Pathology buzz words Flashcards
Antoni A and Antoni B cells
Spindle cell tumor most likely neurolemoma (schwanoma). Spindle A are closely packed, Spindle B loosely
Blessig-Iwanoff cysts
found in peripheral outer plexiform cystic degeneration
Busacca nodule
granulomatous mass near base of iris, found in Sarcoid
Cowdry Type inclusions
eosinophilic intranuclear inclusions of Herpes simplex
Dalen-Fuch’s nodules
transformed RPE cells and histiocytes
Dutcher body
intranuclear Ig in plasma cells, seen also in lymphoproliferative disease
Fite stain
Acid-Fast Bacillus stain
Gamori Methenamine silver stain
Fungal stain
Gitter cells
lipid laden macrophages
Gunn’s dots
found in juvenile retinoschisis
Halberstaedter-Prowazek inclusions
chlamydial inclusions (basophilic intracytoplasmic inclusions)
Henderson-Paterson Corpuscles
Eosinophilic inclusion bodies seen in molluscum contagiousum
Horner-trantas dots
degenerated eosinophils seen as nodules at the limbus in vernal keratoconjunctivitis
Koeppe nodule
granulomatous mass near “Korner” of pupil, found in Sarcoid
Langhan’s cell
Histiocyte conglomeration, found in TB and sarcoid. No lipid rim, horseshoe shaped.
Merkel cell tumor
very malignant tumor arising from mechanoreceptors of touch, rare and deadly!
Morgangnian globules
cortical degeneration of lens
Psamomma body
round calcifications seen in meningioma
Rosenthal Fiber
“worm-like” eosinophil glial materal that is non-specific but found in pilocytic astrocytoma AKA optic nerve glioma)
Russell body
constipated plasma cell, cytoplasmic inclusion Ig
Schaumann body
Giant cell inclusion body found in sarcoid, laminated appearance
Touton giant cell
histiocyte conglomeration in round formation. Has lipid rim (stains with oil red O), noted in JXG and Erdheim-Chester disease (contrast with Langhan’s cell)
Waite-Beetham lines
Faint but deep stromal wrinkles seen with corneal edema
Warthin-Starry stain
Silver stain for Bartonella Henselae in Cat-Scratch disease
