4. Basal cell carcinomas (BCC) metastasize quickly and is a fast growing lesion. Patients will often report the growth came out of nowhere and they just noticed it

True

False

Metastasis is unlikely if it does it will go to the regional lymph node. Therefore you need to palpate preauricular and sudmandiublar nodes for swelling and tenderness.
Patients will most likely report that it has been there for a long time, it doesnt' go away and does not heal

It spreads by direct metastasis

5. Absence of superior lid sulcus in Caucasian people will lead you to believe the person could have a congenital ptosis, especially if the person is young.

True

False

The absence of a superior lid sulcus in Caucasian people can indicate a congenital ptosis, particularly in younger individuals. This suggests that the person may have been born with a drooping upper eyelid, which could be a result of a developmental issue. Therefore, it is true that the absence of a superior lid sulcus in Caucasian people could lead one to suspect a congenital ptosis.

9.

You have a 57yo Caucasian male who comes into to your office after an OMD gave them a referral for VT. during slit lamp evaluation who notice there appears to be an adhesion b/t the upper and lower eyelids on the temporal aspect of their eye. You have the patient look to the right and to the left and tug on the eye a little bit, You can envision where the eyelid probably once was. Since this is only present on one eye it gives the patient the appearance of a strabismus. You decide to place the patient on immunosuppressive medication, b/c this acquired anomaly is normally due to autoimmune condition, in this case you chose cyclosporine.

Therefore, a verruca is a type of papilloma that is specifically caused by HPV.
