Thymus

The thymus has nodules with cortex and medulla. Corpuscles of Hassall are scattered in the nodules.Corpuscles of Hassall (or thymic corpuscles) are the large red cells seen clearly in this higher magnification They are diagnostic of the thymus

Differential diagnosis:  Thymus can be confused with other lymphatic organs such as spleen, lymph node and tonsil. All have nodules except spleen with pulp. But thymus has distinct corpuscles of Hassall which others do not have and splenic pulp is a diagnostic feature for spleen.
