giant congenital sialolipoma of parotid gland with parapharyngeal extension

Introduction: sialolipoma is an extremely rare salivary gland tumor characterized by a well circumscribed mass composed of glandular tissue and mature adipose elements. herein our aim was to present the fifth case of congenital sialolipoma, which was firstly followed up as a parotid gland hemangioma, and underline the fact that sialolipomas should be kept in mind in the differential diagnosis of congenital parotid gland masses.   case report: a 10-month old male presented with a left-sided huge neck mass which progressed after birth. radiologic examination revealed a tumor originating from the parotid gland filling the parapharyngeal space. histopathologic examination of an incisional biopsy was consistent with sialolipoma. a total parotidectomy with preservation of the facial nerve was performed at the age of 1 year. the postoperative recovery was uneventful with normal facial nerve function. there was no recurrence at the 24-month follow-up.conclusion: although it is a very rare benign tumor, congenital sialolipoma should be kept in mind in the differential diagnosis of congenital parotid mass.
