Abstract
Sialendoscopy is a minimally invasive technique used mainly in the diagnosis and treatment
of obstructive salivary gland disorders. There has yet to be a report on its use in
the diagnosis of metastatic disease. While metastatic cancer has been described in
numerous head and neck anatomic subsites, it has not been reported to be found in
a mucous plug in Stensen’s duct. Sialendoscopy was performed in a 68-year-old female
patient who presented with symptoms of ductal obstruction. Basket removal of a mucous
plug was done and histopathological analysis of this specimen found adenocarcinoma.
The overall clinical picture, imaging, and final histopathological results suggested
that this patient had metastatic breast carcinoma to a mucous plug in Stensen’s duct,
the diagnosis of which was made with the aid of interventional sialendoscopy. This
is the first report in which metastatic cancer was identified in a mucous plug in
Stensen’s duct. Sialendoscopy can be a useful tool to aid in the diagnosis of metastatic
diseases in rare and unusual clinical situations.
