  1. Oral Pathology Final Review

  2. Gastric regurgitation causes which of the following? A. Erosion • B. Abrasion • C. Attrition • D Hypercementosis

  3. Erosion

  4. A patient states that for almost a year now, she has had a rubbery, firm, painless nodule within the substance of the parotid gland. The condition is MOST likely a: A. Mucocele • B. Lymph node • C. Benign Mixed Tumor • D. Squamous Cell Carcinoma • E. Sialolith with encapsulation

  5. BenignMixed Tumor • Pleomorphic Adenoma (Benign Mixed Tumor) The palate is the most common intraoral location, but these tumors may be found in any area where salivary gland tissue is present • Most common salivary gland neoplasm – accounts for about 90% of all benign salivary gland tumors.

  6. Primary herpetic gingivostomatitis is MOST likely to occur in which of the following age groups? • A. 1 – 5 years • B. 6 – 10 years • C. 11 – 15 years

  7. Primary Herpetic Gingivostomatitis • Painful • Erythematous • Edematous • Most common in children 6mos to 6 yrs. • Perioral skin, vermillion border of lips & oral mucosa

  8. Which of the following lesions has the greatest malignant potential? A Leukoedema • B. Lichen Planus • C. Actinic Cheilitis • D. White Sponge Nevus

  9. Actinic (Solar) Cheilitis

  10. A patient has painful lesions on her buccal mucosa. A biopsy reveals acantholysis and a suprabasilar vesicle. Which of the following represents the MOST likely diagnosis? A Pemphigus • B. Psoriasis • C. Erythema Multiforme • D. Bullous Lichen Planus • E. Systemic Lupus Erythematosus

  11. Pemphigus Acantholysis= epithelial cell separation 50% of cases the first signs appear in the oral cavity. Gentile finger pressure with movement on clinically normal mucosa can produce a cleavage in the epithilelum and result in the formation of a bulla. This is called Nikolsky sign.

  12. The MOST common location for a mucous retention swelling or mucocele is the: A. Tongue • B. Gingiva • C. Upper lip • D. Lower lip • E. Buccal mucosa

  13. Lower lip • Forms when minor salivary gland duct is disrupted and mucous salivary gland secretion enters the adjacent connective tissue • Most common on lower lip • Size may decrease over time • Minor salivary glands

  14. A patient presents with a bilateral, grayish-white lesion of the buccal mucosa. This lesion disappears when the mucosa is stretched. Which of the following is the MOST likely condition? A. Leukoedema • B. Leukoplakia • C. Lichen Planus • D. White Sponge Nevus • E. Pachyonychia congenital

  15. Leukoedema • Accumulation of fluid within the epithelial cells of the buccal mucosa.asymptomatic bilateral, diffuse, grayish-white, milky, opalescet appearance of the mucosa will disappear when applying the clinical "stretch test"

  16. Which of the following lesions is the MOST likely to become malignant? • A. Papilloma • B. Leiomyoma • C. Lymphangioma • D. Junctional Nevus • E. Granular Cell Tumor

  17. Junctional Nevus

  18. Ameloblastoma of the mandible is similar radiographically to which of the following conditions? A. Osteosarcoma • B. Pindborg Tumor • C. Ameloblastic Fibro-odontoma • D. Central Giant Cell Granuloma

  19. Remember….sarcoma is a term reserved for a malignant neoplasm of embryonic connective tissue origin.

  20. A 22-year old female patient has a diffuse erythema of the gingiva with scattered, isolated ulcers on the tongue and in the Oropharynx. The marginal gingiva is edematous and inflamed. Her condition is of three days’ duration, is painful; and she has an elevated temperature and malaise. The MOST likely diagnosis is: A. Apththous stomatitis • B. Erosive Lichen Planus • C. Benign Mucous Membrane Pemphigoid • D. Acute Herpetic Gingivostomatitis

  21. Apthous Stomatitis

  22. Apthous Stomatitis • Young female • Located on soft palate, tonsillar fauces, labial mucosa, buccal mucosa, and tongue.

  23. Metastatic carcinoma to the jaws is LEAST likely to arise from the: • Brain • Breast • Kidney • Prostate • Lung

  24. Brain • Least likely….not usually carcinoma

  25. Radiographs of a patients’ teeth reveal that the crowns are bulbous; the pulps obliterated; and the roots shortened. These findings are associated with which of the following? • Porphyria • Pierre Robin Syndrome • Amelogenesis Imperfecta • Dentinogenesis Imperfecta • Erythroblastosis fetalis

  26. Dentinogenesis Imperfecta

  27. The routine examination of a healthy 20-year old man discloses a round, brown lesion, 3mm in diameter, on his lower lip. The lesion is solitary, asymptomatic, and flat. Its duration is unknown. Which of the following is the MOST likely diagnosis? • Blue nevus • Focal melanosis • Compound nevus • Malignant melanoma • Peutz-Jegher’s Syndrome

  28. Focal melanosis • Flat circumscribed pigmentation of the lip ofr mouth • Usually single, • Less than 1cm in diameter • Common in light-skinned persons between 25 & 45 years

  29. Papillary hyperplasia is MOST frequently found in which of the following sites? • Hard palate • Soft palate • Anterior gingival tissue • Posterior gingival tissue

  30. Inflammatory Papillary Hyperplasia of the Palate • A reactive tissue growth that usually develops beneath a denture

  31. Which of the following reactive lesions of the gingival tissue reveals bone formation microscopically? • Peripheral ossifying fibroma • Traumatic neuroma • Pyogenic granuloma • Irritation fibroma • Osteoma

  32. Osteoma

  33. In which of the following locations do premalignant lesions of squamous epithelium MOST often appear (in the U.S. population)? • Palate • Gingiva tissue • Buccal mucosa • Lateral border and ventral surface of the tongue • Dorsal surface of the tongue

  34. Lateral border and ventral surface of the tongue

  35. Which of the following clinical lesions MOST often reveals histologic evidence of severe dysplasia or carcinoma in situ? • Leukoedema • Leukoplakia • Lichen Planus • Erythroplakia • White Sponge Nevus

  36. Erythroplakia

  37. A patient, who has been taking penicillin for three weeks, presents with slightly painful white lesions on the tongue, palate, and cheeks. A dentist wipes the lesions with gauze and notes that they have red surfaces. The most likely diagnosis is: • Lichen Planus • Candidiasis • Erythema multiforme • Primary herpetic gingivostomatitis

  38. Candidiasis

  39. A patient has two or more of here teeth joined only by cementum. This phenomenon is known as: • Fusion • Hypercementosis • Gemination • Dilaceration • Concrescence

  40. Concrescence

  41. The virus that causes acute herpetic gingivostomatitis is closely related to the virus that causes: • Mumps • Measles • Chickenpox • Cat-scratch disease

  42. Chickenpox

  43. Each of the following diseases has been associated with the Epstein-Barr virus EXCEPT one. Which one is this exception? • Burkitt’s lymphoma • Oral hairy leukoplakia • Infectious mononucleosis • Adenoid cystic carcinoma

  44. Adenoid cystic carcinoma

  45. Epstein-Barr Virus Infection • Infectious Mononucleosis • Most common in late adolescents and young adults in upper socioeconomic classes (transmitted my close contact-ex=kissing) • Hairy Leukoplakia • Most common in HIV infected people • Nasopharyngeal carcinoma-rare neoplasm • Burkitt lymphoma-rare neoplasm

  46. Squamous cell carcinoma appears in a variety of locations. In which of the following locations is its prognosis the LEAST favorable? • Lower lip • Floor of the mouth • Hard palate • Buccal mucosa • oropharynx

  47. oropharynx

  48. Squamous cell carcinoma of the tongue MOST commonly metastasizes to which of the following? • Lungs • Liver • Bones • Cervical nodes

  49. Cervical nodes
