title: T-cell lymphoblastic lymphoma in a child presenting as rapid thyroid enlargement.
abstract: The majority of lymphomas of the head and neck in children present as an enlarged cervical lymph node; however, malignant lymphoma arising from the thyroid gland is extremely rare. We report a case of a 12-year-old child who was admitted to our hospital because of a history of rapidly progressive anterior neck swelling. Histopathological studies revealed this case to be T-cell lymphoblastic lymphoma. We performed chemotherapy and the patient has kept recurrence-free survival for 18 months after the beginning of the treatment. This is the 2nd case of T-cell lymphoblastic lymphoma in the thyroid gland in a child.
