We report a 22 years old girl who presented with diarrhea and symmetrical lower limb muscular weakness. Patient had short stature as well as refractory iron deficiency anemia. Her reports showed a positive anti transglutaminase IgA, and duodenal mucosal villous atrophy thereby establishing the diagnosis of celiac disease. Moreover, her muscle enzymes were also raised along with abnormal electromyography contributing to diagnosis of myositis secondary to celiac disease. Coexistence of both disorders in a patient provided evidence to the fact that both share an autoimmune etiology. Keywords: Celiac disease, Myositis, Short stature.
