The Orbit: Biopsy, Excision Biopsy and Exenteration Specimens
Orbital disease is encountered in three forms in surgical pathology — as a diagnostic biopsy, an excision biopsy and in an “exenteration” specimen. In general, the use of biopsy is restricted to tumours or orbital inflammatory processes (“pseudotumour”) which simulate neoplasia. An orbital exenteration is reserved for inflammatory and neoplastic diseases which involve the tissues extensively, usually when the eye is blind. For the uninitiated, the techniques required for dealing with an exenteration specimen are somewhat specialised and the topic is dealt with separately at the end of the chapter.
