D efinition —A morphologic spectrum of tumors arising in endometriosis and displaying a müllerian (rather than intestinal) phenotype. Clinical Features Epidemiology Rare, reports limited to small series. Associated with borderline neoplasia usually serous or mucinous. Most present in the fourth…
D efinition — Noninvasive epithelial and stromal tumors with an atypical endometrioid epithelial component. Clinical Features Epidemiology Uncommon but not exceedingly rare; less than 200 reported cases but most pathologists will encounter at some point in their practice. Similar to…
D efinition — A benign epithelial and stromal tumor with an endometrioid epithelial component. Clinical Features Epidemiology Rare; these lesions represent less than 1% of all benign ovarian tumors. Most common in postmenopausal patients or women in their late reproductive…
D efinition — An adenocarcinoma typically derived from endometriosis and displaying well to moderate differentiation. Clinical Features Epidemiology Approximately 40% of low-stage tumors are associated with endometriosis. Those with endometriosis tend to be younger than those without. Approximately 5% associated…
D efinition — Marked intramucosal atypia in a borderline mucinous tumor of the ovary. Clinical Features Epidemiology The second most common epithelial tumor of the ovary and 12% to 15% of ovarian tumors. Approximately 10% of mucinous tumors are borderline.…
D efinition — An atypical proliferative mucinous tumor with intestinal differentiation, without stromal invasion or intraepithelial carcinoma. Clinical Features Epidemiology The second most common epithelial tumor of the ovary and 12% to 15% of ovarian tumors. Approximately 10% of mucinous…
D efinition — Mucinous tumors containing nodular foci in the cyst wall of altered mesenchymal and/or epithelial differentiation. Clinical Features Epidemiology Extremely uncommon; tendency toward women in the fifth and sixth decades. Associated with both borderline and malignant mucinous tumors.…
D efinition — A malignant mucinous tumor arising in the ovarian cortex. Clinical Features Epidemiology The least common of the major malignant epithelial tumors, accounting for about 2.4% of all primary malignant epithelial tumors of the ovary. Average age in…
D efinition — Low-grade serous tumor implants with high risk of a malignant or adverse outcome. Clinical Features Epidemiology Predominates in the fourth to sixth decades of life, but can be seen at virtually any age. Classically associated with borderline…
D efinition — An invasive low-grade serous carcinoma. Clinical Features Epidemiology The less common serous carcinoma. Predominates in the fourth to sixth decades of life, but can be seen at virtually any age. Can arise in a serous borderline tumor…
