Triple synchronous primary cancers of rectum, thyroid, and uterine cervix detected during the workup for hematochezia

Abstract

Multiple primary cancers are defined as multiple occurrences of malignant neoplasm of different histologic origin in the same individual. The synchronous occurrence of triple distinct cancers in the same patient is very rare. Herein, we report an extremely rare case of synchronous triple primary cancers of the rectum, thyroid gland and uterine cervix; all were detected during the work-up for hematochezia. To the best of our knowledge, this is the first such report in the medical literature. © 2010 The Japanese Society of Internal Medicine.
