لاحظ الفرق بين :
Fat accumulation, Far Necrosis

Fat necrosis with Ca Deposition

Fat Accumulation

Fat necrosis

هنا شوفوا كيف يكون ال Calcification

اليمين مع ال Fat Necrosis

اليسار مع ال Caseous Necrosis of lymph node

فرقنا اول بين ال Apoptosis/ Necrosis


❗️Diagnosis:
Apoptosis of cell

❗️Characteristic features:-

✨Lastly:

موضوع ال Accumulation

تكلمنا عن ال Hydropic/ Fat accumulation وال Calcification انو يترسب ال Ca ..
و ال Lipid and Protein accumulation

طيب ؟؟

باقي عندي مواد ممكن تتراكم في حالات معينة ولها صور مميزة
