Speculation of the pathogenesis of ED has led to a strong suggestion that recurrent frictional irritation in the region of the angle of the scapula and the thoracic wall yields an increase in propagation of fibroblastic
sarcoma (MIFS) is a rare soft tissue tumor first reported in 1998 by 3 independent investigators.
Desmoid-type fibromatosis, also known as aggressive fibromatosis or desmoid tumor, is a rare neoplasm of deep soft tissues that is histologically characterized by an infiltrative, low-grade fibroblastic
proliferation and clinically characterized by a tendency for local recurrence but no metastatic potential.
This hormonally responsive tumour is believed to arise from specialised mesenchymal cells of the pelvic-perineal region or from the multipotent perivascular progenitor cells, which often display variable myofibroblasts and fibroblastic
Diseases and conditions include Barrett esophagus, mesenchymal neoplasms such as gastrointestinal stromal tumors, schwannoma, benign fibroblastic
polyps, hereditary cancer syndromes, adenocarcinoma, intestinal metaplasia, and melanoma.
2,5 Immunohistochemical reactivity against S-100 and neuron-specific enolase is an essential tool to differentiate these tumors from spindle cell neoplasms of other origin (myofibroblastic tumors, tumors of muscle tissue origin, and fibroblastic
and myofibroblastic proliferation of the vulva (cyclist's nodule): A hitherto poorly described vulval lesion occurring in cyclists.
The odontogenic nature of the myxomas has been challenged by some authors because of the appearances, whilst consistent with odontogenic ectomesenchyme, could also represent a more primitive fibroblastic
or undifferentiated tissue.
The number of fibroblastic
cells had a tendency to decrease (Table I).
NF is a benign soft tissue lesion composed of tumorlike fibroblastic
and myofibroblastic proliferation.
Microscopically, polyp growth had fibroblastic
cell proliferation (whorls and interlacing bundles of fibroblastic
cells) and slight congestion which was suggestive of presence of benign growth in form of a unilateral nasal polyp.
and chondroblastic subtypes may have a slightly better prognosis compared to the other subtypes9.
