SURGICAL DISEASES, TRAUMATOLOGY, ORTHOPEDICS, UROLOGY : FIBROADENOMA OF THE MAMMARY GLAND (FIBROADENOMA MAMMAE) - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
The etiology is unclear.
The pathogenesis. Of benign breast tumors are the most frequent tumors of mixed character: fibroadenoma, less cystadenoma and systemically.
The tumor often develops at the age of 20 - 25 years in the outer sector of the gland. Histologically consists of epithelial tissue with predominantly located around the acini of the connective tissue. Sizes small.
Symptoms. A tumor with a smooth surface, elastic or thick consistency, not associated with skin and smash of deep tissues, is well separated from the glandular tissue and subcutaneous tissue, characterized good mobility, slow-growing, located more perifericheskie.
For. Growing fibroadenoma slowly, sometimes over many years. Distinguish:
1) fibroadenoma with live proliferation of the epithelium,
2) fibroadenoma with the proliferation suspicious for transition in cancer,
3) fibroadenoma beginning cancerous changes,
4) fibroadenoma with a clear transition in cancer.
Recognition facilitates plurality and prolonged course, no change in the position of the gland, venutolo nipple, the presence of istonchennoy skin and its mobility over the tumor. The transition in cancer likely during rapid growth, the appearance of the nipple discharge (bloody and standard procedure we iron), with the loss of tumor mobility and cohesion with the surrounding tissues.
