抄録

Histologically, intramuscular lipoma is characterized by mature fat cells infiltrating into muscle fiber. The incidence of this tumor is high in the skeletal muscle of both the upper and lower extremities. However, the incidence is extremely low in the oral cavity.<BR>We describe an intramuscular lipoma occurring in the oral floor of a child. On presentation, a palpable painless fixed mass, measuring 30× 25mm was found in the right side of the oral floor. Extraoral examination revealed an elastic soft mass in the right submandibular region. Computed tomography showed a fat-like mass in the right side of the oral floor. The mass contained cord-like structures. The margin was unclear. During operation, an oval tumor was enucleated with the surrounding muscule. Microscopic examination showed that the tumor was not covered with a capsule. The stroma was composed of mature adipose cells surrounded and separated by irregular bundles of skeletal muscle fiber. There were no malignant findings, including lipoblast cells. During 7 years 6 months of following-up, neither tumor recurrence nor functional impairment has occurred.
