Pathology Casebook: Microscopy to Molecular Correlations in Disease Diagnosis MTA
An illustrated collection of real pathology cases linking histology, immunohistochemistry, and molecular findings to clinical problems

About this book:

This book serves as a comprehensive casebook for modern pathology, bridging the gap between traditional microscopic diagnosis and the contemporary molecular landscape. Each chapter follows a real-world clinical scenario—ranging from solitary pulmonary nodules and palpable breast masses to complex bone lesions and acute leukemias—to illustrate a step-by-step diagnostic reasoning process. By integrating histology, immunohistochemistry, and advanced molecular testing such as next-generation sequencing and FISH, the text demonstrates how pathologists arrive at unified, standards-aligned diagnoses that directly inform personalized patient management.

The text emphasizes the shift from purely descriptive morphology to a multi-modal approach where genetic signatures, such as *EGFR* mutations in lung cancer or *IDH* status in gliomas, serve as essential biomarkers for prognosis and targeted therapy. It highlights the critical role of the pathologist in "tissue stewardship," ensuring that small biopsy samples are used judiciously to yield maximal diagnostic and predictive information. Beyond initial diagnosis, the book explores the future of oncology through topics like liquid biopsies and the detection of minimal residual disease using circulating tumor DNA, which allows for ultra-sensitive monitoring of treatment response.

Designed for practitioners, trainees, and clinicians, the book underscores the necessity of multidisciplinary collaboration in the era of precision medicine. Every case concludes with a focus on clinical implications, showing how specific pathological findings dictate surgical choices, immunotherapy, and long-term surveillance strategies. Ultimately, the work cultivates a disciplined "habit of mind" for interpreting complex diagnostic data, ensuring that the transition from microscopy to molecules results in clearer answers and improved outcomes for patients.

What You'll Find Inside:

• Integrates histology, immunohistochemistry, and molecular testing to reach precise diagnoses across diverse organ systems.
• Each chapter presents a real-world case, walking through clinical vignette, microscopic findings, ancillary workup, and therapeutic implications.
• Highlights focused ancillary panels (special stains, IHC, FISH, PCR, NGS) and the importance of tissue stewardship for small samples.
• Correlates molecular alterations (mutations, fusions, copy-number changes) with morphology to inform prognosis and targeted therapy decisions.
• Emphasizes multidisciplinary collaboration, reporting language, and reflex testing pathways that directly impact patient management.

Who's It For:

This book is designed for practicing pathologists seeking refreshers on integrated diagnostics, pathology trainees learning to correlate morphology with molecular results, and clinicians (oncologists, surgeons, physicians) who want a deeper understanding of how pathology reports guide treatment decisions. It also serves as a teaching resource for tumor boards and multidisciplinary teams.
