Given the large number of perikarya and the absence of plexitis, it is possible that the mitosis occupied a perikaryon or sustentacular cell and that the affected ganglion was transitioning from giant ganglion to massive ganglion, though further studies would be required to confirm the identity and significance of the mitotically active cell.
The interstitial tissue of the testis plays a major role in the function of the testis viz., mechanical support to the seminiferous tubules and blood vessels, production of testosterone by interstitial cells (Leydig cells), participation in the sustentacular cell barrier and regulation of the sustentacular cell (Sertoli cell) functions.
Morphologic changes of testis biopsies from diabetic human and testis of diabetic rats were showed that increased tubule wall thickness, germ cell depletion and sustentacular cell (Sertoli cell) vacuolization in both species (Liu et al.
F, Olfactory neuroblastoma showing sustentacular cell staining pattern with S100 immunostain (hematoxylin-eosin, original magnifications X100 [A through C] and X50 [D]; diaminobenzidine with hematoxylin counterstain, original magnifications X50 [E] and X100 [F]).
The results showed that secretory products derived from Sustentacular cell conditioned medium increased cell proliferation and enhanced dopaminergic neuronal differentiation of the 796RMB cell line (Shamekh et al, 2008).
Thus, based on the zell ballen architectural pattern with strong immunoreactivity to CD56 and synaptophysin with sustentacular cell pattern of immunoreactivity to S100 protein confirmed the diagnosis of a paratesticular paraganglioma.
The spindle cells in the periphery of tumour nests (Sustentacular cells) showed strong positivity for S-100 (Figure 8).
D1 and D2 were taken only when D1/D2 [less than or equal to] 0.85, others include epithelial height, testicular weight, sustentacular cells (Sertoli cells) to germ cell ratio (elongated spermatids) (Qin & Lung, 2002).
(7,18) Immunohistochemically, the chief cells are positive for neuroendocrine markers, tyrosine hydroxylase, and GATA3, whilst the surrounding sustentacular cells express S100 and GFAP (glial fibrillary acidic protein).
Immunohistochemistry is useful in making this distinction (1).The chief and sustentacular cells of paragangliomas are immunoreactive to neuroendocrine marker stains, such as chromogranin and synaptophysin, but not to epithelial markers, such as cytokeratin (1, 2, 5).
