What symptom is angiosarcoma?
summary
Hemangiopericytoma is a rare soft tissue tumor derived from peripheral cells of capillary wall. Most of them are single occurrence. The most common sites are lower limbs, retroperitoneum and pelvic cavity. It can also occur in head and neck, trunk, upper limb soft tissue, viscera and nervous system. The diagnosis of this disease mainly depends on histopathological examination. Limited by the current medical level, the etiology of the disease is unknown, but it can be considered to be related to trauma, long-term use of corticosteroids, pregnancy and hypertension.
What symptom is angiosarcoma?
Hemangiopericytoma can be divided into three types: benign, borderline and malignant. The benign type has no metastasis and is obviously vascular type. There are more tumor cells in borderline type than benign type, and the vascular cavity is compressed and the contour is unclear. The degree of intercellular transformation of malignant tumors varies greatly, and the number of mitosis varies.
The skin of the lesion was red with large sclerotic plaques or nodules. Generally speaking, small and superficial tumors confined to skin and subcutaneous tissue have a better prognosis, while large and deep tumors have a poorer prognosis. This disease has malignant potential and is easy to recur and metastasize. The common sites of metastasis are bone, lung and liver.
The main symptoms were compression. The common lesions were skin, subcutaneous tissue, fascia and muscle of limbs. The clinical manifestations are similar to lipoma, which can spread downward and invade deep tissues. In addition to subcutaneous tissues and muscles, it can also invade epidural space, paraspinal space and pelvic retroperitoneal space.
matters needing attention
The diagnosis of this disease mainly depends on histopathological examination. It is easy to be misdiagnosed as hemangioma in extremities and glioma and meningioma in intracranial. Treatment: radical resection is the first choice, long-term follow-up is needed after operation, and preoperative radiotherapy can reduce the tumor volume. The effect of postoperative radiotherapy and adjuvant chemotherapy is not exact.
