Salivary duct carcinoma metastasizing to the small bowel.

We report a case of salivary duct carcinoma in a 47-year-old woman. The patient presented with symptoms simulating acute appendicitis. Surgery revealed metastatic tumor in the wall of the small bowel. Two months later, a tumor of the right parotid gland was resected, and histologic analysis revealed a salivary duct carcinoma. To our knowledge, this is the first case of salivary duct carcinoma metastasizing to the small bowel with manifestations of metastatic disease as the prominent symptom.
