ABSTRACT

Las lesiones lipomatosas uterinas son una variante poco frecuente de los tumores mesenquimales benignos. Se dividen en lipomas puros y lesiones lipomatosas (difusas o focales) en el seno de un leiomioma. Presentamos el caso de una mujer de 70 años con histerectomía simple tras el diagnóstico ecográfico de «mioma gigante». Macroscópicamente la lesión correspondía a una formación lipomatosa de 13,8cm de eje máximo e histológicamente estaba constituida por células adiposas maduras, sin septos, y con cambios atróficos y traumáticos, positivas para S100 y vimentina y negativas para MDM2 y CDK4 por inmunohistoquímica e hibridación fluorescente in situ. Focalmente se identificaban áreas de degeneración mixoide y no se observaba necrosis ni hemorragia. El estudio ultraestructural fue congruente con una proliferación celular con diferenciación adiposa (AU)


Uterine fatty lesions are a rare variant of benign mesenchymal tumours. They are divided into pure and lipomatous lesions (diffuse or focal) within a leiomyoma. We report the case of a 70 year old woman who underwent a simple hysterectomy after an ultrasound diagnosis of «giant leyomioma». Macroscopically the lesion corresponded to a lipomatous formation of 13.8cm maximum diametre. Histologically the lesion consisted of mature adipose cells without septa and traumatic and atrophic changes. There was focal myxoid degeneration, but necrosis and hemorrhage were not observed. The cells were S100 and vimentin positive on immunochemistry. MDM2 and CDK4 were negative by immunochemistry and fluorescence in situ hybridization. The ultrastructural study was consistent with a cell proliferation with adipose differentiation (AU)
