title: [Intravascular malignant lymphoma (malignant angioendotheliomatosis). Apropos of a case with histologic, immunohistochemical and ultrastructural studies].
abstract: We report a new case of intravascular malignant lymphoma that arose in an 81-year-old woman. The most prominent symptoms were impressive dermatologic anomalies including painful, diffuse edema over which arborescent telengiectasic lesions could be seen. This clinical picture was associated with the presence, in deep skin biopsy specimens, of mononucleate tumor cells located within the lumen of dermal vessels. Complementary immunohistochemical and ultrastructural studies confirmed that the intravascular tumor growth was lymphomatous in nature. Clinical manifestations of this disease are recalled, and histopathologic features as well as the characteristic location of this malignant lymphoma are analyzed and discussed. Thus, we agree with Félix [3] and Witschi [6] that the cords of cells that will give rise to the follicular cells surrounding the ovocytes originate only from the coelomic epithelium; the primary mesenchyma forms the cortical stroma, and this embryonic type tissue, characterized by enourmous physiologic plasticity, differentiates into endocrine tissue to form the inner theca. the mesonephros plays no part whatsoever in the formation of the ovary.
