The pathology of head and neck tumors: vasoformative tumors, part 9B. 1981

J G Batsakis, and D H Rice

There are three principal malignant vasoformative tumors that can be found in the head and neck--hemangiopericytoma, angiosarcoma, and Kaposi's sarcoma. All are uncommon and provide challenges for the pathologist and the therapist both. The histogenesis of each tumor is different. Kaposi's sarcoma has many features which suggest that it is an altered immune-response disease. Angiosarcoma is a malignancy of endothelium. Hemangiopericytoma is a tumor whose cell of origin is considered to be the perithelial pericyte. The general prognosis for patients with Kaposi's sarcoma is good. The biologic course of a hemangiopericytoma is variable and unpredictable, but there appears to be a site dependency. Angiosarcomas, particularly high grade lesions, are resistant to therapy.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011248	Pregnancy Complications	Conditions or pathological processes associated with pregnancy. They can occur during or after pregnancy, and range from minor discomforts to serious diseases that require medical interventions. They include diseases in pregnant females, and pregnancies in females with diseases.

D005918	Glomus Tumor	A blue-red, extremely painful vascular neoplasm involving a glomeriform arteriovenous anastomosis (glomus body), which may be found anywhere in the skin, most often in the distal portion of the fingers and toes, especially beneath the nail. It is composed of specialized pericytes (sometimes termed glomus cells), usually in single encapsulated nodular masses which may be several millimeters in diameter (From Stedman, 27th ed). CHEMODECTOMA, a tumor of NEURAL CREST origin, is also sometimes called a glomus tumor.	Glomangioma,Glomangiomas,Glomus Tumors,Tumor, Glomus,Tumors, Glomus
D006099	Granuloma	A relatively small nodular inflammatory lesion containing grouped mononuclear phagocytes, caused by infectious and noninfectious agents.	Granulomas
D006258	Head and Neck Neoplasms	Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck.

D006391	Hemangioma	A vascular anomaly due to proliferation of BLOOD VESSELS that forms a tumor-like mass. The common types involve CAPILLARIES and VEINS. It can occur anywhere in the body but is most frequently noticed in the SKIN and SUBCUTANEOUS TISSUE.

D006393	Hemangiopericytoma	A tumor composed of spindle cells with a rich vascular network, which apparently arises from pericytes, cells of smooth muscle origin that lie around small vessels. Benign and malignant hemangiopericytomas exist, and the rarity of these lesions has led to considerable confusion in distinguishing between benign and malignant variants.
