Eight Cases of Deep Lipoma of the Forehead / 대한피부과학회지

ABSTRACT

Lipomas are the most common benign mesenchymal tumors composed of mature fat cells. They can be classified into superficial lipoma (subcutaneous lipoma) or deep lipoma (subfascial lipoma) depending on the depth they develop. The latter is quite rare and tends to be less circumscribed and relatively fixed compared to the superficial ones. Therefore, it is initially misdiagnosed as other superficial lesions, and pre-operative awareness of deep tumors is important to differentiate them from other superficial lesions. Futhermore, the removal of the tumor also requires a detailed knowledge of the anatomy of the forehead, plus more sophisticated surgical skills so as not to damage important structures in the forehead such as vessels and nerves. Herein, we report 8 cases of deep lipoma on the forehead, demonstrating that it is not as rare as reported.
