Although fibrous smoothie maker sarcoma (fibrosarcoma) previously thought to be one of the most common sarcoma, smoothie maker but the descriptions of the characteristics of benign fibrous lesions (fibromatoses) had earlier smoothie maker led to the incidence smoothie maker of fibrosarcoma lower than reported. The result is now lagging behind fibrosarcoma in fibrous tissue malignant tumor (malignant fibrous histiocytoma) in frequency [74]. Although can occur in any age, is more common in fibrosarcoma Thursday next decade smoothie maker eighth, having a smaller peak at a nascent stage and small children. There is an increased incidence in men and the place burns or radiation, but prone than other sarcomas, such as malignant smoothie maker fibrous tumor tissue.
Fibrosarcoma with typical manifestation is a slow-growing mass, no pain. It may be shallow from subcutaneous or deep soft tissues of the neck. These tumors tend to be shallow when detecting smaller tumors in deep [74]. Histological morphology changes, with low tumor grade is the next solid tumors express high levels of bleeding and necrosis. The distinction lesions with low grade invasive fibromatosis can be difficult, but the only new metastatic fibrosarcoma.
In the picture, the signs of nonspecific fibrosarcoma. The low grade lesions is heterogeneous on CT and hypointense smoothie maker on T1 and T2-weighted images. The phenomenon of drug absorption as well clearly u mild to moderate but well defined by MRI after contrast injection on CT [75]. Distinguish benign lesions invasive fibrosis can be difficult because they are quite similar. However, the presence of necrosis caused inclined diagnosed fibrosarcoma higher level. Diagnostic imaging, especially MRI, plays a key role to determine the spread of such tumors. smoothie maker It is important to plan appropriate surgical or radiation treatment field [75].
The benign fibrous lesions (fibromatoses) is a heterogeneous group of disorders with benign fibrous proliferative general characteristics of tumors (neoplasia) and the repair process. They can be localized or diffuse, symmetrical or not, spontaneous regression or recurrence. Fibromatoses usually detected in childhood, but they can occur in any age group. Although most benign place, pinched survival structures can occur [61]. They do not metastasize [76].
The cause of the fibromatoses smoothie maker not know, the classification of these lesions is mainly based on clinical signs of them. Although some of the lesions were classified as fibromatoses, this section refers only to desmoid fibromatosis, congenital fibromatosis, nodular fasciitis and proliferative fasciitis.
The term fibromatosis without any other definite commonly used to refer to desmoid fibromatosis (u sclerosis), is an infection u did not get the (fascia) limit. Rather, it grows from the structure - fat - nerves and connective tissue invasion. Some see them as pathological differentiated smoothie maker fibrosarcoma, especially when the mitotic figure was found scattered. Other abdominal wall desmoid primarily occurs in women, in the head and neck with no gender differences. They are found in all age groups, although the incidence was higher in the first few decades of life [74]. The Garner syndrome patients have an increased risk of developing desmoid rate.
These lesions are typically hard or solid and usually painless, although they sometimes soft. Most desmoid neck is at the top, lower the lesions are often difficult to treat because they may be related to the large blood vessels, smoothie maker trachea, and the arm plexus. We often invasive but not metastatic site (Figure 23) [61.74]. Surgery smoothie maker is the treatment of choice, and lesions usually smoothie maker clear boundaries beyond 2 to 3 cm, some cases do not clearly see the shore. Radiation therapy and chemotherapy for relapsed cases.
Figure 23. CT + C in (A) and bottom (B) shows a large heterogeneous mass (M) fills the left rear triangle of the neck and supraclavicular spread into the pit. T1-weighted images (C) in another patient showed cubic intermediate signal intensity in the left rear triangle of the left neck. Outer edge quite clearly, however, is not clear because the banks in its protruding rear larynx smoothie maker encase many scenes smoothie maker (arrowhead). T1 + C (D) in the same patient in (C) shows well defined blocks. T2-weighted (E) in a different patient shows high signal intensity mass in the left neck. Although banks are quite clear before, smoothie maker after infiltration over the banks. All patients with fibromatosis.
Fibrosis and systemic disease congenital (infantile myofibromatosis, fibroid disease of young-infancy) are rare diseases, beginning in the womb, however, other lesions in addition to continue to develop after birth. It manifested in the form of multiple areas of skin tumors and subcutaneous tissue. However, smoothie maker deep lesions related to heart, lung, muscle, organ and / or bone also occur, and many patients are unable smoothie maker to resist the disease. If the patient survived after a few months, the tumor usually spontaneous degeneration from the sixth month to 18 months [61].
