What is stromal hyperplasia?

Stromal hyperplasia, better known as pseudoangiomatous stromal hyperplasia (PASH), is a type of benign tumor resulting from the supporting tissue of cells and usually occurs in the breast. It was first discovered in 1986, when a team of three medical scientists recorded nine breast lesions. Since then, there have been very few cases of string hyperplasia, which has led to a lack of significant study study. These are cells that act as a hybrid between muscle cells known as fibroblasts and cells without or smooth muscles. Stromal hyperplay texture can be described as rubber and solid, consisting of fibrous and glandular tissue. Also, it does not provide any pain and is unilateral, which means that it occurs in one of the paired parts of the body. However, there are several cases in which the protrusion has appeared in both structures.It tumors that commonly appear in the breast. A distinguishing factor of string hyperplasia is its lack of malignancy. It was the ability to find out whether lesions are angiosarcoma or not, whichScientists allowed to separate string hyperplasia as a significant condition. Angiosarcoma refers to a collection of tumors characterized by uncontrolled growth and health hazards, followed by cancer. Although it can grow, stromal hyperplasia is not cancer.

Similarity of PASH and fibroadnoms sometimes make it difficult to diagnose both conditions, especially the first. The condition is usually diagnosed during a second or third visit to the medical center. Ultrasonography, mammography and displaying magnetic resonance imaging (MRI) are techniques used to diagnose stromal hyperplasia.

Doctors recommend surgery for patients with large PASH tumors. In some cases, the surgeon would continue to surgery, although the diagnosis does not confirm such a diagnosis as preventive measures against cancer. In the most extreme cases, mastectomy have been made to include complete breast removal. The sequence is recommendedEdge test, because there were situations in which the lesions were repeated.

Since its differentiation in the mid -80s. Although it is a benign, non -lawy state, the medical community has to determine its importance. Since there are very few documented cases of pseudoangiomatous stromal hyperplasia over the years, the possibility of deep research has been limited.
