Abstract
BackgroundThe presentation of synchronous multiple primary tumors is rare. The aim of this report was to report an uncommon series of cases diagnosed with synchronous gastrointestinal tract carcinoma and other solid malignancies by multidetector computed tomography.Case presentationOur report included 34 patients with synchronous gastrointestinal tract carcinoma and other solid malignancies from November 2009 to September 2019. They were 14 men and 20 women (mean age, 65.5 year; range, 52–82 years). The highest number of GIT cases were colonic carcinomas detected in 70% (24/34) of the patients. The most frequent extra-gastrointestinal primary malignancy sites were renal cell and breast carcinomas, 17.6% (6/34) of each.ConclusionsCareful preoperative evaluation is recommended to detect this pattern of synchronous extra-gastrointestinal tumors. More reports of such cases should help to clarify the pathogenesis of this phenomenon and may lead to a new treatment strategy for synchronous gastrointestinal malignancy and other solid malignancies.

Careful preoperative evaluation is recommended to detect this pattern of synchronous extra-gastroin‐ testinal tumors. More reports of such cases should help to clarify the pathogenesis of this phenomenon and may lead to a new treatment strategy for synchronous gastrointestinal malignancy and other solid malignancies
The incidences of multiple primary malignancies have increased in recent years due to the increasing proportion of elderly patients in the general population, regular medical check-ups, and the increased number of cancer survivors [1]
Summary
Careful preoperative evaluation is recommended to detect this pattern of synchronous extra-gastroin‐ testinal tumors.
