“…Keratocystic odontogenic tumor was the third most common lesion in this group (7.0%), which was compatible with the study of Jones & Franklin [6]; however, this lesion was the most frequent in the study of Koivisto et al [22]. Moreover, most keratocystic odontogenic tumors were located in the mandible in this study cohort, similar to the results of the other studies [18,19,21,22]. …”

IntroductionA study of the whole spectrum of biopsied head and neck (HN) diseases in Taiwan has not yet been performed. Therefore, the current study aimed to provide updated information about HN lesions in a cohort of referral Taiwanese patients for histopathological examination.MethodsHN lesions (2000–2011) in patients with records of age, sex, and histological diagnoses were retrieved from the Oral Pathology Department of the institution. These lesions were classified into four main categories: tumor/tumor-like reactive lesions, cystic/pseudocystic lesions, inflammatory/infective lesions, and others/miscellaneous lesions.ResultsA total of 37,210 HN lesions were included in the current study. Most of these lesions were distributed in the group of tumor/tumor-like reactive lesions, followed by the groups of inflammatory/infective lesions, cystic/pseudocystic lesions, and others/miscellaneous lesions. Squamous cell carcinoma was the most common HN lesion, and was also the most frequent malignant lesion among the referral patients.ConclusionIt was worthy of note that squamous cell carcinoma and oral potentially malignant disorders comprised high percentages of all HN lesions for the present cohort of referral patients.

The aim of this study was to investigate the histopathological features of radicular cysts (RCs) diagnosed in a Brazilian population. Seventy-three cases of RCs, from a total of 1480 biopsies diagnosed between 2001 and 2008 at the Laboratory of Oral Surgical Pathology of the Dental School of the Federal University of Bahia were investigated regarding their histopathological features. Morphological results showed that exocytosis (n=50), spongiosis (n=40), acanthosis (n=28), atrophic epithelium (n=27) and apoptotic bodies (n=21) were the most common findings. Other morphological findings included: foamy macrophages (n=10), Russell's bodies (n=7), cholesterol crystals (n=7) and glandular-like odontogenic epithelial rests (n=1). Evidence of exogenous material was seen in 16 samples. It was concluded that the clinical and histopathological findings observed in Brazilian patients were comparable with those described for other populations.

“…In the study of Habibi et al in 2007 15 in which 83 cases of OKC were retrospectively reviewed over 10 years, 67.5% of lesions were in mandible and 32.5% were in maxilla. In the study of Sharifian et al in 2011 16 , dentigerous cyst showed a higher tendency to maxilla. In our study, well-corticated margin was the most common external border in both dentigerous cyst and OKC.…”

Objectives: Pericoronal radiolucencies are common pathologic findings in regular dental checkups. Since dentigerous cyst is the most common pathologic pericoronal radiolucency and as odontogenic keratocyst (OKC) is a common cyst also and an aggressive lesion with high recurrence, radiographic features of these lesions were discussed in this study using panoramic radiography and cone beam computed tomography. Materials and Methods: In this cross-sectional case series study, radiographs from 56 patients who were referred to a private maxillofacial radiology center or dentistry faculty in Mashhad/Iran from 2008 to 2013 in which radiolucent pericoronal lesion was observed in jaws with histopathologic results of dentigerous cyst or OKC were separately examined by two maxillofacial radiologists. Both observers were unaware of pathology results. Lesions were assessed based on their location, periphery, and impaction on the surrounding structures. Then, obtained data were analyzed using descriptive tables. Results: 56 lesions were identified in 56 patients. There were 20 odontogenic keratocyst and 36 dentigerous cysts. The majority of dentigerous cysts and OKCs occurred in the posterior mandible and showed a well corticated border. External root resorption was higher in OKC cases. In addition, displacement tendency of surrounding structures (other than tooth) such as nasal floor, mandibular canal, buccal and lingual cortex (in the form of expansion) as well as destruction of cortex, nasal floor or sinus walls was higher in OKC than in dentigerous cyst. Conclusion: Except of tooth displacement other parameters related to the effect on surrounding structures in this study showed higher frequency in OKC than dentigerous cyst.
