Expired cream: All medicines have expiration dates. The primary purpose for these expiration dates is to ensure freshness, quality and consistent efficacy with the drug. If a drug is out of date, it is best not to use it.

What does benign follicular cells in mixed micro macrofollicular pattern, focal hurthle cell changes histiocytes mean? 3cm nodule on thyroid fast grow

Review with doctor: Follicles are hollow balls with cells on the outside and a protein-containing liquid called colloid on the inside. Microfollicles are small balls made up almost entirely of cells with very little colloid in the center. Macrofollicles are large balls with much more colloid in the centers. Normal thyroid tissue is mostly macrofollicles, but may include some microfollicles as well.

The relative mix is important. More microfollicles would suggest possible tumor (benign adenoma, or possibly cancer)

Micro-clotting: So why do you think you have micro-clots? A clot would cause cessation of blood flow and necrosis of tissue. What you might be seeing is some skin discoloration?

How do you reduce skin peeling while using differin (adapalene) gel?

2 doctor answers6 doctors weighed in
Dr. Michael Fisher
Dermatology 32 years experience
Peeling skin: The makers of differin (adapalene) actually advise users to use moisturizer. Specifically, they mention a moisturizer that is non-comedogenic (won’t clog pores) while your skin is still a little damp. All moisturizers should be put on while your skin is a little damp, by the way. The fda also advises users to use moisturizer if you have the side effect of dry skin, or use the product less frequently.
