Chondroid Lipoma : Microscopic Features

Comments:
Microscopic Features (continued from the previous image): The rounded tumor cells are arranged in sheets, nests and cords in a background of myxoid or hyalinized chondroid stroma. The presence of lacuna-like spaces around small tumor cells in a myxohyaline background creates resemblance to cartilage.

There is variable amounts of mature fat admixed with uni- or multivacuolated lipoblasts and hibernoma-like cells with eosinophilic granular cytoplasm. The cells have uniform oval or bean-shaped nuclei with even chromatin and inconspicuous nucleoli. There is no pleomorphism and mitotic activity is low.
