ovarian endometriosis

Synopsis

 Endometriosis, or endometrioma, of the ovary may cause an adnexal mass in reproductive age females.
 Pigmented foci on an otherwise normal ovary or a large solitary hemor-rhagic cyst are the gross findings.

Microscopy

 Histologic findings include columnar-to-plump cuboidal epithelium with condensed sub-epithelial stroma, hemosiderin-laden macrophages, fibrosis, and inflammation.
 Rare cases may also contain smooth muscle.
 Patients with uterine anomalies may develop severe endometriosis.

Variants

 ovarian endometriotic cyst (ovarian "endometrioma")
