Enlarging Scalp Lesions: When Should You Have a Mole Checked?
Scalp Mole Evaluation in Katy and Houston, Texas
Many people discover bumps or moles on their scalp while brushing their hair, visiting a hairstylist, or experiencing changes in existing skin lesions. Because the scalp is difficult to examine regularly, changes may go unnoticed for months or even years.
At Village Dermatology, we recently evaluated a young woman concerned about several enlarging lesions on her scalp that had been present for approximately two years.
Patient Presentation
A 25-year-old female presented as a new patient for evaluation of multiple scalp lesions. She reported:
Lesions located on the scalp
Gradual enlargement over time
No pain or itching
Presence for approximately two years
Concern regarding whether the growths were dangerous
Because changes in skin lesions can occasionally signal skin cancer or atypical moles, a comprehensive dermatologic evaluation was performed.
Comprehensive Scalp Examination
A detailed scalp examination was completed, including hair inspection and dermoscopic evaluation.
Dermoscopy is a specialized diagnostic technique that allows dermatologists to closely examine skin lesions using magnification and polarized light. This tool helps distinguish benign lesions from growths that may require further investigation.
Upon examination, the lesions demonstrated reassuring features including:
Symmetrical appearance
Uniform coloration
Regular borders
Stable pigmentation patterns
These findings were most consistent with benign melanocytic nevi, commonly known as moles.
Understanding Benign Scalp Moles
Benign nevi are collections of pigment-producing cells within the skin. They are extremely common and can occur anywhere on the body, including the scalp.
Many scalp moles remain stable throughout life and require no treatment.
Typical characteristics of benign moles include:
Symmetry
Even color distribution
Smooth borders
Stable appearance over time
Although most scalp moles are harmless, periodic monitoring remains important because changes can occur over time.
Why Scalp Moles Deserve Special Attention
The scalp is one of the most difficult areas for patients to monitor.
Hair often conceals lesions, making it challenging to identify changes in:
Size
Shape
Color
Surface texture
Because scalp melanomas can sometimes be diagnosed later than lesions found on other parts of the body, routine skin examinations are particularly valuable.
Patients should seek dermatologic evaluation if a scalp lesion:
Rapidly enlarges
Changes color
Becomes irregular
Bleeds
Itches persistently
Develops ulceration
Courtesy Extraction of a Milia Cyst
During the same visit, a small milia cyst was identified on the right central frontal scalp.
Milia are tiny superficial cysts that contain keratin, a naturally occurring skin protein. These small white or flesh-colored bumps are completely benign and frequently occur on the face and scalp.
The patient elected to undergo a courtesy extraction during the visit.
What Causes Milia?
Milia form when keratin becomes trapped beneath the skin surface.
Common causes include:
Natural skin cell turnover
Skin trauma
Sun damage
Occlusive skincare products
Spontaneous development without a clear cause
Because milia are harmless, treatment is usually performed only for cosmetic reasons.
How to Monitor Moles at Home
Patients with moles should perform monthly self-skin examinations whenever possible.
The ABCDE warning signs can help identify concerning changes:
A – Asymmetry
One half differs from the other.
B – Border
Edges become irregular or poorly defined.
C – Color
Multiple colors develop within the lesion.
D – Diameter
Growth larger than approximately 6 mm.
E – Evolving
Any change in appearance over time.
If any of these changes occur, prompt dermatologic evaluation is recommended.
