At Three Rivers Dermatology in Coraopolis, PA, serving patients throughout Pittsburgh and Sewickley, PA, we frequently evaluate cysts that cause discomfort, concern, or cosmetic frustration. While many cysts remain harmless, different types form for different reasons and require different approaches to treatment. Understanding what type of cyst you may have helps clarify when observation is appropriate and when professional care becomes necessary.
What Are Cysts and Why Do They Form?
Cysts are closed pockets of tissue that develop beneath the skin and contain fluid, keratin, or other material. Most cysts grow slowly and feel smooth or firm to the touch. Blocked hair follicles, trapped skin cells, physical trauma, and inflammation all contribute to cyst formation. Although cysts rarely pose serious health risks, some become painful, infected, or large enough to interfere with daily activities.
Common Types of Cysts We Treat
Several cyst types share similar appearances, but their origins and treatment options differ. The most common cysts we diagnose include:
- Epidermoid cysts, which form when skin cells move deeper into the skin instead of shedding naturally. These cysts often appear on the face, neck, or trunk and contain thick keratin material.
- Sebaceous cysts, which develop from oil glands and contain oily material. These cysts often grow slowly and may become inflamed if the gland ruptures.
- Pilar cysts, which usually form on the scalp and originate from hair follicles. These cysts often feel firm and rarely become infected.
- Inflamed or infected cysts, which can affect any cyst type and cause redness, tenderness, warmth, or drainage.
Each of these cysts requires careful evaluation to confirm the diagnosis and rule out other skin conditions.
How Treatment Varies by Cyst Type
Treatment for cysts depends on size, symptoms, location, and whether inflammation or infection exists. Some small, stable cysts require only monitoring. When cysts become painful, repeatedly inflamed, or cosmetically bothersome, we recommend treatment.
Epidermoid and sebaceous cysts often respond well to complete surgical removal, which prevents recurrence by eliminating the cyst wall. Inflamed cysts may first require medication to calm inflammation before removal. Pilar cysts typically undergo surgical excision, especially when they interfere with grooming or cause discomfort on the scalp. While treatments share similarities, such as local anesthesia and outpatient care, the timing and technique differ based on cyst behavior.
When to Seek Dermatologic Care
We recommend evaluation if cysts grow rapidly, become painful, drain, or change appearance. Attempting to squeeze or drain cysts at home often worsens inflammation and increases infection risk. Professional care ensures accurate diagnosis and proper management.
