ABSTRACT
Presentamos en nuestro trabajo un angiosarcoma epitelioide tiroideo, tumor raro y agresivo, observado en una paciente de 74 años, portadora de un bocio crónico eutiroideo. El tumor, que afectaba a la mayor parte de la superficie glandular del tiroides, mostró un patrón histológico infiltrante, con células epitelioides que tenían tendencia a formar luces vasculares. La inmunohistoquímica (CD31 y factor VIII) confirmaron el carácter angiomatoso de la neoplasia y permitieron establecer un diagnóstico diferencial con otros procesos malignos que pueden, igualmente, afectar a esta región anatómica (AU)

The tumor, which involved most of the glandular surface of the thyroid, showed an infiltrating histological pattern, with epithelioid cells displaying a tendency to form vascular lights. Immunohistochemical analysis (CD31 and factor VIII) confirmed the angiomatous nature of the neoplasm and enabled us to establish the differential diagnosis with other malignant processes that can also affect this anatomical area (AU)
