| anonymous | Schwannoma (100%) | Confirm with immunostain for S100. Also perform CD34 and c-kit to exclude gastrointestinal stromal tumour (GIST). | 100 |

| anonymous | Schwannoma (100%) | IHC: S100 (expected to be positive), C-kit (expected to be negative) | 100 |
| anonymous | Schwannoma | Confirm with immunostaining for S100. Also perform CD117 to exclude gastrointestinal stromal tumor. | 100 |
| anonymous | Schwannoma, 70%. Gastrointestinal stromal tumor, 30%. | Perform S100 and c-kit stains. | 100 |
| anonymous | Neurilemmoma.(100%) | Do S100 protein stain to confirm. | 100 |

| anonymous | SPINDLE CELL TUMOUR 100%, DDX: SCHWANNOMA, LEIOMYOMA, MYCOBACTERIAL SPINDLE CELL TUMOUR. | SUGGEST IMMUNOHISTOCHEMICAL AND SPECIAL STAINS i.e. S100 PROTEIN, ACTIN, ZIEHL-NEELSEN. CYTOLOGICALLY BENIGN BUT SIZE IS RATHER LARGE, NEED TO ASSESS MORE SECTIONS TO DETERMINE NATURE/BEHAVIOUR. | 65 |

| anonymous | Oesophagus submucosal mass - Spindle-cell neoplasm; differential diagnoses including schwannoma and gastrointestinal stromal tumour (please see comment). | Immunohistochemical studies including S100 and CD117 are suggested for confirmation. In case of a typical schwannoma, the tumour cells should show diffuse nuclear positivity for S100 and general negativity for CD117, while the reverse occurs in case of a typical gastrointestinal stromal tumour. Smooth muscle actin can also be performed in order to rule out leiomyoma. | 80 |
| anonymous | Schwannoma | Differential diagnosis: gastrointestinal stromal tumor, to be differentiated by S100 and CD117 immunostaining. | 100 |
| anonymous | Spindle cell tumour, favour benign nerve sheath tumour, confirm with S100, and exclude GIST by CD117 (100% probability) | nil | 100 |
| anonymous | Benign spindle cell tumour, differential diagnoses: 1. GIST (70%) 2. Schwannoma with ancient change (30%) | 1. Perform immunostains for differentiation: GIST positive for c-kit; schwannoma positive for S100. | 60 |
