This monograph offers a comprehensive review of the wide variety of tumors that occur in the eyelid, conjunctiva, retina, uveal tract, lacrimal gland and sac, orbit, and optic nerve. Over the four decades since publication of the First Series fascicle on this subject considerable advances have been made concerning the pathology, immunohistochemistry, molecular biology and behavior of ophthalmic tumors. These are covered in detail. The more lengthy discussions concern the two most important intraocular tumors, retinoblastoma and uveal melanoma, but there is considerable attention given to those tumors that are particularly associated with this site. Among these are: the sebaceous tumors of the eyelid; the rare phakomatous choristoma of the lower eyelid, (which may be confused with an adenocarcinoma); the actinically related tumors of the conjunctiva, (keratoses, carcinomas and melanomas); the lymphomas, fibrous histiocytomas and childhood rhabdomyosarcomas of the orbit; and the melanocytoma of the optic nerve head. There are shorter discussions of extraocular tumors that have similar counterparts elsewhere in the body. The classification of tumors in this fascicle is based closely on the scheme proposed by the World Health Organization. Tables are presented that give frequencies of the various types of tumors based on the AFIP experience along with data from other registries and published series from around the world. With its 420 high-quality photographs this book should be an invaluable and indispensable source for pathologists and ophthalmologists.
