- clinical picture
Sinovioma - a group of tumors originating from the synovial bags, synovial joint and synovial sheaths.Sinovioma is malignant and benign.
Benign synovioma - a rare phenomenon.Its existence is disputed by scientists for a long time.It occurs education equally in men and women, as a rule, from 20 to 40 years.Localization is mainly observed near the fingers.Clinical signs of little pronounced, as the tumor does not cause pain to the patient and does not disturb the function of the limb.Treatment of benign tumor is its extensive excision.Weather favorable for life with the possibility of recurrence, which occur in 17-43% of cases.Relapses can be explained by the fact that in some cases it is impossible to remove the tumor completely.
The share of synovitis cancer accounts for about 10% of all soft tissue sarcomas.Usually the disease occurs in men between 20 and 40 years old.The most frequent localization Sinovioma observed in the joints o
A detailed investigation clearly that education has a limited view of shapeless mass of large dimensions.Diameter can reach 10 cm and over.In terms of tumor uniform, soft and supple with are areas of bone calcification, cartilage and cysts.
Histologically in Sinovioma are two types of cells - spindle-shaped fibroblast-like and cube-shaped, polygonal or cylindrical.If the swollen dominates any one species, then we say that the formation of single phase and a relatively equal number of cells - biphasic structure.In Sinovioma characterized by glandular structures.
The most common symptoms include: pain, swelling.Functional disorders are mild or absent altogether. In some cases, the clinical picture is manifested in the form of compression and sprouting nerve or bone disease.Malignant synovioma has a latent period of the current - about 2 years, during which it is virtually impossible to diagnose.Using X-rays to determine synovioma difficult because the same features are typical of other soft tissue sarcomas, as well as some nonmalignant diseases.
Using X-rays can be specified place of localization of tumors, its size, stage distribution and shape of the tumor.For a more complete diagnostic method used Sinovioma bezekrannoy radiography xeroradiography, arthrography.When deep-lying formation used pneumography and angiography.
Node single tumor located near the joint, but occasionally away from him.Education in the form of round and oval, has a clear smooth contours, while the expansive growth of polycyclic contours.When Sinovioma ingrowth into surrounding tissue or recurrent contours of her fuzzy.In half the cases in the background node tumor visible inclusions fine structureless calcifications, less homogeneous areas of ossification.
Treatment of tumors occurs by excision of it within the integrity of tissues or produce amputation.The method of radiation therapy and chemotherapy usually is not very effective, but still requires further investigation.Forecasts for adverse life.Statistically survive after 5 years of treatment in 23-51% of all cases.There are, in most cases of recurrent relapses.
