Lymphangioma of the ovary: a case report and review of the literature

Abstract

Lymphangioma of the ovary is a very rare tumor which is usually silent and identified incidentally at operation or autopsy. We report on a 61-year-old woman with lymphangioma of the ovary and review the relevant literature. The microscopic examination of the left ovary revealed numerous vascular spaces of different dimensions of which the inner surfaces were lined with flattened endothelial cells with neither cellular atypia nor extraluminal or intraluminal proliferation. There was no evidence of haemorrhage or necrosis. The stroma was formed by fibrocollagenous tissue infiltrated by rare lymphocytes. The cells lining vascular spaces were immunoreactive for CD31 by immunohistochemical staining.
