【摘要】 目的了解肛管直肠恶性黑色素瘤的诊断和治疗,预防以后工作中对该病在诊断和治疗上出现错误。方法与结果收集1972～1989年间9例肛管直肠恶性黑色素瘤男3例,女性6例; 年龄47～76岁;发生在齿线上7例,肛管2例;肿瘤3.0×3.0×2.5～7.0×5.5×3.0。除肺、肝有转移各1例未行手术治疗,6例行Miles手术,1例剖腹探查,病理诊断为肛管直肠恶性黑色素瘤7 例,肛管恶性黑色素瘤2例。侵基底及肛管直肠纵径为3～7cm,周径1／4～2／3。结论肛管直肠恶性黑色素瘤临床少见,易误诊为“腺瘤”或“癌”。治疗以手术为主,初次手术应较彻底地切除原发病灶、淋巴结及其周围受累组织,术后配以综合治疗,本病对放疗不敏感。本病恶性程度高,转移快,预后差。更多还原

【Abstract】 Objective Understand diagnosis and treatment of anorectal melanocaricinoma, prevent misdiagnosis. Methods and Results Collect 9 cases of anorectal melanocaricinoma from 1972 to 1989,3 cases were male, 6 cases were female: age from 47 to 76 years old; 7 cases and 2 cases lay above dentate line and in anale canal respectively. The size of the tumor was 3.0×3.0×2.5～7.0×5.5×3.0. Except two cases were not operated because of metastasis to the lung and the liver respectively were not operated, 6 cases with Miles and one case with dxploratory operation. By pathologic diagnosis, there were 7 cases of anorectal melanocaricinoma and 2 cases of anale canal melanocaricinoma. The length of the invasive basis and anorectal was 3～7cm, its caliber was 1/4～2/3. Results anorectal melanocaricinoma is so rare in clinic that it is easy to be diagnosed erroeously to be adenoma and cancer. So it is mainly treated with poeration, firstly primary focus should be removed complotely, then lymphnode and its tissues should be treated synthetically after poeration. But this disease is not sensitive to radiotherapy and it has the characteristic of high malignancy, quick metastasis and worse prognosis.更多还原
