Diagram description
Four steps connect phenotype, sampling, differential diagnoses and synthesis. No microscopic tissue is artificially reconstructed.
Reasoning
An isolated serum IgG4 or immunostain result is insufficient to establish the diagnosis.
Clinical comparison
Interpret the findings together and investigate competing explanations when data do not agree.
Pitfalls and limits
This is a conceptual educational aid, not an authentic examination, a complete diagnostic rule or an individual prescription. See the cited sources and full French statement of limitations.
Take-home message
An isolated serum IgG4 or immunostain result is insufficient to establish the diagnosis.
