| anonymous | Inflammatory pseudotumour (100%) | Advise special stains +/- culture to exclude infective process. | 90 |
| anonymous | Inflammatory pseudotumour (90% probability) | - Infection (5% probability) has to be excluded by performing special stains for microorganisms. - Follicular dendritic cell (FDC)sarcoma (5% probability) has also to be excluded by performing immunostains for FDC markers CD21 and CD35 | 90 |
| anonymous | Inflammatory pseudotumor. 100% | Nil | 100 |
| anonymous | Inflammatory pseudotumor. 100% | Need to exclude an infective cause, particularly mycobacterial infection. Special stains such as Ziehl-Neelsen and Grocott stains should be performed. | 100 |
| anonymous | Left eye limbal mass : INFLAMMATORY PSEUDOTUMOUR. ( 100 % ) | Although in most cases a specific aetiology cannot be identified, some cases are associated with Rosai-Dorfman's disease or inflammatory fibrosclerosis. Special stains for organisms may be performed in some cases to exclude an infectious cause. | 90 |
| anonymous | Kaposi sarcoma 90% Haeangioendothelioma inflammatory pseudotumour | PAS stain for eosinophilic globules of Kaposi. CD34 positive in spindle cells. Any history of aids or immunosuppresion would support Kaposi. | 10 |
| anonymous | Spindle cell lesion Ddx: Inflammatory pseudotumor 50%; FDC tumor 30% Infection 20% | Special staining for organism e.g. PASD for fungus, ZN for AFB Immunostaining for FDC markers | 100 |
| anonymous | Chronic lymphohistiocytic inflammatory lesion. 100%. | Suggest special stains +- molecular studies to look for microorganisms, eg. ZN stain for Mycobacteria; Grocott stain for fungi etc. | 100 |
| anonymous | Inflammatory mass. DDx between inflammatory pseudotumor and other granulomatous infections. 100% | Do infective stains e.g. Ziehl Neelsen, Warthin Starry, Grocott, PAS and Gram stains to rule out organisms. | 100 |
| anonymous | Inflammatory pseudotumour 80% Extranodal SHML 15%% Infection 5% | Special stains to rule out organisms Immunostain S-100 protein to rule out SHML | 90 |
| anonymous | Dendritic cell tumour (80%) Inflammatory pseudotumour if above mentioned studies fail to establish dendritic cell nature (20%) | Immunostains CD21, CD23, CD35, S100, CD1a, CD4, CD68, and if possible, EM for confirmation and classification. | 30 |
| anonymous | Inflammatory pseudotumour with prominent histiocytic reaction 100% | suggest exclusion of fungal & atypical mycobacterial infection by special stains & culture. Also further sampling to exclude presence of a benign fibrohistiocytic tumour. | 100 |
| anonymous | Inflammatory pseudotumor - 100% | Suggest : 1. Ziehl-Neelsen and fungal stains to exclude infection 2. S-100 immunohistochemical stain to exclude Rosai-Dorfman disease (S100 positive for Rosai-Dorfman disease.) | 100 |
| anonymous | Spindle cell lesion with lymphoctes: Follicular dendritic cell sarcoma 90% Inflammatory pseudotumour 5% Other unusual infective process 5% | 1. Immunohistochemical staining: CD21, CD35, etc. for FDC sarcoma. 2. Staining for micro-organisms (correlate with microbiological studies) 3. EM studies | 50 |
| anonymous | Inflammatory pseudotumour 100% | Post-thymic T-cell lymphoma is to be excluded by immunohistochemistry and absence of T-cell receptor re-arrangement. Ziehl_Neelsen stain to rule out mycobacterial spindle cell pseudotumour. | 100 |
| anonymous | Inflammatory pseudotumour. Probability 100%. | - Proceed to a panel of special stains for infective organisms: PASD, Grocott, Ziehl-Neelsen, Wade-Fite. | 100 |
| anonymous | EYE, left eye limbal mass - INFLAMMATORY PSEUDOTUMOR (70%), FOLLICULAR DENDRITIC CELL SARCOMA (10%), MALAKOPLAKIA (10%), MELANOMA (10%) | Suggest special stains including gram, PAS, ZN, giemsa to exclude infective causes, Von Kossa and iron stains for malakoplakia, immunohistochemical staining (CD21, CD35) to exclude follicular dendritic cell sarcoma and S-100 to exclude melanoma. | 100 |
