The differential diagnosis of cheek masses can include any component t
hat arises from the region or that metastasizes to it. Given the array
of potential anomalies that can present in this area and their clinic
al implications, an early diagnosis is essential. This report describe
s a condition observed in a series of patients with abnormal positioni
ng of the buccal fat pad as the cause of their cheek masses. In the ap
propriate setting, a soft, nontender, walnut-sized mass that reduces i
nto the buccal space is pathognomonic for the syndrome referred to as
pseudoherniation of the buccal fat pad. Magnetic resonance imaging can
also be used to evaluate the region. Treatment is accomplished by exc
ision or repair of the fascial defect.
