This Atlas gives the complete expert opinion on the diagnostic features of eyelid and conjunctival tumors (benign and malignant): a state-of-the-art guide with numerous images, useful for both dermatologists and ophthalmologists. This invaluable resource, illustrating clinical, histological and re fectance confocal microscopy features, first addresses the normal conditions of the ocular surface, then reviews lesions due to epidermal, melanocytic and adnexal tumors. A final part is devoted to conjunctiva conditions, from normal to malignant conjunctival tumors. The high number of illustrations and their description of many ocular surface lesions with in vivo confocal microscopy make this atlas an essential guide for the practitioners of both specialities.
