Slide Review: Monsel's Solution

Monsel's solution, also known as ferric subsulfate solution, is a styptic agent used to stop bleeding after superficial skin biopsies.  It works by contracting tissue to seal injured blood vessels. Here, we see residual Monsel from a biopsy done several days before Mohs surgery.

Slide Review: Milial Cyst

A milial cyst is a small, keratin filled cyst, often found on the face. This lesion is quite common in women who apply moisturizers, and can also be a complication of facial cosmetic dermatology such as dermabrasion, chemical peels, and laser resurfacing.

The hardened keratin sounds like a grain of sand embedded in the tissue, making a scraping sound at each pass of the blade. 

In these sections, you can see the stratified layers of keratin lining the cyst.
