[Inflammatory myofibroblastic genitourinary tumor: The challenge of controlling and monitoring an non frequent oncological disease.] / Tumor miofibroblástico inflamatorio genitourinario: el desafío del control y seguimiento de una enfermedad oncológica infrecuente.

OBJECTIVE: The inflammatory myofibroblastic tumor (IMT) is a neoplasia with intermediate biological potential, infrequent, with an unpredictable clinical prognosis and a low recurrence rate after an effective treatment. We report two cases of IMT with genitourinary localization, being this entit's publications infrequent. Both presented with little symptomatology, leading to multiple differential diagnosis. The surgical treatment was chosen and pathologic result confirmed the diagnosis. CONCLUSION: This entity must be considered as a true malignant neoplasm with aggressive local behavior. The gold standard management is complete surgical resection, with low recurrence rate after it. A new oncological monitoring scheme is proposed, upon the lack of an active surveillance algorithm after treatment.

OBJETIVO: El tumor miofibroblástico inflamatorio (TMI) es una neoplasia con potencial biológico intermedio, infrecuente, con un pronóstico clínico impredecible y una tasa de recurrencia baja después de un tratamiento efectivo. Se presentan dos casos de diagnóstico de TMI con localización genitourinaria, siendo ésta de infrecuente publicación. Ambos se presentaron con escasa sintomatología, llevando a múltiples diagnósticos diferenciales. El tratamiento quirúrgico fue el de elección, confirmándose el diagnóstico con el resultado anatomopatológico. CONCLUSIÓN: Esta entidad debe ser considerada como una verdadera neoplasia maligna con comportamiento local agresivo. La resección quirúrgica completa es el gold-standard, con baja tasa de recurrencia posterior a la misma. Se propone un nuevo esquema de seguimiento oncológico, ante la falta de un algoritmo de vigilancia activa posterior al tratamiento
