The terminology of hemangiomas has faced recommendations by the International Society for the Study of Vasular Anomalies to rename the lesions' as "venous malformations" to present consistent language for practitioners and patients. However, the term "vertebral hemangioma" remains dominant throughout the literature. [22] [23]
Depending on the grade of the sarcoma, it is treated with surgery, [8] chemotherapy, and/or radiotherapy.Though surgery is the current standard of care for hemangiopericytomas, metastasis and tumor recurrence occur in more than 30% of patients, in particular recurrence in the pelvis and retroperitoneum [3] and metastasis in bone and lungs.

Spinal cord compression is commonly found in patients with metastatic malignancy. [10] Back pain is a primary symptom of spinal cord compression in patients with known malignancy. [11] Back pain may prompt a bone scan to confirm or exclude spinal metastasis. Rapid identification and intervention of metastatic spinal cord compression is ...
The treatment for hemangioblastoma is surgical excision of the tumor. [5] Although usually straightforward to carry out, recurrence of the tumor or more tumors at a different site develop in approximately 20% of patients. [ 1 ]
Patients with a global deterioration of health status requiring discontinuation of treatment without objective evidence of disease progression at that time should be classified as having “symptomatic deterioration”. Every effort should be made to document the objective progression even after discontinuation of treatment.
[2]: 599 These tumors were reclassified by Dr. Weiss in 1996 as "spindle cell hemangioma", rather than hemangioendothelioma, due to the excellent prognosis observed in a group of 78 patients. [ 5 ] Retiform hemangioendothelioma (also known as a "Hobnail hemangioendothelioma" [ 3 ] ) is a low-grade angiosarcoma , first described in 1994 ...
A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma, known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life.
Cavernous hemangiomas are erroneously called the most common benign tumors of the liver. [14] Usually one malformation exists, but multiple lesions can occur in the left or right lobe of the liver in 40% of patients. [3] Their sizes can range from a few millimeters to 20 centimetres. Those over 5 cm are often referred to as giant hemangiomas. [3]
