Abstract
Chronic Hashimoto Thyroiditis (CHT) is the main cause of hypothyroidism. To report a series of patients with CHT. Retrospective analysis of a series of 27 men aged 38 +/- 14 years and 201 women aged 37 +/- 16 years, evaluated in the private offices of two of the authors. Fifty six percent of patients only had unspecific symptoms at the moment of consultation, 50% had a family history of thyroid diseases and only 21% of women had a previous history of goiter. Eighty one percent of patients had clinical or subclinical hypothyroidism, 62% had both antithyroglobulin and antithyroid peroxidase positive antibodies and 13% had both antibodies negative. Only 1.4% of patients had a normal thyroid ultrasound examination. Patients were treated with levothyroxine at a mean dosage of 75 microg/day and 53% achieved an adequate TSH level. Six often patients operated due to nodules had a papillary carcinoma. CHT should be sought in the general population, especially those with a family history of thyroid disease. Thyroid ultrasound is seldom normal in patients with CHT. Thyroid substitution should be monitored periodically to achieve adequate TSH levels.

Summary
Chronic Hashimoto Thyroiditis (CHT) is the main cause of hypothyroidism. Aim: To report a series of patients with CHT. 1.4% of patients had a normal thyroid ultrasound examination. Thyroid ultrasound is seldom normal in patients with CHT. La tiroiditis crónica de Hashimoto (TCH) es una enfermedad autoinmune y constituye la principal causa natural de hipotiroidismo. El diagnóstico de TCH se hace en relación a la palpación de un tiroides de tamaño normal o aumentado, de consistencia firme y gomosa, indoloro, de bordes netos, superficie irregular; falla funcional tiroidea clínica o subclínica o por la presencia de altos niveles de anticuerpos antitiroideos en sangre (antiperoxidasa, antitiroglobulina o ambos). El objetivo de nuestro trabajo fue dar a conocer las características demográficas, clínicas, de laboratorio, ultrasonográficas y de tratamiento de una serie clínica de pacientes evaluados por los autores
