Pigmented, raised, warty lesions over the face and trunk should be assessed by an experienced practitioner who can distinguish:

a. sebaceous hyperplasia from eczema.
b. furuncles from folliculitis.
c. cutaneous tags from lentigines.
d. seborrheic keratoses from actinic keratoses.

The Practitoner should be ab;e to distinguish Seborrheic keratoses from Actinic keratoses - D

Explanation: This is because even though they look similar,

Actinic keratosis starts with formation of rough, unclear spots that are less than a square inch in area. which develop into reddish  scaly plaques which are also flat or slightly raised. Seborrheic keratosis on the other hand  is significantly different because it involves blockage of pores which only prevents hair growth in the affected skin which Actinic keratosis does not.
