Fibromatosis and/or desmoid tumors which constitute less than 1% of all neoplasms and 3.0% of all soft-tissue tumors are pathologically benign proliferations of the fibroblasts but are locally aggressive with infiltrative type of growth and tendency toward recurrence. Bilateral symmetrical perirenal involvement has been described in many conditions which can be renal, subcapsular, or perirenal ...

aggressive fibromatosis or desmoid tumors, histologically indicated by small bundles of spindle cells in a fibrous background, are uncommon benign tumors without metastasis. they are recurrent and aggressive and their recurrence and severity is exacerbated following surgical operation. based on previous reports, these tumors rarely present as intra-abdominal abscesses. herein, a 54-year-old wom...

Desmoid tumours are benign monoclonal myofibroblastic neoplasms arising from musculoaponeurotic stromal tissue. They infiltrate local tissue but have no known metastatic potential. The management of desmoid tumours is complicated by their unpredictable nature and rarity, which makes study into their behaviour, and therefore treatment, a challenge. We present a case of intra-abdominal desmoid tu...

Desmoid tumors represent a particular type of fibromatosis. The common sites for extra-abdominal desmoid tumors, known as aggressive fibromatosis, are the shoulder, chest wall, and thigh. Desmiod tumors are rare at facet joints of the spine. We describe a patient with a desmoid tumor of a lumbar facet joint.

Mammary fibromatosis is an uncommon, benign tumor of the breast. It is locally aggressive and has a high rate of recurrence. Its clinical presentation and imaging results always call for suspicion of malignancy. Here we describe a case of mammary fibromatosis with clinical manifestation, radiographic and pathologic results, and imaging findings from ultrasound elastography.
