Abstract
ABSTRACTLipoblastoma and lipoblastomatosis are rare benign soft-tissue tumoral lesions resembling fetal adipose tissue. A total of 16 cases of lipoblastoma of the neck were reported in the literature, and only 3 were described in the posterior side of the neck. Hibernoma is a rare benign adipose tumor composed of brown fat cells and only about ten cases occurring in the cervical area have been reported. We reported two rare cases of adipose tissue tumors. The first case was a male infant aged 12 months who had a cervical mass on the posterior side of the neck. He underwent a complete resection of the lesion and the pathologic study revealed lipoblastomatosis. The second case was a 36-year-old man with an anterior cervical mass, which moved with swallowing. A resection was made and the histological analysis showed hibernoma.
Highlights
Lipoblastomas and their diffuse, multicentric and infiltrative forms, the lipoblastomatosis, are rare benign soft tissue tumors that resemble the fetal adipose tissue
Adipose tumors comprise about 6% of soft tissue neoplasms and are developed in the first two decades of life
Lipoblastoma is a benign tumor of embryonic fat cells(2) that occurs mainly before the age of 3 years, are more prevalent in men(1), and arise primarily in the trunk and extremities
Summary
Lipoblastomas and their diffuse, multicentric and infiltrative forms, the lipoblastomatosis, are rare benign soft tissue tumors that resemble the fetal adipose tissue. Lipoblastoma is a benign tumor of embryonic fat cells(2) that occurs mainly before the age of 3 years, are more prevalent in men(1), and arise primarily in the trunk and extremities. Cervical hibernoma is a benign tumor that could be considered a differential diagnosis and is opposed to lipoblastoma(2), and occurs mainly in adults(3). CASE REPORTS Case 1 Male infant aged 12 months who had a cervical mass on the posterior side of the neck measuring 60x40mm.
