Follicular Mucinosis?

Abstract: 27 yo woman with 6 month history of plaques face
HPI: This 27 year-old baker has asymptomatic plaques on the right cheek for six months. She has not been treated as yet.
O/E: Two ill-defined plaques on right cheek. There is a suggestion that follicular openings are dilated.
Clinical Photos:
One can compare the right and left cheeks. Dermoscopic image as well.
Normal left cheek on left, affected right cheek on right.




The image to the right is taken through a dermoscope.
I believe it shows dilated follicular openings.
I am not sure this has been reported.







Diagnosis: Possible Follicular mucinosis

Questions: Do you think this young woman should have a biopsy? Should she be observed? Treated?
