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.

To determine the perinatal mortality and morbidity of fetuses with absent end-diastolic velocities (AEDV) of the umbilical artery in severe pre-eclampsia and eclampsia, the outcome of 5 fetuses with AEDV was compared with that of 35 fetuses with positive end-diastolic velocities (PEDV). The study population comprised 38 cases of severe pre-eclampsia and 2 cases of eclampsia with structurally normal singletons, who had had umbilical artery Doppler velocimetry weekly from admission to delivery. The Doppler velocimetry result was not used for the clinical management. Perinatal death and neonatal morbidity from both groups were further examined in gestational age category to control the influence of preterm births. The incidence of AEDV of the umbilical artery Doppler velocimetry in severe pre-eclampsia and eclampsia was 12.5% (5/40). The AEDV group had a significantly higher incidence than the PEDV group in terms of ceasarean section due to fetal distress (60% : 17%), Apgar score < 7 at 5 minutes (60% : 14%), perinatal death (25% : 0%) and assisted mechanical ventilation (67% : 9%) both at 32-36 weeks. Time intervals from the detection of AEDV to delivery of live neonates varied from the day to 15 days. In conclusion, AEDV in the umbilical artery might be of clinical value in routine surveillance of pregnancies complicated by severe pre-eclampsia and eclampsia, and predict hypoxic fetal condition which needs operative interventions before or during labor and mechanical ventilation after birth.

In spite of numerous clinical and patho-anatomical studies made in the past, there are still different opinions concerning the machanism of low back pain. We have focused attention on the posterior structures as an alternative source of low back pain with leg radiation, so we have studied and analyzed the effect of the injection of mixture methylprednisolone acetate suspension (20-40 mg) and local anesthetic (1% procaine, 1cc) into the posterior facet joint. In this paper, the records of 41 in-patients who have chiefly compalned of low back pain wlth leg radiation and have been treated at the Departmnt of Orthopedics, Han Yang University Hospital from May, 1979 to April, 1980 were studied. The following results are recognized by observing and analyzing their chief complalnts, physical examination, x-ray findings, the effect of facet block and the follow-up studies after facet block. 1. Low back pain with sciatica was 1.9 times more common in female than male, and frequently occured In 4th to 6th decades (75.7%). 2. The abnormal findings of plain x-rays were osteophyte (35.6%), marginal sclerosis (27.1%), narrowing of disc spce (18.6%), lumbarization (11.9%), spina bifida (3.4%), and tropism (3.4%). 3. The most frequent site of abnormal posterior facet joints was at the level between 4th and 5th lumbar vertebra (42.9%), and all were on lower lumber region. 4. The range of lumbar motion was decreased in the cases of abnormal posterior facet jolnt or degenerative changes, and it was especially more decreased in the combined cases. 5. The effect of facet block was as follows; In initial assessment, 29 of 41 cases (70.7%) showed complete rellef and one month later, 16 of 29 cases (55.2%) showed continuous rolief, 4 of 18 cases (22.2%) which were followed for 3 more months showed complete relief. 6. The effect of facet block according to pain character was as follows: 20 of 26 cases (76.9%) of numbness, 5 of 6 cases (83.3%) of dull pain and 4 of 8 cases (50.0%) of radlating pain were completely relleved and a case of burning pain was partially relleved.

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.
