Not always a distant metastasis: Can be a double maliganancy too

Abstract

The incidence of double malignancy reported are between 0.3% and 4.3%. The second primary lesion is identified either simultaneously with the primary lesion (synchronous) or after a period of time (metachronous). We report a case in a 63-year-old male presenting with double malignancy with adenocarcinoma of the ascending colon and a pre- sacral Chordoma of which the latter was detected accidentally on imaging. The patient underwent surgical excision of the pre-sacral mass and an exploratory laparotomy with Right Hemicolectomy. The increasing incidence of multiple malignant tumors is a real challenge to both clinicians and pathologists and close attention should be paid to imaging and histologic findings to avoid a misdiagnosis. In addition an early diagnosis is essential to achieve optimal treatment. We believe that the treatment modalities should be carefully tailored for each individual patient diagnosed with a double malignancy.
