In the light of increased awareness of the legal as well as clinical implications of misdiagnosis of pathological specimens, this book provides the trainee and practising histo- and cytopathologist with a comprehensive review of the potential pitfalls encountered in a number of key diagnostic areas (cervical screening, breast cancer screening, pigmented lesions of the skin, lymphoproliferative disease, disease of the gastrointestinal tract and disease of the genito-urinary system). Each chapter has been written by a recognised expert in the organ or organ system concerned and, with the aid of full colour histo- and cytopathological specimens throughout, outlines the most important diagnostic and differential diagnostic features and indicates not only where confident diagnosis can sometimes prove problematic, but also how best to avoid these potential pitfalls in the first instance.
