The presentation of interesting cases has a long tradition as an educational tool and contributes to
lifelong learning. Discussing the clinical course and management of individual patients enhances our
understanding of disease and provides a framework for learning about medical advances.
The New England Journal of Medicine publishes several case-based series including Case Records
of the Massachusetts General Hospital, Clinical Problem-Solving, and Clinical Practice, plus
our online Interactive Medical Cases. We have chosen the cases in this collection based on their clinical
relevance to primary care. We hope you find this collection engaging and instructive.
