Squamous 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 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 chronic hypertrophic Lichen Planus: A case report
Association of lichen planus and cutaneous malignancies is rare. Reports of neoplastic changes are mostly related to buccal chronic erosive lichen planus. We report herein a 29-year-old man who developed squamous cell carcinoma on previous lesions of chronic hypertrophic lichen planus of lower legs. Careful follow up of patients with chronic lichen planus and biopsy sampling of uncommon lesions...
متن کاملGhost Cell Odontogenic Carcinoma Arising from Calcifying Cystic Odontogenic Tumor: A Case Report
Ghost cell odontogenic carcinoma (GCOC) is an exceptionally rare and malignant odontogenic tumor with aggressive growth characteristics. We describe a case of GCOC which was considerably derived from a previously resected calcifying cystic odontogenic tumor (CCOT). Cellular atypia, mitotic activity, Ki-67 labeling index and matrix metalloprotease-9 positive expression rate were all increased in...
