Benign Soft Tissue Tumors

Lipomas are the most common benign neoplasm and usually arise in subcutaneous tissue. The trunk and proximal limbs are the most frequent sites. Although deep-seated benign lipomas do occur in the mediastinum or retroperitoneum, seemingly mature fatty neoplasms in the retroperitoneum should be considered well-differentiated (WD) liposarcoma. Most lipomas are solitary, soft, and painless and grow slowly; 2–3 % of patients have multiple lesions that are occasionally seen in a familial pattern.
