Lipoma-like lipoblastoma arising from the femoral vein

Lipoblastomas are rare benign mesenchymal tumors that resemble embryonal developing white fat. They typically occur in infants and children younger than 3 years of age. They are occasionally observed in older children and rarely in adults [1, 2]. Lipoblastoma consists of irregular, small, lobulated tissue composed of a variable number of lipoblasts in different stages of development, including monovacuolated and multivacuolated lipoblasts, stellate or spindle-shaped mesenchymal cells, a plexiform capillary network, a myxoid matrix, and immature and mature adipocytes separated by fibrous septa.
