Epithelioid smooth muscle tumor is relatively rare and potentially malignant, especially in retroperitoneum. Distinct criteria for malignancy still have not been clarified in this epithelioid variant arising in retroperitoneum. We report a deceptively benign-appearing epithelioid leiomyosarcoma in a 50-year-old female. She was admitted with abdominal discomfort and dysuria. Abdominal CT showed a well-demarcated, 10 10 cm sized, solid mass in retroperitoneum. Concomitant metastatic lesions were noted in right lung field. Surgical excision of retroperitoneal mass and right lung lobectomy were performed. The retroperitoneal mass showed yellowish-tan, well-delineated and lobulated appearance. Histologically, this tumor was composed of predominantly epithelioid, round to oval cells with distinct clear cytoplasm and slightly atypical nuclei. Mitosis was rare (0~1/50 HPF). Lung lesions were morphologically similar to that of retroperitoneum.

Acral lentiginous melanoma is a rare variant of malignant melanoma and is characterized by a lentiginous (radial) growth phase that evolves over months or years to a dermal (vertical) invasive stage. Clinical and pathological features were reviewed in 3 cases of acral lentiginous melanoma of the soles. The first case was a 59-year-old female. On gross examination, there was a black, nodular, round, and ulcerated mass, 1.5 x 1.5 cm, on the posterior portion of the left sole. This mass was accompanied by peripheral pigmented macules. Histologically, the macular lesion revealed the pattern of a lentiginous growth phase, with a diffuse hyperplasia of atypical melamocytes in the basal layer of the epidermis. In the vertical growth component, atypical melanocytes (predominantly spindle cell) infiltrated the dermis, showing level 3 invasion. The second case was a 47-year-old male. On gross examination, there was a dark brown to black, nodular, hemorrhagic and ulcerated mass, 7x7 cm, on the middle portion of the right sole. This mass grew radially into neighboring tissue. Histologically, the radial growth component revealed atypical melanocytes which were distributed in the basal portion of epidermis. In the vertical growth component, atypical melanocytes (spindle, round, or polygonal cells) infiltrated the dermis, showing level 4 invasion. The third case was a 87-year-old female. There was a formation of satellite pigmented macules, up to 2x0.5 cm, on the right sole. The color of macules was usually not uniform but was likely to be scattered radially, being grayish brown, bluish black, or black. Histologically, the peripheral, macular, hyperpigmented lesion revaled the pattern of a lentiginous growth phase. In the vertical growth component, atypical melanocytes (predominently polygonal cells) infiltrated the dermis, showing level 13 invasion.

Background and Objective : Dural sinus thrombosis(DST) is a rare disorder with many etiologies and unpredictable clinical courses. The optimal mode of treatment has not been well established. With the advent of neuroradiological intervention, we have successfully performed the direct infusion of t-PA into the venous sinus for the prompt Iysis of thrombosis and subsequent clinical Improvement. METHODS: Three patients, presented with headache, vomiting or focal neurological deficits, were diagnosed as having dural sinus thrombosis by MRI. After the confirmation by angiogram with a superselective transfemoral catheter, a bolus of t-PA was injected into the thrombosed portion of the dural sinuses, followed by a continuous t-PA infusion at a rate of 40mg/hr. Result : All three patients were clinically improved. Follow-up angiogram on the next day demonstrated recanalization of the thromboses venous sinus. Two patients developed non-life threatening extracranial hemorrhage as a complication. Conclusion : Authors suggest that direct thrombolysis with t-PA is a very effective method of treatment in the early phase of DST. Further study is needed to decide the appropriate t-PA dosage to minimize the complication.

4.The Tendinous Slip of the Flexor Digitorum Longus for the Great Toe: An Anatomic Variation.
Korean Journal of Physical Anthropology 2017;30(2):61-65
This report describes a variation of the tendinous slip of the flexor digitorum longus (FDL) for the great toe. In addition, compositions of the long flexor tendons for all five toes were examined. The tendons of the FDL in the foot were investigated in 66 specimens of embalmed Korean adult cadavers. The tendons of the flexor hallucis longus (FHL) and the FDL with the lumbrical muscles were cut at the calcaneus and the metatarsophalangeal joints and were removed en bloc specifically to observe the FDL and the FHL tendons of the great toe. The tendinous slip of the FDL for the great toe was found bilaterally in the foot of a 52-year-old male. Its prevalence was two of 66 specimens (3.0%). The tendinous slip of the FDL for the great toe passed forward the great toe, and it constituted the superficial portion of the long flexor tendon for the great toe. The tendon of the FHL passed forward to constitute the deep portion of the long flexor tendon for the great toe. Thus, both the tendinous slip of the FDL and the tendon of the FHL composed the long flexor tendon for the great toe. The tendinous slip of the FDL and the tendon of the FHL for the great toe were similar in thickness; thus, each tendinous slip of the FDL and the tendon of the FHL were approximately one-half of the long flexor tendon for the great toe in thickness. The present study demonstrated an anatomical variation of the interconnection between the FHL and the FDL tendons, which will be useful for various surgeries and biomechanical research.

5.What Qualities Do Medical School Applicants Need to Have? : Secondary Publication.
Yonsei Medical Journal 2009;50(3):427-436
PURPOSE: Doctors are asked to play the roles of both a healer and a professional. In dealing with this inherent demand, we should first ask ourselves if we are selecting students who show traits that would enable them to become a good doctor. The primary concern of this study was to identify the core elements of medical professionalism that will develop into professional competence that we should be sought in medical school applicants. MATERIALS AND METHODS: One hundred-six responses from the Delphi survey done by medical school professors and 230 completed questionnaires from medical students were used for analysis. We also set out to analyze the level of medical professionalism in newly entering medical students using a 5-point Likert scale. RESULTS: Of the 27 elements of medical professionalism examined, the most important core element was thought to be 'life-long learning skills'. The level of professionalism in Korean medical students was mostly assessed to be less than the 3.0 mean score given by the professors. Medical students tended to rate themselves higher than did the professors for their level of medical professionalism. CONCLUSION: Medical professionalism can be categorized into three domains; professional knowledge, professional skills, and professional attitude. For the prominent differences in the recognition of the levels of professionalism elements in medical students by students and professors, further studies investigating the reasons for discrepancy are needed.

7.How to provide tailored career coaching for medical students.
Korean Journal of Medical Education 2015;27(1):45-50
PURPOSE: This study was performed to develop a counseling strategy, based on the profiles of medical students' Strong Interest Inventory (STRONG) and Myer-Briggs Type Indicator (MBTI) results, focusing on the three following questions: Into what distinct levels are students categorized by STRONG and MBTI? and What is the dispersion of the integrated profiles? METHODS: Freshmen students from Konyang University College of Medicine who matriculated between March 2011 and 2013 were administered the MBTI personality type test and the STRONG interest inventory assessment. The integrated profiles were categorized per Kim et al. (2006), and frequency analysis was performed with the collected data, using SPSS version 21.0. RESULTS: Regarding MBTI types, 16.9% of students were categorized as ESTJ, and 12.9% was ISTJ. Further, 62.4% of students were Investigative (I) according to STRONG. The integrated profiles were divided into four types, according to their unclear/clear preference in the STRONG and MBTI results. Most students had 'clear preference and clear interest' (n=144, 80.9%), six students (3.4%) had 'clear interest but unclear preference,' and 28 students (15.7%) showed 'unclear interest but clear preference.' CONCLUSION: Using the combined results of the STRONG interest inventory assessment and MBTI tools, we can purvey more tailored information to students.

8.The characteristics of medical students' personality types and interpersonal needs.
Korean Journal of Medical Education 2013;25(4):309-316
PURPOSE: Medical students' personality types and interpersonal needs must be considered. The purpose of this study was to examine the characteristics of personality types and interpersonal needs. METHODS: A total of 171 students in Konyang University College of Medicine were examined using the Myers-Briggs Type Indicator (MBTI) and Fundamental Interpersonal Relations Orientation-Behavior (FIRO-B). The data were analyzed by frequency analysis, t-test, and one-sample proportion test. RESULTS: The proportion of the 4 pairs of MBTI dimensions were Extroversion (E)-Introversion (I) (53.2% vs. 46.8%), Sensing (S)-Intuition (N) (63.2% vs. 36.8%), Thinking (T)-Feeling (F) (59.7% vs. 40.4%), and Judging (J)-Perceiving (P) (56.1% vs. 43.9%). The predominant personality types were ISTJ (16.4%), ESTJ (14.0%), and ESFJ (10.5%). The level of interpersonal needs were medium rage that was inclusion (mean=8.1), control (mean=8.8), affection (mean=8.1), expressed behavior (mean=12.1), wanted behavior (mean=12.9), and overall interpersonal needs (mean=25.0). Of the basic social needs, males and females differed significantly with regard to control needs (p=0.028). CONCLUSION: Educational programs that take into account personality types and characteristics of interpersonal needs are crucial in providing effective medical education. Our results suggest that the characteristics of personality types and interpersonal needs should be considered in developing an interpersonal relations improvement program for medical students.

9.Review on the administration and effectiveness of team-based learning in medical education.
Korean Journal of Medical Education 2013;25(4):271-277
Team-based learning (TBL) is an active learning approach. In recent years, medical educators have been increasingly using TBL in their classes. We reviewed the concepts of TBL and discuss examples of international cases. Two types of TBL are administered: classic TBL and adapted TBL. Combining TBL and problem-based learning (PBL) might be a useful strategy for medical schools. TBL is an attainable and efficient educational approach in preparing large classes with regard to PBL. TBL improves student performance, team communication skills, leadership skills, problem solving skills, and cognitive conceptual structures and increases student engagement and satisfaction. This study suggests recommendations for administering TBL effectively in medical education.

10.Operation of a school adaptation program considering the interpersonal needs of medical freshmen.
Korean Journal of Medical Education 2014;26(4):283-289
PURPOSE: We examined two overarching topics: What are the Fundamental Interpersonal Relations Orientation-Behavior (FIRO-B), Perceived Stress Scale (PSS), and Self-rating Depression Scale (SDS) scores in medical students? Do their interpersonal needs correlate with stress and depression? METHODS: FIRO-B, PSS-10, and SDS were administered to 82 freshmen in College of Medicine, The Catholic University of Korea in 2014. The data were analyzed by descriptive statistics, frequency, two-way analysis of variance, independent t-test, and Pearson correlation analysis using SPSS version 21.0 (IBM Corp.). RESULTS: The level of interpersonal needs was medium range (mean, 24.52). The mean perceived stress score was 18.6. Also, 59.8% and 40.2% of students had normal range (<20) and high stress (> or =20). The mean score for depression was 36.3. Further, 97.6% and 2.4% of students had normal range (< or =49) and mild depression (< or =59). Wanted behavior correlated with stress (r=0.056) and depression (r=0.021). Expressed behavior correlated negatively with stress (r=-0.206) and depression (r=-0.301). CONCLUSION: The interpersonal needs of medical freshmen are related to stress and depression. These results can be used effectively in school adaptation programs for medical students to improve their quality of life.
