Скачать или смотреть Brown Spots on Skin? 7 Signs It’s NOT Just Age

Not all brown spots are harmless → Some are just freckles or age spots, but others can be early melanoma, which is deadly if untreated.

Solar lentigo is the most common cause → Affects 90% of people over age 50 with fair skin; flat, uniform brown spots caused by UV light.

Post-inflammatory hyperpigmentation (PIH) → Affects up to 65% of people after acne, eczema, or injury; darker skin tones get more persistent spots.

Melasma is strongly hormonal → Affects up to 70% of pregnant women; more common in Asian, Hispanic, and Middle Eastern populations.

Seborrheic keratosis is benign but common → Present in ~90% of people over 60; looks stuck-on, waxy, or wart-like; not linked directly to sun.

Moles are usually harmless → But atypical moles have a ~10% risk of turning cancerous, higher with family history of melanoma.

Melanoma can look like a normal spot → Lifetime risk ≈ 2.6% in white populations; early detection saves lives — ABCDE rule is crucial.

Lentigo maligna → A slow-growing melanoma in situ on sun-damaged skin, most often in older adults; treat with surgery before it invades.

Acanthosis nigricans as a warning sign → Affects 7–13% of the population, often linked to insulin resistance, diabetes, or PCOS.

Differentiation matters → Each type has distinct hallmarks and look-alikes (e.g., freckles, tinea versicolor, pigmented basal cell carcinoma) — correct identification prevents missed melanoma.
