A full body dermatology exam, clinically known as a Total Body Skin Examination (TBSE), is a comprehensive, head-to-toe visual inspection of the skin, hair, and nails performed by a dermatology professional. The primary purpose of this routine assessment is the early detection of skin cancers, including melanoma, basal cell carcinoma, and squamous cell carcinoma. This systematic review allows the dermatologist to identify suspicious lesions, unusual growths, or subtle skin abnormalities. The TBSE also helps diagnose a wide variety of other dermatological conditions, ensuring timely intervention and treatment and making it a standard part of preventive healthcare.
Preparing for the Examination
Effective preparation ensures the dermatologist can perform a complete and accurate examination. Patients should arrive with a complete medical history, ready to discuss their lifetime sun exposure, any family history of skin cancer, and details about previous biopsies or skin treatments. The skin must be fully visible, requiring the removal of all makeup, heavy lotions, and jewelry that could obscure lesions on the face, neck, or body.
It is necessary to remove all nail polish from both fingernails and toenails, as skin cancers can occasionally develop in the nail beds. Hair should be worn down or easily undone, allowing the dermatologist to thoroughly inspect the entire scalp. Before the exam, the patient can point out any specific spots they have noticed are new, changing, or concerning.
The Step-by-Step Examination Process
The physical examination follows a systematic pattern to ensure no area of skin is overlooked. Patients change into a medical gown, and the dermatologist exposes only one section of skin at a time to maintain privacy. The inspection typically begins at the head, where the dermatologist parts the hair to examine the scalp, followed by a close look at the face, ears, and neck.
The doctor then moves to the trunk, inspecting the chest, abdomen, back, and buttocks, often asking the patient to shift positions for a clear view. The arms and legs are examined next, including the hands, palms, feet, and soles, as skin cancers can occur even in areas with minimal sun exposure. The dermatologist pays close attention to hard-to-see areas, such as the skin between the toes, the groin, and the underarm folds.
To gain a detailed view of suspicious lesions, the dermatologist uses a handheld, lighted magnification tool called a dermatoscope. This device allows for a non-invasive, magnified examination of the skin’s surface and the layers just beneath it. The dermatoscope helps differentiate between a benign mole and a potentially malignant growth. The entire procedure is performed under adequate lighting, allowing the doctor to meticulously assess the size, shape, color, and texture of every spot.
Post-Exam Discussion and Next Steps
Once the visual inspection is complete, the dermatologist discusses the findings and the proposed plan of action. The doctor classifies any spots found, noting which are benign and which require further evaluation or monitoring. If a lesion exhibits concerning features, such as asymmetry, irregular borders, varied color, or a change in size, a biopsy is likely recommended.
A skin biopsy is a minor procedure performed in the office. It involves injecting a local anesthetic to numb the area before a small tissue sample is removed and sent to a lab for microscopic analysis. The results from the lab determine if the lesion is cancerous or pre-cancerous, which then dictates the subsequent treatment. The discussion also includes personalized recommendations for sun protection, emphasizing the daily use of broad-spectrum sunscreen and avoidance of peak sun hours.
The dermatologist establishes a schedule for future screenings based on the patient’s individual risk factors. For most adults with no significant history, an annual TBSE is recommended. However, individuals with a personal or family history of melanoma, numerous atypical moles, or significant sun damage may require more frequent check-ups, often every three to six months, to maintain continuous surveillance.
