Intramuscular Lipoma of Cheek: A Rarity

S Jayachandran and Koijam Sashikumar Singh

Intramuscular lipomas are uncommon benign mesenchymal tumors which infiltrate skeletal muscle. It is very rarely encountered in head and neck region and often located in limbs. A consistent feature is infiltration with dissociation of the surrounding muscle fibers which makes it difficult to distinguish from well-differentiated liposarcomas. Its recurrence is very high. Imaging such as CT, MRI and ultrasonography gives valuable diagnostic information which seldom requires histopathology for diagnosing these lesions. Here, we report a case of an intramuscular lipoma of the masseter muscle in a 50-year-old male patient who presented with a growing mass in the left cheek. The radiographic imaging features are also discussed.
