Benign tumors of the Female Reproductive Tract

 

Pelvic mass

A  pelvic  mass  may  be  gynecologic  in  origin  or  it  may  arise  from  the

urinary tract or bowel.

The  gynecologic  causes  of  a  pelvic  mass  may  be  uterine,  adnexal,  or

more speci cally ovarian.

我們就這幾個年齡層分述如下：

Prepubertal Age Group - Di erential Diagnosis

 

< 5% of ovarian malignancies

Germ cell tumors make up 1/2 to 2/3

35%  of  all  ovarian  neoplasms  occurring  during  childhood  and

adolescence were malignant

< 9y/o, 80% malignant

< 5% of ovarian malignancies occur in children and adolescents.

Ovarian  tumors  account  for  approximately  1%  of  all  tumors  in  these

age groups.

Germ cell tumors make up 1/2 to 2/3 of ovarian neoplasms in < 20 y/o,

compared with 20% of these tumors in adults.

A  review  of  studies  conducted  from  1940  until  1975  concluded  that

35%  of  all  ovarian  neoplasms  occurring  during  childhood  and

adolescence were malignant.

In girls < 9 years of age, approximately 80% of the ovarian neoplasms

were malignant.
