Maria Jose's Sister's lump (metastatic umbilical carcinoma) is a metastasis of more than one malignant tumor (frequently abdominal), but on occasions it is the first sign of disease. A case of a female patient diagnosed as having "umbilical hernia" with peritoneal carcinomatosis, liver metastasis and "frozen pelvis", who died 6 months later, is presented, demonstrating the bad prognosis of this sign.
