Abstract
A sixteen year old boy complained of difficulty in tongue movements because of the presence of a tumor, which was gradually enlarged since his birth, at the left side the tongue. The tumor was removed surgically and was examined histologically. The histological examination revealed that tumor was composed of the tissue similar to that of normal tongue. Therefore the tumor was a developmental anomaly of rare occurrence and was not a so-called true tumor. No reccurence was observed three years after operation.
