Benign lipoblastomatosis is a tumor consisting of fetal-embryonal adipocytes, frequently confused with a liposarcoma, affecting exclusively infants and young children, with approximately 90% of cases occurring before 3 years of age.[2][3]: 626 The term lipoblastomatosis was first used by Vellios et al. in 1958, at which point the tumor became generally accepted as a distinctive entity.[4][5] Today Diffuse lipoblastoma is the preferred term for lipoblastomatosis.[6][7] The tumor is rare, accounting for less than 1% of all childhood neoplasm,[8] and it has been found to be more common in males than females.[9][8] It often presents as an asymptomatic rapidly enlarging mass, occurring more often in the soft tissues of the extremities.[8][9]
Signs and symptoms[edit]
Although they have also been reported in the head and neck, shoulder, groin, axilla, back, and abdominal cavity, these tumors typically manifest in the extremities.[10] Although it is normally painless, it may cause symptoms such as vomiting, stomach pain, paralysis, or incontinence depending on where the mass is anatomically.[11][12]
Causes[edit]
Lipoblastomatosis most likely results from new adipose tissue lobules and lipoblasts proliferating throughout the neonatal period.[10]
Diagnosis[edit]
Although imaging modalities like magnetic resonance imaging (MRI) and computed tomography (CT) can be useful, histology confirmation is necessary for an accurate diagnosis.[10]
Treatment[edit]
Prompt surgical resection is the advised course of treatment for lipoblastomatosis, particularly if the mass is close to any important organs.[10]
