ABSTRACT
Se presenta un caso de metástasis de carcinoma papilar de tiroides de localización en el espacio parafaríngeo con clínica inicial de características obstructivas a nivel locorregional (disfagia progresiva y desviación contralateral de la amígdala correspondiente). En el estudio de imagen (TAC y RNM), la masa adoptaba una morfología especial, pero el diagnóstico no se confirmó hasta que se realizó el estudio anatomopatológico. Este espacio no es un lugar frecuente de asiento de metástasis ni de carcinomas tiroideos ni del resto de tumores de cabeza y cuello, por lo que, hasta la fecha, sólo se han descrito 5 casos similares en la literatura médica
This is a case report of a papillary thyroid carcinoma metastatic to the parapharyngeal space, that presented with local obstructive symptoms (dysphagia and displacement of the ipsilateral tonsil). The diagnosis was suspected by imaging studies (CT and MRI) but not confirmed until histological examination. It is not common for such tumors to metastasize to the parapharyngeal space. This is the reason why, to our knowledge, there have been described only five similar cases previously

Laryngeal presentation of Malignat Fibrous Histiocytoma (MFH) is uncommon. It is more prevalent in elderly males. The most frequent form of laryngeal presentation is as subepithelial nodules, and its clinical behaviour is variable and unpredictable. Microscopically, it is a tumour with two well differentiated components: histiocitic and fibroblastic, with several different structural patterns that can make histologic diagnosis a difficult one. We present two cases of MFH of the larynx, and a review of the literature.

El fibrohisticitoma (FHM) es una tumoración infrecuente en cabeza y cuello, y todavía mas en la laringe. Es más prevalente en varones de mediana edad, pudiendo aparecer a cualquier edad. la presentación más habitual laringea es en forma de nódulos subepiteliales. el comportamiento clínico es variable e impredecible. Microscópicamente, es un tumor con dos componentes diferenciados: histiocítico y fibroblástico, con diferentes patrones estructurales que pueden dificultar el diagnostico histológico. Se presentan dos casos de FHM laríngeos y se revisa la bibliografía(AU)
