Oral lesions are conventionally diagnosed using white light endoscopy and histopathology. This can pose a challenge because the lesions may be difficult to visualise under white light illumination. Confocal laser endomicroscopy can be used for confocal fluorescence imaging of surface and subsurface cellular and tissue structures. To move toward real-time "virtual" biopsy of oral lesions, we int...

IMPORTANCE Conjunctival papilloma is a benign epithelial tumor occurring in both children and adults with varying clinical features and outcomes. In this article, we describe our experience regarding the difference in the clinical features and outcomes of conjunctival papilloma based on age at initial examination. OBJECTIVE To evaluate the clinical features, treatment, and outcomes in patient...
We present a well-documented case of biopsy-proven renal malacoplakia with an excellent response to oral fluoroquinolone therapy.
BACKGROUND Oral malignant tumors in Thailand have not been extensively studied. Hence the following study was conducted. AIMS To determine the prevalence and clinicopathologic data of the oral malignant tumors from Thailand. SUBJECTS AND METHODS Biopsy records of the Oral Pathology Department, Chulalongkorn University; Department of Oral Biology and Diagnostic Sciences, Chiang Mai Universit...
BACKGROUND Human papillomavirus (HPV), the causal agent of cervical cancer, appears to be involved in the etiology of cancer of the oral cavity and oropharynx. To investigate these associations, we conducted a multicenter case-control study of cancer of the oral cavity and oropharynx in nine countries. METHODS We recruited 1670 case patients (1415 with cancer of the oral cavity and 255 with c...
