Rhabdomyosarcoma with Pseudolipoblasts Arising in Ovarian Carcinosarcoma: A Distinctive Postchemotherapy Morphologic Variant Mimicking Pleomorphic Liposarcoma
Figure 2
(a) Many of the multivacuolated cells show strong cytoplasmic desmin expression. (b) A smaller number of multivacuolated cells show strong nuclear myogenin expression. (c) Scattered cells are strongly positive for S100 protein. (d) The multivacuolated cells are negative for AE1/AE3, in contrast to the malignant epithelial elements (top left of field).
