The role of in vivo confocal microscopy in the diagnosis of eyelid margin tumors: 47 cases

BACKGROUND: Handheld in vivo reflectance confocal microscopy (IVCM) is a new imaging method that allows noninvasive diagnosis of cutaneous tumors but to date it has not been used in the study of eyelid tumors. OBJECTIVE: We sought to evaluate the suitability of IVCM for eyelid margin tumors. METHODS: We prospectively evaluated the IVCM features of 47 eyelid margin lesions, clinically suspicious of malignancy; 35 of these were excised whereas the other 12, with no IVCM malignant features, were followed up for at least 1 year. Clinical, IVCM, and histologic diagnoses were compared. RESULTS: IVCM showed sensitivity and specificity of 100% and 69.2%, respectively, for malignancy (basal cell carcinoma, squamous cell carcinoma, and melanoma). The follow-up of the 12 nonexcised lesions did not show any clinical progression. LIMITATIONS: The lesions showing neither clinical nor IVCM features for malignancies were not biopsied in view of the potential functional and aesthetic consequences of eyelid margin surgery. CONCLUSION: Used with a handheld dermatology-specific microscope, IVCM can play a role in the noninvasive diagnosis of eyelid margin lesions. Further studies are needed to better define diagnostic criteria of eyelid tumors and improve the specificity of this technique

Handheld reflectance confocal microscopy for the diagnosis of conjunctival tumors

PURPOSE: To evaluate whether the handheld in vivo reflectance confocal microscopy that has been recently developed for the study of skin tumors is suitable for the diagnosis of conjunctival tumors. DESIGN: Prospective study, observational case series. METHODS: We prospectively evaluated the reflectance confocal microscopy features of 53 conjunctival lesions clinically suspicious for tumors of 46 patients referred to the University Hospital of Saint-Etienne (France) by using the handheld device. Twenty-three lesions were excised (3 nevi, 10 melanomas, 5 squamous cell carcinoma, 2 lymphomas, and 3 pinguecula/pterygium) while the other 30, presenting no reflectance confocal microscopy malignant features, were under follow-up for at least 1 year. Clinical reflectance confocal microscopy and histologic diagnosis were compared. RESULTS: In vivo reflectance confocal microscopy diagnosis was in agreement with the histologic diagnosis in all cases and none of the lesions that were not excised show any clinical progression under follow-up. CONCLUSION: In vivo reflectance confocal microscopy with a handheld dermatology-dedicated microscope can play a role in the noninvasive diagnosis of conjunctival lesions. Further studies should be performed to better define the diagnostic ability of this technique
