Rabdomiosarcoma - Symptom

Nombres alternativos

Sarcoma del tejido blando; Rabdomiosarcoma alveolar; Rabdomiosarcoma embrionario; Sarcoma botrioides

Síntomas:

El síntoma más común es una masa que puede o no ser dolorosa.

Otros síntomas varían dependiendo de la localización del tumor.

  • Los tumores en la nariz o en la garganta pueden causar sangrado, congestión, problemas para deglutir o problemas neurológicos si se extienden al cerebro.
  • Los tumores alrededor de los ojos pueden causar protrusión ocular, problemas con la visión, hinchazón alrededor del ojo o dolor.
  • Los tumores en los oídos pueden causar dolor, hipoacusia o hinchazón
  • Los tumores en la vagina pueden estar protruyendo visiblemente del orificio vaginal.
  • Los tumores vaginales y vesicales pueden llevar a problemas para iniciar la micción o tener deposiciones, o a control deficiente de la orina.
  • Los tumores en los músculos pueden llevar a una protuberancia dolorosa y a menudo se cree que son una lesión.

Signos y exámenes:

El diagnóstico del rabdomiosarcoma con frecuencia tarda en realizarse debido a la falta de síntomas y porque la aparición del tumor puede coincidir con una lesión reciente. El diagnóstico oportuno es importante porque se trata de un tumor agresivo que se disemina rápidamente.

Se debe hacer un examen físico completo. Los exámenes que se hacen para diagnosticar esta afección abarcan:

  • Biopsia del tumor
  • Tomografía computarizada del tórax para buscar la diseminación del tumor
  • Tomografía computarizada del sitio del tumor
  • Biopsia de la médula ósea (puede mostrar que el cáncer se ha diseminado)
  • Gammagrafía ósea para buscar la diseminación del tumor
  • Resonancia magnética del sitio del tumor
  • Punción raquídea (punción lumbar)
