Well differentiated osteosarcomas are variants of osteosarcoma composed mainly of fibrous and osseous tissue with minimal cystologic atypia. This tumor may be misinterpretated as a benign lesion if the radiologic and clinical features are not taken into account. We report a typical case of intraosseous well differentiated osteosarcoma occuring in the left distal femur of a 58-year-old woman. Radiologically, it appered as an ill-defined lesion with a mixture of sclerotic and osteolytic ares. But there was a lack of highly destructive appearance of conventional osteosarcoma. Grossly, the mass occupied a metaphysis of the distal femur with extension into the diaphysis and epiphysis. Multifocal cortical destruction and sclerosis were also associated. Histologically, the mass showed typical features of intraosseous well differentiated osteosarcoma. There were various patterns of osteoid deposits and bone formation mimicking those of fibrous dysplasia, nonossifying fibroma or parosteal osteosarcoma.

Malignant rhabdoid tumor (MRT) is a rare and highly aggressive neoplasm of infancy and childhood. Although it was originally described and most frequently reported in the kidney, it may occur in various extra-renal sites such as the liver, thymus, and soft tissue. In the last decade primary central nervous system (CNS) MRTs have been reported in both the supra- and infratentorial compartments. Patients with CNS MRT were generally below the age of two and reports in adults are extremely rare. This is a case of primary cerebellar MRT in a 24-year-old woman, who had presented with intermittent headache, vocal cord palsy, and cerebellar dysfunctions such as abnormal finger to nose test and tandem gait. By magnetic resonance imaging scan, a well-enhancing solid mass was demonstrated at the posterior fossa filling the 4th ventricle, which extended into the medulla and cervical cord via the foramen of Magendie. Histologically, the monotonous polygonal tumor cells were arranged in diffuse sheet with occasional hemorrhagic necrosis. The nuclei were vesicular and eccentrically located due to eosinophilic, PAS-positive, intracytoplasmic inclusions with prominent nucleoli. They were diffusely or focally immunoreactive for vimentin, neurofilament, cytokeratin, GFAP, synaptophysin, and smooth muscle actin, while epithelial membrane antigen and desmin were negative. Ultrastructurally, the polyhedral tumor cells were densely packed with primitive intercellular junctions. Scanty fibrillar intermediate filaments were intermingled with cellular organelles. Postoperatively, craniospinal irradiation and systemic chemotherapy have been done and she has been free of tumor recurrence during the 13 months' follow-up periods.

OBJECTIVES: Breast cancer has been the most prevalent female cancer in South Korea since 2001. Early detection of this disease is the most effective strategy for reducing mortality. The objective of this study was to identify factors which could predict advanced stage at diagnosis of breast cancer. METHODS: Participants who were initially diagnosed with breast cancer and referred to the Stress Clinic of the Breast Cancer Center at Kyungpook National University Hospital were included. Through a semi-structured interview, the authors investigated psychosocial variables such as the extent of marital and family functioning and emotional-economic family burden as well as sociodemographic and health behavior-, health characteristic- and cancer-related variables. RESULTS: Data were collected from 219 participants. One hundred and twenty(54.8%) subjects were diagnosed with advanced-stage breast cancer. Variables that were significantly different between the advanced-stage and early-stage groups included : monthly breast self examination(p<0.000), annual mammographic screening(p< 0.000), mode of tumor detection(p<0.000), nature of the first symptoms(p<0.000), time to treatment after di-agnosis(p<0.000), overloaded economic and family burden(p=0.018), marital functioning(p<0.000) and family functioning(p<0.00). Logistic regression analysis indicated that irregular annual mammography screening(OR=7.431 ; 95% CI 2.407-22.944) or a lack of screening(OR=25.299 ; 95% CI 7.855-81.482) and a dysfunctional marital relationship(OR=4.772 ; 95% CI 2.244-10.145) were significantly associated with advanced stage at diagnosis of breast cancer. CONCLUSIONS: We reconfirmed screening behavior to be a risk factor for delayed diagnosis of breast cancer. Our findings also emphasized the importance of psychosocial factors such as marital functioning in early detection of breast cancer. Psychiatric consultation in the area of martial functioning could be beneficial for increasing early detection in breast cancer.

We report an autopsy case of a male fetus with Adams-Oliver syndrome. His mother was a healthy, 31-year-old woman and her family and past histories were unremarkable. Therapeutic termination was done at 28() weeks gestational age due to oligohydramnios detected by antenatal ultrasonography. Chromosomal study revealed normal karyotype. On autopsy, characteristic transverse terminal defect of four extremities was found. Both feet were short and broad. All toes were rudimentary with no nails and fingers were irregularly short. On infantogram, all toe-bones were stubby and rudimentary. The middle and terminal phalanges of 2nd, 3rd +ACY- 5th fingers and the terminal phalange of 4th finger on the right hand were absent. The middle and terminal phalanges of 2nd +ACY- 5th fingers and terminal phalange of 3rd finger were defected on the left hand. His abnormalities were consistent with features of Adams-Oliver syndrome, which has not been reported in Korea.

STUDY DESIGN: To study the correlation between the clinical outcomes and neovascularization and bFGF expression in the herniated disc tissues. OBJECTIVES: To study the difference of neovascularization and bFGF expression according to the types of disc herniation, and to study the correlation between the duration of radiculopathy, post-operative results and neovascularization and bFGF expression in the herniated disc tissues. SUMMARY OF LITERATURE REVIEW: Neovascularization has been found in herniated disc tissue. bFGF(basic Fibroblast Growth Factor) in the intervertebral disc has been implicated in the pathogenesis of injury and repair associated with granulation and neovascularization. There is no information on the relationship between clinical outcome and the neovascularization and bFGF expression in the herniated disc tissue. MATERIALS AND METHODS: Among 112 specimens, there are 48 cases in protrusion, 36 in extrusion and 28 in sequestration. Hematoxylin-eosin stain and immunochemical stain with CD 31 and bFGF were used. For the evaluation of post-operative results, Kirkaldy-Willis method was used. The results were analyzed with Chisquare test and t-test. RESULTS: Statistically there is no correlation between the types of disc herniation, duration of radiculopathy and post-operative outcomes and neovascularization and bFGF expression. CONCLUSIONS: The neovascularization and bFGF expression in herniated disc tissue are correlated with the injury of disc tissue. There are no correlation with the clinical outcomes and neovascularization and bFGF expression in herniated disc tissues.

Fine needle aspiration cytologic features of a case of insular carcinoma of the thyroid in a 23-year-old woman who presented a palpable neck mass is described. The aspirate showed cellular smear arranged in trabeculae, solid or loose clusters, and microfollicles in necrotic background. The tumor cells had uniform, small round, hyperchromatic nuclei. The chromatin was finely granular, and nuclear membrane was smooth. Nucleoli were not discernible. Nuclear pleomorphism was minimal. The cytoplasm was usually scanty, pale, poorly outlined, and almostly amphophilic. Sometimes paranuclear cytoplasmic vacuoles were noted. Final diagnosis was confirmed by total thyroidectomy as insular carcinoma.
