PURPOSE: We analyzed the oncological outcome and prognostic factor of the chondrosarcoma arising from benign bone tumor due to malignant transformation. MATERIALS AND METHODS: From April 1986 to April 2009, 18 cases were considered eligible. We analyzed retrospectively the patient's characteristics and prognostic factors that affect to the local recurrence and distant metastasis. RESULTS: As classified by primary benign bone tumor, 4 cases were solitary osteochondroma, 11 cases were multiple osteochondromatosis and 3 cases were multiple enchondromatosis. The mean follow-up period was 85 months. The 5-year disease free survival rate of 18 patients was 85.9%. Their overall MSTS score was 25.2 (84%). There were local recurrence in 3 cases and no distant metastasis. We found that tumor location and surgical margin affected to the prognosis significantly. CONCLUSION: In secondary chondrosarcoma patients, the prognosis was good relatively and tumor location and surgical margin are important prognosis factor.

BACKGROUND: A number of factors can cause dark circles around the eyes including excessive pigmentation, thin and translucent lower eyelid skin overlying the orbicularis oculi muscle, and shadowing due to skin laxity and tear trough. Autologous fat graft is an effective method for the treatment of lower lid dark circles, but irregularities caused by leaving visible lumps of the fat can occur. Tonnard et al. suggested 'nanofat' grafting and introduced its characteristics and clinical applications. The authors used their nanofat grafting to correct lower eyelid dark circles. METHODS: Nanofat grafting was performed in 19 patients for dark lower eyelids. The grafts were injected into subdermal layer using blunt cannula. Microfat grafting with nasojugal fold was performed to all the patients. Among them, 18 patients received transconjunctival fat removal at the same time. RESULTS: All the patients showed much improvement from preoperative dark coloration. There were no visible lumps of fat, contour irregularities, or fat necrosis. Postoperative edema and ecchymosis were minimal. CONCLUSIONS: Nanofat grafting methods provide a good alternative for correcting dark circles by augmenting thin skin with lower complications. This simple, cost effective procedure is suitable for correction of dark circles and various skin rejuvenation purposes.

Clear cell sarcoma of kidney(CCSK) is a rare pediatric neoplasm characterized by a predominating component of clear cells, a predilection for metastases to bone, and a poor prognosis. The incidence of CCSK peaks during the 2nd year of life and adult cases are very rare. We report a case of CCSK encountered in the right kidney of a 39-year-old man. Grossly, it was a lobulated mass showing infiltrative margin, measured 7x5.5x5cm and had a homogeneous gray-tan color with a soft, fish-flesh consistency. Microscopically, about half of the tumor revealed the classic pattern of CCSK, having tumor cell cords or nests separated by the characteristic alveolar capillary networks. The tumor cells had clear pale cytoplasm, bland looking round nuclei and inconspicuous nucleoli. The other half showed the epithelioid-trabecular pattern forming pseudorosette or cord-like structures. Immunohistochemically, there was only a focal positive reaction to vimentin. Ultrastructurally, the tumor cells showed the primitive nephrogenic mesenchymal differentiation such as electron lucent cytoplasm, a small amount of organelles, scanty heterochromatin, inconspicuous nucleoli, and a lack of flocculant basal lamina material around the cytoplasmic membrane. We consider that this is a case of CCSK occuring in the oldest patient ever reported, confirmed by both immunohistochemistry and electron microscopy.

Heart failure unresponsive to bed rest, low sodium diet, digitalis, diuretics, vasodilators and cardiac inotropic agents is a difficult therapeutic problem. Although remission was achieved with such treatment, its duration was short and easily recurred. We present a report of severe refractory congestive heart failure in three patients successfully treated with Continuous Ambulatory Peritoneal Dialysis (CAPD). These patients were admitted to the hospital many times and treated by conventional methods but cannon maintain their condition for a long time. In all three patients, edema, pulmonary congestion, electrolyte abnormalities, decreased ejection fraction and fractional shortening of myocardioum were eliminated or improved by CAPD. All three patients improved from Class IV congestive heart to Class II, as defined by the New York Heart Association, and experienced a define improvement in their sense of well being We conclude CAPD as an effective and the useful treatment for servere congestive heart failure refractory to conventional medical treatments.

BACKGROUND: Studies of the ear-molding technique have emphasized the importance of initiating molding early to achieve the best results. In the present study, we describe the immediate effects and long-term outcomes of this technique, focusing on children who were older than the ideal age of treatment initiation. METHODS: Patients who visited our institution from July 2014 to November 2015 were included. Medical charts were reviewed to collect data on demographics, the duration of treatment, the types of deformities, and the manner of recognition of the deformity and referral to our institution. Parents were surveyed to assess the degree of improvement, the level of procedural discomfort at the end of treatment, any changes in the shape of the molded auricle, and overall satisfaction 12 months after their last follow-up visits. RESULTS: A review of 28 ears in 18 patients was conducted, including the following types of deformities: constricted ear (64.2%), Stahl ear (21.4%), prominent ear (7.1%), and cryptotia (7.1%). The average score for the degree of improvement, rated on a 5-point scale (1, very poor; 5, excellent), was 3.5 at the end of treatment, with a score of 2.6 for procedural discomfort (1, very mild; 5, very severe). After 12 months, the shapes of all ears were well maintained. The average overall satisfaction score was 3.6 (1, very dissatisfied; 5, very satisfied). CONCLUSIONS: We had reasonable outcomes in older patients. After 1 year of follow-up, these outcomes were well maintained. Patients past the ideal age at presentation can still be candidates for the molding technique.

PURPOSE: Although most peritrochanteric fractures in old age necessitates surgical treatment, daily life functions are still impaired after discharge. We assessed the types of peritrochanteric fracture, risk factors, and functional recovery in elderly patients who were over 65 years old. We also tried to determine factors for recovery to daily life. MATERIALS AND METHODS: From January 2006 to December 2007, among 61 patients who were over 65 years old with the possibility of 1 year follow-up, 50 patients were selected through interviews. After verifying age, sex, mode, types of fracture, and method, we analyzed daily living activities with a functional recovery index and estimated recovery of daily life functions after surgery, assuming a score increase if functional recovery was good. RESULTS: The mean age was 75.8 years, and females (31 patients, 62%) exceeded males. Slipping (27 patients, 54%) was the most common cause of fracture, and the intertrochanteric femur fracture was the most common fracture type (34, 68%). The average functional recovery index decreased 16.24% compared with the pre-operation value, having a tendency to decrease more in old age and female patients. Subtrochanteric femur fracture showed a 17.6% decrease in functional recovery index among the fracture types. CONCLUSION: In elderly patients over 65 years, the functional recovery index after peritrochanteric fracture decreased 16.24% on average compared with the preoperation state. The largest decrease was in basic life ability. The functional recovery index decreased more in old age, females, and subtrochanteric femur fracture, which indicates these factors influence functional recovery.

PURPOSE: We analyzed the oncologic outcome of the malignant transformed benign giant cell tumor of bone. MATERIALS AND METHODS: Between January 2000 and February 2012, 5 cases were referred with suspicious malignant transformation of benign giant cell tumor. No patients underwent radiation therapy. RESULTS: After referral, all patients received the wide excision of the tumor and its' pathologic diagnosis were osteosarcoma. As classified by the location of tumor lesion, 3 cases were located in the distal femur, 1 case was in the distal radius and 1 case was in the proximal femur. The average latent period between diagnosis of benign giant cell tumor and diagnosis of secondary malignant giant cell tumor was 49.2 months. (range, 24-126 months) The mean follow-up period was 21.6 months. There were subsequent local recurrence in 2 cases and 3 patients developed distant metastasis. All patients with lung metastasis were dead. CONCLUSION: Malignant transformation of benign giant cell tumor of bone can be occurred within 5 years. Therefore, when benign giant cell tumor suspicious malignant transformation, it is necessary to do more aggressive treatment.
