RESUMO

El microcarcinoma papilar de tiroides es definido como un tumor de un cm o menos de diámetro mayor. La mayoría permanecen ocultos clínicamente, siendo un hallazgo en autopsias hasta en 36%. La presentación oculta ocurre hasta en un 10 a 26% de todas las neoplasias malignas de tiroides y se define como la presencia de ganglios metastásicos de carcinoma papilar de tiroides en ausencia de lesión primitiva tiroidea evidente durante la exploración clínica y ecográfica. El objetivo de este trabajo es el reporte de dos casos donde el diagnóstico de cáncer de tiroides se realizó a través de su presentación metastásica cervical, siendo el estudio anatomopatológico de la pieza de resección quirúrgica el que devela la presencia de un microcarcinoma papilar. Si bien el tratamiento del de estas lesiones es controversial, existen elementos que sellan la necesidad de resolución quirúrgica. En el debut metastásico ganglionar cervical, está indicada la tiroidectomía total con el vaciamiento ganglionar cervical radical modificado ipsilateral y central. El raidioyodo postquirúrgico será empleado en forma complementaria ante la persistencia, recurrencia o elementos de alto riesgo.


Papillary thyroid microcarcinoma is defined as a tumor one cm or less in diameter. Most remain clinically hidden, being an autopsy finding in up to 36%. Occult presentation occurs in up to 10% to 26% of all thyroid malignancies and is defined as the presence of metastatic nodes from papillary thyroid carcinoma in the absence of a primitive thyroid lesion evident on clinical and ultrasound examination. The objective of this work is the report of two cases where the diagnosis of thyroid cancer was made through its cervical metastatic presentation, being the pathological study of the surgical resection specimen that reveals the presence of a papillary microcarcinoma. Although the treatment of these lesions is controversial, there are elements that seal the need for surgical resolution. In cervical lymph node metastatic debut, total thyroidectomy with modified ipsilateral and central radical cervical lymph node dissection is indicated. Post-surgical radiation iodine will be used in a complementary way in the event of persistence, recurrence or high-risk elements.

RESUMO

Objective@#Micropapillary thyroid carcinoma (micro-PTC) has a good prognosis but a number of cases will present with aggressive behavior. This study aims to determine the clinical outcomes with surgical management and histopathologic characteristics of Filipino patients with micro-PTC at University of Santo Tomas Hospital. @*Methodology@#139 patients were diagnosed with micro-PTC from the year 2004-2011. Seventy five patients had complete data and were included in this retrospective study. Chi square test with Yates correction, T-test for tumor diameter, statistical means and percentages were used in data analysis.@*Results@#A total of 1,689 thyroid surgeries were done between 2004 and 2011. There were 1,054 patients (62.4%) diagnosed with benign thyroid tumor(s) and 635 patients (37.6%) with well-differentiated thyroid carcinoma. Of these, 139 (22%) patients have micro-PTC. The prevalence rate of micro-PTC was 22%, with a female predominance (86.6%). The patients’ ages ranged from 24-80 years old with a mean age of 47 years. Comparison of groups showed that having either incidental or non-incidental micro-PTC is independent of the clinical variables of the patient. Two (2.6%) patients initially presented with cranial and supraclavicular metastasis. This study had a low recurrence rate (5.3%) and a mortality rate of 1.3%. @*Conclusion@#Male gender is the only significant variable for lymph node and distant metastasis. The patient’s age, family history of cancer, number of foci, size and histological type of tumor have no prognostic value.
