CASSOLA SANTANA, Juan Ramón; GUERRA MESA, José Luis  e  PERALTA PEREZ, Raúl. Quistes del tiroides: ¿Malignidad controvertida?. Rev Cubana cir [online]. 1999, vol.38, n.2, pp. 69-73. ISSN 1561-2945.

The real incidence of malignant cystic lesions of the thyroid is not well known in Cuba. To study this aspect of the thyroid diseases and to evaluate the usefulness of the fine needle aspiration biopsy in their diagnosis are the main objectives of this paper. 104 patients who suffered from nodular lesions of the thyroid as a form of clinical presentation were operated on from 1987 to 1990. All patients underwent fine needle aspiration biopsy in the operating room immediately after the operation. The material obtained as well as the surgical pieces were diagnosed by different pathologists. A total of 45 (43.2 %) cystic lesions was obtained. 12 (27 %) of them were malignant. The fine needle aspiration biopsy showed a sensitivity of 83 % and a specificity of 97 %, with positive and negative predictive values of 90 and 94 %, respectively. The cystic thyroid lesions may be the site of malignant neoplasias. This type of lesions should not be considered as a synonym of benignity
