Soft-tissue sarcomas occurring in the abdomen and pelvis are an uncommon but
important group of malignancies. Recent changes to the World Health Organization
classification of soft-tissue tumors include the movement of gastrointestinal
stromal tumors (GISTs) into the soft-tissue tumor classification. GIST is the
most common intraperitoneal sarcoma. Liposarcoma is the most common
retroperitoneal sarcoma, and leiomyosarcoma is the second most common. GIST,
liposarcoma, and leiomyosarcoma account for the majority of sarcomas encountered
in the abdomen and pelvis and are discussed in part 1 of this article.
Undifferentiated pleomorphic sarcoma (previously called malignant fibrous
histiocytoma), dermatofibrosarcoma protuberans, solitary fibrous tumor, malignant
peripheral nerve sheath tumor, rhabdomyosarcoma, extraskeletal chondro-osseous
sarcomas, vascular sarcomas, and sarcomas of uncertain differentiation uncommonly
arise in the abdomen and pelvis and the abdominal wall. Although these lesions
are rare sarcomas and their imaging features overlap, familiarity with the
locations where they occur and their imaging features is important so they can be
diagnosed accurately. The anatomic location and clinical history are important
factors in the differential diagnosis of these lesions because metastasis,
more-common sarcomas, borderline fibroblastic proliferations (such as desmoid
tumors), and endometriosis have imaging findings that overlap with those of these
uncommon sarcomas. In this article, the clinical, pathologic, and imaging
findings of uncommon soft-tissue sarcomas of the abdomen and pelvis and the
abdominal wall are reviewed, with an emphasis on their differential diagnosis.
