Kearns-Sayre syndrome (KSS) is a rare neuromuscular disorder. We report a case of a 14-year-old boy diagnosed and treated as myasthenia gravis for (4) years who was eventually diagnosed with KSS. He reported to us 3 years after initial presentation of mild drooping of eyelids with increased severity of ptosis, bilateral external ophthalmoplegia, and atypical retinitis pigmentosa. On multispecialty consultation, he was found to have right bundle branch block, wasting and weakness of limb muscles, and hearing loss. Sartorius muscle biopsy revealed ragged red fibres on trichrome stain. All these findings confirmed the diagnosis of Kearns-Sayre Syndrome (KSS). The take home message is to have a high index of suspicion for KSS when encountering cases of musculoskeletal disorders in subjects below 20 years of age in view of high morbidity and mortality associated with this syndrome
