Most prostate tuberculosis invades both sides at the same time.Early tuberculous lesions appeared near the vascular, underlike, duct or ejaculation pipe port near the prostate and seminal vesicles, and can be extended to the leaves, seminal vesicles, or epididymis on both sides of the prostate.Like the tuberculosis of other parts, the prostate tuberculosis was transformed in the early stage, and there were small and dense tuberculosis nodules around the blood vessels.The further development of submucosal lesions can cause adenoid epithelial damage and disappear, forming tuberculosis granuloma and cheese.The cheese area can be found in any part of the prostate, which is necrotic in the middle, and surrounded by epithelial giant cells around.Finally, liquefaction or abscess formation, the necrotic tissue is left out of the empty tissue from the prostate duct.During the repair, the fibrous tissue replaces the tuberculosis. The entire glandular fibrosis causes the prostate to increase, with nodular and irregular, which is closely adhesive to the surrounding organs, which is similar to that of cancer.
When the lesion is severe, it can be extended to the surrounding tissue of the prostate, which disappears the normal tissue of the semen, dense tuberculosis tissue, a wide range of cheese -like lesions, and can narrow the end of the ureter.If the abscess is formed, it can be broken to the perineum and become a durable sinus.It can also be broken into the bladder, urethra or rectum.
In the end, the prostate tuberculosis will be secondary infection or healed by calcification.Observation under a microscope, the tuberculosis of the prostate is a typical tuberculosis nodule, including cheese -like necrosis in the central area. The surrounding epithelial cells, tissue cells and Langhan giant cells, lymphocytes peripheral lymphocytes and fibroblasts formedNodule.There was no necrotic center in the early stage of the lesion, but only a small nodule formed by tissue cells around the gland, the center was giant cells, and the surrounding was lymphocytes.The entire glandular body changes in chronic inflammation.
