Shoulder Lipoblastoma in a 2-Year-Old Boy Case Report and Literature Review.

Introduction: Lipoblastoma is a rare mesenchymal benign tumor of the white fat cells that affect mostly infants and children below 3 years old. MLipoblastoma can be found in various locations in the body, however, it is usually located in the extremities, lower extremities in particular. Case Report: We describe a case of a 2-year-old Middle Eastern boy who has a rare lipoblastoma of his left shoulder that is unusual. Conclusion: The most common presentation of this rare tumor is a child younger than 3 years old with asymptomatic, painless, rapidly growing mass that warrants an appropriate index of suspicion to avoid misdiagnosis. Complete excision with free margins is fundamental as a definitive treatment of this benign tumor to eradicate any chance of recurrence or any possible complications including compressive symptoms, magnetic resonance imaging may be helpful in identifying the nature of the mass, however, the diagnosis confirmed postoperatively through histological and cytogenetic analysis. Chromosomal analysis is quite helpful in differentiating lipoblastoma from liposarcoma because they have different management and prognosis.
