Angiokeratoma of Fordyce: Symptoms, Causes, and Treatment in the UK

Angiokeratoma of Fordyce refers to small, dark red, blue, or purple bumps that typically appear on the scrotum, though they can also be found on the shaft of the penis or the groin. These lesions are technically known as vascular ectasias, which means they are formed by the dilation (widening) of small blood vessels (capillaries) just beneath the surface of the skin.

In the UK, these are frequently encountered in primary care and sexual health clinics. While the appearance of spots in the genital area can be alarming, Angiokeratomas of Fordyce are entirely benign (non-cancerous) and are not associated with any sexually transmitted infections (STIs). They are most common in men over the age of 40, though they can appear in younger men as well.

Identifying Angiokeratoma of Fordyce involves looking for specific characteristics. These spots usually have the following features:

• Colour: Range from bright red to deep purple or almost black.
• Size: Typically small, between 1mm and 5mm in diameter.
• Texture: They may feel slightly raised or dome-shaped, and the skin over them may appear thickened (hyperkeratotic).
• Distribution: They often appear in clusters across the scrotum.
• Pain level: Generally painless, though they may itch occasionally.

One of the most notable traits of these spots is that they may bleed easily if scratched or during sexual activity, as the blood vessels are very close to the skin's surface. According to NHS clinical knowledge, this minor bleeding is one of the primary reasons men seek a medical consultation.

The exact cause of Angiokeratoma of Fordyce is not fully understood, but it is not caused by poor hygiene, viruses, or bacteria. Most medical professionals and NICE (National Institute for Health and Care Excellence) guidelines suggest they are related to increased pressure in the local veins.

Factors that might contribute to their development include:

• Increased local venous pressure: Conditions like a varicocele (enlarged veins in the scrotum) or inguinal hernias may increase pressure, though many men have these spots without any underlying issues.
• Age: The prevalence increases significantly with age as blood vessel walls naturally weaken.
• Thinning skin: As the skin on the scrotum thins over time, these dilated vessels become more visible.

Are they contagious?

It is crucial to understand that Angiokeratoma of Fordyce is not contagious. You cannot pass them to a partner, and they are not a sign of an underlying STI like genital warts or herpes.

If you notice new spots on your genitals, it is natural to feel anxious. While Angiokeratomas are harmless, a professional diagnosis is important to rule out other conditions such as genital warts, molluscum contagiosum, or in very rare cases, malignant melanoma.

You should consider a consultation if:

• The spots are bleeding frequently or heavily.
• You are concerned about the diagnosis or worried about STIs.
• The appearance of the spots is causing you significant psychological distress.
• The spots have changed shape, size, or colour rapidly.

Choosing to speak to a GP online in the UK is often the most comfortable way to address these concerns. Our clinicians can review clear photographs of the area or conduct a video consultation to provide a preliminary assessment and offer reassurance or advice on the next steps.

For the majority of men, no treatment is required for Angiokeratoma of Fordyce. They do not pose a risk to your health. However, if the spots bleed repeatedly or if their appearance affects your confidence, several private treatment options are available in the UK:

• Cryotherapy: Freezing the lesions with liquid nitrogen.
• Laser Therapy: Using targeted light to collapse the blood vessels. This is often preferred for cosmetic results.
• Electrocautery: Using a small electrical current to seal the vessels.
• Excision: Surgically removing individual spots, though this is rare for this specific condition.

It is important to note that cosmetic removal is rarely available on the NHS, as it is considered a non-essential procedure. Most patients choose to leave them alone once they have been reassured that the spots are benign.

Maintaining good genital health involves regular self-checks. While Angiokeratomas are not dangerous, becoming familiar with what is 'normal' for your body helps you spot changes that might require attention. When checking, look for changes in the testicles themselves, such as lumps or heaviness, which should always be reported to a doctor immediately.

If you have been diagnosed with Angiokeratomas, avoid scratching the area, as this can lead to minor infections or bleeding. Wearing supportive underwear may also reduce the risk of irritation if the spots are prominent.
