  5. 5. THE CASE MALE – 32 Swelling on the left side of the lower jaw since 8 months that gradually grew in size. The left lip and the chin area subsequently felt numb. There was no associated pain. Family History: Not relevant Past Medical History: He was treated elsewhere one month back.
  6. 6. CLINICAL PRESENTATION ON EXTRAORAL EXAMINATION: A Brawny hard swelling of the left body of the mandible was noted. The swelling was non-fluctuant. ON INTRAORAL EXAMINATION: A Brawny hard swelling was felt over the left buccal cortical plate with respect to teeth region #32, #33, #34, #35, #36 and #37. The left lower buccal vestibule was obliterated.
  7. 7. RADIOGRAPHIC INTERPRETATION Well defined radiolucent osteolytic lesion present at the left body of the mandible with some fine wispy trabeculae. There are multiple root resorption of the teeth on the left lower jaw. The lesion appears cystic and expansile with medullary hollowing out, thinning of the cortical plates and approaching the lower border of the mandible.

  14. 14. • It is uncommon in a younger age range, which is most susceptible to giant cell granuloma. • Seen in posterior mandible in contrast to giant cell granuloma which occurs anterior to the first molar. • Ameloblastoma demonstrates internal, hard curved arch like septa whereas giant cell granuloma has lighter wispy septa. • Ameloblastoma is usually multiloculated AMELOBLASTOMA
  15. 15. Ameloblastoma is a true neoplasm of enamel organ type. Unicentric, nonfunctional, intermittent in growth, It is the second most common odontogenic neoplasm. Mandible > Maxilla (molar-ramus area region.) AMELOBLASTOMA

  24. 24. • Parathyroid hormone (PTH) is released in response to decreased serum Ca  PTH increase Ca by: causing an efflux of Ca from the bony skeleton increased reabsorption by the kidneys. PTH also leads to increased release of vitamin D from the kidneys, which in turn causes increased Ca absorption from GIT. • Conversely, PTH leads to decreased P levels due to increased excretion by the kidneys. BROWN TUMOR OF HYPERPARATHYROIDISM
  25. 25. • Primary HPT  one or more parathyroid glands secrete an excessive amount of PTH, eg. parathyroid adenoma; • Secondary HPT  increased secretion of PTH is a response to lowered ionized calcium, typically as a result of renal disease. • In Tertiary HPT  secretion of PTH occurs as a result of long-standing chronic renal disease eventually leading to overactive parathyroid glands that become independent of the underlying disease. Hence, tertiary HPT is not corrected when patients receive a renal transplant that corrects the underlying renal etiology BROWN TUMOR OF HYPERPARATHYROIDISM
  26. 26. • Uncontrolled HPT  BTHPT. • Presents late in untreated disease • Extensive bone resorption, which is replaced by fibrovascular tissue and giant cells with abundant deposits hemorrhage and hemosiderin. BROWN TUMOR OF HYPERPARATHYROIDISM
  27. 27. • Histology – Similar to central reparative giant cell granulomas. histologically  abnormal calcium homeostasis in HPT. BROWN TUMOR OF HYPERPARATHYROIDISM

  31. 31. Calcium is maintained within a fairly narrow range from 8.5 to 10.5 mg/dl (4.3 to 5.3 mEq/L or 2.2 to 2.7 mmol/L). The Normal Serum calcium levels ? A) 8.5 to 10.5 mg/dl B) 4.3 to 5.3 mg/dl C) 2.2 to 2.7 mg/dl D) 15 to 20 mg/dl
  32. 32. • ABC is a giant cell lesion within a fibroconnective tissue stroma with blood caverns or sinusoids and no epithelial lining. • A reactive lesion of bone rather than a cyst or true neoplasm, • it occurs in posterior segment of mandible, posterior to molar region. • Aspiration produces blood ANEURYSMAL BONEC CYST
  33. 33. • The radiographic features are not pathognomonic and are sometimes confusing. • Can mimic a Neoplasm • An associated periosteal reaction with reactive new bone forming a peripheral sclerotic border (difficult to differentiate from a subperiosteal hematoma) ANEURYSMAL BONEC CYST
