Soft or connective tissue sarcoma

Soft or connective tissue sarcoma encompasses a heterogeneous group of rare malignant tumors arising from extraskeletal mesenchymal tissues, including muscle, adipose tissue, fibrous tissue, peripheral nerves, blood vessels, and deep fascial structures Pathophysiologically, they originate from mesenchymal progenitor cells and are characterized by expansive local growth—often forming a false fibrous capsule with microscopic infiltrative extensions—alongside a tendency for local recurrence and hem...

These neoplasms can develop in individuals of any age and occur throughout the body, most commonly involving the extremities, retroperitoneum, trunk, and head and neck

Clinically, they typically present as painless, progressively enlarging soft-tissue masses, though retroperitoneal or deep visceral lesions may remain clinically silent until they cause compression of adjacent structures
