She has no idea how long it has been there and just noticed it a few weeks ago. Physical examination reveals a round, smooth, flesh-colored tumor. It is firm but not hard it has smooth borders. It measures 6 cm in diameter and is non-tender to palpation. The AGACNP suspects that this is a classic presentation of the most common chest wall tumor known as a
Correct Answer: B
Rationale: The correct answer is B: Lipoma. A lipoma is a common benign tumor made of fat cells. In this case, the patient's presentation of a painless, soft, round, flesh-colored lump with smooth borders is consistent with a lipoma. The absence of symptoms like pain, erythema, or tenderness further supports this diagnosis. Lipomas are usually non-tender to palpation and can grow to a significant size. The other choices (A, C, D) are not the correct answers because they do not align with the characteristics described in the patient's presentation. Neurolemma is associated with nerve sheath tumors, hemangioma with blood vessel tumors, and lymphangioma with lymphatic vessel tumors, none of which match the clinical findings in this case.
