Degenerated Primary Retroperitoneal Leiomyoma: A Rare Case

摘要

Summary Primary retroperitoneal leiomyomas are a very rare clinical condition. We present the case of degenerated primary leiomyoma in retroperitoneal area. A 33-year-old primiparous woman presented with chronic constipation. On examination, there was a large firm unpainful palpable lumbar mass in the left side. The diagnostic workup included contrast computer tomography, transabdominal ultrasonography, and colonoscopy that revealed a 7,5-cm heterogeneous retroperitoneal tumor in the left infrarenal area. At laparotomy, the mass arising from the retroperitoneum was excised. Histopathology showed a degenerated leiomyoma. Preoperative imaging can only give provisional diagnosis and can be misguiding. Considering current limitations in radiological diagnosis, surgical excision of these tumors is necessary to rule out malignancy. Top
