A rare cause of severe ecchymosis: 'Diamond-Gardner syndrome'

Diamond-Gardner Syndrome (DGS) is an autoimmune disease characterized by painful ecchymoses that develop following emotional stress or trauma and is extremely rare. The underlying mechanisms of this disease are still unknown. The majority of cases were reported in women aged 19-72 and only 5% of them were in males. Here, in this case, we present a 45-year-old male patient with bipolar mood disorder and paranoid schizophrenia who was diagnosed with DGS due to severe ecchymoses in both legs and who was successfully treated with escitalopram, cetirizine, vitamin C, and prednisolone as well as psychotherapy.
