Angiomyofibroblastoma (AMFB) is an exceedingly rare mesenchymal tumor of the lower genital tract. AMFB primarily affects the pelviperineal region, especially the vulvar in premenopausal women. Typically, AMFB is a benign disease and does not have the potential for metastasis or recurrence, requiring complete surgical excision. Its accurate differentiation from aggressive angiomyxoma is critical due to varying prognoses. A 51-year-old woman, diagnosed with mucinous carcinoma of the breast, presented with a 12 cm abdominopelvic mass identified during breast cancer staging. Imaging suggested an ovarian origin; however, surgical exploration revealed a stalk-attached cystic mass in the anterior body of the uterus. Histopathology confirmed AMFB. Immunohistochemical analysis showed positivity for estrogen and progesterone receptors and smooth muscle actin. The patient continued breast cancer treatment postoperatively without pelvic mass recurrence or complications for a postoperative follow-up period of one year. This case highlights AMFB's potential uterine body origin, expending known tumor sites and complicating diagnosis due to overlapping features with other mesenchymal tumors. Accurate diagnosis using immunohistochemical markers and pathological features is essential to avoid unnecessary aggressive treatments. The uterine location in this case suggests a possible shared pathogenesis with uterine myomas, warranting further research into their connection. Reporting the first case of AMFB originating in the uterine body enhances understanding of this rare condition and underscores the importance of clinical awareness and precise diagnostic strategies to guide management and improve outcomes.

Introduction: We investigated the clinicopathologic features, method of treatment, and complications related to the conservative treatment and surgical treatment of patients with pelvic organ prolapse (POP)., Methods: We retrospectively analyzed 288 patients who were diagnosed with POP from January 2007 to December 2017. The patients were divided into two groups according to the treatment method (Group A received conservative treatment and Group B received surgical treatment). The patients' clinicopathologic characteristics, treatment method, and post-treatment complications were compared between groups A and B., Results: Of the total 288 patients, 83 and 205 patients were assigned to Groups A and B, respectively. The most common symptom was a bearing-down sensation (n = 205, 71.2%), which was reported in 51 (61.4%) and 154 (75.1%) patients from Groups A and B, respectively. Among underlying diseases, hypertension was the most common in both groups (40 and 102 patients in Groups A and B, respectively). Overall, 205 patients underwent surgery, 23 underwent vaginal pessary, and 60 performed pelvic floor muscle exercises. The incidence of treatment-related complications was not significantly different between Groups A and B (13.3% vs. 17.6%, p = 0.37). Perioperative complications were noted in 20 (17.8%) patients and vault prolapse requiring subsequent surgery was noted in 16 (14.1%) patients., Conclusion: As surgical treatment is associated with recurrence and complications, conservative treatment methods can be initially considered for patients with POP. In this study, there was no difference in the incidence of complications between surgical and conservative treatments. Thus, if required, surgical treatment can be safely performed in patients with POP., Competing Interests: The authors declare no competing interests., (© Hyen Chul Jo et al.)
