The presence of per rectal (PR) bleeding in elderly people usually alerts us to the possibility of colonic malignancy, particularly if a concomitant altered bowel habit is present, without a history of the symptom. We present a case where the cause of PR bleeding turned out to be a caecal schwannoma. Caecal schwannoma is a rare tumour of the gastrointestinal tract of mesenchymal origin and diagnosis prior to radical surgical resection is difficult. Endoscopic biopsy often fails to provide an adequate specimen and immunohistochemistry is essential to the diagnosis.
老年人出现直肠指检(PR)出血通常会提醒我们注意结肠恶性肿瘤的可能性,特别是如果同时存在排便习惯改变且无该症状病史时。我们报告一例直肠指检出血的病因最终被证实为盲肠神经鞘瘤的病例。盲肠神经鞘瘤是一种罕见的间充质起源的胃肠道肿瘤,在根治性手术切除前很难诊断。内镜活检往往无法获取足够的标本,免疫组织化学对诊断至关重要。
