A

1.Fibroma 2.Pyogenic Granuloma 3.Peripheral Ossifying Fibroma 4. Peripheral Giant Cell FIbroma….histodx is Peripheral Giant Cell Granuloma (likely caused by calculus or invasive restoration on a tooth in the area)

Pedunculated

45
Q

_______: a mass that is not supported by a stalk, attached directly by its base; broad surface area of attachment to underlying tissue; the base is the greatest diameter of the lesion

A

Sessile

46
Q

________: growth outward beyond the surface epithelium

A

Exophytic

47
Q

DiffDx&ProvClinDx: A 67 year old female developed a crusted lesion of the left side of her lower lip about a year ago. She stated that she thought her lip was WHITE in that area previously. The lesion had continued to EXPAND. It is now a 1-1.5 cm ULCERATED nodule. On palpation, it is firm and fixed to surrounding tissue.

48
Q

ON EXAMDiffDx(4)&ProvClinDx: A 63 year old ALCOHOLIC. 5 cm mass of the left LATERAL border of his TONGUE. Although the mass is predominantly EXOPHYTIC, it is FIXED to the deeper musculature of the tongue. The surface is ULCERATED and necrotic.

Q

DiffDx&ClinProvDx: A 56 year old white female developed a WHITISH, EXOPHYTIC, papillary growth of the attached GINGIVA around a lower premolar.

51
Q

How is Verrucous Carcinoma different from Squamous Cell Carcinoma?

52
Q

DiffDx(5): A 53 year old African-American male. Slightly RAISED, 1cm mass in the substance of the right lateral border of his TONGUE. The lesion is FIRM and somewhat FIXED to surrounding structures.

A

Pseudoepitheliomatuous hyperplasia :) say that 10x fast. (happens in our granular cell tumors)
