Advanced primary fallopian tube cancer was found during chemotherapy for multiple myeloma: a case report and literature

The coexistence of MM and primary fallopian tube carcinoma is an extremely rare occurrence. When a pelvic mass is detected in patients with multiple myeloma, it is important to consider the possibility of a second primary tumor in addition to myeloma metastasis. Managing patients with this dual malignancy presents a significant challenge for clinicians. Treatment plans should be developed through multidisciplinary collaboration, taking into account the severity of the disease and the patient's physical condition. Close monitoring is necessary during the perioperative period, as these patients are susceptible to infection and kidney damage. It is advisable for patients and their children to undergo genetic testing in order to implement appropriate preventive measures.
