Peripheral squamous odontogenic tumor masquerading as oral squamous cell carcinoma in an elderly female patient: A rare entity

Squamous odontogenic tumor is a rare epithelial odontogenic tumor. Only a few cases have been reported in the literature, out of which central cases occurring within the jawbones are more common, and very rarely peripheral cases have been reported. Here, we report a rare case of a peripheral squamous odontogenic tumor occurring in the left lower gingivobuccal sulcus region in a 63-year-old female patient and presented as a firm and fibrotic swelling clinically. Radiographic examination revealed no evidence of a central lesion in the bone. Excisional biopsy of the lesion revealed the characteristic histopathological picture of peripheral squamous odontogenic tumor (PSOT). The healing was found to be satisfactory upon periodic evaluation of the patient done to study the healing and for any recurrence of the lesion.
