This book should provide the trainee or practising histo- or cytopathologist with a comprehensive review of the potential pitfalls encountered in a number of key diagnostic areas (cervical screening cytology, breast cancer/screening cytology and histology, pigmented lesions of the skin, such as melanoma, lymphoproliferative disease, the gastrointestinal tract and the genito-urinary system). Each chapter has been written by an authority in the field and, with the aid of full colour histo- and cytopathological specimens, outlines the most important diagnostic and differential diagnostic features in each area and also highlights where confident diagnosis can sometimes prove problematic, as has been highlighted by a number of high-profile cases in the UK.
