The most common type of carcinoma associated with ulcerative colitis (UC) is adenocarcinoma. We present a case of primary rectal small cell carcinoma in a patient with a history of UC.
A 34-year-old male diagnosed with UC for 10 years was not consistent with the usual annual follow-up and presented with mucoid-bloody diarrhea. Colonoscopy revealed a rectal mass 2 cm distant from the anal verge. The patient underwent a total proctocolectomy with preservation of the anal sphincters, construction of an ileal reservoir, anastomosis of the reservoir to the anus (J configuration) and protective loop ileostomy.
Histological examination showed undifferentiated small cell carcinoma.
This is the first case of small cell carcinoma in a background of UC reported to be treated surgically and the patient and has no recurrence 18 months postoperatively.
与溃疡性结肠炎(UC)相关的最常见的癌为腺癌。我们报告了一例 UC 病史患者的原发性直肠小细胞癌。
一名 34 岁男性,UC 病史 10 年,未进行常规年度随访,出现黏液脓血便。结肠镜检查显示距肛门 2cm 处直肠有一肿块。患者接受了全直肠结肠切除术,保留肛门括约肌,行回肠储袋构建,储袋与肛门(J 型)吻合,并保护性回肠造口术。
组织学检查显示未分化小细胞癌。
这是首例报道的 UC 背景下的小细胞癌经手术治疗的病例,患者术后 18 个月无复发。
