  • Rhabdomyoma is the most common benign cardiac neoplasm in neonates. Most patients with rhabdomyoma experienced spontaneous regression. Yet some of them need surgical therapy because of hemodynamic problems of the heart such as arrhythmia, outflow tract obstruction and valvular dysfunction. We found multiple masses in both ventricles on the patient's fetal echocardiogram. Heart failure caused by severe left ventricular outflow tract obstruction quickly presented after birth. The mass interfering with the outflow tract was resected via the transaortic approach at the first day of birth. Postoperative echocardiography showed complete release of the outflow tract obstruction. He was discharged on the postoperative day 8. During the 3 years of follow up, we found that the sizes of the remnant masses had gradually decreased.

  • Purpose : Neuroblastoma is a malignant neoplasm which arises from primitive sympathetic neuroblasts, and occasionally can matured from a malignant neuroblastoma into a benign ganglioneuroma. It has the highest rate of spontaneous regression of any pediatric tumor. We performed a retrospective study of pathologic features after combination therapy in advanced neuroblastoma. Prognostic effects of the individual morphologic feature and prognostic groupings according to modified Shimada classification systems were analyzed. Methods : The treatment results for six patients with neuroblastoma seen at Keimyung University from Jan. 1991 to June 2000 were analyzed. Patients were treated with a combination of chemotherapy, radiation therapy, and surgery, and classified by two major prognostic criteria based on morphological features of neuroblastoma, such as modified Shimada classification and histologic grading. Results : Three cases were classified to a good histologic group; among them, two cases survived, but one case was lost in follow-up. There were three cases classified in a poor histologic group. All of these patients expired due to sepsis and hemorrhagic pancreatitis. Conclusion : Prognostic classification due to pathologic findings had significant value in evaluating the survival rate of neuroblastoma patients.
