Caso clínico: paciente femenina de 53 años de edad, originaria y residente de Tabasco, con antecedente de liposarcoma pleomórfico de mediastino anterior. Case report of a retroperitoneal liposarcoma pleomorfico with calcification in diagnosed in our hospital. We comment on its clinical characteristics, diagnostic. Diagnostic utility of p16, CDK4, and MDM2 as an immunohistochemical panel in distinguishing well-differentiated and dedifferentiated liposarcomas from other.

Soft tissue Adipose tissue Pleomorphic liposarcoma Author: J Exp Clin Cancer Res ; Multidisciplinary approach to giant paratesticular liposarcoma. Storiform pattern cells emanate from a central focusirregular fascicles, variable cellularity Pleomorphic and bizarre tumor cells with foamy cytoplasm and marked atypia, in background of inflamed collagenous stroma May represent end stage of various sarcomas with common morphologic features of pleomorphism and storiform growth pattern Multinucleated giant cells may be seen; if prominent, classify as MFH-giant cell Numerous mitotic figures, including atypical forms Rarely metaplastic not neoplastic bone or cartilage.

Mass and pericardium both revealed well differentiated liposarcoma which was CDK 4 positive and ALK rearrangement was not pleoorfico.
