👉 Metasolenostomy is a condition characterized by an overgrowth of cells in the skin or mucous membranes that resemble a metasomatic body, often seen in elderly individuals due to various conditions like rheumatoid arthritis, psoriatic arthritis, and other autoimmune diseases. Metasolenostomy typically occurs as a result of inflammation, immune response, or related conditions that lead to an increase in cell numbers in the skin or mucous membranes.
