When HS lesions on the buttocks heal, they can leave behind marks, discoloration, and scarring. The "rectangular marks" you're noticing are likely a form of scarring or skin changes that happen as lesions drain and heal over time.
HS lesions on the buttocks can go through several stages:
- Painful lumps or nodules that persist for weeks or months
- Abscesses that fill with pus and may burst, releasing fluid
- Sinus tracts (tunnels) that form under the skin connecting lesions
- Scarring and skin darkening as the area heals
One myHSteam member described their experience: "I have multiple painful boils and tunnels under the skin. My skin has darkened, and I have a burning sensation." The rectangular or linear marks are often the result of sinus tracts healing close to the skin's surface, or scarring from repeated flare-ups in the same area.
It's worth discussing these marks with a dermatologist, as tracking how lesions look and change over time helps them assess your HS stage and adjust your treatment plan accordingly.
