Section Summary

Tunnels are not required for moderate HS.
Hurley staging describes structural disease but may underestimate active inflammation.
IHS4 measures inflammatory activity; scores of 4–10 indicate moderate inflammatory disease.
Patient history and patient-reported burden are essential to interpreting lesion counts.
Outcome measures organize clinical information, but no single measure captures the complete severity of HS.

Key Takeaway: Moderate HS is multidimensional. Evaluate inflammatory activity, structural damage, and patient-reported burden together rather than relying on any single examination finding or severity measure.
