Abstract:

Leiomyomatosis peritonealis disseminate (LPD) is a rare special type of uterine leiomyoma. At present, the pathogenesis is not clear, its incidence is extremely low, and the misdiagnosis rate is high. A case of abdominal diffuse leiomyoma admitted to Shandong Provincial Hospital Affiliated to Shandong University in 2021 was reported. The first symptom of this patient was frequent menstruation with increased menstrual flow. Before operation, it was not clearly diagnosed as LPD, and there was no clear indication from related auxiliary examinations. During the operation, it was found that many leiomyoma-like nodules of uterine fibroids diffuse in the abdominal cavity. LPD can be diffusely distributed on the surfaces of pelvic and abdominal organs, and it is difficult to distinguish it from peritoneal metastatic carcinoma or gastrointestinal stromal tumor with naked eyes. In addition, the symptoms are mostly related to the location of the lesion, and there is no specific manifestation. In practical clinical practice, the preoperative detection rate is extremely low. In order to reduce the misdiagnosis rate, patients with multiple history of uterine leiomyoma and laparoscopically crushed tumor should be alert, and if necessary, preoperative examination of pelvic and abdominal magnetic resonance imaging should be performed.
