Several amounts of ghost cells
were found within the epithelial component and also in the capsule (Figure 3(c)).
odontogenic carcinoma may arise from other benign ghost cell
tumors; dentinogenic ghost cell
tumor and calcifying odontogenic cysts.
In particular, there should be future research directed to pathogenesis of ghost cell
odontogenic carcinoma and malignant granular cell odontogenic tumour.
No ghost cells
are used and the entire 3D domain is treated as a single global array by the parallel program.

Wet keratin is also known as "ghost cells
" based on the preservation of cell outline, albeit with loss of nuclear hematoxylin staining.
A giant cell tissue reaction is commonly seen surrounding ghost cells
(C) (hematoxylin-eosin, original magnification X200 [A through C]).
(5) Cytologically, it can be misdiagnosed as a malignancy when basaloid cells predominate the aspirate, more so in the absence of ghost cells
. (4) Recurrences and malignant transformations are rare.
Note that the computation of both x- and y-derivatives requires quantities inside the solid region, in other words, in the ghost cells
. For MS2, these quantities are estimated by the simplified version (avoiding recursive interpolation and extrapolation) of the ghost-cell method .
They progressively evolve into ghost cells
in the center of the lesion.
Histopathologic examination provides the correct diagnosis and shows solid nests of basaloid cells with the formation of ghost cells
with foreign-body giant-cell reaction, calcification, and ossification in some cases.
(1,2,5) Histopathology generally demonstrates irregular islands of epithelial cells with biphasic architecture of central ghost cells
and varying amounts of basaloid cells in the periphery.
