This handbook is designed to serve as a compact, up-to-date, and easy-to-use reference on the clinical features and pathology of ocular tumors. It comprises approximately 75 entries that cover the full spectrum of clinically encountered ocular tumors as well as tumor classification and other selected topics. Each entry addressing a given tumor or class of tumors is organized in a standard way, with information on synonyms, definition, etiology, clinical presentation, diagnosis, differential diagnosis, prophylaxis, therapy, prognosis, and epidemiology. Key references are also provided. The book has the advantage of having been written by members of an ocular oncology group from a leading cancer center, and will be of great practical value for ophthalmologists and ophthalmic pathologists.
