[A woman with an umbilical swelling].

A 78-year-old woman presented with a 9-month history of an ulcerative umbilical swelling, which had recently started to produce feces. An abdominal CT-scan showed a tumour in the transverse colon, infiltrating the abdominal wall and skin, but without signs of distant metastases. Histopathological examination of a biopsy specimen revealed a slime-producing adenocarcinoma. Due to a myocardial infarction, the patient died two days prior to surgery. No permission to conduct an autopsy was granted.
