Essentials Acquired Glanzmann thrombasthenia (aGT) is generally caused by function‐blocking antibodies (Abs). We demonstrated a unique aGT case due to marked reduction of αIIbβ3 with anti‐αIIbβ3 Abs. The anti‐αIIbβ3 Abs of the patient did not inhibit platelet function but reduced surface αIIbβ3. Internalization of αIIbβ3 induced by the Abs binding may be responsible for the phenotype.
