Hypothyroidism occurs in about 4.6% of people (0,3% of them suffer symptoms and 4,3% suffer subclinical hypothyroidism). Chronic autoimmune thyroiditis is the most common type of thyroiditis and organ-specific autoimmune disease, and it's the most common cause of goiter and hypothyroidism in countries with enough iodine contribution on feed. The role of thyroid hormones is known in multiple organ systems, although many cases of hypothyroidism are asymptomatic. Usually patients consult for goiter, short stature and obesity. We report a 13-years-old teenager case who is a chronic autoinmune hypothiroidism affected, with a several multiorganic disease, including renal failure, anemia, acanthocytosis, and asymmetric septal hypertrophy cardiomyopathy; an unusual presentation to diagnose the chronic autoinmune thyroiditis nowadays. Every alteration is reversible and returns to the normal state with hormone replacement therapy.
