title: Subcutaneous Midline Nasal Mass in an Infant due to an Intramuscular Lipoma.
abstract: Intramuscular lipomas are rare, benign, mesenchymal tumors occurring deep in the fascia, typically involving large muscle groups in adults. We report a case of an intramuscular lipoma occurring as a subcutaneous midline nasal mass in a 3-month-old infant. The differential diagnosis of a midline mass on the glabella of an infant is important and should include developmental anomalies such as nasal glioma, nasal dermoid cyst, and encephalocele, so neuroimaging is an essential first step in evaluating these lesions to exclude intracranial extension.
