🔷Hyperplasia:
The increase in organ or tissue size through increase on cell number .

🔹Stop or limited on removal of the stimulus.

🔹Cells are normal in shape and pattern.

🔷Hydropic change :
Excess water accumulation inside the cells forming vaculces in the cytoplasm.

🔺Gross picture:
Swelling, soft, bloodless, pale organ and the borders are rounded.

🔺Microscopic picture:
The cell are swollen
The cytoplasm pale and shows multiple vaculces
The nucleus is normal

🔷Fatty change:
Accumulation of natural fat in cytoplasm of parenchymal cells.

🔺Gross picture:
Enlarged,
soft organ,
the capsule is tense,
the color is pale yellow
(سبب الـpale color هو الـcompression of capillaries وبالتالي يضعف التغذية الدموية فيكون اللون باهت pale”)
and the borders are rounded.

🔺Microscopic :
The cells are swollen and show multiple tiny fat globules
The nucleus is normal
Capillaries between the cells are compressed.
