This is the third part of a review of the clinicopathologic features of intraosseous carcinoma of the jaws (IOCJ). In parts 1 and 2, we discussed metastatic and salivary-type and odontogenic carcinomas, respectively. This part deals with primary intraosseous squamous cell carcinoma. Again, based on a critical approach, we emphasize histopathologic features, diagnostic difficulties, discuss hist...

Primary intraosseous mucoepidermoid carcinoma of the jawbones is an extremely rare malignant salivary gland tumour constituting 2-4.3% of all the reported mucoepidermoid carcinomas. We report a case of intraosseous mucoepidermoid carcinoma of the mandible in an 80-year old female patient developing from a previously diagnosed dentigerous cyst. An excisional biopsy was performed and the histopat...

Primary de novo intraosseous carcinoma (PIOC) is a rare and unique neoplastic lesion commonly occurring in the jaws. It is locally aggressive with very poor prognosis. Hereby we are presenting a case of proliferative growth from the non-healing extraction socket in a 45 year old female patient with eroded coronoid process and ramus of the mandible radiographically. (Lakshman AR, Kanneppady SK: ...

BACKGROUND Primary intraosseous squamous cell carcinoma is a rare jaw bone tumor defined as squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa and developing from residual odontogenic epithelium or from an odontogenic cyst or tumor. Solid type of this tumor arising in the maxilla is an even rarer presentation, because the majorities derive from cys...

Primary de novo intraosseous carcinoma of the jaws has been rarely reported. We present a new case of this unusual tumour and discuss its histopathological and clinical aspects. The subject was a 76-year-old man who was seen due to complaints of pain and the presence of gingival changes in the left mandible. A panoramic radiograph and computed tomography revealed a large mandibular radiolucency...

Introduction: Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare malignant lesion arising within the jawbones, without initial connection with the oral mucosa. This malignant lesion develops from odontogenic epithelium or odontogenic cysts or tumors. Case Report: In this case report, an intraosseous squamous cell carcinoma arising from an odontogenic cyst in a 60-year-old male pati...
