ABSTRACT
O lipoblastoma é um tumor mesenquimal raro, composto de lipoblastos que continuam sua proliferação após o período pós-natal e que acometem, predominantemente, a população pediátrica. Apresenta prognóstico excelente, apesar do potencial de invasão local e do crescimento rápido. Os autores relatam o caso de uma paciente pediátrica portadora de volumosa lesão em antebraço direito, ocasionando importante comprometimento funcional do membro acometido. Aspectos relevantes no diagnóstico diferencial e manejo são discutidos neste trabalho, visto tratar-se de lesão com potencial risco incapacitante futuro, caso não manejada corretamente.
Lipoblastoma is a rare mesenchymal tumor occurring primarily in pediatric patients and formed by lipoblasts that proliferate after the postnatal period. Despite its potential for local invasion and rapid growth, its prognosis is excellent. In this study, we report the case of a pediatric patient with a ponderous lesion in the right forearm that caused considerable functional impairment of the affected limb. We also discuss the relevant aspects concerning the differential diagnosis and management of the disease, as it has the potential to cause incapacity without proper treatment.

Currently the research on adipose tissue has yielded same insights of itïs function. On the embrionary state the differentiation between white adipose tissue and brown adipose tissue and brown adipose tissue signals different functions. The presence of multiple receptors and actions define itïs autocrine, paracline and endocrine roles
