Colonic mucinous adenocarcinoma with atypical metastasis

Abstract

In 2002 a right hemicolectomy was performed in a 70-year-old male with cecal cancer. Histologically it was a well-differenciated mucinous adenocarcinona (Dukes C stage, pT3pN1pMx, tumor free margins). Adjuvant therapy was chemotherapy. In January 2007, during the surgical treatment of right hidrocele testis, the discovery of a large hard mass determined a right orchidectomy. The result of the pathologic analysis was adenocarcinoma with probable origin in the gastro-intestinal tract. In March of the same year the patient was subjected to excision of the spermatic cord and linfadenectomy. The histologic analysis revealed multiple foci of mucinous adeno-carcinoma with probable colic origin and tumor free margins. The exploratory laparoscopy did not show any peritoneal metastasis. In 2008 and 2009 several right inguinal cutaneous metastasis were excised. The patient started radiotherapy in 2009 after the presentation of right paratesticular and perineal metastasis.
