For the histopathological diagnosis of lymphoma, lymph node excision biopsies are regarded as standard of care. In contrast, for the diagnosis of carcinoma and deep-seated tumors, core needle biopsies (CNBs) are accepted as a sufficient sampling method. We evaluated a diagnostic algorithm for peripheral lymphadenopathy starting with ultrasound-guided CNB followed by excisional biopsy in ambiguous cases. ⋯ Ultrasound-guided CNBs are a safe, quick, and valid tool for the workup of lymphadenopathy. Yet, a benign diagnosis from CNB must be completed by a secondary biopsy if clinical presentation suggests malignant disease.
