RESUMEN

INTRODUCTION: Keratocystic odontogenic tumors (KCOTs) are cystic tumours originating from the dental lamina of the maxilla and mandible that are lined with keratinized epithelium. While benign, they can be locally destructive and have a high recurrence rate despite treatment. Rarely, KCOTs may undergo malignant transformation into Primary Intraosseous Squamous Cell Carcinoma (PIOSCC). CASE REPORT: This study reports the clinical findings, radiological scans and histopathology of 2 patients with KCOTs that underwent malignant transformation into PIOSCC. DISCUSSION: A comprehensive literature review was performed to similar reports documenting the malignant transformation of KCOTs. The potential for KCOTs to undergo malignant change should prompt oral maxillofacial surgeons and otolaryngologists to exercise a high index of suspicion when treating these lesions. Patients persisting with unresolved disease after treatment should be investigated for malignant transformation. Detailed histopathological examination of KCOT specimens is recommended to detect small foci of SCC which may be present in the epithelium.

RESUMEN

OBJECTIVE: To compare the effectiveness of cyclosporine solution versus triamcinolone acetonide in orabase in the treatment of oral lichen planus (OLP) in reducing signs and symptoms. STUDY DESIGN: One hundred thirty-nine biopsy-proven OLP patients were randomly assigned to cyclosporine (68) or steroid (71) applied onto the target lesion and affected areas. Assessments were at weeks 0, 2, 4, 8 by clinical scoring and grid measurement of the target lesion (reticulation, erythema, ulceration). Patients ranked severity of pain and burning sensation using visual analog scales. RESULTS: Although clinical response, pain, burning sensation, area of reticulation, erythema, and ulceration at week 4 were all worse in patients receiving cyclosporine than in those receiving steroid, the differences were not statistically significant. Large patient-to-patient variability was evident over the observation period, with little evidence of marked changes in levels over time in both treatment groups. CONCLUSION: Topical cyclosporine appears no more effective than steroid in the treatment of oral lichen planus.
