Clinical and Pathological Analysis of 1 Case of Ovarian Goiter with Peritoneal Lesion

Abstract

Objective: To study the clinical and pathological characteristics of a case of ovarian goiter with peritoneal lesion. Methods: Analysis of the clinical and pathological data of one case of ovarian goiter with peritoneal lesion at our hospital. Results: Pelvic CT scan showed an irregular cystic-solid mass in the pelvis, approximately 11.6x10.3x8.8cm in size, with patchy highdensity shadows and calcified density shadows within it, poorly demarcated from the uterus and both adnexa, with moderately enhanced walls. Multiple lymph nodes were seen around it, the larger ones measuring about 1.1cm in short diameter, with mild to moderate enhancement; Total hysterectomy + bilateral salpingo-oophorectomy + peritoneal lesion resection was performed. Postoperative pathology diagnosed well-differentiated thyroid tissue with thyroid swelling changes in the ovarian area, fallopian tube wall, uterine serosa, and (peritoneal lesion). Given the patient’s history of “pelvic mass” resection, thyroid follicular carcinoma metastasis could be ruled out, suggesting the possibility of ovarian goiter with extronic tissue involvement. No BRAFV600E, K-RAS, or N-RAS gene mutations were detected. Ultrasound of both thyroid glands and cervical lymph nodes showed no significant nodules or masses. The patient has been tumor-free since surgery. Conclusion: The pathological features of ovarian goiter with peritoneal lesion include benign histological manifestations similar to nodular goiter, and the peritoneal lesion is welldifferentiated thyroid tissue with thyroid swelling changes: no BRAFV600E, K-RAS, or N-RAS gene mutations were detected.
