ovarian neoplasm

Most ovarian neoplasms in children and adolescents are of germ cell origin.

In one series of 19 patients younger than 21 years with epithelial ovarian neoplasms, the average age at diagnosis was 19.7 years.

Surface epithelial-stromal tumors are a class of ovarian neoplasms that may be benign or malignant.

Serous tumours are part of the surface epithelial-stromal tumour group of ovarian neoplasms.

One rare but noteworthy condition associated with mucinous ovarian neoplasms is pseudomyxoma peritonei.

Ovarian fibromas represent 4% of all ovarian neoplasms.

Immunohistochemistry may help in diagnosing Krukenberg tumors from primary ovarian neoplasms but needs to be applied with discretion.

Laparoscopy may be an option if the surgeon is particularly skilled in removing ovarian neoplasms via laparoscopy intact.

They are part of the surface epithelial tumor group of ovarian neoplasms (10-20% of which are the endometrioid type).

Thecomas or theca cell tumors are benign ovarian neoplasms composed only of theca cells.

Borderline mucinous cystadenomas make up about 10% of mucinous ovarian neoplasms and are bilateral in 10% of cases.

Malignant mucinous cystadenoms are rare, and encompass 10% of mucinous ovarian tumors and 5-10% of primary malignant ovarian neoplasms overall.

Mucinous tumors (or mucinous tumours) are part of the surface epithelial-stromal tumor group of ovarian neoplasms, and account for approximately 36% of all ovarian tumors.
