White areas at autopsy found in the abdomen
Saponification
= classic feature of acute pancreatitis
Bilateral pleural effusions and heavy lungs at autopsy
Acute pancreatitis
ARDS pathological features
Hyaline membrane formation
Osteoclast
Bone destroyer
Bone found at the epiphysis
Trabecular
Outer shell/shaft of long bone

Lines around the osteon
Cement lines
ECM
75% water, 25% organic material
Lucent, painless lesion on x-ray
Simple bone cyst
Tumour often occurring around the knee and distal radius with a soap bubble appearance
Giant cell tumour
A single lucent lesion, often an incidental finding, found most commonly within metaphyseal regions
Simple bone cyst
A tumour extensively involving the proximal femur with cortical thinning and a Sheperd’s crook deformity
Fibrous dysplasia
Osteochondroma
Produces a cony outgrowth in the external surface with a cartilaginous cap
