Rosai-Dorfman syndrome

Rosai-Dorfman syndrome is a rare disorder where certain immune cells called histiocytes grow excessively, leading to painless swelling of lymph nodes, especially in the neck. It can also affect other tissues and organs, causing symptoms like fever, skin issues, or organ enlargement. The exact cause is unknown, but it’s believed to involve immune system dysfunction. While often self-limiting and resolving on its own, some cases may require treatment like surgery or medications to reduce symptoms. Overall, it’s a benign condition, but proper diagnosis and management are important to monitor and address any complications.
