Cracking the Code: Understanding HS Vocabulary

Navigating the world of Hidradenitis Suppurativa (HS) can feel like learning a new language. With terms like abscesses, cysts, and boils being thrown around, it’s easy to get lost in translation. But here’s the deal: using the right vocabulary isn’t just about semantics—it’s a vital step toward accurate diagnosis and effective communication. Let’s break it all down and better understand the HS vocabulary.


HS Vocab Graphic

Why Language Matters

Getting specific with how we describe HS symptoms does more than just make us sound informed. Accurate terms ensure healthcare providers understand the severity of the condition, avoiding the all-too-common risk of downplaying HS as “just boils” or “a few cysts.” Mislabeling these lesions can delay proper treatment and keep you stuck in a cycle of frustration.


Recommended Terms 

  • Boil-like abscesses

  • Lesions

  • Nodules

  • Pustules


What to Avoid

  • Boils

  • Cysts


Understanding the HS Vocabulary Breakdown

Here’s your quick-reference guide to understanding the nuances of HS-related terminology:


Deformation of Affected Areas

The repeated inflammation-healing cycle in HS leaves its mark—literally. This can include:

  • Tunneling (Sinus Tracts): Painful channels under the skin that connect abscesses or inflamed areas, contributing to HS’s chronic nature.

  • Scarring: Thick, fibrous tissue develops over time, leading to significant deformation and even reduced mobility.


Cysts

Cysts are not interchangable with HS abscesses, though HS sufferers may develop them. Here’s what makes cysts unique:

  • Enclosed in a sac made of abnormal (but typically benign) cells.

  • Filled with fluid, pus, or a foul-smelling substance.

  • Often painless and non-infectious unless inflamed or infected.

  • Can linger for years without causing trouble but may require surgical removal if complications arise.


Abscesses

Abscesses are a different beast altogether, especially in the context of HS:

  • Larger, deeper, and more painful than boils.

  • No sac; typically filled with pus, fluid, or blood.

  • Can appear suddenly, linger for extended periods, or recur.

  • May form independently or when a cyst becomes infected.


Lesions, Nodules, Pustules, and Folliculitis

  • Lesion: General term for an abnormal area of skin caused by HS.

  • Nodules: Lumps under the skin that may or may not drain.

  • Pustules: Small bumps filled with pus, often mistaken for pimples.

  • Folliculitis: Inflammation or infection of a hair follicle, appearing as red or white “pimple-like” sores.


Spot the Difference: Cysts vs. HS

While cysts can cause discomfort, they don’t typically pack the same punch as HS in terms of chronic pain, scarring, and systemic involvement. Remember: not every skin irritation is HS-related. It’s important to identify what’s actually going on.


Common Skin Cysts

Here’s a list of common cyst types to help you understand the differences (but always consult a professional for diagnosis):

  • Epidermoid cyst

  • Sebaceous cyst

  • Bartholin’s cyst

  • Ganglion cyst

  • Pilonidal cyst

  • Cystic acne

  • Ingrown hair cyst

  • Pilar cyst

  • Mucous cyst

  • Chalazia cyst


Why Misdiagnosis Happens

HS often gets mistaken for acne, folliculitis, boils, or cysts—especially by those unfamiliar with the condition. Misdiagnosis is frustratingly common. If you’re unsure about your diagnosis, trust your instincts, do your research, and don’t hesitate to seek a second opinion.


Let’s take back control of the conversation around HS by using the right terms. Words matter—especially when they lead to better care and understanding.
