Rapid-growing Tumor of the Cheek Mimicking a Malignant Tumor: Lipoblastoma of Infancy

In this case report, we describe a 5-month-old girl with a rapid-growing mass of the lower lip extending to the buccal cheek. After surgical interference, the diagnosis lipoblastoma was made. Dealing with a fast-growing tumor in an infant, lipoblastic tumors belong in the differential diagnosis, however, a malignant process cannot be excluded. Rapid-growing lipoblastoma of infancy is a very rare benign tumor of embryonic white fatty cells. Magnetic resonance imaging might help with the diagnosis and often shows a lesion composed mostly, but not entirely, of fat. In this case report, we want to draw attention to the problems with diagnosis and therapeutic management of children with lipoblastoma.
