A benign tumor of mature adipocytes within (intramuscular) or between (intermuscular) skeletal muscles.
Lipoma is the most common soft tissue tumor in the adulthood accounting for about one half of all soft tissue tumors (Myhre-Jensen 1981; Rydholm and Berg 1983). However, its real incidence may be underestimated. The frequency of lipoma seems to be higher in the obese population. Intramuscular/intermuscular lipoma accounts for less than 10% of all benign lipomas.
Intramuscular/intermuscular lipoma more frequently affects middle aged adults (usually between the fourth and sixth decades).
There is a male predominance.
Intramuscular/intermuscular lipoma usually affects the large muscles of the thigh, shoulder, arm, and trunk.
Simple excision is the recommended treatment.
Intramuscular/intermuscular lipoma is benign with no capacity to dedifferentiate or metastasize....
