Parosteal lipoma is a rare and generally asymptomatic benign tumor of mature adipose tissue that is located in direct apposition to the external surface of the bone. These tumors are occasionally associated with reactive changes in the underlying bone. The reactive bone formation is generally restricted to the base of the tumor, that is, near the periosteum. We recently experienced a case of parosteal lipoma in the proximal femur, which displayed exuberant bone and cartilage formation, and this led us to a misdiagnosis of chondroblastic osteosarcoma on the initial biopsy. We report here on this case with a special emphasis on making the differential diagnosis from osteosarcoma.

BACKGROUND: To describe factors affecting the prognosis after operation for recurrent intermittent exotropia (X[T]) in children. METHODS: Clinical records of 50 patients who underwent operation for recurrent X(T) by a single surgeon were reviewed. The age at diagnosis of X(T), and first and second operations, deviation angle at distance and near, surgical method, concurrent vertical strabismus, stereoacuity, and Worth's Four Dot (W4D) examination before reoperation were analyzed, along with the postoperative deviation angle. A successful surgical outcome was defined as orthophoria, esodeviation ≤ 5 prism diopters, or exodeviation ≤ 10 prism diopters at distance. RESULTS: Among the 50 recurrent exotropes who underwent surgery and were followed up for more than 1 year postoperatively, 13 showed recurrent exotropia and 1 showed consecutive esotropia. The mean age at reoperation was 8.49 ± 2.19 years, and the mean duration of postoperative follow-up was 27.78 ± 12.02 months. Good near fusion before reoperation was a significant factor in the success of surgery (P = 0.006). Smaller postoperative deviation angle measured immediately and 2 months after surgery were related to smaller final deviation angle (P = 0.027 and P = 0.022, respectively). CONCLUSION: Peripheral suppression lowers the success rate of operation for recurrent X(T) in children. Overcorrection rather than orthotropia should be the target of immediate postoperative deviation angle. Peripheral suppression status and immediate and 2-month postoperative deviation angle may be important clues for predicting the final result of operation for recurrent X(T).

Post-transplant lymphoproliferative disorder (PTLD) following solid organ transplantation is an important form of post-transplant malignancy. PTLD is typically associated with Epstein-Barr virus (EBV) and occurs in the setting of immunosuppression resulting in a deficiency of EBV-specific cytotoxic T lymphocytes. PTLD encompasses heterogeneous lymphoproliferative diseases, from polyclonal proliferation resembling infectious mononucleosis to aggressive monomorphic proliferation such as diffuse large B-cell lymphoma. Clinically, PTLD is usually manifested as lymph nodal mass or extranodal mass of solid organs such as liver, transplanted kidney, tonsil, bone marrow or spleen. The authors experienced very rare case of PTLD manifested as a single mass in a native kidney. According to a review of the literature, this is a rare case of PTLD which developed in a native kidney after kidney transplantation. Initially under the impression of renal cell carcinoma, unilateral nephrectomy of the native kidney had performed, and after confirmed as PTLD by histologic diagnosis the patient had treated with reduction of immunosuppressants and chemotheraphy for PTLD, and eventually has got in complete remission.

Gastric metastasis from breast cancer is rare and only six cases have been reported in Korea. Colon metastasis is more rare than gastric metastasis. We report a 63-year-old woman with gastric and colon metastases of invasive lobular carcinoma of breast. She was diagnosed as right breast cancer, received right modified radical mastectomy 10 years ago and has been treated with chemotherapy and hormone therapy. Investigating for melena and a small caliber of stool, we found gastric and colon metastases. The diagnosis of metastatic breast cancer was made through gross pathologic and immunohistochemistry staining. We report a case with gastric and colon metastases from breast cancer and a review of the associated six case reports in Korea.

A seventyone-year-old male presented with sudden epigastric pain followed by jaundice and intermittent right upper abdominal pain. He was diagnosed as hepatocellular carcinoma 7 years ago, and has been treated with transarterial chemoembolization, percuaneous ethanol injection and segmentectomy. On admission, the level of serum bilirubin, amylase and lipase were 8.7 mg/dL, 560 IU/L, and 13,297 IU/L, respectively. Stool occult blood test was positive. Abdominal computed tomography revealed newly-appeared intraductal soft tissue mass with ductal dilatation. Endoscopic retrograde cholangiography demonstrated filling defects in the common hepatic and distal common bile duct (CBD). Endoscopic sphincterotomy was performed and the clots in the distal CBD were removed. An intraductal stent was inserted at the common hepatic duct. The obstructive jaundice and pancreatitis were resolved. Our case suggests that intraductal hepatocellular carcinoma may induce hemobilia as a possible cause of acute pancreatitis.

Choledochocele is a kind of choledochal cyst and represents a prolapse or herniation of the intramural segment of the distal common bile duct into the duodenal lumen. It is rare congenital anomaly and, easlily overlooked due to non-specific clinical symptoms, signs, and non-characteristic radiologic features. The cause of choledochocele remains uncertain and it was suggested that thete are two distinct types in the pathogenesis of it, i.e., congenital and acquired. Recently, many cases of choledochocele were reported, which diagnosed by ERCP and safely treated with endoscopic unroofing and EST followed by continued observation as well as interval ERCP and/or endoscopic ultrasonography. We present here four cases of symptomaatic choledochoceles that had been managcd by end- oscopic therapy and continucd observation.

OBJECTIVES: To evaluate whether the day of delivery for women with regular menstrual history was predicted best from the last menstrual period (LMP), crown rump length (CRL) and or biparietal diameter (BPD). METHODS: All of 561 women had estimated the day of delivery by LMP, CRL in the first trimester (In case of 217 women, it was available) and BPD in the second trimester. The accuracy of each method in predicting the day of delivery was determined. Those who were delivered after the spontaneous onset of labor were included. Differences among these methods were evaluated with nonparametric tests. RESULTS: The percentage of women who delivered within 3 days of the estimated day of delivery was 254(45.3%) and 216(38.5%) of the women with pregnancies by BPD and LMP, respectively. And within 7days of the estimated day were 408(72.7%), 390(69.5%) of the women from BPD and the LMP. In the women, the BPD estimate was significantly better predictor within the 7days of the day of delivery than LMP estimate (p=0.027). Compared to LMP estimate, CRL and BPD estimates seemed to be advanced the day of delivery about 2.6 days in CRL, and 0.9 days in BPD (p=0.004, p=0.034). But we could not find any advantage of the CRL measurement in first trimester than single BPD measurement in the second trimester for the predictor of the day of delivery. CONCLUSIONS: When the difference between the methods in predicting the day of delivery was less than 7 days, the BPD measurement was better than the last menstrual period.

Sacroiliac (SI) joint pain can result from degeneration, infection, malignancy, and trauma. Patients with metastatic bone pain who do not respond to conventional treatment may need more aggressive neuroinvasive approaches. Recently, pulsed radiofrequency (PRF) neuromodulation has emerged as a promising treatment alternative for refractory cases of SI joint pain. Nevertheless, there is no report on the treatment of pain arising from SI joint metastases with PRF. We are reporting about a 63-year-old woman suffering from buttock pain due to breast cancer metastases in the SI joint. We treated this patient with PRF neuromodulation of the L4-S3 primary dorsal rami and lateral branches using a rotating curved needle technique. The patient tolerated the procedures well, without any complications. She experienced about 70% reduction in pain, and pain relief was sustained for 10 months. This result suggests that PRF neuromodulation is a safe, effective treatment for pain from SI joint metastases.

PURPOSE: To reveal the incidence and clinical manifestations of steroid-induced cataract, and to evaluate the visual outcome after cataract surgery in children. METHODS: We reviewed the charts of the pediatric patients who had been receiving oral prednisolone for at least one year and had visited the ophthalmologic clinic between January 1991 and December 2006, and enrolled the patients who had been diagnosed as having steroid-induced cataracts. We investigated the total dose and duration of medication and compared the visual acuity (VA) at the initial visit with that of the last follow-up. We also compared the pre- and post-operative best corrected visual acuity of the patients who had undergone cataract operation. RESULTS: Among the 1408 patients who had been treated with systemic steroids for over one year, lens opacities were found in 92 eyes (2.5%). The total duration and dose of medication were not significantly correlated with the VA (R2<0.1). The lens opacities were found bilaterally in 88 eyes (91.7%), and unilaterally in 4 eyes (8.3%). The posterior subcapsular opacities were the most frequent (84.8%). In 81 eyes who had not undergone surgery, there was no significant change of VA (p=1). The 11 eyes who had undergone cataract surgery showed significant increases in VA (p<0.01). CONCLUSIONS: The incidence of steroid-induced cataract in pediatric patients was 2.5%. The dose and duration of medication were not significantly correlated with the visual impairment. There was no significant change in VA during the follow-up. The surgical outcome of the cataract operation was favorable.
