Cytokeratin expression in epithelioid vascular neoplasms
Human Pathology, 1990Seven epithelioid and eight non-epithelioid vascular tumors were studied by the avidin-biotin-peroxidase method for the presence of endothelial- and epithelial-associated markers, using Ulex europaeus agglutinin-1 (UEA-1) lectin, and antibodies directed against factor VIII-related antigen, (FVIII-RA), vimentin, keratin, carcinoembryonic antigen, and ...

Vascular Lesions Presenting as Musculoskeletal Neoplasms
American Journal of Roentgenology, 2011The purpose of this article is to describe how to distinguish between vascular lesions and other soft-tissue tumors such as sarcomas on various imaging modalities.Careful attention to imaging characteristics, patient history, and presentation is essential to differentiate vascular lesions from sarcomas and other tumors.

Vascular Neoplasms and Malformations
2013This chapter will cover vascular anomalies according to the subcategories of vascular neoplasms (benign and malignant), vascular neoplasms of uncertain behavior, vascular malformations and vascular dilatations. Importantly vascular neoplasms are regarded as lesions, which undergo cellular proliferations, while vascular malformations are the result of ...

Vascular and Capsular Pseudoinvasion in Thyroid Neoplasms
International Journal of Surgical Pathology, 2009The diagnosis of follicular carcinoma of the thyroid requires the identification of capsular and/or vascular invasion, with the exception of distant metastases. However, several artifacts may mimic both vascular and capsular invasion. This article presents two cases of pseudo invasion in encapsulated follicular neoplasms.

c-myc and Cutaneous Vascular Neoplasms
The American Journal of Dermatopathology, 2013The c-myc proto-oncogene is involved in various cellular processes including cell growth, proliferation, and apoptosis. Overexpression and deregulated expression of the gene have been previously linked to several lineage-unrelated, aggressive, and poorly differentiated tumors.

[Vascular neoplasms of the mediastinum].
Khirurgiia, 1991During a period of 42 years the authors had 44 patients with various vascular neoplasms of the mediastinum--angiomas. Experience in the treatment of 6 of them is discussed in B. V. Petrovsky's monograph Surgery of the Mediastinum (1960). The other 38 cases were distributed as follows: hemangiomas 28 (14 mature and 14 immature) and lymphangiomas 10 (all

Associated Vascular Malformations and Neoplasms in Children
Pediatric Neurosurgery, 2008Primary CNS neoplasms can rarely be associated with abnormal vascularity which is more striking than usual hypervascularity or neovascularization. These lesions are sometimes reported as angiogliomas, angiomatous astrocytomas, or descriptively as two distinct pathological entities.

[Classification of vascular neoplasms].
Der Hautarzt; Zeitschrift fur Dermatologie, Venerologie, und verwandte Gebiete, 1979Neoplasms of blood and lymph vessels differ from angiectatic and angiokeratotic nevi by real proliferating growth. According to their features of growth and their wall structures, they are classified into three main groups: angiomas, glomangiomas and malignant vascular tumors. Within the angiomas on the one hand, capillary angiomas are classified into:
