"Doctor, Should I Be Worried About This Mole on My Arm?"
A Full Body Skin Exam Reveals Common Benign Skin Growths in a Young Texas Patient
At Village Dermatology, one of the most common questions we hear from patients in Katy and Houston is:
"Doctor, should I be worried about this mole on my arm?"
A recent patient visit highlights why routine skin examinations are an important part of maintaining healthy skin and why many seemingly concerning lesions turn out to be completely benign.
Patient Case Overview
A 31-year-old woman presented to Village Dermatology for her annual full body skin examination. She had several skin lesions she wanted evaluated, including spots on her left upper arm and left lower leg.
Although the lesions were not causing pain, itching, or bleeding, she wanted reassurance that they were not dangerous and sought a comprehensive skin cancer screening.
Comprehensive Skin Examination
A thorough full body skin examination was performed, including evaluation of:
Scalp and hair
Face and neck
Chest and abdomen
Back
Arms and legs
Hands and feet
Nails
Other skin surfaces
A dermatoscope was utilized to closely examine pigmented lesions and identify features that may indicate skin cancer or other concerning changes.
Findings: Benign Nevi (Moles)
The primary lesion of concern on the left upper arm measured approximately 6.5 mm and demonstrated reassuring features:
Symmetrical appearance
Regular borders
Even pigmentation
Stable clinical appearance
The lesion was diagnosed as a benign nevus (common mole).
Benign nevi are collections of pigment-producing cells called melanocytes. Most adults develop multiple moles throughout their lifetime, and the vast majority are harmless.
Additional Benign Findings
During the examination, several other common benign skin conditions were identified.
Seborrheic Keratoses
A waxy, pigmented growth on the trunk was diagnosed as a seborrheic keratosis.
These growths are:
Extremely common
Non-cancerous
Often hereditary
More common with age
Many patients mistake seborrheic keratoses for skin cancer because they can appear dark, raised, and irregular.
Lentigines (Sun Spots)
The patient also demonstrated lentigines, commonly called:
Age spots
Sun spots
Liver spots
These develop due to cumulative ultraviolet (UV) exposure and are especially common in sunny climates like Katy and Houston.
While benign, they serve as a reminder that the skin has experienced sun damage over time.
Cherry Angiomas
Multiple cherry angiomas were noted during the examination.
These bright red vascular growths are:
Benign
Extremely common
Typically increase with age
Not associated with skin cancer
Dermatofibroma
A dermatofibroma was identified on the left upper back.
Dermatofibromas are firm, scar-like nodules that often develop following minor trauma such as:
Insect bites
Ingrown hairs
Small cuts or scratches
These lesions are benign and usually require no treatment unless they become symptomatic.
Changes in Skin Texture
The patient also had an area of altered skin texture on the forehead. While no definitive diagnosis was established during the visit, conservative management with moisturization and topical tretinoin therapy was initiated.
Close monitoring was recommended to ensure no progression occurs.
Why Annual Skin Exams Matter
Many patients assume they only need a skin examination if they have a suspicious lesion. However, routine skin checks provide several important benefits:
Early detection of melanoma
Identification of precancerous lesions
Monitoring of changing moles
Education regarding sun protection
Peace of mind regarding benign growths
Even younger adults can develop skin cancer, making periodic skin examinations an important preventive healthcare measure.
How to Monitor Moles at Home
Patients are encouraged to perform monthly self-skin examinations using the ABCDE rule:
A – Asymmetry
One half differs from the other.
B – Border
Edges are irregular or poorly defined.
C – Color
Multiple colors or uneven pigmentation.
D – Diameter
Larger than 6 mm or increasing in size.
E – Evolving
Any change in appearance, symptoms, or behavior.
If a mole changes in size, shape, color, begins itching, bleeding, or becomes painful, evaluation by a board-certified dermatologist is recommended.
Protecting Your Skin in Texas
Residents of Katy and Houston experience significant UV exposure throughout the year. Consistent sun protection remains one of the most effective ways to prevent skin cancer and premature aging.
Recommended sun safety measures include:
Daily broad-spectrum SPF 30 or higher sunscreen
Reapplication every two hours outdoors
Sun-protective clothing
Wide-brimmed hats
UV-blocking sunglasses
Seeking shade during peak sunlight hours
