Hashimoto thyroiditis in Adult
There are 2 phenotypic forms: goitrous autoimmune thyroiditis and atrophic autoimmune thyroiditis. For both forms, lymphocytic infiltration is seen on pathology with concentrations of antibodies to thyroid peroxidase (TPO) and thyroglobulin (Tg) elevated in the serum.
Because symptom onset may be gradual, patients are initially asymptomatic but may present with a goiter in time. As the disease progresses, signs and symptoms of hypothyroidism such as bradycardia, weight gain, constipation, brittle hair, and fatigue become more apparent.
