Fig. 4From: Pathological diagnosis of thyroid nodules based on core needle biopsies: comparative study between core needle biopsies and resected specimens in 578 casesCase classified as follicular neoplasm in both the CNB and resected specimens (H&E). a, The CNB specimen shows a microfollicular proliferative lesion with a fibrous capsule separating it from the normal follicles (× 50). b, High-power view shows proliferative follicles on the left of the capsule and the normal follicles on the right (× 200). c, An encapsulated follicular nodule with a complete thin capsule is prominent in the resected specimen. No capsular and vascular infiltration is detected (× 50). d, High-power view of the cells shows nuclei without features of papillary thyroid carcinoma (× 200)Back to article page
