The majority of plasma junction tumors with microinfiltration in small focal areas can be eradicated, and a few have a poorer prognosis. Microinfiltration of small focal areas of plasmacytoid junction tumors refers to ovarian junction plasmacytoid tumors, which usually develop on both sides and are more than 1 cm in diameter, with localized papillary growths in the inner wall of the capsule, and in a minority of patients, it may be a papilla on the surface of the ovary. If observation is made with endoscopy, the papillae can be seen branching step by step, the nuclei are heteromorphic, and there are relatively few nuclear divisions, in this case the prognosis is good, and it can be eradicated by surgical methods. If ovarian junctional plasmacytoma is observed endoscopically as a micropapillary variant characterized by elongated unbranched papillae, this situation is similar to low-grade plasmacytoma, and the prognosis is poorer and may not be curable. When micro-infiltration of small foci of plasma junction tumors occurs, it is recommended to seek medical treatment in time, improve relevant examinations, and actively cooperate with doctors for treatment. Generally, the earlier the treatment, the better the prognosis is. According to whether the patient has the requirement of reproduction or not, the professional doctor will choose the suitable operation method.
