RL Non-Odontogenic Lesion Flashcards
What is a nasolabial cyst? Characteristics? Treatment?
Cyst developing from remnants of nasolacrimal duct.
- More common in females
- Elevation of ala of nose
- Swelling of upper lip
Surgical excision.
What are the characteristics of a nasopalatine duct cyst? Radiographic?
- Most Common non-odontogenic cyst
- Swelling of anterior palate with drainage and pain.
- Radiographic: Radiolucent, Well defined, round/oval/heart shape in between incisors.
What is a pseudocysts?
Looks like a cyst, but does not have the classic CT, Epithelium, and Lumen of a real cyst.
What is a traumatic bone cysts/Idiopathic bone cavity/Bone cysts? Treatment?
Benign empty or fluid filled cavity within the bone. No epithelial lining!
-After surgical exploration, heals in 6 months.
What is a stafne bone defect? Characteristics? Radiographic?
Focal concavity of bone on lingual surface of mandible associated with submandibular gland.
-90% male
Radiograph: Radiolucency below mandibular canal, usually with thick corticated borders.
What is a central giant cell granuloma? Characteristics? Radiographic?
Non-odontogenic benign lesion.
- More common in mandible
- Usually in females under 30
- Radiograph: Radiolucent, well defined, Uni/multilocular, can cause expansion or perforation, tends to resorb roots horizontally.
What are the 2 types of Central giant cell granuloma?
- non-aggressive: slowly growing, no root resorption, no perforation of cortical plate. Tends not to recur
- Agressive: pain or paresthesia, root resorption cortical perforation, higher recurrence.
What are the microscopic features of Central giant cell granuloma? Resemble what?
Numerous giant cells.
-Resemble hyperparathyroidism or Cherubism.
What is focal osteoporotic bone marrow defect? Radiographic?
Area of hematopoietic marrow that produce a radiolucency.
-Radiolucent, irregular shape, trabecular pattern still seen.
