Hepatoid thymic carcinoma is an extremely rare subtype of primary thymus tumor resembling “pure” hepatoid adenocarcinomas with hepatocyte paraffin 1 (Hep-Par-1) expression. A 53-year-old man presented with voice change and a neck mass. Multiple masses involving the thyroid, cervical and mediastinal lymph nodes, and lung were detected on computed tomography. Papillary thyroid carcinoma was confirmed by biopsy, and the patient underwent neoadjuvant chemoradiation therapy. However, the anterior mediastinal mass was enlarged after the treatment whereas the multiple masses in the thyroid and neck decreased in size. Microscopically, polygonal tumor cells formed solid sheets or trabeculae resembling hepatocytes and infiltrated remnant thymus. The tumor cells showed immunopositivity for cytokeratin 7, cytokeratin 19, and Hep-Par-1 and negativity for α-fetoprotein. Possibilities of germ cell tumor, squamous cell carcinoma, and metastasis of thyroid papillary carcinoma were excluded by immunohistochemistry. This report on the new subtype of thymic carcinoma is the third in English literature thus far.

Background: Mobile applications are useful in the field of dermatology as diagnosis and treatment are based on visual inspection. However, in Korea, dermatology-related applications have not been developed effectively despite the high rate of mobile internet usage. In addition, there is no report on the current trends of dermatology-related mobile application. Objective: This study aimed to identify and categorize the available dermatology-related mobile application and compare the current trends in Korea with those in the US. Methods: Eight dermatologic terms were queried in two mobile platforms, Android and iOS. Applications were categorized by function based on their description. The number of reviews, rating, provider, target audience, and price of applications were recorded. Results: A total of 213 dermatology-related applications were identified. Approximately 10.8% of the applications were related to skin diseases, 23.5% were related to skin care, and 65.7% were others. Among the applications related to skin diseases, 4.2% were self-surveillance/diagnosis apps, 3.3% were disease guide and reference apps, and 1.4% were dermoscopy apps. No applications were related to educational aid and photography search. Among the applications related to skin care, 12.7% were self-surveillance/diagnosis apps used for general skin care, 3.8% were skin care apps, and 2.8% were cosmetics apps. Other categories included shopping (24.9%), advertisements (15.0%), and hospital searches (15.0%). Conclusion The development and use of dermatology mobile applications can contribute to the efficient delivery of accurate information to patients, educate patients, and further reduce the prevalence of skin diseases. Therefore, dermatologists should play a leading role in presenting the direction for dermatology-related mobile application development.

Apocrine hidrocystoma, also called apocrine cystadenoma, is a benign cystic tumor-like lesion that arises from the proliferation of apocrine glands. Clinically, it usually occurs singly as a unilocular or multilocular, dome-shaped translucent cyst. Histologically, it appears as unilocular or multilocular cysts composed of an inner layer of single or double layer of secretory columnar epithelium with decapitation secretion lying above an outer myoepithelial cell layer. Apocrine hidrocystomas mostly occur within the head and neck region and involvement of genitalia is extremely rare. This paper emphasizes the importance of considering the differential diagnosis of a genital cystic lesion. Herein, we report a case of apocrine hidrocystoma occurring in the penis and compare the clinicopathological characteristics of apocrine hidrocystoma in genitalia with the previous cases.

The hospital standardized mortality ratio (HSMR) is a widely used generic measure for assessing quality of hospital care in many countries. However, the validity of HSMR as a quality indicator is still controversial. We critically reviewed characteristics of HSMR and suggested how to use HSMR as a quality indicator in the Korean setting. The association between HSMR and other quality measures of hospital care is inconclusive. In addition current HSMR model has shortcomings in risk adjustment because of the lack of clinical data, accuracy of disease coding, coding variation among hospitals, end-of-life care issues, and so on. Therefore, HSMR should be used as an indicator for improvement, not for judgement such as public reporting and pay-for-performance. More efforts will be needed to tackle practical and methodological weaknesses of HSMR in the Korean setting.

BACKGROUND: This study aimed to understand and explore perception of healthy adults and chronically ill adults on health and health-related quality of life (HRQoL). METHODS: Data were collected by open questions using a focus group discussion for healthy adults (N=6) and in-depth interviews for chronically ill adults (N=6). Previously developed 34 HRQoL items also were offered and participants were asked to select the five most important HRQoL items among them. RESULTS: Findings were elicited along the following themes: health, HRQoL, health maintenance strategies, and elements affecting health. The definition on "being healthy" by healthy participants had a variety of standards and required several conditions to be fulfilled. Whereas chronically ill adults have more flexible perception about the coexistence of health and disease. Health dimensions were thought to affect each other, and physical and mental health dimension were selected as the most important items. As for the five most important HRQoL items, both group participants selected mental health dimension than physical or social health dimensions. Health maintenance strategies were similar in both groups except more healthcare service use in chronically ill adults. CONCLUSIONS: This study shows the difference of perception on health and HRQoL between health group and disease group in Korea. It can be used for developing the HRQoL assessment tool reflecting the perception of Korean people.

OBJECTIVE: Detection of intracranial multiple aneurysms, including mirror-image aneurysms, have recently been increasing with the development of diagnostic techniques. However, studies of mirror-image aneurysms have been rare in South Korea. Thus, we intend to report our hospital's experience with mirror-image aneurysms during the past 20 years along with a review of relevant literature. METHODS: We analyzed medical records and image data from patients with cerebral aneurysms who had been admitted to our institution from January 1988 to June 2007. We divided the patients into three groups and investigated the clinical patterns of mirror-image aneurysms (Group 1). We then compared them with patients exhibiting non-mirror multiple aneurysms (Group 2) and the patients with solitary aneurysms (Group 3). We also statistically analyzed the age, sex, smoking habits, medical histories, and prognoses of the patients. RESULTS: Mirror-image aneurysms were found in 62 (5.1%) of the 1,209 patients admitted for cerebral aneurysms over the past 20 years. Of the mirror-image aneurysms, 48% were located in the posterior communicating artery (PcoA), and 40% were in the middle cerebral artery (MCA). Ruptures of aneurysms occurred slightly more frequently on the right side and when the aneurysm was larger and its shape was more irregular. Women, particularly menopausal women aged 50 and older, were shown to be at higher risk. Smoking was also a risk factor. However, there were no significant differences in prognoses among the three groups. CONCLUSION: We should pay attention to the possibility of mirror-image or multiple aneurysms when diagnosing and treating menopausal women and smokers, particularly if the cerebral aneurysm is located in the MCA or PcoA.

PURPOSE: We wanted to evaluate the technical feasibility and safety of totally laparoscopic total gastrectomy (TLTG) for treating early gastric cancer. MATERIALS AND METHODS: The medical records of 11 consecutive patients who underwent TLTG after being diagnosed with early gastric cancer at Incheon St. Mary's Hospital, The Catholic University of Korea from February 2005 to September 2009 were retrospectively reviewed and their clinicopathologic characteristics and the surgical results were investigated. RESULTS: The mean operation time was 385.6+/-94.1 minutes, the mean time for creating an intracorporeal anastomosis was 97.5+/-60.0 minutes and the mean number of the harvested lymph nodes was 46.6+/-15.4. The mean number of days after operation until starting a liquid diet was the 6.15+/-7.6th postoperative day and the mean hospital stay after surgery was 14.2+/-11.9 days. There was no case of open conversion, but there were 2 cases of intraoperative complication and 3 cases of postoperative complication. There was one case of postoperative mortality. The patient suffered from thrombocytopenia of an unknown cause, which was refractory to platelet transfusion, on 4th postoperative day and the patient died of intraabdominal bleeding on the 6th postoperative day. CONCLUSION: TLTG was a technically feasible and relatively safe procedure. However, a long time for creating the intracoproeal anastomosis and a long operation time are still problems to be solved.
