A

early stage OKCs and ameloblastomas

24

what is the clinical presentation of solitary (traumatic) bone cysts

A
  • normally asymptomatic
  • may have swelling or pain
25
Q

what are the other names for the solitary bone cyst

A
  • unicameral bone cyst
  • solitary bone cyst
  • hemorrhagic bone cyst
  • intravasational bone cyst
  • traumatic bone cyst
  • extravasational bone cyst
26
Q

what is the radiographic appearance of the solitary bone cyst

A
  • unilocular radiolucency with interradicular scalloped superior margins
  • usually greater than 10mm and associated with more than 1 root apex
  • well demarcated but does not have corticated border
  • aggressive lesions can be expansive but most cases arent
27
Q

what is the age, site and gender predilection for solitary bone cyst

A
  • age: second decade, usually less than 25 years but also seen in menopausal age women and same age in men
  • site: body and ramus of mandible
  • gender: no predilection
28
Q

what is the management of solitary bone cysts and is there recurrence

A
  • initiate bleeding
  • recurrence is rare
29
Q

what is the clinical presentation of the posterior lingual mandibular salivary gland depression

A
  • developmental lesion
  • asymptomatic
  • usually found in routine radiographic examinations
  • considered pathognomonic
30
Q

what is another name for the posterior lingual mandibular salivary gland depression

A

Stafne cyst

31
Q

what is the radiographic presentation of PLMSGD

A

-well circumscribed posterior radiolucency in molar region between mandibular canal and inferior border
- can be found in antegonial notch
- may or may not be corticated

32
Q

does the PLMSGD grow

A

yes

33
Q

what is the age, site and gender predilection of the PLMSGD

A
  • age: adults; prominent over 50 years
  • site: between the mandibular canal and inferior border
  • gender: almost exclusively in men
34
Q

what is the management for PLMSGD

A
  • positive diagnosis based on clinical and radiologic history negates the need for biopsy and histologic examination
35
Q

what is the clinical presentation of focal osteoporotic bone marrow defect of the jaws

A

asymptomatic

36
Q

what is the radiographic presentation of the focal osteoporotic bon marrow defect of the jaws

A
  • unilocular, faint radiolucency
  • not ragged but difficult to discern as a separate entity
  • well demarcated, can be trabeculations, no expansion
37
Q

what is the age, site and gender predilection for focal osteoporotic bone marrow defect of the jaws

A
  • age: all
  • site: mandible
  • gender: slightly higher in females but no predominant gender
38
Q

what is the management for focal osteoporotic bone marrow defect of the jaws

A

no treatment

39
Q

what is the pathophysiology of the residual/recurrent cyst

A
  • results from incomplete removal or residual viable epithelial cystic lining following treatment of a cyst
  • previous history of periapical disease
40
Q

what is the clinical presentation of the residual cyst

A
  • asymptomatic, normally found on radiographic examinations of edentulous areas
  • tooth or root may or may not be present
41
Q

what is the radiographic presentation of the residual cyst

A
  • well defined radiolucency with smooth round corticated borderd
  • usually 5mm or less in diameter
  • may not be any root present if tooth was previously extracted
42
Q

what is the age, site and gender predilection for the residual cyst

A
  • age: middle age or older
  • site: more common in maxilla
  • gender: more common in males
43
Q

what is the management of the residual/recurrent cyst

A
  • same as PA cyst
  • requires removal of the cyst lining
  • enucleation if a large cyst
44
Q

what is the pathophysiology of the fibrous healing defect

A
  • develops after inflammation that affects the integrity of the periosteum
  • once disease is eradicated the bone heals without a mineralized bony matrix
  • due to the loss of the periosteum only fibrous connective tissue fills the site of the previous disease
45
Q

what is another name for the fibrous healing defect

A

apical scar

46
Q

what is the clinical presentation of the fibrous healing defect

A
  • asymptomatic
  • noted in areas with a history of disease or trauma
47
Q

what is the radiographic presentation of the fibrous healing defect

A
  • well circumscribed radiolucent lesion at site of previous surgery
  • punched out or see through appearance
  • may resemble residual cysts in edentulous areas but lack of cortication
48
Q

fibrous healing defects are seen where:

A

there was trauma such as endo or mandibular fx

49
Q

what is the management for the fibrous healing defect

A
  • no treatment indicated
  • a previous history of disease is critical in establishing the diagnosis
50
Q

what is the clinical presentation of the neuroma, neurofibroma

A
  • expansion, pain or paresthesia
  • symptoms include complaints of burning, tingling and aching sensations
51
Q

what is the radiographic presentation of neuroma, neurofibroma

A
  • well circumscribed radiolucency of various shapes
  • in the mandible it usually forms in the mandibular canal
  • benign
52
Q

what is the management of the neuroma, neurofibroma

A
  • excision
  • recurrence is rare
53
Q

what are the other odontogenic cyst like radiolucencies

A
  • ameloblastoma
  • central giant cell granuloma
  • cementoossifying fibroma
54
Q

what are the other non-odontogenic cyst like radiolucencies

A

-chronic localized langerhans cell disease
- myeloma
