Review[Differentiated thyroid cancer--peculiar morphological and clinical forms].
The most common clinical presentation of differentiated thyroid cancer (DTC), consisting of papillary and follicular adenocarcinoma (with their histological variants), is the solitary thyroid nodule. A review of the literature is performed in order to describe particular forms of DTC, in terms of incidence, diagnosis and treatment: occult carcinoma, carcinoma on aberrant thyroid tissue, "functional" thyroid carcinoma and familial non-medullary carcinoma. A particular interest is shown to the coexistence of malignancy with benign thyroid diseases, such as goiter, hyperthyroidism and Hashimoto's thyroiditis, as well as parathyroid adenoma. In conclusion, the authors emphasize that the association of carcinoma with benign thyroid conditions is not rare and it substantiate an aggressive approach in regard to diagnosis and treatment, increasing the indication for surgery and, moreover, for total thyroidectomy.

[Checking a model of cardiac segmentation of the left half of the heart].
The present work is aimed to study the distribution of the coronary arteries to the left ventricle; 120 fresh and prepared human hearts harvested from healthy individuals of both sexes aged 4 to 78 have been used. The denomination of the cardiac segments is the one used by Liberato, Didio & Rodrigues in 1983. Starting from this model, we sought for sustaining or invalidating arguments. ⋯ The segments are separated by intersegmental planes whose position depends of the degree of development of each cardiac segment. No significant differences were observed in what concerns the extension of the cardiac segments and the position of intersegmental planes in relation to sex. The segments can be totally independent or slightly dependent to the blood supply of the neighbouring segments.
