Histopathologic picture of proliferative periostitis

A

1.Trabeculae of woven bone: arranged in parallel rows or retiform (interconnecting meshwork), often perpendicular to the surface.
2.Intertrabecular loose, vascular, uninflammed fibrous connective tissue.

Q

Primary chronic ostemyelitis (PCO) and diffuse sclerosing osteomyelitis (DSO): what is the difference in the clinical presentation?

A

PCO: pain, swelling
DSO: no pain and swelling

17
Q

PCO: clinical picture

A

Pain
Swelling (bone expansion) Facial deformity
Trismus
Lymphadenopathy
Loss of sensation

The nature of the disease is cylic: periodic episodes of flares and remissions

18
Q

A

PCO:

NO fever
NO pus discharge
NO fistula formation
NO sequestration of bone

CSO: the above signs are present.

19
Q

A

PCO:
radiographic features can include the following:
1.RL lesion (osteolysis)
2.Mixed RL-RO lesion
3.RO lesion (osteosclerosis)
4.Periosteal thickening
5.External bone resorption

DSO:
Diffuse radiopacity

20

Corticosteroids
Pamidronate
Denosumab
Calcitonin
Tumor necrosis factor-a antagonists
Hyperbaric oxygen
Decortication

21
Q
