Keratocystic Odontogenic Tumour

Introduction. Keratocystic odontogenic tumours raise particular interest, because of their high recurrence rate and association with nevoid basal cell carcinoma syndrome. Objective. To analyze the clinical and histopathological features of all cases diagnosed as keratocystic odontogenic tumour in a Brazilian population. Methods. A total of 64 keratocystic odontogenic tumours, arising in forty-six patients, were evaluated using the following parameters: association with nevoid basal cell carcinoma syndrome, gender, age at first diagnosis, race, anatomical location, symptoms, radiographic features, history of recurrence, association with teeth, and treatment. Results. Keratocystic odontogenic tumours were more frequent among women than men (1:0.84). The mean patient age was 31.5 years (SD: ?16.6). Ten tumours (16.4%) involved the maxilla and 51 (83.6%) the mandible. Swelling (n=12; 46.1%), followed by pain and swelling (n=4; 15.3%), were most common clinical manifestations. A unilocular radiotransparency with well-defined margins was the main radiographic finding (n=29; 87.8%). A significant association was observed between the multilocular radiographic pattern and recurrence (p<0.05, Fisher?s Test). Sixty-one (95.3%) tumours were treated by surgical enucleation followed by bone curettage, and the recurrence rate was 13% (n=6). This study showed that the keratocystic odontogenic tumours relapsed within a mean period of 25-36 months. Conclusion. Despite the results of this study being similar to previous reports found in the literature, it provides an important insight about keratocystic odontogenic tumours in a Brazilian population.

Background. We report a case of multiple keratocysts first diagnosed in an 8-year-old boy. Case report. The incidental radiographic finding of a cystic lesion in an 8-year-old boy led to the surgical enucleation and further diagnosis of a keratocyst associated with a tooth crown. In the course of dental maturation from deciduous to permanent teeth, the boy presented new lesions, always associated with the crowns of teeth. Gorlin-Goltz (nevoid basal-cell carcinoma) syndrome was suspected, and the genetic analysis detected a previously undescribed germline variant in the PTCH1 gene. Treatment. This included a surgical removal of the cystic lesions, as well as the affected teeth. Follow-up. Due to the high recurrence rate of the keratocysts, frequent radiological checks were performed over a 5-year period.

Significant Difference

SummaryA study of sixty patients with basal cell carcinoma of the head and neck region carried out over a six-year period (1979–1985) is hereby presented. Sixteen (26.72 percent) were albinos and 44 (73.28 per cent) negroids. Forty-eight (80 per cent) were outdoor workers. The negroid patients presented between the 3rd and 4th decades while the albinos presented a decade earlier. The commonest site involved in the head and neck was the forehead. The midface showed the highest recurrence rate in both groups, even after adequate excision. The frequency of recurrence in tumours presenting with a size of 2–5 cm. diameter was significantly higher in the albinos than in the negroid (P<0.05), whereas, with tumours of a size larger than 5 cm., there was no statistically significant difference between the albino and the negroid. However, the overall recurrence rate was significantly higher in the albinos (P<0.005). The mortality among the albinos was 25 per cent while there were no deaths in the negroid Africans.

Background. Basal cell carcinoma (BCC) is the most common malignancy of the eyelids. Medial canthal BCCs tends to recur more often. Purpose. To evaluate the clinical and histological features of primary and recurrent periocular BCC, in order to identify any existing associations. Methods. Data from 87 patients (71 primary and 16 recurrent) were analyzed in this study. All patients underwent tumor excision with frozen section margin control at the Goldschleger Eye Institute between 1/1995 to 12/1997. Statistical analysis was performed to identify possible associations between histological and clinical characteristics of primary and recurrent BCC. Main Outcome Measures. Anatomical location, clinical presentation, and histology of peri-ocular BCC. Results. No association was found between histopathological and clinical characteristics of BCC. Similar features with regard to eyelid location and histology were found in primary and recurrent peri-ocular BCCs, whereas recurrent BCCs tended to involve a greater eyelid extent with a longer duration of symptoms. Medial canthal BCCs, morpheaform, or sclerosing histology were not more common in the recurrent BCC group. Conclusions. Similar clinical and histological characteristics were noted in primary and recurrent periocular BCC, implying that incomplete surgical excision rather than anatomical location or histological features is the main cause for recurrence.

Background: It is unknown whether the histologic subtypes of basal cell carcinoma (BCC) arise from a common progenitor cell or whether other factors play a role in their development. Objective: To investigate the relationship between the different BCC histopathologic subtypes and anatomical distribution of BCCs in a Canadian dermatology practice. Methods: The charts of all patients diagnosed with BCC between 1993 and 2005 from a single private dermatology practice in Vancouver, Canada, were reviewed. Descriptive data analysis was undertaken to look at the distribution of histologic subtypes based on age, gender, and anatomical location. Results: Nodular BCCs accounted for 58% of all tumors. Sixty-six percent of these were situated on the head/neck (odds ratio [OR] = 3.0, 95% confidence interval [CI] = 2.1-4.3, P < .0001). Infiltrative (OR = 2.4, 95% CI = 1.5-4.1, P = .0003) and superficial BCCs were more common in women (OR = 3.7, 95% CI = 2.5-5.7, P < .0001), affected the trunk (OR = 3.2, 95% CI = 2.1-4.9, P < .0001), and appeared in younger individuals (OR = 1.8, 95% CI = 1.2-2.7, P = .004). Conclusion: Our results show a preference of distinct BCC subtypes for certain anatomical locations.
