Abstract

Uterine mullerian adenosarcoma (MA) is a rare biphasic tumour that accounts for less than 0.5% of uterine neoplasms. The age range of presentation is wide, with the median age in the 5th decade of life. It usually has a good prognosis; however, it worsens when it presents with sarcomatous overgrowth, heterologous elements or infiltrates the myometrium.

We report the case of a 63-year-old woman presenting with abnormal vaginal bleeding and a sensation of solid material coming out of the cervical canal who was diagnosed with mullerian adenosarcoma with sarcomatous overgrowth (MASO) and presence of heterologous elements after performing a mass biopsy and subsequent hysterectomy.

We reviewed the literature, focusing especially on the differential diagnoses to be evaluated, as well as the differences in prognosis and treatment according to whether or not they present histologic features of poor prognosis.

Resumen

El adenosarcoma mülleriano (AM) de útero es un raro tumor bifásico que representa menos del 0,5% de las neoplasias de útero. La edad de presentación es amplia, estando la mediana de la edad en la 5.ª década de vida. Normalmente tiene un buen pronóstico; sin embargo, empeora cuando se presenta con sobrecrecimiento sarcomatoso, elementos heterólogos o infiltra el miometrio.

Comunicamos el caso de una mujer de 63 años, con sangrado vaginal anómalo y una sensación de salida de material sólido por el canal cervical. Se le diagnosticó adenosarcoma mülleriano con sobrecrecimiento sarcomatoso (AMSS) y presencia de elementos heterólogos después de realizar una biopsia de masa y posterior histerectomía.

Realizamos una revisión bibliográfica, centrándonos especialmente en los diagnósticos diferenciales a evaluar, así como en las diferencias en el pronóstico y en el tratamiento según si presentaban características histológicas de mal pronóstico o no.
