What causes exophytic cysts?

Exophytic cysts are typically caused by the abnormal growth of tissue, often resulting from a blockage in the ducts or glands, leading to fluid accumulation. They can arise from various factors, including infections, inflammation, or genetic predispositions. Additionally, certain conditions like epidermoid cysts or sebaceous cysts can contribute to their formation. In some cases, they may also be linked to underlying tumors or lesions.
