Unusual Carcinomas, Including Squamous Variants

Abstract

This chapter includes nontraditional carcinomas including unusual but interesting squamous carcinoma variants and endocrine tumors. They do occur, although infrequently, so we must be aware of their presence and their appearances, especially in biopsies. The purpose of this chapter is to illustrate these rare cancers to give the reader some pictures with which to compare biopsies of carcinomas that do not look like either typical squamous cell carcinomas or typical adenocarcinomas.
