Follicular thyroid carcinoma with an unusual glomeruloid pattern of growth.
Cameselle-Teijeiro, J; Pardal, F; Eloy, C; Ruiz-Ponte, C; Celestino, R; Castro, P; Soares, P; Sobrinho-Simões, MWe describe an uncommon thyroid tumor in a 56-year-old woman. The widely infiltrating, angioinvasive neoplasm, 5 cm in diameter, exhibited a peculiar architectural growth pattern characterized by follicles with round to oval epithelial tufts growing within, often supported by a fibrovascular core mimicking the renal glomerulus. Colloid-empty follicles, tubular or elongated, were lined by pseudostratified tall, ...

Cystic tumor of the atrioventricular node of the heart appears to be the heart ...
Cameselle-Teijeiro J; Abdulkader I; Soares P; Alfonsín-Barreiro N; Moldes-Boullosa J; Sobrinho-Simões MWe studied a series of 10 solid cell nests (SCNs) of the thyroid and a case of cystic tumor of the atrioventricular node (CTAVN) of the heart and reviewed the literature. The CTAVN and SCNs appeared as cystic and/or solid (squamoid) structures mainly composed of polygonal or oval cells (main cells) admixed with occasional clear cells (neuroendocrine and C cells). Main cells were immunoreactive for simple and st...
