Angiomatosis with luminal cryoprotein deposition.

摘要: Background: Angioendotheliomatosis has recently been separated into two types. Malignant angioendotheliomatosis is a lymphoma in which the neoplastic cells accumulate vascular lumens. Reactive proliferation of capillaries that less well characterized. Objective: Our purpose was to describe clinical and histopathologic features three cases reactive angiomatosis patients with cryoproteinemia. Methods: Clinical histologic data were correlated. Immunoperoxidase staining electron microscopy used evaluation. Results: All showed tufts luminal deposits apoproteins. Immunohistochemical studies cellularity primarily caused by pericytes. Conclusion: Cryoproteinemia can cause simulates neoplasm.
