SPINDLE CELL/SCLEROSING RHABDOMYOSARCOMA Figure 1-121 SPINDLE CELL/SCLEROSING RHABDOMYOSARCOMA A,B: Eosinophilic tumor cells with mildly pleomorphic nuclei are arranged as alternating fascicles, resembling leiomyosarcoma. C,D: Desmin is strongly positive (C), and myogenin is typically focal (D). More about this image found in SPINDLE CELL/SCLEROSING RHABDOMYOSARCOMA A,B: Eosinophilic tumor cells wit...

SCLEROSING ODONTOGENIC CARCINOMA Figure 5-21 SCLEROSING ODONTOGENIC CARCINOMA Highly destructive osteolytic lesion of the anterior maxilla. Only one other reported case has root resorption. More about this image found in SCLEROSING ODONTOGENIC CARCINOMA Highly destructive osteolytic lesion of t...

SCLEROSING ODONTOGENIC CARCINOMA Figure 5-24 SCLEROSING ODONTOGENIC CARCINOMA Cytologically bland tumor cells with cytoplasmic clearing in a densely sclerotic stroma. More about this image found in SCLEROSING ODONTOGENIC CARCINOMA Cytologically bland tumor cells with cyto...

SCLEROSING PARAGANGLIOMA Figure 7-9 SCLEROSING PARAGANGLIOMA Some paragangliomas have dense, collagenized stroma relative to the amount of actual tumor cells. This can lead to diagnostic challenges given the similarity to other lesions. The stroma obscures the typical nested pattern More about this image found in SCLEROSING PARAGANGLIOMA Some paragangliomas have dense, collagenized stro...

CAROTID BODY SCLEROSING PARAGANGLIOMA Figure 9-19 CAROTID BODY SCLEROSING PARAGANGLIOMA A: Sclerosing paragangliomas have been reported as a distinct entity that can mimic infiltrating carcinoma. This sharply circumscribed example shows extensive sclerosis, which is very dense at top right. B More about this image found in CAROTID BODY SCLEROSING PARAGANGLIOMA A: Sclerosing paragangliomas have be...

LATE STAGE OF SUBACUTE SCLEROSING PANENCEPHALITIS (SSPE) Figure 3-22 LATE STAGE OF SUBACUTE SCLEROSING PANENCEPHALITIS (SSPE) Whole mount section of autopsy brain shows marked atrophy, secondary ventricular enlargement (hydrocephalus ex vacuo), and mild meningeal fibrosis. Note the gaping space More about this image found in LATE STAGE OF SUBACUTE SCLEROSING PANENCEPHALITIS (SSPE) Whole mount secti...

SUBACUTE SCLEROSING PANENCEPHALITIS Figure 3-23 SUBACUTE SCLEROSING PANENCEPHALITIS Whole mount autopsy brain section changes several years after clinical onset of symptoms, showing the small size of the brainstem at the level of the medulla (A), compared to medulla from an age-matched control More about this image found in SUBACUTE SCLEROSING PANENCEPHALITIS Whole mount autopsy brain section chan...

SUBACUTE SCLEROSING PANENCEPHALITIS Figure 3-24 SUBACUTE SCLEROSING PANENCEPHALITIS In late stages of disease, there is meningeal fibrosis and usually scanty mononuclear cells. More about this image found in SUBACUTE SCLEROSING PANENCEPHALITIS In late stages of disease, there is me...

SUBACUTE SCLEROSING PANENCEPHALITIS Figure 3-25 SUBACUTE SCLEROSING PANENCEPHALITIS At autopsy, perivascular mononuclear cell cuffing (without vasculitis) is often more conspicuous than meningeal inflammation. Violaceous smudged viral inclusions can be found within neuronal nuclei (arrow More about this image found in SUBACUTE SCLEROSING PANENCEPHALITIS At autopsy, perivascular mononuclear c...
