Evaluation test #11987/2017

QUESTION 1
The distribution of the cells in the acanthomatous ameloblastoma is:
In cords that surround little cellular areas.
The cells are rounded, with scarce basophilic cytoplasm and that expand in sheats.
In nests that contain keratin inside.
The growth-pattern of spindle-shaped cells is characteristic.

QUESTION 2
The differential diagnosis of well localized gingival masses includes:
Gingival hyperplasia, squamous cell carcinoma and acanthomatous ameloblastoma.
Squamous cell carcinoma and fibroma.
Whether mass is ulcerated it is an adenoma.
The gingival masses are exclusively inflammatory processes, not tumor.

QUESTION 3
The origin of the acanthomatous ameloblastoma is:
The enamel layer formed by the odontoblasts.
Gingival epithelium.
Periodontal ligament.
The enamel layer formed by the ameloblasts.

QUESTION 4
The inflammation of the tumoral process is consecutive to:
A gingival hyperplasia secondary to the acanthomatous epulis.
Erosion and / or ulceration of the gingival epithelium.
It is as a consequence of the collision with an oral plasmacytoma.
There is no typical inflammation in this tumor.

QUESTION 5
The prognosis of acanthomatous ameloblastoma is:
Reserved for the infiltrative behaviour of this neoplastic process.
Favorable although it can metastasize to regional lymph node.
Favorable because it has an expansive character.
Poor prognosis due to invasion of lymphatic vessels.
