This book covers the full range of pathologic conditions encountered during childhood and youth, including tumors and tumor-like conditions of all organ systems, with direct links to developmental biology pathways and genetics. It provides a user-friendly road map to the main diagnostic criteria and combines an organ-related approach with an explanation of the diagnostic approaches to various specific diseases and syndromes, including sequential segmental analysis of congenital heart disease. More than 500 new full-color macro- and microphotographs using more than 500 multi-photographic panels are included to provide a realistic basis for comparison macroscopically and under the lens, and summarizing tables highlight key information in the concise form required for at-a-glance review. Pathologists will find the book very helpful when signing out complex and challenging cases, and it will also prove invaluable for exam preparation and continuing medical education.

In June 2021, new waves of the current COVID-19 pandemic are still messing up our lives and magnetizing the compass of our life. No other epidemics or pandemics have been politicized at such a level since ancient times. The full political spectrum from right to left has tried to ride this pandemic and upset the public health response efforts. Statistics and politics have changed our daily approach to this brutal infection, but even crueler has been the palpable miscommunication. Massive and uncontrolled lockdowns and not climate change are destroying the economy of our planet. Intolerance against vaccine opponents and hesitant families has been vocalized with martial tones in both social media and news channels. In this book, the author analyzes the pandemic in a historical context, emphasizes the importance of facemasks, but also highlights our human approach to anti-mask psychology. It would be appalling to call mistakes in public health decisions "learned lessons" because it reduces the gravity of the consequences of inadequate communication. Our youth is our future. The mental issues arising from a lack of social interaction and in-person education are dreadful. Vaccines are powerful and represent the most outstanding progress in medicine. There is light at the end of the tunnel, but vaccine acceptance or herd immunity is not the answer, or probably, not the only one. There is true hope that we are going back to our world, but the COVID-19 pandemic may be an occasion to reconsider the traditional family in the center of our lives and daily politics. A tolerance towards any race needs to be contagious, militant, and blazing to vehemently rebuild and revitalize the American Dream.
