An oral hemangioma in a three-month-old child: clinical report.

چکیده
A rare presentation of an oral hemangioma in a 3month-old child is reported. The lesion was gray, began central in bone, and expanded rapidly into the oral cavity. The hemangioma is a tumor of mesenchymal origin. It is found occasionally in the oral cavity. The cellular hemangioma is one of a family of tumors characterized by the formation of vascular tubes of endothelial cells. The tumors are differentiated from one another by the predominant cell type found on histologic examination. Borrmann1 first used the term hemangioendothelioma in 1899. Later, Mallory2 used the term to describe a malignant vascular tumor. Stout 3 described the histologic features of hemangioma in 1944. A review of the literature reveals a variety of names which were used for tumors which exhibited vascular channels of endothelial origin. These include hemangioma, lymphangioma, angiosarcoma, hemangiosarcoma, angioendothelioma, and angioblastoma. 4-7 This varied terminology has led to a confusion in diagnosis and treatment of these tumors. Several authors have attempted to clarify this situation. ~-9 Shklar and Meyer 1° differentiate between an "extremely cellular benign hemangioma" and the hemangioendothelioma, which they prefer to refer to as an angiosarcoma. Others, however, feel that the term angiosarcoma is too nonspecific, referring simply to a sarcoma of blood vessels without reference to cellular origin. 9 They have advocated the term hemano gioendothelioma prefaced by a term identifying the clinical behavior of the tumor, for example, benign or malignant.~ In addition, a distinction has been made between the malignant hemangioendothelioma and the infantile form of hemangioendothelioma. This type is felt to be benign but can be fatal due to local extension from one or several of the tumors. 9 The malignant form also has been documented in infants and children. 7,1~ Shafer12 points out that the currently preferred term for the lesion previously designated juvenile hemangioendothelioma is cellular hemangioma. The authors subscribe to this latter view. The following is a clinical report of a rare presentation of an oral hemangioma which began central in bone and expanded rapidly into the oral cavity.
