Infiltrative angiolipoma of the neck.

Lipomas are the most common mesenchymal tumors of the body. They can occur in any soft tissue ranging from subcutaneous fat to the parosteal areas adjacent to bone. They are usually asymptomatic masses easily diagnosed on radiological imaging1. Angiolipoma is a variant of lipoma with proliferation of its vascular component. These tumors occur on the trunk and extremities of young adults with the forearm being the most common site of involvement. Documented sites of occurrence in the head and neck region include cheek, palate, neck, jaw, nose, eyelid, parotid, tongue, paranasal sinuses and parapharynx. Only 4 cases have been described in the neck, with 75% of these being infiltrative2. We would like to present the fifth case of infiltrative angiolipoma of the neck.
