RESUMEN
El carcinoma de células escamosas de tiroides (CCET) es un tumor infrecuente y agresivo. Su etiología es incierta. Ante la presencia de carcinoma escamoso en la glándula tiroides debe excluirse la posibilidad de infiltración de un tumor originado en una estructura adyacente o de metástasis de otros carcinomas. El tratamiento de elección es la cirugía radical. La mayoría de los pacientes fallecen antes del año debido a progresión local de la enfermedad. Presentamos el caso de un paciente con una masa tiroidea, con diagnóstico histológico de carcinoma escamoso (con inmunohistoquímca negativa para tiroglobulina, TTF1 y calcitonina y positiva para p63 y citok5). Los estudios clínicos, endoscópicos y radiológicos excluyeron otros sitios de origen de carcinoma escamoso. Fue tratado con quimio y radioterapia, falleciendo por progresión local luego de 9 meses.
ABSTRACT
Primary squamous cell thyroid carcinoma (PSCTC) is a rare and aggressive tumor of uncertain origin. When squamous carcinoma is diagnosed, it is mandatory to exclude the possibility of primary tumor arising from an adjacent structure or representing metastases from a primary growth elsewhere. Aggressive surgical resection is the treatment of choice. However, the prognosis is poor, with a median survival of less than a year. Death is usually secondary to progression of local disease. We report a case of a patient presenting with a thyroid mass; biopsy was consistent with squamous cell carcinoma. On immunohistochemistry tumor cells were negative for TTF1, thyroglobulin and calcitonin. Cancer cells were positive for p63 and citok5. Extensive workup excluded the possibility of extrathyroid origin. The patient was treated with chemoradiotherapy; he died 9 months later due to local progression.
