Summary

• Benign tumours composed of adipose tissue.
• Can occur in any area of the body, although they are most frequently found on the trunk or proximal limbs. Most commonly found in subcutaneous tissues.
• Rare sites include GI tract, adrenal glands, parotid glands, parapharyngeal space, breast, mediastinum, pleura, airways, heart, superior vena cava, brain, and intraspinal areas.
• Cutaneous lipomas are usually soft, mobile, and superficial.
• No malignant potential. However, the differential diagnosis includes liposarcomas, which are malignant, so this must always be carefully considered.
• Surgical resection is indicated for symptomatic relief, pathological confirmation, or cosmetic reasons, or if there is an increase in size.
