The liver is the largest wedge‐shaped gland in the human body. Anatomically it is divided into right lobe and left lobes with quadrate & caudate lobes. The congenital abnormalities of human liver are rare and these are rarer than almost any other organs of the body. Various congenital abnormalities of the liver as agenesis of its lobes, absence of its segments, deformed lobes, decrease in size of lobes, lobar atrophy, hypoplastic lobes, and transposition of the gall bladder, extra caudate lobe and Riedel's lobe have been reported by various researchers. The quadrate lobe is an area of the liver situated on the under surface of the right lobe, bounded in front by the anterior margin of the liver; behind by the porta hepatis; on the right, by the fossa for the gall‐bladder; and on the left, by the fossa for the umbilical vein. It is oblong in shape, its antero‐posterior diameter being greater than its transverse. Methodology & Results Accessory quadrate lobe has been observed towards the left end of quadrate lobe, beside ligamentum teres in our routine dissections. Its shape was Triangular in shape with its dimensions of length – 3.4 cm from its apex to base, thickness 0.9 cm, base – 1.8 cm. Conclusion These developmental anomalies of liver may cause confusion to clinicians during procedures like biopsy, transplantation, and lobectomies. So finding of this new variant under unique configuration of this lobe assumes more importance to anatomists including morphologists, and its knowledge may be of immense use to clinicians in the diagnosis and management of hepatic diseases and to embryologists for new developmental defect. Therefore, it is worth reporting as a new variant. Support or Funding Information AMERICAN ASSOCIATION OF ANATOMIST(AAA)
