A case of @entity18391 simulating a @entity2695 in a male @entity1 is reported, to alert pediatricians to this rare @entity5 and to increase the index of suspicion in @entity2695 . A 2-month-old male @entity1 developed a protruding forehead mass with increased vascularity. It demonstrated progressive and accelerated growth over the subsequent 6 months, unresponsive to @entity134 therapy. A magnetic resonance imaging scan supported the diagnosis of @entity2695 because of the hypervascular nature of the lesion. Surgical excision was performed because of @entity227 . Pathologic examination of the specimen was consistent with a very primitive @entity18391 . This @entity5 is a rare, benign lesion of immature fat cells that is found almost exclusively in the pediatric population. @entity18391 are more common in males than females and frequently present as asymptomatic, rapidly enlarging, soft lobular masses on the extremities. Complete surgical excision is the definitive treatment. In the vast majority of reported cases, however, the preoperative diagnosis was incorrect, underscoring the diagnostic dilemma presented by these rare @entity5 .
