Multiple primary malignant tumors (MPMNs) are not rare entities. We report a case of a 50-year-old female who presented with left upper quadrant abdominal pain and GI bleeding. Initial assessment with CT scan revealed a mass originating from the descending colon. Colonoscopy was performed and a fungating partially obstructed mass at the left splenic flexure was detected. Histopathological examination of biopsy was consistent with mucinous adenocarcinoma. The staging CT scan of the chest and pelvis, followed by a mammogram reported a Synchronous breast mass. Core needle biopsy detected an invasive ducal carcinoma. In the multidisciplinary meeting, it was decided to perform the colon procedure first, followed by adjuvant chemotherapy, and then the breast procedure. The patient had an uneventful recovery after both procedures and was sent to the medical oncology department to continue with the treatment.
多原发性恶性肿瘤（MPMNs）并非罕见病例。我们报告一例50岁女性，她因左上腹疼痛和胃肠道出血就诊。CT扫描初步评估发现一个起源于降结肠的肿块。进行了结肠镜检查，在脾曲处发现一个呈蕈状、部分阻塞的肿块。活检的组织病理学检查结果与黏液腺癌相符。胸部和骨盆的分期CT扫描以及随后的乳房X光检查报告发现一个同步性乳房肿块。粗针活检检测到浸润性导管癌。在多学科会议上，决定先进行结肠手术，然后进行辅助化疗，接着进行乳房手术。两次手术后患者恢复顺利，并被送往医学肿瘤科继续治疗。
