We report a rare combination of variations in the upper limb of a human cadaver. Accessory flexor carpi ulnaris with absent palmaris longus was observed in the left forearm during routine dissection of a male cadaver. Variant vascular pattern was observed bilaterally. Brachial artery bifurcated at a higher level. Ulnar artery gave rise to persistent median artery (PMA) which pierced the median nerve and accompanied it deep into flexor retinaculum to terminate as two common palmar digital arteries. Superficial palmar arch was not formed as the PMA did not anastomose with either the radial or ulnar artery. Radial artery was small and deep palmar arch was mainly contributed by the deep branch of ulnar artery. Awareness of these coexistent variations in the forearm and hand is anatomically as well as clinically important in reconstructive hand surgeries.
