Chondroid lipoma: multimodality imaging in a 9-year-old female

The Adipocerous Ossein- Chondroid Lipoma

“…Tumor magnitude extends up to 11 centimeters with a median diameter of up to 4 centimeters. Cut surface is lobulated, yellowish or grey/white with glistening areas [3,4]. On fine needle aspiration cytology, mature lipocytes and lipoblast-like cells are disseminated within a chondromyxoid matrix [3].…”

“…On fine needle aspiration cytology, mature lipocytes and lipoblast-like cells are disseminated within a chondromyxoid matrix [3]. On microscopy, the well circumscribed and lobulated tumor is composed of mature adipose tissue and lipoblast-like cells with an encompassing myxoid and chondroid matrix [3,4]. Tumefaction is composed of nests and cords of miniature to medium-sized, multi-vacuolated cells simulating lipoblasts, chondroblasts or cells of a hibernoma.…”

“…Foci of metaplastic bone may be exceptionally discerned [3,4]. The well limited, encapsulated neoplasm consists of mature lipoid cells amalgamated within the tumor perimeter admixed with disseminated chondroid cells [4].…”

“…Foci of metaplastic bone may be exceptionally discerned [3,4]. The well limited, encapsulated neoplasm consists of mature lipoid cells amalgamated within the tumor perimeter admixed with disseminated chondroid cells [4]. Generally, clusters, strands or sheets of vacuolated, eosinophilic cells imbued with glycogen and lipid droplets are observed.…”

“…Generally, clusters, strands or sheets of vacuolated, eosinophilic cells imbued with glycogen and lipid droplets are observed. Encompassing stroma is variable and composed of mature adipose tissue and a partially fibrinous or hyalinized, significantly myxoid matrix [3,4]. Neoplasm exhibits multi-vacuolated, eosinophilic cells configuring strands, nests and sheets variably admixed with mature adipocytes along with a circumscribing myxoid or chondroid -like stroma [3,4].…”
