This paper presents on case of adenocarcinoma at the site of colostomy in a patient treated by abdominoperineal amputation five years earlier due to rectal cancer. The case raised the doubt as to whether the carcinoma represented a late, local recurrence or a second metachronic neoplasia. The most frequent location and pathogenesis of each were analyzed. The role of follow-up of these patients in detecting cases such as the one presented here are discussed.
We present a case of gastric leiomyosarcoma of special characteristics, given its clinical and pathologic divergence the existence of antecedents of sarcomatous neoplasm previously excised in the same patient. We emphasize the association of these tumors with the appearance of malignant neoplasms in other sites previously, synchronically or metachronically, and the necessary preoperative staging, based fundamentally on CAT and endoscopy, to establish the therapeutic approach according to the predicted behavior of these tumors.
