Plasmacytoid mastitis usually recurs after surgery, which is determined by the pathological basis of plasmacytoid mastitis. The lesion is most likely due to the dilation of the breast ducts for various reasons, and there may be a large infiltration of inflammatory plasma cells around the breast area, spreading to the surrounding normal breast ducts, which may result in the recurrence of the lump after it has healed and another one after it has appeared. In the case of large lumps, Western medicine usually controls the inflammation first and then removes the lump, which may lead to recurrence and is indeed a difficult problem in clinical treatment. Therefore, for this disease, a combination of Chinese and Western medicine is recommended. With the advantages between the two, it may shorten the disease and reduce the patient’s treatment time.
