We report a case of leiomyosarcoma of the renal vein, which is a rare tumor with no more than 30 cases found in the published English language literature. This case demonstrates encasement of the renal artery by the tumor mass, a previously unreported manifestation. The present study could be useful in considering this rare tumor in the differential diagnosis of renal hilar tumors. 相似文献

Retroperitoneal leiomyosarcoma mimicking acute appendicitis: laparoscopic management. 总被引:2,自引:0,他引:2

BACKGROUND: Retroperitoneal leiomyosarcomas (RLMS) are a challenging clinical entity. The vast majority of patients are operated on when tumors are advanced. We report herein a case of RLMS, mimicking acute appendiceal disease and treated successfully via laparoscopy. METHODS: A 37-year-old woman, para 1, was admitted to our department for right lower quadrant abdominal pain, fever, and leukocytosis. She had no changes in gastrointestinal and urologic function. A physical examination revealed the presence of abdominal guarding, rebound, and a tender mass in the right lower quadrant. The abdominal ultrasound showed an inhomogeneous ovoid mass (6 cm in diameter) located below the cecum, with no definite margins, and consistent with an appendiceal abscess. The patient was referred for laparoscopy. The procedure was performed with the aid of 3 ports: a 12-mm trocar in the umbilicus (open technique), a 10-mm trocar in the left iliac fossa, and a 5-mm one in the supra-pubic space. On inspection of the abdominal cavity, a retroperitoneal 6-cm mass was immediately found below the cecum and the appendix. Neither intraperitoneal seeding nor suspected lymph nodes were present. After dissection of the parietal peritoneum, the mass appeared to be encapsulated and well demarcated from all surrounding structures. It was eventually dissected and removed via a plastic bag. A standard appendectomy was also performed. The postoperative course was uneventful, and the patient was discharged on the 3rd day. The histology analysis of the resected specimen showed a totally excised G2 leiomyosarcoma. The appendix had no signs of inflammation. Postoperatively, the patient underwent a total-body CT-scan, which had no signs of residual or distant disease. No adjuvant therapy was necessary. At an 18-month follow-up, the patient was doing well and was disease free. CONCLUSION: Surgery represents the main therapeutic option for resectable RLMS. Laparoscopy is a useful diagnostic tool that allows safe resection of incidentally discovered, small and well encapsulated RLMS. 相似文献

影响胃平滑肌肉瘤预后的因素及外科处理 总被引:9,自引:0,他引:9
本文分析了50例经手术治疗的胃平滑肌肉瘤患者的临床病理特点及影响预后的因素,结果发现,胃平滑肌肉瘤的主要临床症状为腹痛和消化道出血。通过COX回归模型参数估计及显著性检验方法证实,本病预后与肿瘤大小、有无浸润邻近器官或转移,以及病理组织学分级明显相关,而与手术类型、切除范围、年龄、性别、局部浸润程度及肿瘤位置无密切关联。广泛的胃切除根治术中加宽无瘤边界以及区域淋巴结清扫并不优于局部切除术。 相似文献

Leiomyosarcoma originating in Meckel's diverticulum: Report of a case and a review of 59 cases in the English literature 总被引:1,自引:0,他引:1

A 49-year-old woman was referred to our hospital with complaints of epigastric colicky pain and high fever. Abdominal computed
tomography and ultrasonography showed a solid tumor in the lower abdomen. Laparotomy revealed a neoplastic mass arising in
Meckel's diverticulum; therefore, a segment of the ileum, including the tumor-possessing diverticulum, was resected with a
lymph node dissection. A histologic examination confirmed the lesion to be leiomyosarcoma. In the English literature, 59 cases
of leiomyosarcoma in Meckel's diverticulum were reported from 1941 to 1994. The majority of patients were in their 4th decade
of life, with both sexes equally affected. The most frequent symptoms associated with this disease were abdominal pain with
nausea, vomiting, and melena. The majority were larger than egg-size. Although Meckel's diverticulum is difficult to diagnose
preoperatively, mesenteric arteriography may at times prove useful. The standard management of this particular tumor is wide
segmental resection, including the tumor and diverticulum with lymph node dissection. 相似文献

The case of a 7-year-old girl with acquired immunodeficiency syndrome treated for 5 years with AZT and intravenous gamma globulin is reported. Shortly before her demise she developed a pulmonary leiomyosarcoma and leiomyoma. Does prolonged survival in pediatric acquired immune deficiency syndrome increase the incidence of secondary malignancies? 相似文献

Leiomyosarcoma of the vagina is quite rare. Extensive search of the literature discloses 137 case reports published over the past 40 years. Collectively, these reports give only cursory guidelines for diagnosis, management, and prognosis. We add another case to the sparse literature on leiomyosarcoma of the vagina. Treatment consisted of surgical excision. Tumor was found to extend to the margin of the excised specimen. The malignancy quickly recurred with lung metastases and the patient died. The very poor prognosis associated with this lesion emphasizes the critical need for early diagnosis and expeditious therapy. In the interest of improving salvage by prompt recognition and intervention, it is important for health-care professionals to be knowledgeable about and alert to this condition. 相似文献

Primary leiomyosarcoma of the thyroid gland 总被引:1,自引:0,他引:1
Osamu Ozaki Kiminori Sugino Takashi Mimura Kunihiko Ito Seiichi Tamai Yasuhiro Hosoda 《Surgery today》1997,27(2):177-180
Primary leiomyosarcoma of the thyroid gland is extremely rare, and to the best of our knowledge only five well-documented
cases have been reported in the world literature. We herein report a 58-year-old female patient with primary leiomyosarcoma
of the thyroid who was successfully treated by total thyroidectomy with a modified neck dissection. Immunohistochemically,
the tumor cells showed positive reactivity to α-smooth muscle actin and vimentin. Radical surgery was thus considered to be
essential in the treatment of this rare but rather aggressive malignancy. 相似文献
