Pearls and Pitfalls

Lipomas are common benign breast masses. The average age of presentation is in the late 40s or early 50s. Generally, these tumors are unilateral. In 3% of cases, bilateral lipomas are present. Histologically, these tumors are composed of mature lipocytes surrounded by a capsule.
