A boil cyst isn't a medically recognized term. Boils and cysts are distinct conditions, though they can sometimes be confused. Let's clarify the differences:
Understanding Boils and Cysts
A boil, also known as a furuncle, is a painful, pus-filled infection of a hair follicle or oil gland. It typically appears as a red, swollen bump on the skin and often feels warm to the touch. The pus is a result of the body's immune response fighting the infection, usually caused by bacteria like Staphylococcus aureus.
A cyst, on the other hand, is a sac-like structure under the skin containing fluid or semi-solid material. Cysts are not inherently infected, although they can become infected and resemble a boil if they rupture or become inflamed. They often appear as painless lumps, but size and location can impact symptoms. The contents and causes of cysts are diverse, varying greatly depending on the type.
Key Differences Summarized:
| Feature | Boil | Cyst |
|---|---|---|
| Cause | Bacterial infection of hair follicle | Various; often unknown, developmental |
| Appearance | Red, swollen, pus-filled, painful | May vary; often painless lump, fluid-filled |
| Location | Typically on skin surface | Usually under the skin |
While both boils and cysts can present as lumps under or on the skin, their underlying causes and compositions are different. The term "boil cyst" is inaccurate and can lead to confusion in diagnosing the underlying condition.
