The aim of this work was to correlate @entity3641 ( @entity3641 ) patterns and thyroid histology in @entity2743 ( @entity2743 ) @entity1 . Sixteen @entity1 with relapsed @entity2743 were studied. Before starting a new cycle of medical therapy with @entity3937 in decreasing doses for 3 to 6 months (baseline study), the @entity1 underwent functional, autoimmune, and @entity3641 studies. The same studies were carried out again just before surgery (presurgical study) after medical therapy had produced a normalization of thyroid hormone serum levels. The thyroid glands were histologically examined and their patterns were compared with @entity3641 patterns. Thirty-three normal subjects were used as a control group. At baseline, 6 @entity1 (group I) had intraparenchymal homogeneous vascular color spots or diffusely distributed over the parenchyma lobe or in areas alternating with avascular zones ( @entity3641 -A pattern). In 8 @entity1 (group II) the thyroid had vascular bands with avascular or poorly vascularized parenchymal areas ( @entity3641 -B pattern). In 2 @entity1 , the 2 patterns were present in the same thyroid (A-B pattern or mixed pattern). In these 2 @entity1 the histological aspects were more similar to the @entity3641 -B pattern than the @entity3641 -A pattern. The 2 groups of @entity1 differed in the velocity of systolic peak (VP) that was significantly higher in group I than in group II. In the presurgical study, no changes relative to @entity3641 patterns were observed in @entity1 groups I and II. The VP did not show any appreciable modifications in either group of @entity1 . The thyrotropin-stimulating antibodies (TRAb) returned to normal levels in group II, but not in group I. The 2 @entity3641 patterns, observed in the baseline study, were histologically characterized either by a richly vascularized parenchyma with @entity1373 ( @entity5651 , @entity3641 -A) or by fibrotic septation with prevalent @entity455 ( @entity3641 -B). In conclusion, this @entity3641 study in @entity2743 @entity1 showed 2 distinct vascular patterns. The thyroid glands were histologically characterized by either a richly capillary vascularized parenchyma ( @entity5651 , @entity3641 -A aspect) or by fibrotic septation with prevalent @entity1373 ( @entity5651 , @entity3641 -B aspect). Such differences may be secondary to a different duration of @entity1378 and/or intensity of TRAb thyroid stimulation.
