1. Lab pathology slides

2. • Fatty degenerative liver
There are severe fatty
changes and many
hepatocytes are atrophied

3. • Cirrhosis liver
Hepatocytes are
normal , septa is
fibrosis and contains
inflammatory cells

4. • Primary carcinoma liver
• Aggregation of malignant cells (high nuclear –
cytoplasm ratio , hyperchromatic , irregular nuclear
membrane, pleomorphism ) , hemorrhage and
dilated blood vessels

5. • Ulcerative colitis
rectum
• In mucosa there are
hemorrhage ,
inflammatory cells
(mostly lymphocytes)
and dilated blood
vessels
• Submucosa and
muscularis contain
inflammatory cells
(plasma cells and
lymphocytes)

6. • Adenocarcinoma of pancreas
• Malignant cells in the wall of gland and
there are neutrophilis and lymphocytes in
the lumen of the gland

7. • Acute peptic ulcer
There are ulceration
and neutrophilis
Note : to differentiate it
from ulcerative colitis ,
the acute peptic ulcer
do not contain dilated
blood vessels and the
glands are regular

8. • Chronic peptic ulcer
Infiltrated gastric mucosa by inflammatory cells
associated with surface ulceration, the ulcer is filled
by necrotic cells and debris and inflammatory cells
accompanied by granulation tissue

9. • Mixed tumor of
salivary gland
Proliferation of
epithelial and
myoepithelial cells
associated with
mesenchymal tissue

10. • Acute suppurative appendicitis
Heavy infiltration of acute inflammatory
cells (neutrophils that infiltrate mucosa ,
submucosa, muscularis)
There are also fat cells

11. • Ulcerative colitis
rectum
mucosa is ulcerated
and contains
inflammatory cells
and dilated blood
vessels
Submucosa and
muscularis contain
inflammatory cells
(lymphocytes and
plasma cells)

12. • Gastric carcenoms
Proliferation of malignant gland (high
nuclear – cytoplasm ratio , hyperchromatic ,
irregular nuclear membrane, pleomorphism)
malignant gland invade the underlying
submucosa and muscularis propria)

13. • Colon adenocarcinoma
Proliferation of
malignant gland (high
nuclear – cytoplasm ratio ,
hyperchromatic , irregular
nuclear membrane,
pleomorphism) that
infiltrate submucosa
