In contrast to common colonic epithelial neoplasms, polypoid mesenchymal tumors of the colon are extremely rare. The majority of uncommon gastrointestinal mesenchymal tumors are associated with the so-called gastrointestinal stromal tumors (GIST). We present a case of a rare colonic pleomorphic sarcoma, macroscopically mimicking a common epithelial colonic polyp, which did not match the criteria of GIST. In this case report we discuss the clinical and pathological characteristics of a rare polypoid-shaped, pleomorphic colonic sarcoma and refer a mark-off to other rare mesenchymal neoplasms of the gut.
与常见的结肠上皮性肿瘤不同，结肠息肉样间叶组织肿瘤极为罕见。大多数不常见的胃肠道间叶组织肿瘤与所谓的胃肠道间质瘤（GIST）相关。我们报告一例罕见的结肠多形性肉瘤病例，其在宏观上类似于常见的结肠上皮息肉，但不符合GIST的标准。在本病例报告中，我们讨论了一种罕见的息肉样、多形性结肠肉瘤的临床和病理特征，并将其与肠道其他罕见的间叶组织肿瘤进行鉴别。
