Spontaneous Unilateral Achilles Tendon Rupture With Corticosteroid Use for Microscopic Polyangiitis

Achilles tendon rupture is increasingly reported in patients treated with corticosteroid and fluoroquinolones. We report about a patient who sustained a spontaneous non-traumatic Achilles tendon rupture while he was taking oral corticosteroid for the treatment of microscopic polyangiitis (MPA). This patient ’ s tendon rupture was treated with a non-surgical approach because of his age, immunocompromised state and delay in presentation. The rupture healed gradually and his corticosteroid dose was weaned as the MPA improved. doi: http://dx.doi.org/10.4021/jmc1270e
