[Primary adenocarcinoma at a colostomy site]

The colostomy opening is a very rare site of the large bowel cancer. There is only one case report in the world literature and none in the Hungarian one. The authors report a case of a 51 year old man, who presented a typical malignant growth in his colostomy opening, created 24 years before due to a rectal lesion considered as an inoperable cancer, though not proved histologically. Later the patient was treated by telecobalt irradiation, and the growth perfectly disappeared. Now the second, metachron malignancy arising from the colostomy has been removed and the patient is symptom free four years after the operation. Emphasizing the importance of postoperative follow-up in cases of gastrointestinal malignancies the authors considered this case as an unique but instructive one.
