title: Duodenal obstruction from isolated breast cancer metastasis: a case report.
abstract: Metastatic involvement of the upper gastrointestinal tract from breast cancer has been reported in autopsy series as occurring in more than 15% of patients, usually associated with extensive systemic spread; clinical manifestations from such metastases have been described in less than 1% of cases. Lobular infiltrating carcinoma seems to have a different metastatic pattern than the ductal type, with an apparent predilection for the gastrointestinal tract. Metastatic presentation as an isolated intestinal obstruction without other signs of metastatic spread is extremely rare. We present a case of isolated duodenal metastasis from breast cancer, associated with intestinal obstruction, as the first sign of metastatic spread.
