| anonymous | Acute suppurative villitis with microabscesses (100%), suggestive of listeria infection. | Gram stain for gram-positive coccobacilli. ZN and Grocott stain to exclude other organisms. Correlate with culture result. | 90 |
| anonymous | Necrotizing villitis with microabscesses formation (100%). Most important differential diagnoses including E Coli and Listerosis. | Special stains for infective organisms (Gram). Correlation with microbiology results. | 90 |
| anonymous | Acute villitis, 100% | Suggestive of Listeria infection. Perform special stain for microorganisms (ZN, grocott, Warthin-Starry) and correlate with microbiologic results. | 100 |
| anonymous | ACUTE NECROTIZING VILLITIS pattern suspicious of LISTERIOSIS. 100% | Listeriosis can be highlighted by Warthin-Starry stain +/- immunostain. Differential includes other infective agent eg. toxoplasmosis(usually granulomatous inflammation). Immunostains, immunofluorescence and PCR can help. Also to correlate with microbiological studies. | 100 |
| anonymous | Acute necrotizing and chronic villitis. (100%) | Do infective stains e.g. Gram, Warthin Starry, Giemsa, Grocott, Ziehl Neelsen, etc to confirm/exclude infection such as syphilis, listeria, fungus, mycobacterium, etc. | 100 |
| anonymous | Acute suppurative villitis and intervillositis 100% | To correlate with microbiologic culture - for evidence of Listeria infection | 90 |
| anonymous | Acute villitis, suggestive of Listeria infection (100%) | To be confirmed by Gram stain (Listeria is a Gram positive bacillus) and culture. | 90 |
| anonymous | Necrotizing villitis 100%, infective aetiology i.e. Listeria, toxoplasmaosis cannot be excluded | suggest correlation with clinical history & microbiological investigation result | 90 |
| anonymous | Necrotizing villitis (Acute/ active chronic villitis, intervillositis with villous necrosis). Viral or bacterial causes should be ruled out. | Histochemical stain and immunohistochemistry test: Gram's Wahrthin Starry, GMS. | 100 |
| anonymous | PLACENTA - NECROTISING VILLITIS. (100%) | Please correlate with culture and serology. Organisms such as Listeria, rubella, toxoplasmosis, malaria should be considered and immunohistochemistry for CMV and herpes could be performed. | 90 |
| anonymous | Acute intervillositis 100% | Suggestive of Listeria monocytogenes infection Intervillous abscess formation with necrosis Perform: - organism stains: gram, PAS - blood culture | 90 |
| anonymous | Acute suppurative villitis | Correlate with microbiological studies to exclude Listeria | 90 |
| anonymous | Acute suppurative villitis | Can be caused by bacteria e.g. Streptococci, Staplylococcus, Hemophilus vaginalis, Listeria monocytogenes and different Gram-negative bacteria. Bacteriological culture should be done. | 90 |
| anonymous | Acute intervillositis with microinfarct and microabscess, need to exclude bacterial infection like Listeria Monocytogenes Perform Gram stain and correlate with culture. Probability: 100% | nil | 90 |
| anonymous | Necrotising villitis with microabscesses; Listeria infection has to be considered 100% | Special stains to look for bacterial, fungal and acid fast organisms. Correlate with clinical and culture findings. If possible, immunohistochemical stain for Listeria antigens | 90 |
| anonymous | Acute intervillositis. | Order tissue Gram's stain for bacteria such as Listeria. | 90 |
