Primary Diffuse Large B-Cell Lymphoma of the Appendix: A Case Report and Review of the Literature

摘要: 淋巴瘤是起源于淋巴造血系统的恶性肿瘤，阑尾原发性淋巴瘤发病率极低，比较罕见。阑尾淋巴瘤的临床表现缺乏特异性，容易误诊。本例患者男性，31岁，因右下腹间断性疼痛3个月，外院B超检查发现右下腹阑尾囊性包块而入院。临床行阑尾炎切除术，术中发现阑尾头部有一个大小约7.0 cm × 4.0 cm的肿块，手术后病理诊断为阑尾原发性弥漫性大B细胞淋巴瘤。患者术后行化疗，随访已18个月，病情无进展。

Abstract: Lymphoma is a malignant tumor originating from the lymphatic hematopoietic system. Primary lymphoma of the appendix has a very low incidence and is relatively rare. The clinical manifestations of appendiceal lymphoma are lack of specificity and easy to be misdiagnosed. This case is a 31-year-old male patient, who was admitted to the hospital due to intermittent pain in the right lower abdomen for 3 months. B-ultrasound examination in the external hospital found a cystic mass in the right lower abdomen appendix. Clinical appendicitis resection was performed. During the operation, a mass of about 7.0 cm × 4.0 cm was found in the head of the appendix. The pathology was diagnosed as primary diffuse large B-cell lymphoma of the appendix after the operation. The patient underwent postoperative chemotherapy and was followed up for 18 months without any progress.
