Abstract
Squamous odontogenic tumor-like proliferation (SOTP) is a peculiar but benign lesion of the jaw-bone that was first described by W right in 1979. It is sometimes very difficult to differentiate such a lesion from true squamous odontogenic tumor (SOT) by histopathological examination alone.
This study is based on the histopathological and histochemical findings concering an SOTP lesion that was associated with a radicular cyst in the premolar region of the mandible of a 42-year-old Japanese woman. The results indicate that to clarify the biological nature of SOTP, further investigation concerning the pluripotentiality of the odontogenic epithelium is necessary.
This is the first case report of SOTP in Japan.
