This article collection stuffs about electron microscopy. It is commonly abbreviated EM.
Glycogen
Appearance:
- Cytoplasmic, electron dense, not bound by a membrane.
Seen in:
Tubuloreticular inclusions
Abbreviated TRIs.
Appearance:
- Undulating tubules in the smooth ER, usu. perinuclear.[1]
Seen in:
- Dermatomyositis.
- Inclusion body myositis.
Melanosomes
Appearance:
- Membrane bound, sausage-like shape.
Image(s):
Seen in:
Dense-core granule
- AKA neurosecretory granules
Appearance:[2]
- Round membrane bound, granular core.
- Size: 100-400 nm.
Image(s):
Seen in:
- Neuroendocrine carcinomas.
Birbeck granules
- Seen in Langerhans cell histiocytosis.
Appearance:
- Electron dense, cytoplasmic tennis racket-like body.
Image(s):
- Birbeck granules (photobucket.com).
- Usually... only the handle of the tennis racket is well seen.
