We used immunostaining for vimentin (clone V9, Dako, 1:50) and alpha smooth muscle actin (clone 1A4, Dako, 1:100), revealing intense and diffuse cytoplasmic stainingof the neoplastic cells for both vimentin (Figure 1D) and alpha smooth muscle actin (Figure 1E).
(15) The neoplastic cells are large (usually >20 [micro]m) and are round to oval with abundant eosinophilic cytoplasm and well-defined cell borders.
Immunohistochemical analysis was performed and revealed strong and diffuse reactivity with keratins AE1/AE3, ERG, and FLI1 in both the spindle and the epithelioid neoplastic cells. Markers of muscular differentiation (desmin, myogenin, MyoD1, and smooth-muscle actin) and melanocytic markers (S100-protein, HMB-45, and melan-A) were negative.
The neoplastic cells had a large round vesicular nucleus with stippled and marginated chromatin, indistinct nucleoli, moderate eosinophilic slightly vacuolated cytoplasm, and indistinct cell borders.
Neoplastic cells in MF are CD3+, CD4+, CD45RO+, CD8-.
Neoplastic cells were dyscohesive, having round-oval nuclei with finely granular to vesicular chromatin.
The term 'leukemia' is used when neoplastic cells are seen in blood and/or bone marrow.
A histopathological examination revealed an infiltrative neoplastic epithelial lesion, neoplastic cells having a medium-sized eosinophilic cytoplasm, and mildly pleomorphic round vesicular nuclei.
The tumor was composed of large nests of neoplastic cells with squamous appearance, separated by scanty stroma (Figure 3).
With vessel occlusion by intravascular neoplastic cells, one would expect to find decreased postcontrast enhancement as seen in our case.
The neoplastic cells exhibited an angiocentric growth pattern, as well as angiodestruction with mural fibrinoid necrosis and hemorrhage (Figure 5).
The neoplasm was composed of sheet-like and glandular neoplastic cells embedded in abundant loose fibrovascular stroma.
