Metastasis to ileostomy of mucinous adenocarcinoma of rectum.

Carcinoma of colon and rectum is one of the most common malignancies of gastrointestinal tract. Primary ileostomy cancer following excision of primary tumour is a rare complication although a number of cases have been reported in the last 30 years. This case also reports lymph node metastasis to the adjacent mesenteric lymph nodes. Appearance of ileostomy tumour as synchronous or metachronous lesion is highly debatable. Once diagnosis is confirmed by biopsy enblock excision with or without stomal relocation is the main stay of treatment. Patient education and regular surveillance of patients with long-standing ileostomy is recommended for early detection of this unusual cancer.
