Diagnosis of KMP
Diagnosis of KHE is often made by clinical findings, imaging (usually MRI or ultrasound) and hematological findings alone17. Biopsy with histologic confirmation is the gold standard; however, biopsy is often difficult or dangerous due to the coagulopathy and clinical diagnosis must suffice. For atypical lesions, biopsy can be safely performed after administration of blood products such as platelets, fresh frozen plasma or cryoprecipitate.
