The primary intra-osseous carcinoma (PIOC) is a very rare lesion. PIOC is an
odontogenic carcinoma defined as a squamous cell carcinoma arising within a jaw
having no initial connection with the oral mucosa, and presumably developing from
residues of the odontogenic epithelium. The authors diagnosed a 51-year-old female as
primary intra-osseous carcinoma after undergoing clinical, radiological and histological
examinations.
The characteristics were as followed:
1. The patient complained of gingival bleeding on the premolar area in the left maxilla
2. The conventional radiograms showed a relatively well-defined unilocular radiolucent
lesion from the mesial aspect of the upper left canine to the mesial aspect of the upper
left 1st molar. The End premolar was separated from the 1st molar and the floor of the
maxillary sinus was elevated by the lesion. There was a extemal root resorption of the
upper le(t canine , the 1st premolar, and the 2nd premolar.
3. On the coNlputed tomograms, the osteolytic bony lesion expanded the cortical plate
of the left maxilla and displaced the margin of the left maxillary sinus upwards. But the
bony lesion was separated from the maxillary sinus by a bony septum.
4. Bone scintigram with 99mTc demonstrated the increased uptake in the
left maxilla. Sonograms in the neck area and chest P-A radiogram didn't show any
abnormalities.
5. Histologically, the tumor islands infiltrating into the surrounding bone increased in
alveolar pattern, composed of the malignant cells, and there was a necrosis in the center
of the tumor islands.
