title: Recurrent uterine leiomyosarcoma: an atypical location.
abstract: Leiomyosarcoma (LMS) is a malignant tumor of smooth muscle cells and comprises 5-24% of all soft tissue sarcomas. Although the most frequent symptoms are vaginal bleeding and abdominal pain, the symptoms are generally associated with dimensions and localization of the tumor. The current study presents a case of uterine leiomyosarcoma that metastasized to the rectus abdominis muscle, which has only been previously reported in two cases in the literature. A 57-year-old multigravid patient presented with a palpable mass in her abdomen. The patient's past medical history revealed a hysterectomy performed in another center seven years ago with a postoperative histopathological report of leiomyosarcoma. A myomatous mass was detected, which was localized at the distal part of the right rectus muscle during operation. The mass was completely excised. The case was diagnosed as leiomyosarcoma according to the histopathological findings. Any mass in a skeletal muscle should be suspected to be metastasis in patients with a prior history of aggressive gynecologic malignancy such as LMS.
