It is a bilobed structure divided into lobules by the connective tissue septa. Each lobule consists of a cortex and medulla. Most of the studies regarding early foetal histology of this organ are animal based. The present study has been undertaken to highlight some features regarding histogenesis of human foetal thymus.<\/p>\n<p style=\"text-align: justify;\"><strong>Materials and Methods<\/strong>: In the present study, 30 normal human stillborn\/aborted foetuses were studied. The obtained foetuses were fixed in 10% formalin. After proper fixation they were subjected to dissection. The obtained specimens were processed by standard paraffin block making procedure. Sections were taken and stained with haematoxylin &amp; eosin. The stained sections were examined under light microscopy using 10x and 40x optical magnifications and photographs taken.<\/p>\n<p style=\"text-align: justify;\"><strong>Results: <\/strong>At 12<sup>th<\/sup> week, capsule was thin and cortico-medullary differentiation not much prominent. Epithelial cells and lymphocytes were present. Hassall\u2019s corpuscles were very small and immature. Distinct lobulation was seen at 18<sup>th<\/sup> week with well differentiated cortex and medulla. The gland became more distinct from 21<sup>st<\/sup>week onwards with increased number of Hassall\u2019s corpuscles of various types. 29 week onwards the thymus gland revealed an adult histological picture.<\/p>\n<p style=\"text-align: justify;\"><strong>Conclusion<\/strong>: All structural changes viz cortico-medullary differentiation, lobulation and maturity of Hassall\u2019s corpuscles occurred within the first 18 weeks of gestation.<\/p>\n<p style=\"text-align: justify;\"><strong>KEY WORDS:<\/strong> Thymus, Hassall\u2019s corpuscle.<\/p>\n<p style=\"text-align: justify;\"><strong>REFERENCES<\/strong><\/p>\n<ol>\n<li style=\"text-align: justify;\">Ajita RK, Naranbabu Singh T H, Ibochouba Singh Y, Chandramani Singh L.
