Study Notes
Fibrinoid Necrosis
- Characterized by pink fibrinous material
- Occurs in immune reactions where antigen-antibody complexes deposit in blood vessel walls
- Can also occur in severe hypertension
- Inflammation/vasculitis (neutrophils) are often present
Endocervical Squamous Metaplasia
- Normal cervix has a smooth, glistening mucosal surface with a small rim of vaginal cuff
- Cervical os is small and round in nulliparous women
- The os has a fish-mouth shape after pregnancies
- Normal cervix has a non-keratinized squamous epithelium on the outside and columnar epithelium on the inside
- Squamous metaplasia occurs when there is irritation
- The histological image shows normal endocervical epithelium and metaplastic squamous epithelium
- If the entire metaplastic cell development results in dysplasia, it becomes Carcinoma in-situ
- Cells are typical and not atypical because it is only metaplasia, not dysplasia
Acute Cholecystitis
- Acute inflammation of the gallbladder
- Gross features include:
- Congestion
- Redness
- Wall thickness
