Retroperitoneal liposarcoma is an infrequent, locally aggressive malignancy. We report two cases of huge retroperitoneal liposarcomas. The presence of a palpable abdominal mass was a common symptom of the two patients. Preoperative imaging study showed huge retroperitoneal tumors. Both patients underwent complete surgical resections, and a negative(More)
BACKGROUND Prostate cancer (PCa) is the second most frequently diagnosed cancer in male. In South Korea, PCa incidence has increased significantly, while its mortality rate has decreased steadily. To optimize the distribution of public medical resources, it is essential to analyze the contemporary epidemiology of PCa. METHODS National population data from(More)
Epidermal growth factor receptor (EGFR) is an important mediator of tumor cell survival and proliferation. The detection of EGFR mutations can predict prognoses and indicate when treatment with EGFR tyrosine kinase inhibitors should be used. As such, the development of highly sensitive methods for detecting EGFR mutations is important. Targeted(More)
PURPOSE We aimed to compare the cystatin C-based estimated glomerular filtration rate (eGFR) and the serum creatinine-based eGFR and to investigate the clinical roles of the cystatin C-based eGFR in assessing the follow-up renal function of kidney donors. MATERIALS AND METHODS We enrolled 121 healthy kidney donors who underwent live donor nephrectomy(More)
Massive weight loss results in skin excess, leading to an unsatisfying body contour. Various thigh lift procedures can correct flabby skin in the lower leg. We present a lower body contouring technique with a report on two patients. The procedure is determined by the body contour of the patient. As the skin excess in the thigh area tended to appear mostly(More)
Replantation of zone I finger injuries remains a challenge, particularly if the fingertip was previously scarred or atrophied, which makes it difficult to secure a suitable vein at the amputation site. In cases of artery-only anastomosis, we propose using a mechanical leech technique to maintain sufficient venous outflow until the internal circulation(More)
PURPOSE Blowout fracture characterized by concurrent floor and medial wall fractures is a rare entity. We compared surgical outcomes between a single approach and a double approach in patients with orbital fracture by measuring the postoperative orbital volume. METHODS We confirmed that 21 (8.5%) of a total of 246 patients with orbital fractures had(More)
Tumor growth-generated mechanical compression may increase or decrease expression of microRNAs, leading to tumor progression. However, little is known about whether mechanical compression induces aberrant expression of microRNAs in cancer and stromal cells. To investigate the relationship between compression and microRNA expression, microRNA array analysis(More)
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Dermoid cyst is a type of choristoma that generally originates from a bony structure due to abnormal ectodermal sequestration during the course of development. Dermoid cysts can appear in any part of body but 7 percent(More)
PURPOSE To identify size criteria for complex cystic renal masses that can distinguish renal cell carcinoma from benign cysts supplementing the Bosniak classification. MATERIALS AND METHODS We reviewed the records of 97 patients who underwent surgery for complex cystic renal masses from January 2001 to April 2010. The pathological results were compared(More)
