👉 Arctomysis is a medical condition characterized by the presence of numerous tiny, irregularly shaped cells within the skin, which are known as arctomyces. These cells can be found in various areas of the body, including the skin, hair follicles, and sometimes even the lining of the mouth and nose. The exact cause of this condition is not fully understood, but it has been suggested to be related to an overproduction of certain hormones or substances.
