Multiple primary malignancies have an increasing incidence in the general population due to better diagnostic tools and the increased life expectancy. However, synchronous lesions are still rare and have a rate which varies between 0,17 and 0,69%. Second primary tumours usually develop after some time from the first cancer diagnosis. Although there is an arsenal of therapeutical options – the order and priority of the therapeutic choices are debatable and need to be tailored to every patient. The present paper illustrates the case of a 40 years old woman who presented to the emergency department with diffuse abdominal pain, nausea and bloating. The patient had done a fine needle biopsy of a suspicious lump in her right breast one week before the presentation and had no other relevant medical history. The CT scan revealed intraperitoneal free liquid with a paracolic mass at the rectosigmoid junction. The surgical team decided to perform an exploratory laparoscopy. At exploration, the mass was intensely adherent to the uterus and fixed to the pelvis.
Conversion to laparotomy and extemporaneous exam of the mass were undertaken, which revealed adenocarcinoma. En-bloc rectosigmoidian resection with hysterectomy and bilateral adnexectomy. The histopathology report staged the tumour as pT4N2M0 adenocarcinoma. Breast biopsy pathology report revealed no special type (NST) carcinoma, with luminal B breast cancer on immunohistochemistry. Clinical staging of the breast was cT1N0. After discussion of the case in the multidisciplinary team, it was decided for Madden mastectomy with axillary lymphadenectomy. Breast reconstruction with retropectoral expander was done in the same operating procedure. Post-mastectomy pathology report revealed pT1N0 and no metastases were present at standard imaging. The immunohistochemical profile of the resected breast tumour proved to be Luminal A. Adjuvant therapy consisted in chemoradiation for the rectum. The breast neoplasia was treated with tamoxifen as adjuvant therapy. Synchronous primary neoplasia exists and even if they have a low incidence once identified their treatment requires particular treatment for each case. A multidisciplinary approach is essential.
