Resumen

Presentamos un caso de tumor vesical con diferenciación pseudosarcomatosa del estroma.

Son extremadamente raros (sólo se había descrito 78 casos en el mundo hasta el año 2001). También son llamados carcinosarcomas heterólogos, dentro de los cuales se encuentran los llamados carcinosarcomas con células gigantes tipo osteoclasto, que se caracterizan por ser positivos para vimentina y fosfatasa ácida y negativos para marcadores epiteliales (citoqueratinas de bajo peso y lisozima).

Palabras clave:
Carcinosarcoma heterólogo
Diferenciación estromal pseudosarcomatosa
Células tipo osteoclasto
