rejection morphology

A

LLL=3 patterns
PEM

3PEM

Tubularintersitial pattern 1 هنا يوجد ليفوسايت وبلازما سيلس جوا الرينال تبيولزس وحوله
Vascular pattern 2 هنا التهاب في الانديثيلوم احصل خلايا الانديثيليوم منتفخه وبينه او تحته خلايا لفيموسايت
Necrosis pattern 3

P has parenchymal injury usually heamorge
E edema
M mononuclear infiltration

Q

Morphology of chronic rejection

A

Vascular changes (3 things )

  • intima thickness increases
  • sm thickness increases
  • vascular acclusions

Interstitial inflammation/ fibrosis

Tubular atrophy

هنا الكيديني تيبيولز صار له أتروفي لأن الأوعية الدموية اللي تغذيه تم انسداده على فتره طويله والأوعية الدموية أصلا تحتاج وقت على بال مايظهر به أي تغير عشان كذا التغير بالأوعية الدموية ينشاف مع ال chronic rejection
