"RB1 deletion"
"lack of MDM2 or CDK4 amplification"
"Immunohistochemistry stains can be variably positive for CD34, S100 and desmin and can show a loss of nuclear RB expression in the majority of cases. There is an absence of coexpression of MDM2 and CDK4, however, there can be weak expressions of either one of them 1-5."
"Atypical spindle cell/pleomorphic lipomatous tumours are characterised by a variable amount of atypical spindle cells adipocytes, lipoblasts and pleomorphic or multinucleated cells found in a fibrous and/or myxoid matrix 1-3."
"Immunohistochemistry stains can be variably positive for CD34, S100 and desmin and can show a loss of nuclear RB expression in the majority of cases. There is an absence of coexpression of MDM2 and CDK4, however, there can be weak expressions of either one of them 1-5."
"form, location and size"
"Immunohistochemistry stains can be variably positive for CD34, S100 and desmin and can show a loss of nuclear RB expression in the majority of cases. There is an absence of coexpression of MDM2 and CDK4, however, there can be weak expressions of either one of them 1-5."
"Atypical spindle cell/pleomorphic lipomatous tumours are benign lesions and have an excellent prognosis if they are completely excised. The local recurrence rate is about 10-15% 4. There is no known risk of metastases 1-3."
