Area of Science:

• Dermatology
• Oncology
• Surgical Techniques

Background:

• Nonmelanoma skin cancers, including basal cell carcinoma and squamous cell carcinoma, are common malignancies.
• Epiluminescence microscopy (dermatoscopy) is established for melanoma diagnosis but not yet for nonmelanoma skin cancers.
• Sun exposure is a known risk factor for squamous cell carcinoma, prompting public health initiatives for sun protection.

Purpose of the Study:

• To evaluate the utility of epiluminescence microscopy in diagnosing basal cell carcinomas.
• To investigate the association between sunlight exposure, hat use, and the risk of squamous cell carcinoma on the head and neck.
• To explore the impact of stress on the cutaneous immune response and describe a surgical technique for skin cancer defect repair.

Main Methods:

• Epiluminescence microscopy was assessed for its application in basal cell carcinoma diagnosis.
• A case-controlled analysis examined sunlight exposure and hat use in relation to squamous cell carcinoma risk.
• Studies reviewed included methods for assessing nonmelanoma skin cancer incidence rates and a modified rhombic flap technique for defect closure.

Main Results:

• Epiluminescence microscopy's role in basal cell carcinoma diagnosis is secondary to clinical acumen and biopsy.
• A strong association was found between squamous cell carcinoma and skin type, childhood sunburn, and adult sun exposure.
• An unexpected increased risk of squamous cell carcinoma was observed with hat use, possibly due to bias.

Conclusions:

• Diagnostic clinical acumen and biopsy remain definitive for nonmelanoma skin cancer diagnosis.
• While sun protection is crucial, the study suggests hat use is an unproven method for preventing squamous cell carcinoma.
• Stress can modulate the cutaneous immune response, and specialized surgical techniques are needed for complex skin cancer defect repair.
