A case of familial colic polyposis concurrent by mesenteric leiomyoma was experienced. The patient was a 34-year-old woman, who received total colorectectomy and ileostomy for familial colic polyposis two years earlier. An abdominal tumor pointed out 17 months postoperatively induced us to attempt tumorectomy, which however, ended in simple laparotomy. Biopsy revealed mesenteric leiomyoma. Gardner's syndrome is known to be concurrent by various types of diseases not only of the digestive tract, but also of other panblasto-originating organs, but may rarely be concurrent by mesenteric leiomyoma. The pathogenesis of benign tumorous lesions concomitant with Gardner's syndrome presumably but not definitely involves a congenital anomaly somewhere in the tissue repair mechanism, leading to abnormal tissue hyperplasia. In the present case, there is a possibility of surgically induced mechanical stimulation of the mesentery, leading to abnormal tissue hyperplasia and subsequent mesenteric leiomyoma.
