What is Proliferative fasciitis?
Proliferative fasciitis is a subcutaneous or fascial reactive process that contains fibroblasts and myofibroblasts. It is identical to proliferative myositis except that it arises in an extramuscular location. This disease affects primarily middle-aged and older individuals and is rare in children.
What is ischemic fasciitis?
Ischemic fasciitis is a rare pseudosarcomatous proliferation of atypical fibroblasts described to be located over bony protuberances and said to develop most often in immobile elderly or debilitated patients.
What is Fibromyxoid sarcoma?
FY-broh-MIK-soyd sar-KOH-muh) A rare, slow-growing type of cancer that usually forms in the deep soft tissues of the legs or trunk (chest and abdomen). The cancer may come back many years after treatment and spread to the lungs and the lining of the wall of the chest cavity.
How is nodular fasciitis diagnosed?
Imaging by sonogram, MRI scan, or CT scan can help characterize features of nodular fasciitis. FNAC followed by an analysis of tissue histology can help make a definitive diagnosis. Sometimes the diagnosis isn’t confirmed until the tumor is surgically removed.
Where does nodular fasciitis occur?
Nodular fasciitis (NF) is a benign, soft tissue tumor composed of myofibroblasts (i.e. immature cells that contain features of myocytes and fibroblasts) that typically occurs in subcutaneous tissue (i.e. lowermost layer of the skin), fascia (i.e. band of connective tissue just beneath the skin), and/or muscles.
Is nodular fasciitis painful?
Nodular fasciitis is a benign fibroblastic lesion that was historically misdiagnosed as a malignant neoplasm. Patients present with pain and swelling of relatively brief duration. The clinical presentation is suggestive of an aggressive lesion, usually occurring in muscle fascia.
Can nodular fasciitis be misdiagnosed?
Nodular fasciitis is a reactive proliferation of fibroblasts/myofibroblasts in the fascia and subcutaneous tissue. Histological examination sometimes reveals cellular heterotypia and polymorphism. Therefore, nodular fasciitis is often misdiagnosed as soft tissue sarcoma.
What are myxoid features?
Myxoid matrix has very high water content, which is responsible for its hypoechoic appearance on ultrasound, low attenuation on CT, and extremely low and high signal intensity on T1- and T2-weighted MRI, respectively. MRI is the imaging modality of choice for the evaluation of these tumors [3].
