Toluidine Blue 0.05% Vital Staining for the Diagnosis of Ocular Surface Squamous Neoplasia in Kenya.
IMPORTANCE Clinical features are unreliable for distinguishing ocular surface squamous neoplasia (OSSN) from benign conjunctival lesions. OBJECTIVE To evaluate the adverse effects, accuracy, and interobserver variation of toluidine blue 0.05% vital staining in distinguishing OSSN, confirmed by histopathology, from other conjunctival lesions. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional...

Although there has been concensus that staining often assists in the identification of these lesions, results have been diverse. In most studies false negative were not recorded as biopsies of lesions that did not retain to...
متن کاملThe Expression of P53 in Leukoplakia, Squamous Cell Carcinoma and Normal Oral Epithelium Using Immunohistochemical Staining Method
Background & Aims: Leukoplakia is the most common premalignant or potentially malignant lesion of the oral mucosa and its potentiality for malignant transformation is unpredictable. The aim of the present study was to evaluate p53 expression in normal oral epithelium, leukoplakia and oral squamous cell carcinoma. Methods: The standard Biotin streptavaidin peroxidase immunohistochemical staining...
