Read the first 7 Skin Cancer Screening & Education flashcards as text

  1. Which of the following best describes an actinic keratosis (AK)?

    Answer: A premalignant lesion that may progress to squamous cell carcinoma

    Actinic keratoses are UV-induced premalignant lesions with potential to progress into invasive squamous cell carcinoma if left untreated.

  2. Field cancerization in the context of skin cancer education refers to:

    Answer: A widespread area of UV-damaged skin harboring subclinical genetic mutations

    Field cancerization describes large areas of chronically sun-damaged skin with widespread mutagenic changes that predispose to multiple skin cancers.

  3. A patient on long-term immunosuppressive therapy after organ transplantation is at highest risk for which skin cancer?

    Answer: Squamous cell carcinoma

    Immunosuppressed transplant recipients have a dramatically elevated risk—up to 65-fold—for squamous cell carcinoma compared to the general population.

  4. The 'ugly duckling' sign in melanoma screening refers to:

    Answer: A lesion that looks noticeably different from a patient's other moles

    The 'ugly duckling' concept holds that a melanoma often stands out as morphologically distinct from a patient's other nevi, prompting further evaluation.

  5. Breslow thickness in melanoma staging measures:

    Answer: Vertical depth of tumor invasion from the granular layer in millimeters

    Breslow thickness is the vertical depth of melanoma invasion measured in millimeters from the epidermal granular layer to the deepest tumor cell.

  6. Which SPF rating is the minimum recommended by the American Academy of Dermatology for daily photoprotection?

    Answer: SPF 30

    The AAD recommends a broad-spectrum sunscreen of at least SPF 30 for adequate daily photoprotection against both UVA and UVB radiation.

  7. Keratoacanthoma is clinically important in the context of SCC because:

    Answer: It can be histologically indistinguishable from well-differentiated SCC

    Keratoacanthoma and well-differentiated SCC can look identical on histology, so most dermatologists treat keratoacanthoma as a variant of SCC.
