Abstract
Background: Vascular tumors range from benign hemangiomas to lesions that are locally aggressive but infrequently metastasize, to relatively rare, highly malignant angiosarcoma. Objectives: The objective of this study is to determine the relative frequency and histologic pattern of these tumors in this locality and discover if any, differences in frequency and histopathological pattern from other centers. Materials and Methods: This was a 10-year retrospective study of all cases of vascular tumors diagnosed in the Department of Pathology, in a Teaching Hospital. Results: A total of 305 cases of vascular tumors representing 16% of soft tissue tumors were analyzed. The benign cases constituted 68% and the remaining were malignant. Lobular capillary hemangioma (40%) was the predominant benign histologic subtype recorded while Kaposi sarcoma constitute the most frequent malignant entity (21.6%). Head and neck was the most common site of affectation. Conclusion: Hemangiomas and Kaposi sarcoma was the most common benign and malignant vascular tumors recorded in this locality, respectively.
