ovarian endometriosis (endometrioma of the ovary)
Ovarian endometriosis. Note the hemosiderin-laden macrophages. IHC: CD10 highlights the endometrial stroma.
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.
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.
