Question 1

Which of the following signs and symptoms are consistent with the diagnosis of Plummer-Vinson syndrome?

Accepted Answer

Plummer-Vinson syndrome is characterized by a triad of symptoms: atrophic mucosa (leading to an esophageal web), dysphagia (difficulty swallowing), and iron-deficiency anemia.

Question 2

Generally, which of the following is the most likely to show microscopic evidence of dysplasia?

Accepted Answer

Idiopathic erythroplakia is more likely to show microscopic evidence of dysplasia compared to the other options listed. Erythroplakia often presents as a red patch on the mucous membranes in the mouth and has a higher risk of malignancy or pre-malignant changes, including dysplasia, than leukoplakia, geographic tongue, or nicotine stomatitis.

Question 3

Biopsy of a mass in the lower lip of a 10-year-old boy showed inflamed granulation tissue. This describes which of the following?

Accepted Answer

The description of inflamed granulation tissue in a biopsy is characteristic of a pyogenic granuloma, which is a type of vascular lesion that often presents as a response to trauma or irritation.

Question 4

Blood dyscrasias (diseases) may manifest themselves orally in which of the following ways?

Accepted Answer

Blood dyscrasias can lead to palatal petechiae due to bleeding disorders or platelet abnormalities, which result in small red or purple spots on the mucous membranes.

Question 5

Examination reveals an asymptomatic 1 * 1 cm red mass between teeth 7 and 8. The patient is pregnant and in good health. Which of the following should be at the top of a differential diagnosis list?

Accepted Answer

Pyogenic granuloma is a common oral lesion characterized by a rapid growth and a red, lobulated mass often seen in the gum tissue. It is particularly prevalent during pregnancy due to hormonal changes, leading to the colloquial name "pregnancy tumor." This makes it the most likely diagnosis for an asymptomatic red mass in the gingiva of a pregnant patient.

Question 6

Kaposi's sarcoma:

Accepted Answer

Kaposi's sarcoma is associated with Human Herpesvirus 8 (HHV8), often presents in the oral cavity, particularly in the palate and gingiva, involves a proliferation of endothelial cells, macrophages, and other inflammatory cells, and is influenced by cytokines and growth factors, making all the provided options correct.

Question 7

It is generally believed that Kaposi's sarcoma is an endothelial cell proliferation that is controlled, in part, by focally produced cytokines and growth factors. The etiologic agent that is believed to mediate this atypical proliferation is:

Accepted Answer

Human herpes virus, type 8 (HHV-8) is the etiologic agent believed to mediate the atypical proliferation seen in Kaposi's sarcoma.

Question 8

A focal proliferative gingival mass composed of granulation tissue in response to local irritation is known as:

Accepted Answer

Pyogenic granuloma is a common, benign, vascular lesion of the skin and mucous membranes that is a reactive inflammatory response to local irritation or trauma, often manifesting as a proliferative mass of granulation tissue.

Question 9

A 68-year-old man presents with a 1 * 2 cm macular red lesion of his hard palate. This is asymptomatic, has been present for an unknown duration, and does not blanch with compression. The best clinical designation for this lesion would be:

Accepted Answer

The lesion is a red macule that does not blanch, suggesting it is not vascular. Erythroplakia is a red patch that cannot be clinically or pathologically diagnosed as any other condition, fitting the description given.

Question 10

HIV-associated Kaposi's sarcoma:

Accepted Answer

Kaposi's sarcoma is associated with Human Herpesvirus 8 (HHV-8), which is one of the herpesviruses.

Question 11

Mental retardation, seizures, and vascular malformation of the face are components of which of the following conditions?

Accepted Answer

These symptoms are indicative of Sturge-Weber syndrome, which is not listed among the provided options.

Question 12

Biopsy of a purple mass in the tongue of a 67-year-old man showed numerous vascular channels lined by benign endothelial cells. The lesion was not encapsulated, and the vascular channels were filled with blood. This is a description of a:

Accepted Answer

This description is characteristic of a vascular malformation, which is a benign lesion consisting of numerous vascular channels lined by benign endothelial cells, often not encapsulated and filled with blood.

Question 13

Trauma or irritation is believed to be an initiating event for which of the following?

Accepted Answer

Pyogenic granuloma is often associated with trauma or irritation as an initiating event, leading to the development of this vascular lesion.

Question 14

Burning mouth or burning tongue syndrome:

Accepted Answer

The answer of Burning mouth or burning tongue syndrome:
...

Question 15

Trauma may be the initiating factor for all the following except:

Accepted Answer

Mucous patches are associated with secondary syphilis, not trauma.

Question 16

Spontaneous involution is a phenomenon that is characteristically associated with which of the following?

Accepted Answer

Congenital hemangioma is known for its characteristic feature of spontaneous involution, often resolving or significantly reducing in size without intervention, unlike the other conditions listed which do not typically resolve on their own.

Question 17

Systemic corticosteroids can be effective in the control of many oral inflammatory/immune mucosal conditions. Which of the following cannot be controlled with its use?

Accepted Answer

Idiopathic erythroplakia is a condition that is not primarily inflammatory or immune-mediated in the same way as the other conditions listed (major aphthae, minor aphthae, and lichen planus). It is a potentially malignant disorder of the oral mucosa, and systemic corticosteroids are not typically used for its control.

Question 18

Which of the following signs and symptoms are consistent with the diagnosis of Plummer-Vinson syndrome?

Accepted Answer

Plummer-Vinson syndrome is characterized by a triad of symptoms: atrophic mucosa (leading to an esophageal web), dysphagia (difficulty swallowing), and iron-deficiency anemia. This combination of symptoms is unique to Plummer-Vinson syndrome.

Question 19

A 23-year-old woman developed an asymptomatic red and partially ulcerated swelling in her buccal gingiva between teeth nos. 24 and 25. She is pregnant and is in good health. This is most likely which of the following?

Accepted Answer

Pyogenic granuloma is a common oral lesion associated with pregnancy due to hormonal changes, often referred to as "pregnancy tumor". It presents as a red, ulcerated swelling on the gingiva, which matches the description given.

Question 20

Ingestion of certain drugs is known to occasionally precipitate which of the following?

Accepted Answer

The answer of Ingestion of certain drugs is known to...
