Radiological-pathological correlation in lipoblastoma and lipoblastomatosis

Mediastinal lipoblastoma causing diaphragmatic eventration: a case report and review of the literature

Lipoblastomatous tumors are quite rare neoplasms derived from embryonic white fatty tissues. The majority is seen in infancy and early childhood. Generally they arise in extremities. Here, we present a 12-month-old female infant presenting with a mediastinal and cervical mass, showing left diaphragmatic eventration. We reviewed these cases and discussed clinical manifestations, radiologic, and histopathologic findings and treatment of these tumors.

Giant mesenteric lipoblastoma in a 4-year-old child

Lipoblastoma is a rare benign neoplasm of embryonal fat that occurs typically in infancy and childhood. An unusual case of a giant mesenteric lipoblastoma in a 4-year-old child is presented. The lipoblastoma was completely removed. Histopathologic examination confirmed the diagnosis of mesenteric lipoblastoma. Observation of the patient for 4 months postoperatively showed no evidence of recurrence.

Imaging of the unusual pediatric 'blastomas'

‘Blastomas’ are tumors virtually unique to childhood. Controversy surrounds their nomenclature and there is no globally accepted classification. They are thought to arise from immature, primitive tissues that present persistent embryonal elements on histology, affect a younger pediatric population and are usually malignant. The ‘commoner’ blastomas (neuroblastoma, nephroblastoma, hepatoblastoma, medulloblastoma) account for approximately 25% of solid tumors in the pediatric age range. We present examples of the more unusual blastematous pediatric tumors (lipoblastoma, osteoblastoma, chondroblastoma, hemangioblastoma, gonadoblastoma, sialoblastoma, pleuropulmonary blastoma, pancreatoblastoma, pineoblastoma, and medullomyoblastoma) that were recorded in our institution. Although these rare types of blastomas individually account for <1% of pediatric malignancies, collectively they may be responsible for up to 5% of pediatric tumors in a given population of young children. Imaging is often non-specific but plays an important role in their identification, management and follow-up. Some characteristic imaging features at diagnosis, encountered in cases diagnosed and treated in our institution, are described and reviewed.

Unusual breast enlargement in an infant: a case of breast lipoblastoma

We report the first case of lipoblastoma of the breast, diagnosed postoperatively in a 13-month-old infant. We discuss the management of this case, conditioned by peculiar localization, emphasizing the differential diagnosis of other causes of breast enlargement. Surgeons should know this condition and its implications, while dealing with developing breasts.
