Birthmarks & Moles
Birthmarks and moles are usually harmless — but they deserve medical attention when they change, cause symptoms, or affect confidence. At Allodermis we assess each mark medically, rule out risk, and offer conservative, science-led treatments only when appropriate.
Key Facts About Birthmarks & Moles
Birthmarks are skin areas caused by local differences in pigment cells or blood vessels present at birth or appearing in early childhood.
Two broad categories: vascular birthmarks (port wine stains, hemangiomas) and pigmented birthmarks/nevi (cafe au lait spots, congenital melanocytic nevi).
Most birthmarks are benign; a small subset (large congenital melanocytic nevi) carries a measurable, though low, long-term melanoma risk.
What Are Birthmarks & Moles?
Birthmarks
Developmental differences of blood vessels or pigment formed in utero or in early childhood. They range from flat pink angel kiss marks to raised hemangiomas or deep blue dermal melanocytoses.
Moles (Nevi)
Localised proliferations of melanocytes (pigment cells). Most are benign; however, changes in size, colour, shape, bleeding, or itching require dermatologist review.
Types of Birthmarks & Moles
Vascular Birthmarks
Port Wine Stain
Flat, pink to purple; present at birth; often persistent. Caused by capillary malformation.
Infantile Hemangioma
Raised, red (strawberry) lesion that proliferates after birth then involutes. Medical therapy (propranolol) is effective for problematic lesions.
Nevus Simplex (Stork Bite)
Common, pale pink macules that often fade on their own during childhood.
Pigmented Birthmarks & Moles
Congenital Melanocytic Nevus (CMN)
Present at birth; size matters for risk stratification. Larger nevi carry higher surveillance requirements.
Cafe au Lait Macules
Light brown flat patches, often benign. Multiple lesions may suggest syndromic conditions.
Dermal Melanocytosis (Mongolian Spot)
Bluish-grey macules that usually fade in childhood.
Why Do They Form?
Vascular Marks
Focal overgrowth or malformation of capillaries/venules during fetal vasculogenesis.
Pigmented Marks / Nevi
Localised proliferation or persistence of neural-crest-derived melanocytes during embryogenesis. Genetic and developmental factors explain most cases.
How We Assess (Allodermis Clinical Pathway)
History & Photos
Age at appearance, growth pattern, bleeding, symptoms, family history.
Clinical Exam + Dermoscopy
Characterise pigment pattern or vascular architecture.
Non-Invasive Imaging
Doppler/ultrasound for deep vascular lesions or pre-treatment planning.
Biopsy / Histology
Reserved for suspicious, rapidly changing, or symptomatic lesions.
Multidisciplinary Referral
Oculoplastics, paediatric surgery, or oncology when markers suggest syndromic associations or deeper risk.
See a Dermatologist Urgently If...
Changes size, shape, colour or bleeds
Develops pain, ulceration, or rapid growth
Large congenital melanocytic nevus (especially large/giant CMN) — discuss melanoma risk and surveillance
Treatment Options
We only treat when there is medical indication, functional impairment, or cosmetic concern after shared decision-making.
Vascular Lesions
Pulsed Dye Laser (PDL)
First-line for port wine stains. Multiple sessions required. Pigmentary risk in darker skin types must be managed.
Propranolol (Oral)
First-line medical therapy for problematic infantile hemangiomas. Early initiation improves outcomes.
Radiofrequency / Electrodessication
For small vascular or nodular residues. Safe in hands of experienced operators.
Pigmented Birthmarks & Moles
Q-Switched Nd:YAG / Pigment Lasers
Effective for many pigmented lesions (epidermal and some dermal). Multiple sessions, conservatively used for skin of colour.
Radiofrequency Excision / Shave + Histology
Precise removal with minimal scarring. Recommended for suspicious or symptomatic moles to allow histopathology.
Surgical Excision
Gold standard when malignancy cannot be excluded or for large/complex lesions.
Practical Guidance
Most laser courses need multiple sessions with spacing per protocol and strict sun protection.
Vascular birthmarks may lighten but can recur or re-darken over years — long-term follow-up is needed.
For infantile hemangiomas, propranolol monitoring is required (dose, cardiac/pulmonary checks).

Frequently Asked Questions
Most are benign. Rarely, certain congenital melanocytic nevi or rapidly changing moles require surveillance or removal.
PDL can significantly lighten many port wine stains, but complete permanent clearance isn't guaranteed; some lesions can re-darken over years.
If it changes in size, colour, border, bleeds, itches, or looks irregular — dermatology evaluation and possible biopsy are indicated.
Yes — but they require conservative settings and experienced operators to reduce risks of hyper/hypopigmentation. Allodermis protocols are skin-type-specific.
Many are monitored; treatment (e.g., propranolol) is recommended early for lesions that threaten function (eye, airway) or are at high risk of complications.
