Atypical pattern of rectal cancer metastasis into mouth cavity

Metastasis is one the most common pathways of progression of rectal cancer. Rectal cancer metastases spread through lymphatic and blood vessels, giving metastases generally into locoregional lymphatic nodeslymphogenic metastasis and also liver and lung-hematogenic metastasis. The metastasizing process depends on creation of premetastatic niche-giving the cancer cells a prolific condition. A case of 73 years old male patient with a rectal cancer and metastases in locoregional lymphatic nodes and an atypical metastasis in the gingiva of the maxillary premolars had been accepted in the clinic of General and Liver-Pancreatic Surgery, University Hospital Alexandrovska, Sofia, Bulgaria.
