal cysts are admixed with tumor and occasionally exhibit connection between them.

Cytophagic histiocytic panniculitis is a rescently described histiocytic disorder. It is characterized by the presence of fever, pancytopenia, and subcutaneous nodules resulting from the infiltration of lympho-histiocytes in the dermis and subcutaneous adipose tissue. The characteristic findings is presence of bean-bag histiocytes containing phagocytized red blood cells, lymphocytes, and platelets. We experienced two cases of cytophagic histiocytic panniculitis with hard and erythematous subcutaneous nodules. These skin lesions exhibited infiltration of the subcutaneous tissue by large, benign histiocytes with cytophagic features. Hemophagocytic histiocytes were observed in the cervical lymph node in case 1, and bone marrow in case 2. One patient is alive, while the other one died with hemorrhagic complications.

PURPOSE: NPI (Nottingham prognostic index) including tumor size, lymph node status and histological grade is widely used for the estimation of prognosis in breast carcinomas, and recently, the immunohistochemical index (IHPI) using ER, PR, c-erbB-2, and p53 expressions was suggested as an useful prognosticator. The aim of this study is to evaluate the reliability of NPI and IHPIs in 141 breast carcinomas. METHODS: Statistical analysis among size, lymph node status, histological grade, NPI, ER, PR, c-erbB-2, p53 and MIB-1 labelling index(LI) and IHPIs were performed. The IHPI-1 battery consisted of ER, PR, c-erbB-2 and p53. In the IHPI-2 battery, MIB-1 LI was added to the IHPI-1 battery. In the IHPI-3 battery, MIB-1 LI was also added, but ER and PR were not included. RESULTS: The prognostic estimation based on NPI showed significant relationships with PR, c-erbB-2, MIB-1, and the prognostic estimations according to IHPI-1, IHPI-2 and IHPI-3 battery. In addition, MIB-1 LI revealed a positive relationship to the histological grade. The prognostic estimation based on IHPI-3 showed a positive relationship to the lymph node status. CONCLUSION: The prognostic estimation based on NPI and a battery of immunohistochemical stains consisted of c-erbB-2, p53 and MIB-1 seem to be reliable in breast carcinomas.

OBJECTIVE: To investigate whether polymorphism of Catechol-O-methyltransferase (COMT) gene is associated with the risk of polycystic ovary syndrome (PCOS) in Korean women. METHODS: One hundred and thirty-six PCOS patients and eighty four controls were enrolled. Blood samples were collected from the patients diagnosed according to the 2003 revised criteria of the Rotterdam ESHRE/ASRM-sponsored PCOS consensus workshop group. Age matched women with regular menstruation from same geographic region were recruited as control subject. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) of PCR products were done to determine all individuals' genotype. RESULTS: In women with COMT(LL) genotype, there was decreased PCOS risk and this difference was statistically significant (OR 0.24, 95% CI 0.11~0.51). CONCLUSION: The results suggest that the COMT(LL) genetic polymorphism might be associated with PCOS risk in Korean women.

PURPOSE: This study aimed to investigate the academic achievement and first-time experience with TBL in Year 1 medical graduate students through a medical dermatopathology lecture at Konkuk University School of Medicine. METHODS: 47 students prepared the objective-oriented assignment and completed an individual readiness assurance test, a group readiness assurance test, and a application exercise. Peer evaluation was done. At the completion of the lecture, the students were surveyed about their experiences. The scores from the TBL session activities and students' survey results were analyzed. The tutor's comment about TBL session was analyzed. RESULTS: Overall, TBL was helpful for the medical graduate students in understanding the dermatopathology lecture. Students' perception on their TBL experience was positive.They stayed focused on the activity and showed excellent teamwork. CONCLUSION: We allowed medical students to experience TBL through a dermatopathology lecture and then summarized their experience. This study demonstrates that TBL is an effective active teaching method for teaching dermatopathology.

The intracranial meningioma associated with hidden cerebral aneurysm is rare. We experienced a patient with subarachnoid hemorrhage (SAH) due to the rupture of cerebral aneurysm during intracranial meningioma removal, although preoperative 6-vessel angiographic study did not reveal aneurysmal dilatation. During operation, tumor was resected piece by piece, and totally removed, grossly. After removal of tumor, the brain swollen suddenly along with hypertension and bradycardia suspecting Cushing's reflex was developed. Emergent postoperative CT and CT-angiographic study revealed large amount of SAH and ruptured aneurysmal dilation of A3 segment of anterior cerebral artery. She died from brainstem failure on 4th postoperative day. We report a rare case of anesthesia for coexisting intracranial meningioma and intracranial aneurysm.

A food exchange system for diabetes is a useful tool for meal planning and nutritional education. The first edition of the Korean food exchange lists was developed in 1988 and the second edition was revised in 1995. With recent changes in the food marketplace and eating patterns of Koreans, the third edition of food exchange lists was revised in 2010 by the Korean Diabetes Association, the Korean Nutrition Society, the Korean Society of Community Nutrition, the Korean Dietetic Association and the Korean Association of Diabetes Dietetic Educators through a joint research effort. The third edition is based on nutritional recommendations for people with diabetes and focuses in adding foods to implement personalized nutrition therapy considering individual preferences in diverse dietary environment. Foods were selected based on scientific evidence including the 2007 Korea National Health and Nutrition Examination Survey data analysis and survey responses from 53 diabetes dietetic educators. While a few foods were deleted, a number of foods were added, with 313 food items in food group lists and 339 food items in the appendix. Consistent with previous editions, the third edition of the food exchange lists included six food categories (grains, meat, vegetables, fats and oils, milk, and fruits). The milk group was subdivided into whole milk group and low fat milk. The standard nutrient content in one exchange from each food group was almost the same as the previous edition. Korea Food & Drug Administration's FANTASY(Food And Nutrient daTA SYstem) database was used to obtain nutrient values for each individual food and to determine the serving size most appropriate for matching reference nutrients values by each food group. The revised food exchange lists were subjected to a public hearing by experts. The third edition of the food exchange lists will be a helpful tool for educating people with diabetes to select the kinds and amounts of foods for glycemic control, which will eventually lead to preventing complications while maintaining the pleasure of eating.

Neuroendocrine tumors originate from neuroendocrine cell, so called APUD (amine precursor uptake and decarboxylation). Most neuroendocrine tumors have typical histopathology, immunohistochemical findings, and can be diagnosed by specific electromicroscopic feature of dense core granules. Neuroendocrine tumors are a diverse group of neoplasms that include carcinoid tumors, islet cell tumors, neuroblastoma, and small cell carcinoma. Neuroendocrine carcinoma of thymus bears similarities to neuroendocrine carcinoma in other organs, but it is clinicopathologically distinct from other tumors of thymus. Rare reports have been seen about thymus neuroendocrine carcinoma. Authors experienced a case of neuroendocrine carcinoma of thymus which cannot be classified as carcinoid, atypical carcinoid, or small cell carcinoma. Herein, we report this case with a review of the literatures.
