Intrathyroid ectopic thymus.
The flow cytometry results are characteristic for thymocytes. Most of cells are CD4+&CD8+ as well as CD1a+, which is typical for common thymocytes. Some cells are CD4+ or CD8+ only, and they are likely late stage thymocytes. Most cells are negative for surface TCR (not shown here) and surface CD3. The expression of surface CD3 and TCR is variable, which indicates continuation of maturing.
