During a routine physical examination, a nurse observes a 1-cm (0.4-in) lesion on a client's chest.The lesion is raised and flesh-colored with pearly white borders.The nurse should recognize that this finding is suggestive of which of the following types of skin cancer?

Choice A rationaleBasal cell carcinoma, the most common type of skin cancer, often presents as a raised, flesh-colored or pearly white papule or nodule with rolled, pearly borders and telangiectasia (visible small blood vessels). The description of the 1-cm raised, flesh-colored lesion with pearly white borders aligns with the typical appearance of basal cell carcinoma.Choice B rationaleMalignant melanoma is characterized by its irregular shape, asymmetrical borders, uneven color (often with shades of black, brown, red, white, or blue), and diameter greater than 6 mm. It can arise from existing moles or appear as a new pigmented lesion. The described lesion does not fit this profile.Choice C rationaleActinic keratosis is a precancerous skin condition that appears as rough, scaly patches on sun-exposed areas. These lesions are typically flat or slightly raised and can be skin-colored, reddish-brown, or have a whitish scale. The description of a raised lesion with pearly borders is inconsistent with actinic keratosis.Choice D rationaleSquamous cell carcinoma often presents as a firm, red nodule or a flat lesion with a scaly, crusted surface. It can also appear as a non-healing ulcer. While it can occur on the chest, the pearly white borders are more characteristic of basal cell carcinoma.
