Thanks for this answer. A couple of years ago I had one of these cysts at the middle of my upper back - where I couldn't reach. It opened and drained on Christmas Eve 😒 and it took me almost 8 months to close the wound, including getting wound care at the hospital twice a week. It was super deep and had lots of tunneling. Its all scar tissue now and still bothers me sometimes!!

Yes, sebaceous cysts can absolutely occur independently of HS. They form in sebaceous (oil) glands and can appear almost anywhere on the body, including the face, neck, back, chest, and genitals. Here are the main differences between a standalone sebaceous cyst and HS-related lesions:

Yes, sebaceous cysts can absolutely occur independently of HS. They form in sebaceous (oil) glands and can appear almost anywhere on the body, including the face, neck, back, chest, and genitals. Here are the main differences between a standalone sebaceous cyst and HS-related lesions:

- Cause: Sebaceous cysts form in oil glands, while HS develops in hair follicles and sweat glands
- Location: Sebaceous cysts can appear almost anywhere, while HS tends to occur where skin rubs together — armpits, groin, inner thighs, and buttocks
- Tunneling: HS lesions can form tunnels under the skin over time, which sebaceous cysts typically do not
- Recurrence & spread: HS lesions tend to return and spread to multiple areas, while a standalone sebaceous cyst is usually isolated
- Infection risk: Both can become infected and painful, but HS carries a higher ongoing risk due to its chronic, recurring nature

A key thing to keep in mind is that only a dermatologist can properly tell the difference. If you're noticing recurring lumps, spreading symptoms, or worsening pain, it's worth getting checked out sooner rather than later.
