LESIONS ON THE FACE AND SUN-EXPOSED SKIN

OVERVIEW

Skin lesions on the face and other sun-exposed areas are common and may have many different causes. These areas—including the scalp, ears, eyelids, temples, nose, lips, and backs of the hands—receive cumulative ultraviolet (UV) exposure over time.

Chronic sun exposure produces cumulative changes in the epidermis, dermis, pigmentation, and superficial blood vessels, creating a background of photodamage in which different lesions can appear similar.

Benign growths, precancerous lesions, viral lesions, and skin cancers can therefore overlap in appearance, particularly on the face and other chronically sun-exposed areas.

COMMON LESIONS ON SUN-EXPOSED SKIN

Sun-exposed areas can develop many different types of skin lesions, including:

Seborrheic keratoses and other benign keratotic growths
Actinic keratoses related to cumulative UV exposure
Solar lentigines and other pigment changes
Viral warts, including common and flat warts
Sebaceous hyperplasia and other benign facial growths
Basal cell carcinoma
Squamous cell carcinoma
Melanocytic lesions, including benign nevi and melanoma

Several of these conditions can share similar colors, surface changes, scaling, crusting, or growth patterns, particularly against a background of chronically sun-damaged skin.

WHY LESIONS MAY APPEAR ATYPICAL ON SUN-DAMAGED SKIN

On chronically sun-exposed skin, lesions may:

Appear irregular or poorly defined
Become thickened, roughened, or scaly
Blend into surrounding sun-damaged tissue
Develop pigmentation, redness, or visible blood vessels
Mimic benign growths, inflammatory conditions, or other skin lesions

Clinical appearance is important, but it does not always establish the diagnosis.

FACIAL AREAS THAT REQUIRE SPECIAL CARE

Certain areas of the face and head deserve particular diagnostic attention because of their anatomy, cumulative sun exposure, and the importance of preserving surrounding structures and healthy tissue.

These areas include:

Eyelids and periocular skin
Medial canthal area at the inner corners of the eyes
Nose and perinasal skin
Temples and forehead
Ears
Lips and surrounding skin
Scalp, particularly in areas of thinning hair or chronic sun exposure

A lesion may remain relatively unchanged for years and later begin growing, thickening, crusting, bleeding, ulcerating, or repeatedly failing to heal. A change in the behavior of a longstanding lesion deserves renewed evaluation.

WHEN A “WART-LIKE” LESION DESERVES CLOSER EVALUATION

Not every rough, raised, or verrucous lesion is a viral wart. Squamous cell carcinoma, actinic keratosis, seborrheic keratosis, and other lesions can develop wart-like surface characteristics.

Particular attention should be given to lesions that:

Continue to enlarge
Change in texture or appearance
Bleed repeatedly
Crust, ulcerate, or become painful
Fail to heal
Behave differently after previous treatment

A lesion's history and behavior over time provide important diagnostic information in addition to its appearance.

IMPORTANCE OF ACCURATE DIAGNOSIS

Evaluation begins with clinical examination and can include dermoscopic assessment to examine structures and patterns not readily visible to the naked eye.

When the diagnosis remains uncertain or a lesion has suspicious characteristics, a biopsy is performed to obtain a tissue specimen. The specimen is sent to a pathology laboratory, where it is processed and examined microscopically by a pathologist or dermatopathologist.

The pathology report establishes the tissue diagnosis and guides subsequent management.

DIAGNOSIS BEFORE TREATMENT

The method used to treat a skin lesion depends first on what the lesion is. Clinically established benign lesions can often be treated directly, while suspicious or diagnostically uncertain lesions require tissue diagnosis before destructive treatment.

Depending on the diagnosis, management can include:

Clinical observation
Biopsy and histopathologic diagnosis
Surgical removal
Destructive treatment
Laser treatment for selected benign lesions
Treatment or referral appropriate to a diagnosed skin cancer

Cosmetic removal should never substitute for proper evaluation of a suspicious lesion.

KEY PATIENT TAKEAWAY

A lesion that changes its appearance or behavior over time, particularly on chronically sun-exposed skin, deserves medical evaluation.

Most skin lesions are not cancer. However, growth, bleeding, crusting, ulceration, failure to heal, or a new change in a longstanding lesion can provide important diagnostic information.

Evaluate Lesions on Sun-Exposed Skin

New, changing, persistent, or unusual lesions on the face and other sun-exposed areas should be evaluated to establish the diagnosis and determine appropriate care.
