  • Benign Hemangiomas
    TUMORS OF BLOOD VESSELS CHARLES F. GESCHICKTER, M.D. (From tke Surgical Palkological Laboratory, Department of Surgery, Johns Hopkins Hospital and University) AND LOUISA E. KEASBEY, M.D. (Lancaster Gcaeral Hospital, Lancuster, Pennsylvania) Tumors of the blood vessels are perhaps as common as any form of neoplasm occurring in the human body. The greatest number of these lesions are benign angiomas of the body surfaces, small elevated red areas which remain without symptoms throughout life and are not subjected to treatment. Larger tumors of this type which undergb active growth after birth or which are situated about the face or oral cavity, where they constitute cosmetic defects, are more often the object of surgical removal. The majority of the vascular tumors clinically or pathologically studied fall into this latter group. Benign angiomas of similar pathologic nature occur in all of the internal viscera but are most common in the liver, where they are disclosed usually at autopsy. Angiomas of the bone, muscle, and the central nervous system are of less common occurrence, but, because of the symptoms produced, a higher percentage are available for study. Malignant lesions of the blood vessels are far more rare than was formerly supposed. An occasional angioma may metastasize following trauma or after repeated recurrences, but less than 1per cent of benign angiomas subjected to treatment fall into this group. I Primarily ma- lignant tumors of the vascular system-angiosarcomas-are equally rare. The pathological criteria for these growths have never been ade- quately established, and there is no general agreement as to this par- ticular form of tumor.

  • Kaposiform Hemangioendothelioma: Current Knowledge and Future Perspectives Yi Ji1*† , Siyuan Chen2*†, Kaiying Yang1, Chunchao Xia3 and Li Li4
    Ji et al. Orphanet Journal of Rare Diseases (2020) 15:39 https://doi.org/10.1186/s13023-020-1320-1 REVIEW Open Access Kaposiform hemangioendothelioma: current knowledge and future perspectives Yi Ji1*† , Siyuan Chen2*†, Kaiying Yang1, Chunchao Xia3 and Li Li4 Abstract Kaposiform hemangioendothelioma (KHE) is a rare vascular neoplasm with high morbidity and mortality. The initiating mechanism during the pathogenesis of KHE has yet to be discovered. The main pathological features of KHE are abnormal angiogenesis and lymphangiogenesis. KHEs are clinically heterogeneous and may develop into a life- threatening thrombocytopenia and consumptive coagulopathy, known as the Kasabach-Merritt phenomenon (KMP). The heterogeneity and the highly frequent occurrence of disease-related comorbidities make the management of KHE challenging. Currently, there are no medications approved by the FDA for the treatment of KHE. Multiple treatment regimens have been used with varying success, and new clinical trials are in progress. In severe patients, multiple agents with variable adjuvant therapies are given in sequence or in combination. Recent studies have demonstrated a satisfactory efficacy of sirolimus, an inhibitor of mammalian target of rapamycin, in the treatment of KHE. Novel targeted treatments based on a better understanding of the pathogenesis of KHE are needed to maximize patient outcomes and quality of life. This review summarizes the epidemiology, etiology, pathophysiology, clinical features, diagnosis and treatments of KHE. Recent new concepts and future perspectives for KHE will also be discussed.

A capillary angioma of the lips: An extremely rare situation in the oral cavity. Int. J. Odontostomat., 14(3):354-357, 2020. ABSTRACT: Hemangiomas are tumors identified by rapid endothelial cell proliferation in early infancy, followed mostly by involution over the time. However, 10-12 % of true hemangiomas don’t involute and require surgical treatment. Hemangiomas are classified on the basis of their histological appearance as capillary, mixed and cavernous. We report a case of capillary angioma in a 13-year old boy who presented with a budding into the lower lip. The lesion was excised and histopathological report confirmed the diagnosis. KEY WORDS: capillary angioma, lips. INTRODUCTION Oral cavity hemangiomas are not commonly most common type, it occurs as a small localized lesion encountered by general dentists.
