| anonymous | Granulomatous inflammation (100%) | To perform special stains, including ZN, grocott, wade-fite, Warthin-starry stains, to look for organisms. | 95 |
| anonymous | Granulomatous lymphadenitis with florid follicular hyperplasia, toxoplasmosis is most likely, brucellosis and mycobacterium infection must be ruled out. | Serologic studies, special stain and molecular genetic study if necessary. | 90 |
| anonymous | Non-necrotizing granulomatous inflammation, to exclude infection. | Additional clinical history required. Special stains for infective organisms (ZN, Grocott, WS). | 95 |
| anonymous | Reactive change with follicular hyperplasia and granulomatous inflammation. | Perform special studies for organisms (ZN/ Wade-Fite for acid-fast bacilli; Grocott/ PAS-diastase for fungus, immunostaining for cat-scratch disease organism) | 90 |
| anonymous | Granulomatous lymphadenitis. 100% | Special stains eg. ZN and Grocott to look for acid fast bacilli and fungi. Correlate with clinical and culture results for microorganisms. After exclusion of other causes, sarcoidosis is a possibility. | 90 |
| anonymous | Histiocytic/dendritic cell lesion. (100%) | Do CD21 & CD35 to exclude follicular dendritic cell sarcoma. Do S100 protein to exclude Rosai-Dorfman disease. Do Ziehl Neelsen and Wade Fite stains to exclude mycobacterial infection. Do Grocott and PAS stains to exclude fungal infection. Do Warthin Starry stain to exclude syphilis. | 20 |
| anonymous | Granulomatous lymphadenitis 100% | Sarcoidosis is considered after exclusion of mycobacterial or fungal infections. | 90 |
| anonymous | Granulomatous lymphadenitis (100%) | DD'x include 1) infection, 2) other causes of granulomatous inflammation, 3)sarcoid (rare in this locality) and 4) tumours like metastatic carcinoma and Hodgkin's lymphoma (unlikely here). 1) & 2) Perform stains for micro-organisms : Ziehl Neelsen, Gram, PAS, Grocott, Warthin Starry to look for organisms. 4) Perform epithelial marker to exclude minute metastatic carcinoma, examine more blocks to look for minute foci of malignancy. | 95 |
| anonymous | Granulomatous lymphadenopathy | Perform special stains to exclude infectious agents | 90 |
| anonymous | GRANULOMATOUS INFLAMMATION (100%) | Toxoplasmosis needs to be excluded by serology. Ziehl-Neelsen and Grocott stains to exclude mycobacterial and fungal infections. If all negative, sarcoidosis need to be considered. | 90 |
| anonymous | Granulomatous inflammation 100% | cytokeratin to exclude subtle NPC organism stains (ZN, PAS) to exclude TB clinical correlation to exclude sarcoidosis | 90 |
| anonymous | Granulomatous inflammation | Possiblities include infection, reaction to occult tumor and reaction to foreign body. Suggest Ziehl-Neelsen, Wade-Fite and fungal stains to detect specific infectious organisms. | 90 |
| anonymous | Granulomatous inflammation. Do PASD and ZN stain to look for fungus and mycobacterium. Probability: 100% | nil | 90 |
| anonymous | Granulomatous inflammation (100%), favour infective etiology | Infective cause is favoured. Perform special stains for fungus, acid fast bacilli and spirochaetes. Correlate with microbiological studies. | 95 |
| anonymous | Granulomatous inflammation (100%) | Special stains including ZN and PASD for infective organisms. Sarcoidosis is a likely diagnosis if all stains are negative and clincially consistent. | 90 |
