Abstract Morbihan's disease is a rare condition characterized by chronic facial edema. While its exact cause is unknown, it is thought to involve local cutaneous vascularization and lymphatic drainage imbalance. Traditional treatment options are often ineffective, and no established efficient treatment exists. We present a case study of a 17‐year‐old male with Morbihan's syndrome who showed resistance to traditional treatments but responded well to a combination of cromolyn sodium nasal spray and oral montelukast after histopathology revealed hyperplasia of plasma cells and mast cells. This combination has not been used before for Morbihan's syndrome. Our review of the literature also provides insight for clinicians seeking to manage this condition.
