Desmoid tumors are locally aggressive fibroproliferative neoplasms that can lead to pain and dysfunction due to compression of nerves and surrounding structures. Desmoid tumors often progress through medical therapy, and there is frequently a delay of multiple months before radiation can provide symptomatic relief. To achieve more rapid symptomatic relief and tumor regression for unresectable d...

Desmoid tumors are rare, soft tissue tumors with no known capacity for metastasis. Although considered a benign lesion, desmoids can be locally aggressive and cause significant morbidity due to mass effect on adjacent structures and organs. Sites of involvement generally are the extremities, trunk, abdominal wall, and the intraabdominal region. Risk factors include induced situations such as hi...

A lipoma is a common benign tumor of mesenchymal origin that can arise in any location where fat is normally present, with incidence of approximately 16% of all mesenchymal tumors. However, submuscular lipomas under the pectoralis major muscle are rare. And, because lipomas tend to be small, large lipomas are specifically called ‘giant lipoma.’ Giant lipoma is defined as a lipoma that is greate...

We herein report the case of a rapidly progressive sporadic mesenteric desmoid tumor (DT). A 62-year-old woman presented with a 4-cm-diameter palpable mass in the left supraumbilical area. The mass showed an ill-defined margin with heterogeneous delayed enhancement on computed tomography and heterogeneous high intensity on T2-weighted magnetic resonance imaging. Sixteen months after the initial...

Desmoid tumors (DTs) are a group of rare and benign soft tissue tumors that result from monoclonal proliferation of well-differentiated fibroblasts. Since DTs tend to infiltrate and compress adjacent structures, the location of DTs is one of the most crucial factors for determining the severity of the disease. Furthermore, DTs can further complicate the clinical course of patients when the grow...

Extraskeletal mesenchymal chondrosarcoma (EMCS) is a rare malignant soft tissue tumor of chondroprogenitor cell origin. Originally, it was restricted to the bone only but that no longer case. Recent literature reports 20–33% these tumors occur at extraskeletal sites. We report one such case, in which involved anterior abdominal wall muscles and also had large intra- mass covered part peritoneal...
