Clinical presentation and differential diagnosis of nasolabial cyst.
(1/7)
Nasolabial cyst is a rare non-odontogenic, soft-tissue, developmental cyst occurring inferior to the nasal alar region. The patient usually presents with a slowly enlarging asymptomatic swelling, typically without radiographic abnormalities. This paper documents the presentation and management of a 46-year-old woman with a nasolabial cyst. The histopathologic features, differential diagnosis, treatment and prognosis are discussed.

Prevalence and distribution of odontogenic cysts in Sicily: 1986-2005.
(3/7)
The objective of this study was to assess the prevalence of odontogenic cysts (OCs) in Sicily and evaluate their distribution during a 20-year period. A cross-sectional retrospective study was carried out in 1,310 cysts of the jaw diagnosed in 12,197 individuals, who consecutively attended the Odontostomatologic Clinic of Palermo from 1986 to 2005. 1,273 cysts were classified as odontogenic, whereas only 37 were non-odontogenic. In the former group, the most frequent lesions were radicular cysts (84.5%), followed by dentigerous OCs (11.4%). Inflammatory radicular cysts were observed more in male gender, younger age at diagnosis and anterior maxilla as site of presentation. Unlike dentigerous cysts, the frequency of radicular cysts decreased from 10.4% in 1986-1995 to about 8% in 1996-2005 (P < 0.0001). Inflammatory radicular cysts are the most represented group among OCs in our area with a higher prevalence than that reported in other countries. The decreasing epidemiologic trend with time could be attributed to the possible changes in individual oral health behavior. (+info)
Prevalence and distribution of odontogenic and nonodontogenic cysts in a Turkish population.
(6/7)
OBJECTIVE: To determine the relative frequency and distribution of odontogenic and nonodontogenic cysts in a large Turkish population. STUDY DESIGN: A retrospective survey of jaw cysts was undertaken at the Oral Diagnosis and Radiology and Oral and Maxillofacial Surgery Department, Ondokuz Mayis University Dental School, Samsun, Turkey. Data were retrieved from clinical files, imaging, and histopathology reports from 2000 to 2008; a total of 12,350 patients were included. In each case, we analyzed age, gender, type and number of cysts, and cyst location. Imaging patterns and pathologies associated with cystic lesions were also determined. RESULTS: The prevalence of odontogenic and nonodontogenic cysts was 3.51%; males were affected more frequently than females. There were 452 odontogenic cysts (98.5%) and seven nonodontogenic cysts (1.5%). The most frequent odontogenic cyst was radicular (54.7%), followed by dentigerous (26.6%), residual (13.7%), odontogenic keratocyst (3.3%), and lateral periodontal cyst (0.2%). Nasopalatine duct cyst (1.5%) was the only nonodontogenic cyst. By age, cysts peaked in the third decade (24.2%). Concerning location, no statistically significant difference was found between the maxilla and mandible (p>0.05). The most frequent radiological feature of these lesions was unilocular cyst (93.7%). Pathologies associated with cystic lesions occurred in 14.7%. CONCLUSION: The prevalence of both odontogenic and nonodontogenic cysts were lower than that reported in many other studies. In our study population, cysts were mainly inflammatory in origin. (+info)
