They do not generally appear irregular, but may do so if other pathology is present (e.g. post-splenectomy). However, since the spherical form is the end of a what is often a progressive process, cells of intermediate appearance between biconcave disc and true sphere may be found. <g...")

These tend to be short, blunt, and are distributed relatively evenly across the cell. The appearances develop over time so there is a spectrum of forms. The cells initially resemble normal erythrocytes with subtle projections, these projections become increasingly clear in the mature echinocyte. Depending on the c...")
