What does a skin tag look like under a microscope?
Laboratory preparation of the tissue is required before looking at the skin tag under the microscope. The skin is stained with a stain called hematoxylin and eosin ("H&E"). Under the microscope, there is a colored spherical tissue attached to a small stalk. The purple outer layer (epidermis) overlies a pink core (dermis).
The outer layer of the skin (the epidermis) shows overgrowth of normal skin (hyperplasia), and it encloses an underlying layer of skin (the dermis) in which the normally present collagen fibers appear abnormally loose and swollen. Usually there are no hairs, moles, or other skin structures present in skin tags.
While the majority of skin tags are simply destroyed, sometimes tissue is sent for microscopic exam by a specialist physician known as a pathologist, who will determine the exact diagnosis and determine whether an abnormality such as skin cancer is present. Irregular skin growths that are larger, bleed, or have an unusual presentation may require pathology examination to make sure there are no irregular cells or skin cancers.
Some common skin conditions that can mimic skin tags include seborrheic keratoses, moles, warts, cysts, milia, neurofibromas, and nevus lipomatosus. Rarely, skin cancers like basal cell carcinoma, squamous cell carcinoma, and malignant melanoma may mimic skin tags. Continue Reading
