Abstract:
Objective To explore clinicopathological features and prognosis of juvenile granulosa cell tumor (JGCT).Methods Patients were divided into JGCT group (n=10) and the adult granulosa cell tumor (AGCT) group (n=10).The tumor samples were examined by HE and immunohistochemical methods.Results Age of JGCT group ranged from 7-31 years (average 20.5 years);90% occurred before 30 years old.Diameter of the tumors ranged from 5.5 cm to 15.0 cm,average 9.8 cm.Characteristic features included nodular arrangement,irregular formation of follicles containing muein and luteinization, atypical hyperplasia of ceils and high mitotic activity.Nuclei grooved and Call-Exner bodies were absent or rare.Survival rate was 90% in 5 years.Age of AGCT group ranged from 14-74 years (average 45.1 years);AGCT occurred mostly in over 40 years old.Atypical hyperplasia of cell,mitotic activity and luteinization were absent or rare.Nuclei grooved and eall-Exner bodies were common.Survival rate was 100% in 5 years.Immunohistochemical staining were positive for p53 at 70%,PCNA at 90% in 10 cases of JGCT and p53 at 10%,PCNA at 20% in 10 cases of AGCT(P
