Macrothrombocytes (reticulated platelets). Reticulated platelets, sometimes called stress platelets, appear in destructive thrombocytopenia. Reticulated platelets are noticeably larger than normal mature circulating platelets; their diameter in peripheral blood smears exceeds 6 µm, and their MPV reaches 12-14 fL. Source: Elaine M.
