Leiomyosarcomas are rare aggressive smooth muscle tumors that represent 0.1% of all colorectal malignancies. The lack of literature available concerning leiomyosarcomas presents a challenge when diagnosing and treating these tumors, thus it is crucial that we differentiate them from gastrointestinal stromal tumors (GIST), the most common type of mesenchymal neoplasms of the gastrointestinal (GI) tract, especially when considering leiomyosarcoma's high prevalence of recurrence and malignancy. In this article, we present a case of a 74-year-old male with a diagnosis of colonic leiomyosarcoma. We analyze the tumor's CT imaging findings as well as correlation with the patient's pathological findings including immunostains, size, and mitotic activity, as well as the patient's risk for recurrence.
平滑肌肉瘤是罕见的侵袭性平滑肌肿瘤，占所有结直肠恶性肿瘤的0.1%。由于缺乏关于平滑肌肉瘤的文献，在诊断和治疗这些肿瘤时面临挑战，因此，我们将其与胃肠道间质瘤（GIST）区分开来至关重要，胃肠道间质瘤是胃肠道（GI）最常见的间叶性肿瘤类型，尤其是考虑到平滑肌肉瘤的高复发率和恶性程度时。在本文中，我们报告了一例74岁男性诊断为结肠平滑肌肉瘤的病例。我们分析了肿瘤的CT影像学表现，以及与患者病理结果的相关性，包括免疫组化、大小、有丝分裂活性，以及患者的复发风险。
