以肠结核表现为伪装症状的结肠低分化腺癌病例报告

Case Report of Colonic Poorly Differentiated Adenocarcinoma Masquerading as Intestinal Tuberculosis

摘要: 本文报道一例罕见19岁男性乙状结肠低分化腺癌伴印戒细胞特征病例。患者表现为腹痛、腹泻及体重减轻，影像学提示腰大肌寒性脓肿及肠壁狭窄，临床高度疑似肠结核。术后病理确诊为印戒细胞癌，揭示了该肿瘤极具迷惑性、可完美模拟肠结核等炎性疾病的特点。案例警示对于青年患者，即使影像学支持良性病变，也需在鉴别诊断中高度警惕恶性肿瘤，以避免诊断延误。

Abstract: This paper reports a rare case of poorly differentiated adenocarcinoma of the sigmoid colon with signet ring cells in a 19-year-old male. The patient presented with abdominal pain, diarrhea and weight loss. Imaging showed a cold abscess of psoas major and intestinal wall stenosis, which was highly suspected of intestinal tuberculosis. The pathological diagnosis of signet ring cell carcinoma after operation revealed that the tumor was very confusing and could perfectly simulate inflammatory diseases such as intestinal tuberculosis. Case warning for young patients, even if imaging supports benign lesions, we should be highly alert to malignant tumors in differential diagnosis to avoid delay in diagnosis.
