Lipomas
Symptoms
Lipomas are soft, slow-growing, fatty lumps located just beneath the skin. They are usually painless, round or oval, and move slightly under the skin when pressed. Most lipomas are less than 2 inches across but can grow larger over time. Common locations include the shoulders, back, arms, and thighs. Some patients may have multiple lipomas. They generally cause no symptoms but can occasionally become tender or painful if pressing on nearby nerves. Large or deep lipomas may cause cosmetic concern or discomfort. Growth tends to be gradual and stable.
Cause
Lipomas are composed of fat cells and are thought to arise from localized overgrowth of adipose tissue. The exact cause is unclear but genetics likely plays a significant role, especially in people with multiple lipomas (familial multiple lipomatosis). They are more common in middle-aged adults and are not related to body weight. Trauma to an area may sometimes trigger development, although this is not fully proven. Lipomas are benign and not cancerous. Rarely, deeper or rapidly growing lumps may represent liposarcoma and should be evaluated.
Treatment
Most lipomas do not require treatment unless they cause discomfort, impair movement, or are cosmetically concerning. Surgical excision is the most effective removal method and is typically performed under local anesthesia. Larger or deep lipomas may require imaging (e.g., ultrasound or MRI) prior to removal. Liposuction is sometimes used but is less effective for complete removal. Once excised, lipomas rarely return in the same location. There are no effective topical treatments. Biopsy may be performed if there’s concern about malignancy.
