What Is a Subcutaneous Cyst?

It occurs at any age, and it is more common in the head, arms, and back in youth. It is a soft or multiple soft or solid spheres with diameters ranging from 1 to 3 cm. Powdery tumors are buried in the skin or subcutaneous tissue and adhere to the skin, and the substrate can be moved. There are small openings on the skin surface. When the cyst is pushed, it adheres tightly to the skin, and there are slight depressions and small pits, which are the openings of the catheter where the glands directly reach the surface of the skin. Some openings are plugged with a small black acne-like plug to squeeze out white wax-like substances. Onset of symptoms for many years, easy to secondary infection, purulent ulceration, and some strange smell. There are reports of cancerous changes in the literature, most of which have turned into basal cell carcinomas and a few into squamous cell carcinomas, with a canceration rate of about 2.2% to 4%.
