Papillary thyroid microcarcinoma in a boy with Graves' disease: a case report and review of the literature.

ABSTRACT

A 16-years old boy with diagnosis of Grave's disease was treated with methimazole for one year before radical total thyroidectomy treatment due to persistence of clinical hormonal hyperthyroidism. Histological analysis revealed the presence of a papillary microcarcinoma. The management of Grave's disease in pediatric age is still under discussion. Therefore, close monitoring of the disease is required, as well as case-by-case tailored decision on how to manage treatment and when to perform the radical one, taking into account the association of Grave's disease with differentiated thyroid cancer in adults and the higher malignancy of thyroid cancer in childhood.
