DIC, unlikely: PT/PTT normal; wouldn't just see gum bleeding
hypersplenism: would cause anemia
iron deficiency: anemia
vitamin C deficiency: wouldn't cause thrombocytopenia
von Willebrand disease: mixed platelet/coagulation disorder โ would cause deep joint bleeding instead of mucosal membrane bleeding. Inherited (Autosomal Dominant), would see symptoms before. PTT can be normal/high.
betoBleeding symptoms in von Willebrand disease tend to occur in mucous membranes. deep joint bleeding is rare+5
castlblackNew onset bleeding? Immediately rule out vWD!+1
waterlooVit C def I thought was super tricky. My knee jerk reaction was oh easy bruising, bleeding from gums that's what it has to be. But yeah, I think low platelet is key here. +1
nafilnafPlatelet count would be normal in vWD because there's nothing wrong with the platelets themselves.+1
