Multiple schwannomas of the neck, mediastinum, and parapharyngeal space

A rare case of plexiform schwannoma of the lower lip: Treatment and management

“…[ 7 ] Further, secondary changes, such as cystic degeneration, vessels with thick hyaline walls, and haemorrhage [Figure 4a – c ], may occur in Antoni B tissue. [ 2 6 8 9 10 ] These secondary changes were also observed in the present case.…”

“…In Antoni B areas, cystic degeneration, vessels with thick hyaline walls, and haemorrhage were observed. [ 7 8 ] Immunohistochemically, positive S-100 protein and level-7 antigen reactivity confirm the Schwann cell nature of these tumours. [ 1 ]…”

Plexiform Schwannoma of the Lower Lip, Treatment and Management and a Review of Literature

“…Conservative surgical removal is the treatment of choice, with wide excision has achieved normally and no recurrence. [2,5,7,12] These staining results and the associated H&E microscopic findings confirmed the diagnosis of Plexiform Schwannoma in the reported case.…”

Granular cell tumor of the stellate ganglion presenting with Horner’s syndrome

“…Schwannomas and GCT are typically painless and round whereas the non-syndromic (or solitary) neurofibromas are more likely to be painful and fusiform in appearance [40][41][42][43]46,[49][50][51]. In the event that these findings are subtle preoperatively, the spindle shaped histology of schwannomas and neurofibromas on frozen sections is diagnostic [35,49].…”

“…Given that schwannomas and neurofibromas are also benign tumors of Schwann cell origin, they have colors and consistencies similar to GCT (pale yellow/tan and soft) [35][36][37][38][39][40][41][42][43][44][45]. However, the surgeon can usually exclude a GCT based on imaging before entering the operating theater.…”
