Primary intraosseous squamous cell carcinoma arising from keratocystic odontogenic tumor.
Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare lesion that almost exclusively occurs in the jaws. Most PIOSCCs originate from epithelial lining of odontogenic cysts, especially from radicular, residual, and dentigerous cysts. A few cases have been shown to arise from keratocystic odontogenic tumors (KCOTs). This is a report of a case of PIOSCC that arose from an untreated kerat...
متن کاملSquamous cell carcinoma arising from keratocystic odontogenic tumor
Squamous cell carcinoma (SCC) arising from epithelial lining of Keratocystic Odonogenic Tumour(KCOT) is very rare with 0.001‐0.002 incidence.[1] Keratin metaplasia leading to epithelial hyperplasia and dysplasia can be one of the mechanisms of malignant changes so, presence of keratinisation in the cyst lining increases the risk of malignancy.[2,3] According to the new histological classificati...
متن کاملSquamous cell carcinoma arising from a keratocystic odontogenic tumor: a case report
BACKGROUND The term "primary intraosseous squamous cell carcinoma" was introduced in 2005 by the World Health Organization with three subcategories. Squamous cell carcinoma arising from the lining of an odontogenic cyst is one important rare subcategory of such lesions with an incidence of 0.01 to 0.02%. Furthermore, the appearance of such malignancy in an odontogenic tumor such as keratocystic...
متن کاملPrimary intraosseous squamous cell carcinoma arising from an odontogenic keratocyst: a case report and literature review
Primary intraosseous squamous cell carcinoma (PIOSCC) derived from an odontogenic keratocyst (OKC) is a rare malignant neoplasm of the jaws, which is locally aggressive with quite poor prognosis. The incidence of carcinomas arising in odontogenic cysts was reported to be approximately 1-2/1000. The number of well-documented cases of PIOSCC ex OKC is extremely small; hence, no sufficient inciden...
متن کاملPrimary intraosseous odontogenic squamous cell carcinoma of the mandible
Primary intraosseous odontogenic squamous cell carcinoma (PIOSCC) is a rare tumor. The incidence is low, and approximately 200 cases are reported in literature. The etiology is associated with the malignant degeneration of embryological remains. Differential diagnosis includes alveolar carcinomas, jaw metastases from other locations, odontogenic tumors, and tumors of the maxillary sinus. Howeve...
