Liposarcome de la loge rénale: à propos de deux cas avec revue de la littérature

Abstract: Les sarcomes rétropéritonéaux sont des tumeurs rares et hétérogènes. Nous en présentons deux cas localisés à la loge rénale avec revue de la littérature dans le but d’insister sur les particularités anatomiques et chirurgicales de cette localisation, et sur ses éventuels retentissements pronostiques. Le premier cas de tumeur a été rapporté chez une patiente de 45 ans localisée au niveau de la loge rénale gauche, dont le diagnostic de liposarcome de type myxoïde a été posé sur l’examen anatomo-pathologique de l… Show more

“…Well-differentiated liposarcomas (WDLPS) are locally aggressive tumors with low metastatic potential, accounting for 40–45% of all liposarcomas. 11 From a histological perspective, it can be categorized into three distinct subgroups that can co-exist simultaneously within the same tumor: well-differentiated “Lipoma-like,” sclerosing and inflammatory LPS. 11 Dedifferentiated liposarcoma (DLPS) is an atypical lipomatous tumor arising de novo 90% of the time and 10% develop in recurrences.…”

“…At the ultimate evolution, abdominal and pelvic complaints can motivate the consultation (heaviness, palpable mass or even pain). Associated urological or digestive symptoms are rare [ 5 ]. In our case, the reason for consultation was the isolated painless abdominal mass.…”
