Pyogenic granuloma

April 11, 2025

  

A pyogenic granuloma is a common, benign skin growth that appears suddenly and tends to bleed easily. Despite the name, it’s not actually pus-producing ("pyogenic") nor a true granuloma in a medical sense. These small, red, bump-like lesions often occur on the skin or mucous membranes and can develop after minor injuries or due to hormonal changes, especially during pregnancy.
Pyogenic granulomas are usually harmless, but their rapid growth and tendency to bleed may cause concern. This article covers everything you need to know about pyogenic granulomas, including symptoms, causes, and the latest treatment options.

Causes of Pyogenic Granuloma

The exact cause of pyogenic granulomas isn’t always clear, but several contributing factors have been identified:

Minor Skin Trauma

One of the most common triggers is minor trauma or irritation, such as cuts, burns, or insect bites. The body may respond with excessive blood vessel growth, forming a granuloma.

Hormonal Changes

Pregnant women frequently develop a variant known as pregnancy tumor or granuloma gravidarum, often seen on the gums due to hormonal fluctuations.

Medications

Certain medications, including oral contraceptives, retinoids, and protease inhibitors, have been linked to pyogenic granuloma formation.

Other Risk Factors

• Poor oral hygiene (especially for oral lesions)
• Skin conditions like acne or eczema
• Age (more common in children and young adults)

Common Symptoms and Diagnosis

Pyogenic granulomas are typically:
• Small, bright red, or purple in color
• Dome-shaped and smooth or lobulated
• Rapid-growing, often within a few days or weeks
• Prone to bleeding easily, even with minimal contact
They most commonly appear on the hands, arms, face, or gums, but can occur anywhere on the body.

Diagnosis

A dermatologist or healthcare provider usually diagnoses pyogenic granulomas through a physical exam. If the lesion is atypical or to rule out other conditions like melanoma, a biopsy may be performed.

Treatment Options for Pyogenic Granuloma

Although pyogenic granulomas may go away on their own, many require treatment due to persistent bleeding or cosmetic concerns.

Non-Surgical Treatments

• Topical or oral antibiotics: Used if the lesion is infected
• Corticosteroid creams: May reduce inflammation in early stages
• Silver nitrate: A chemical cauterizing agent that helps stop bleeding and reduce lesion size

Surgical and Procedural Treatments

• Cryotherapy: Freezing the lesion with liquid nitrogen
• Curettage and cauterization: Scraping the lesion followed by heat cauterization
• Laser therapy: Often used for facial lesions to minimize scarring
• Surgical excision: Recommended for larger or recurring pyogenic granulomas, often followed by stitches
Note: Recurrence is possible, especially if the underlying trigger (like irritation or hormonal imbalance) isn’t addressed.

When to See a Doctor

You should consult a healthcare provider if:
• The lesion bleeds frequently or doesn’t heal
• It continues to grow or changes appearance
• You’re unsure if the bump is a pyogenic granuloma or another skin condition
Early medical evaluation helps ensure proper diagnosis and treatment.

Conclusion

A pyogenic granuloma may look alarming due to its rapid growth and tendency to bleed, but it is typically benign and manageable. With the right diagnosis and treatment approach—ranging from topical care to minor surgical procedures—most patients recover fully. If you notice a fast-growing, bleeding skin lesion, consult a healthcare provider to explore safe and effective treatment options.
