We report herein the case of a patient in whom metastatic colon carcinoma was found within an inguinal hernia sac. According to Lejar's classification, colon carcinomas within inguinal hernias are categorized as intrasaccular- and saccular-type tumors. In our patient, asymptomatic transverse colon carcinoma was the primary lesion, and to the best of our knowledge, this is only the fourth case of such a saccular-type tumor to be reported in the literature. To date, 21 cases of intrasaccular tumors have been reported, and saccular-type tumors are considered to be an even rarer entity, unless the patients have obvious ascites, indicating peritonitis carcinomatosa. Histologic examination of the hernia sac is recommended for male patients of advanced age with an inguinal hernia, especially those who have previously undergone surgery for colorectal carcinoma.
我们在此报告一例在腹股沟疝囊内发现转移性结肠癌的患者。根据Lejar分类，腹股沟疝内的结肠癌分为囊内型和囊型肿瘤。在我们的患者中，无症状的横结肠癌是原发性病变，据我们所知，这是文献中报道的此类囊型肿瘤的第四例。迄今为止，已报道21例囊内型肿瘤，囊型肿瘤被认为是一种更为罕见的实体，除非患者有明显腹水，提示癌性腹膜炎。对于老年男性腹股沟疝患者，尤其是那些既往接受过结直肠癌手术的患者，建议对疝囊进行组织学检查。
