Abstract
Primary hyperfibrinolysis States are rare entities associated with different clinical scenarios and can be sometimes their first presentation. PHS outcome relies on the underlying cause. We introduce the case of a man presenting with a complex clotting abnormality malignancy related. Not having an accurate diagnosis hindered us to give an easy solution and compromised the prognosis overall. Misdiagnosing a severe entity often leads to fatal outcomes. We want to highlight the rarity of our case, the challenging differential diagnosis and the importance of being aware of PHS. Because our patient appeared to have an extended carcinoma, definitive treatment was not an option on our case.When an uncommon and challenging disease is presented, having all the clues is mandatory to succeed.
