There are several basic principles that apply to the clinicopathologic syndrome produced by polychlorinated biphenyls (PCBs). They are as follows: The degree of halogenation and position of the halogen atoms determine the potency of PCB, PBB, CDD, CDF and CN; in a given species of animals, the clinicopathologic syndrome induced by PCB is comparable to that induced by polybrominated biphenyls (P...

Immunoblastic lymphadenopathy (lBL)-like T-cell lymphoma is a distinct peripheral T-cell lymphoma. which closely resembles angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) and/or IBL. but is characterized by focal or sheet-like proliferation of immunoblasts and pale cells of T-cell nature. In this report. 36 patients with IBI-like T-cell lymphoma were analyzed. The disease is clini...

OBJECTIVE To evaluate the association of the BRAF(V600E) mutation with sonographic features and clinicopathologic characteristics in a large population with conventional papillary thyroid carcinoma (PTC). METHODS We retrospectively reviewed the sonographic features, clinicopathologic characteristics, and presence of the BRAF(V600E) mutation in 688 patients who underwent thyroidectomy for conv...
