Primary leiomyosarcoma of the pancreas is a very rare malignant tumor, with only 12 cases reported. A case of primary pancreatic leiomyosarcoma in a 55 year-old female with diabetes mellitus is described. US and CT demonstrated tumor masses in the head and tail of the pancreas. By angiography, abundant tumor vessels corresponding to the pancreatic tumor masses were revealed in the pancreas. The patient underwent surgical resection of the tumor in the tail of the pancreas, and then, microscopically it was diagnosed as leiomyosarcoma. The tumor in the head of the pancreas was not resected on account of the presence of diabetes mellitus and the possibility of poor prognosis. Macroscopically, it seemed to be the same as the tumor in the pancreatic tail. By operative findings, there was invasion from the pancreatic head to the duodenum and there was nothing to justify suspicion of the extra-ductal growing type of primary leiomyosarcoma of the duodenum. There were no metastases noted at the time.
胰腺原发性平滑肌肉瘤是一种非常罕见的恶性肿瘤，仅有12例病例报道。本文描述了一名55岁患有糖尿病的女性原发性胰腺平滑肌肉瘤病例。超声和CT显示胰腺头部和尾部有肿瘤肿块。通过血管造影，在胰腺中发现了与胰腺肿瘤肿块相对应的丰富肿瘤血管。患者接受了胰腺尾部肿瘤的手术切除，随后经显微镜检查诊断为平滑肌肉瘤。由于患者患有糖尿病且预后可能较差，胰腺头部的肿瘤未进行切除。肉眼观察，其似乎与胰腺尾部的肿瘤相同。根据手术所见，肿瘤已从胰腺头部侵犯至十二指肠，且没有理由怀疑为十二指肠原发性平滑肌肉瘤的导管外生长型。当时未发现转移情况。
