Angiotropic large cell lymphoma of the prostate gland: an immunohistochemical study.
Malignant angioendotheliomatosis (MAE) is a rare disorder characterized by the intravascular proliferation of neoplastic mononuclear cells. Until recently, the cell of origin was uncertain; some investigators reported MAE to be lymphomatous in nature, while others claimed it to be of endothelial derivation. In the present unusual case, MAE was an incidental findings in the prostate of a patient with prostatic adenocarcinoma; it is shown to be a lymphoma of B-cell origin.
