Background & objective: Liver being the largest abdominal organ, the knowledge of its normal and variant morphology is essential for the clinicians. The present study comprises the observations and analysis of the gross morphological variations and anomalies on the surface of the liver with respect to its shape, lobes, fissures and location of the gallbladder. Herein, we review, discuss and compare the literature on this study with our results. Methods: A total of 96 formalin-fixed adult human livers, irrespective of the sex, were studied over a period of four years. These livers were specifically observed for any variant or anomalous surface morphology. Results: The most common type of surface variation was accessory fissures (44.8%), followed by gall bladder fossa/ cystic notch (39.6%), fissure for ligamentum teres (28.1%), and shapes of caudate and quadrate lobes (24.1%). Interpretation & conclusion: Awareness of the anatomical knowledge of the presence of variant or anomalous surface features on the liver can contribute to the understanding of the underlying pathology and thus, helpful to the radiologists and surgeons for a favourable outcome.
