This new guide on Cutaneous Metastases is crafted for healthcare professionals and offers in-depth examination of the development, diagnosis, treatment, prognosis, and survival dynamics surrounding cutaneous metastases, providing a holistic perspective on these dermatological challenges. Ensuring an encompassing approach, the book expands on the diverse landscape of primary tumors, and their dermatological implications. The introduction defines cutaneous metastases, exploring epidemiology, and the underlying pathogenesis. Dedicated chapters follow, that focus on cutaneous metastases from gynecological cancers, providing detailed insights into ovarian, cervical, and endometrial cancers. Metastases originating from gastrointestinal cancers, including liver, colorectal and pancreatic cancers, are then taken into exam, as well as those deriving from lung cancer and breast cancer (invasive ductal and invasive lobular carcinoma). Following chapters deal with other primary tumors, including prostate, kidney, and thyroid cancers. Understanding the histopathological features of cutaneous metastases is crucial; to this end, the book covers classification to immunohistochemical profiling and molecular clonal analysis, all essential for accurate diagnosis. A dedicated section outlines the various treatment options, prognosis considerations, and follow-up protocols for cutaneous metastases. Real-world cases provide clinical insights and bridge theory with practice. The book concludes with a comprehensive summary of key points and outlines future directions for research on cutaneous metastases. With its clear tone and multidisciplinary perspective on dermatological challenges posed by metastatic manifestations, this work will be a valued companion to healthcare professionals, including dermatologists, oncologists, and other specialists involved in the care of cancer patients.
