Alkaptonuria (AKU) is a rare autosomal recessive disorder that is caused due to the deficient activity of homogentisate1, 2‐dioxygenase which results in increased levels of homogentisic acid (HGA) and its oxidized product benzoquinone acetic acid (BQA), which form polymerized deposits resulting in a bluish‐black discoloration of the cartilage as well as degeneration, inflammation and calcification of the tendons, ligaments and large joints and increased bone resorption. Ochronotictendinopathy most commonly affects the Achilles or patellar tendon leading to enthesopathy or spontaneous tendon ruptures. Here, we report a case of a 35‐year‐old male patient with a nontraumatic achilles tendon rupture without a previous diagnosis of ochronosis.
