Summary: | Merkel cell tumour is a rare skin tumour of high malignancy, poor prognosis and low survival. It is characterized by its tendency to lymph node and vascular invasion and by a high percentage of locoregional recurrence in the year following surgical removal. It affects adults between 60 and 80 years of age and often occurs in the head and neck. We present the case of an 85-year-old man presenting with an ulcerated gluteal mass of 4 months’ evolution. Diagnosis was by histopathological and immunohistochemical study. Early diagnosis and appropriate treatment are important to improve the prognosis of these patients.
El tumor de células de Merkel es un tumor cutáneo raro, de elevada malignidad, mal pronóstico y baja supervivencia. Se caracteriza por su tendencia a la invasión ganglionar y vascular, y por un alto porcentaje de recurrencia locorregional en el año siguiente a la extirpación quirúrgica. Afecta a adultos entre los 60 y 80 años, y se localiza preferentemente en cabeza y cuello. Presentamos el caso de un varón de 85 años que acude por masa glútea ulcerada de 4 meses de evolución. El diagnóstico se realizó por estudio histopatológico e inmunohistoquímico. Un diagnóstico precoz y un tratamiento adecuado son importantes para mejorar el pronóstico de estos enfermos. |
