Question

question 85
jacob reports a neck mass that has been present intermittently for 5 or 6 weeks which varies in size. the provider palpates a lymph node measuring 1.25 cm. which test will provide proper histologic diagnosis for this patient?
bone marrow aspirate
computed tomography (ct) scan with intravenous (iv) contrast
lymph node biopsy
positron emission tomography (pet) scan

Explanation:

A lymph node biopsy is the gold - standard for obtaining a histologic diagnosis of a lymph node mass. A bone marrow aspirate is more relevant for diseases like leukemia or certain hematological disorders affecting the bone marrow. A CT scan with IV contrast is useful for imaging the anatomy and assessing the size, location, and relationship of the lymph node to surrounding structures but does not provide a histologic diagnosis. A PET scan is more about assessing metabolic activity (e.g., for cancer staging in some cases) rather than a histologic diagnosis.

Answer:

Lymph node biopsy
