Skin Lesions: Pyogenic Granuloma, Melasma, Skins Tags, and More (with Images)

Why Knowing Your Skin Matters

Your skin is your largest organ and a visible window into your overall health. Monitoring your skin regularly can help you spot changes that might indicate underlying health issues. Let's explore benign skin conditions and how to recognize and address them. None of the images used here are my own. I've included links to where I found each one. Note I used one image per condition, so not all skin tones are represented. I encourage you to look up other pictures because appearances could vary depending on skin tone.

Cherry Hemangiomas

What Are They?

Small, dome-shaped, bright red lesions caused by dilated capillaries. Over time, they may darken to purple.

Who Gets Them?

Common in late adulthood and the elderly, with a genetic predisposition.

Treatment

Removal is usually cosmetic but may be necessary if they bleed due to trauma. Methods include electro-cauterization and vascular laser therapy.

Pyogenic Granulomas (see image below)

Appearance

Soft, round lesions that are prone to bleeding, often triggered by physical trauma or hormonal changes during pregnancy. (See image of pyogenic granuloma above)

Treatment

Surgical excision is commonly used for removal.

Melasma (The Mask of Pregnancy)

What Is It?

They are dark patches on the face triggered by hormonal changes (e.g., pregnancy, birth control) and UV exposure.

Who Is Affected?

It is more common in women and those with darker skin tones.

Management

Sunscreen, depigmentation agents like hydroquinone, and other topical treatments can reduce pigmentation.

Acanthosis Nigricans

Description

Dark, velvety plaques, often in skin folds such as the neck or armpits.

Causes

Associated with endocrine disorders like diabetes, polycystic ovary syndrome, and certain medications.

Treatment

Address underlying conditions, or consider topical retinoids or laser therapy for persistent cases.

Seborrheic Keratosis

Characteristics

Waxy, raised lesions that appear as if they could be peeled off. It is common in older adults and often found on the torso, back, and arms.

May Serve as a Warning Sign

The sudden onset of multiple lesions may indicate internal issues like gastrointestinal cancer (known as the Leser-Trélat sign).

Treatment

Usually benign, but removal via cryotherapy or laser is possible for cosmetic reasons.

Skin Tags

What Are They?

Small, pedunculated growths in skin creases like the neck, armpits, or groin.

Risk Factors

Hormonal changes, obesity, and conditions like diabetes or Crohn's disease.

Removal Methods

Cryotherapy or simple surgical excision.

Key Takeaways

• Many skin lesions, such as cherry hemangiomas, melasma, and skin tags, are benign and primarily pose cosmetic concerns.

• Certain lesions, like seborrheic keratosis or acanthosis nigricans, may indicate underlying health issues and warrant further medical evaluation.

• Always consult a healthcare provider to assess new or changing skin lesions.

Frequently Asked Questions (FAQ)

What should I do if I notice a new or changing lesion on my skin?

If you notice a new skin lesion or a change in an existing one, such as growth, color change, or bleeding, it’s important to consult a dermatologist or primary care physician. While many lesions are benign, some changes can be signs of skin cancer or other underlying conditions.

Are cherry hemangiomas and pyogenic granulomas dangerous?

Cherry hemangiomas and pyogenic granulomas are generally benign and not harmful. However, they can bleed if traumatized. If they cause discomfort or cosmetic concerns, consider excision or laser therapy. Always consult a doctor for proper diagnosis and treatment options.

Can melasma go away on its own after pregnancy or birth control use?

Melasma, often triggered by pregnancy or hormonal contraceptives, may fade after hormone levels stabilize. However, it may not completely disappear without treatment. Using sunscreen and depigmentation agents like hydroquinone can help reduce its appearance.

Are skin tags and seborrheic keratoses preventable?

Skin tags and seborrheic keratoses are often linked to genetics, age, and certain conditions like obesity or diabetes. While you can’t always prevent them, maintaining a healthy weight and managing conditions like diabetes may reduce their occurrence.

When should I be concerned about seborrheic keratoses?

Seborrheic keratoses are typically benign. However, if you notice a sudden appearance of many lesions or changes in color, size, or texture, it could indicate an underlying condition, such as gastrointestinal cancer. In such cases, consult a healthcare provider for evaluation.
