What Does Amelanotic Melanoma Look Like in Albinism?

Standard skin cancer advice tells people to look for the “ABCDEs” of melanoma, primarily focusing on dark, changing moles. However, this advice does not apply to individuals with oculocutaneous albinism (OCA). Because people with OCA produce little to no melanin (the pigment that gives skin and moles their color), their melanomas rarely appear brown or black ^[1]. Instead, they can develop amelanotic melanoma—a type of skin cancer that lacks typical dark pigment ^[2].

Note: While this page focuses specifically on melanoma, it is important to know that non-melanoma skin cancers like squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are much more common in people with albinism ^[3]. They often present with the exact same symptoms described below, which is why having a doctor check any new or changing spot is so important ^[4].

How Amelanotic Melanoma Appears

Because it lacks color, amelanotic melanoma requires careful attention as it is easily missed and can mimic harmless skin conditions ^[5]. In someone with albinism, a normal mole or freckle is usually pale, flat, and light pink. If you have OCA, you should be on the lookout for:

• Pink or red bumps: A new, firm bump that might look like an insect bite, a pimple, or a cyst but does not go away after a few weeks ^[6].
• Scabs that won’t heal: A sore or ulceration that persists, bleeds easily when bumped or dried with a towel, and doesn’t heal ^[7][8].
• Scaly patches: Ill-defined, rough, or red plaques that might initially be mistaken for dry skin, eczema, or sun damage ^[4].
• Growing or changing spots: Any flesh-colored or reddish spot that is rapidly growing or changing in shape or texture ^[9].

These spots can appear anywhere on the body, though they often show up in sun-exposed areas.

The “Ugly Duckling” Method

Since you cannot rely on dark colors to warn you of danger, dermatologists recommend using the “Ugly Duckling” sign ^[10]. This means looking for a spot that stands out because it looks or acts differently than any other freckle or mark on your body ^[11]. For example, if you have many flat, pale freckles but suddenly develop a raised, pink, firm bump, that bump is the “ugly duckling.”

Even for skin doctors, amelanotic melanoma is challenging to diagnose by sight alone because regular moles (nevi) in people with OCA can have blood vessel patterns that look remarkably similar to amelanotic melanoma under a dermatologist’s magnifying tool ^[12]. Because of this, a tissue biopsy (removing a small piece of the spot to examine in a lab) is almost always required for a definitive diagnosis ^[1][13].

What You Can Do

Due to the lack of protective melanin, people with OCA have a significantly higher risk of developing skin cancers, often at a younger age ^[14][15].

• Check your skin monthly: Because OCA often involves visual impairment, standard visual self-checks can be very difficult. Rely on touch to feel for new, firm bumps or rough patches. Ask a trusted partner, family member, or caregiver to help you visually check areas you cannot see well.
• Take photos: If you or a loved one spots a new “pimple” or bug bite, use a smartphone to take a time-stamped photo. This helps you track changes and proves to your doctor exactly how long it has been there.
• Seek expert care: Find a board-certified dermatologist who has experience with high-risk patients or albinism ^[16]. Schedule professional, full-body skin exams every 6 to 12 months, or as recommended by your doctor.
• Advocate for biopsies: If you point out a suspicious, non-healing pink or red spot, remind your doctor that melanomas in OCA often lack pigment and ask if a biopsy is appropriate ^[17].
• Protect your skin: Prevention is critical. Consistently use broad-spectrum sunscreen, wear UPF-rated clothing, and seek shade whenever possible.
