Need to reclassify keratocystic odontogenic tumor into cyst and neoplasm
نویسنده
چکیده
Sir, Odontogenic keratocyst (OKC) is known for its pathognomonic features, i.e., aggressiveness and high rates of recurrence, which has been of interest and debate since the first description of this entity by Philipsen in 1956.[1] Recently, the World Health Organization (WHO) working group on odontogenic tumors recommended the term “Keratocystic Odontogenic Tumors” (KCOT) for these lesions to address their neoplastic nature, which indicated that the OKC epithelial lining may have some intrinsic growth potential,[2] but reclassification has not yet been universally accepted and there is no any worldwide agreement regarding treatment of this controversial entity.

Angiogenesis: A Critical Role in Locally Aggressive Behavior of Keratocystic Odontogenic Tumor
Introduction: Odontogenic cysts are osteodestructive lesions affecting the jaws. Odontogenic keratocyst is an odontogenic cyst with highly aggressive features. Multicystic ameloblastoma is a benign epithelial odontogenic tumor with more aggressive behavior than dentigerous cyst and odontogenic keratocyst. Invasion and metastasis of tumors require increased blood vessels during tumorigenesis. Th...

Keratocystic odontogenic tumor (KCOT) is a benign intraosseous neoplasm of the jaw occurring most commonly in mandibular ramus molar area with male predilection. Peripheral KCOTs are very uncommon. Here we report a case of keratocyst in buccal mucosa in a 55 years old female patient, the diagnosis of which was based on subjective histological evaluation and further confirmed by immunohistochemi...

AIM The aim of this report is to introduce a rare case in which an infected keratocystic odontogenic tumor (KCOT) was initially diagnosed and treated as a dentoalveolar abscess. BACKGROUND Keratocystic odontogenic tumor (KCOT) is a benign neoplasm that can be secondarily infected. However, cervical soft tissue abscess formation as a result of an infected odontogenic cyst or tumor is a rare co...

Calcifying odontogenic cyst (COC) is a unique odontogenic lesion with combined features of a cyst and neoplasm. This lesion shows a great diversity in its clinicopathological behavior. It may become aggressive and rarely malignant. This case is an aggressive COC of the maxilla in a young male patient which recurred after several radical surgical excisions. Eventually invading the cranium, t...
