Original Author & Source Work
This interactive algorithmic tool is based on the foundational pattern-analysis tables and flowcharts (Pages 1–11) created by A. Bernard Ackerman, M.D. (1936–2008) in his landmark textbook:
“Histologic Diagnosis of Inflammatory Skin Diseases: A Method by Pattern Analysis” / “An Algorithmic Method Based on Pattern Analysis”
Educational & Clinical Disclaimer
This web application is an independent interactive digital adaptation designed for educational reference, dermatopathology study, and rapid algorithmic pattern navigation by pathologists, dermatologists, residents, and medical trainees.
Histopathologic criteria in inflammatory skin diseases frequently overlap and evolve over the lifespan of a lesion. This resource does not constitute medical advice and should never substitute for direct microscopic examination, specialized ancillary studies, or definitive clinicopathologic correlation.
