The involvement of @entity3506 by @entity5 after the diagnosis of an @entity43 of low malignant potential is extremely rare. In this study we present the clinicopathologic features of 12 such cases seen at our institution during a period of 19 years (1980-1999). The @entity1 ' age ranged from 19 to 50 years (mean 33 years). By FIGO staging the original @entity43 were distributed as follows: stage I, 4; stage II, 2; stage III, 5; unknown stage, 1. All @entity1 were treated surgically. Ten @entity1 also received adjuvant therapy (radiotherapy, 2; chemotherapy and radiotherapy, 4; chemotherapy, 3; intraperitoneal 32P, 1). The interval between the diagnosis of the @entity43 and the subsequent @entity5 involving an extra-abdominal/extra-pelvic site ranged from 4 to 240 months (mean 124 months). Sites of extra-abdominal/extra-pelvic involvement and the number of cases were as follows: left neck lymph nodes (LNs), 4; left and right neck LNs, 1; pleura, 2; lung, 1; mediastinum, 1; chest wall, 1; axillary and chest LNs, 1; and vertebral body, 1. Eight @entity1 were treated with chemotherapy, 1 with radiotherapy, 2 with chemotherapy and radiotherapy, and 1 with surgery alone. Follow-up ranging from 5 months to 18 years was available in 11 @entity1 . Six @entity1 died of disease and 5 @entity1 were alive with no evidence of disease. In this small series of cases, no definitive clinical or pathologic feature related to the occurrence of @entity530 was found. Based on the LN involvement and the @entity14708 seen in some cases, these @entity5 might develop from circulating @entity5 serous cells or from areas of @entity14708 involving @entity3506 .
