Abstract Background Infantile Fibrosarcoma is a rare soft tissue tumor in infants and children mostly located in extremities. An infantile and adult form has similar histopathological patterns but survival prognosis is much better in infantile form. Recurrence of infantile fibrosarcoma is common but the rates of metastasis are less than 10 percent in children younger than five Years and 50 p...

objective: sarcomas are neoplasms of mesenchymal (stem cell) origin and are rare skin diseases of cats and may occur anywhere on the cat body.the main etiologies of soft tissue sarcomas are feline sarcoma virus induced sarcomas, vaccine site sarcomas, trauma, inflammation and radiation. methods: in march 2014, a three years old male domestic shorthair cat were referred to a private veterinary c...

Fibrosarcoma of the oral and maxillofacial region is a rare entity with poor prognosis. Most common sites are the extremities, with only one percent of fibrosarcoma arising in the head and neck area. Oral fibrosarcoma are locally infiltrative and destructive, spreads by haematogenous dissemination. The positive immunostaining for vimentin, together with negativity for muscular immunomarkers hel...

Fibrosarcoma is a malignant tumour arising from fibroblasts. Several variants have been described and these prove to be diagnostic challenge owing its many mimics, thus often requiring ancillary testing such as immunohistochemistry. The sclerosing epithelioid variant poorly recognised entity that poses therapeutic dilemma. This case of Fibrosarcoma-sclerosing reported in 62-year-old male who pr...

Objectives: Odontogenic tumors occupy an important position among head and neck tumors. Although, rarely encountered in medical practice but they considered increasingly challenging lesions for the clinicians due to their overlapping clinical histopathological features. This study was designed determine relative frequency of central odontogenic Iraqi population by utilizing 2022 WHO tumor class...

while carcinoma of breast is common condition, stromal sarcomas are rare tumors of breast, amongst which fibrosarcoma accounts for 16% of cases. only a few case reports are available in the international literature. we report a case of fibrosarcoma of breast, which presented as an un-encapsulated mass in the right breast of a 60-year-old female. this case was diagnosed after exclusion of all po...

Cancerous human fibrosarcoma cells undergo collective migration at the edge of their colony by combining mesoscale self-organization and intrinsic handedness, showing how physical interactions alone can lead to biological functionality.
