Gray platelet syndrome (GPS) is a rare inherited disorder characterized by the absence of α-granules and their constituents. It may be present with thrombocytopenia and bleeding tendency. Platelets have a large and gray appearance under light and electron microscope. A 19-year old female patient with her second relapse acute lymphoblastic leukemia had to be consolidated with allo-hematopoietic stem cell transplantation (HSCT) after achieving remission with induction chemotherapy. The only available and one mismatch compatible donor was her brother, who was previously diagnosed as GPS. Allogeneic HSCT was performed from her brother in spite of GPS, and successful neutrophil and platelet engraftment achieved at the 12th and 42nd day of reinfusion, consecutively. The engrafted and circulating thrombocytes were large and gray and had little or no α-granules under electron microscope. The patient was well with no major bleeding event and increased need for thrombocyte replacement until developing bronchiolitis obliterans organizing pneumonia and respiratory distress syndrome. Thereafter death occurred. This is the first case of successful thrombocyte engraftment with documented gray thrombocyte megakaryopoiesis after allogeneic HSCT from a GPS donor. The only noteworthy issue was the slight prolongation of engraftment.
