In most of the cadavers procured for the dissections in the department of anatomy belongs to male adult cadavers, which were devoid of active thymus gland and often the gross features of this gland was ignored because of its remnants were found with variable degree of shape and sizes. During dissections in most of the cadavers we have often noticed the morphology of most thymus remnant from simple flat mass to a well defined solid mass of thymic tissue. To test our curiosity on microscopic studies we have noticed features like, abundant number of iscrete lymphocytes along with Hassall?s corpuscles were appreciated under hematoxylin and eosin staining. The thymus being a central lymphoid organ develops from endoderm of third pharyngeal pouch along with the parathyroid gland. It remains active till the age of 14 years and later shows gradual inclination towards its involution as conventionally it is believed to be an involuting organ with advancing age. Thymus being an important immune competent organ which has created a curiosity regarding its changes from advancing age to number of invasive and non invasive experimental studies, such interesting facts were considered to drag the attention of involuting organ.
