Concurrence of marginal zone B-cell lymphoma MALT-type and Langerhans cell histiocytosis in a thyroid gland with Hashimoto disease

摘要

A 55-year-old woman presented with a clinical history of hypothyroidism and goiter with secondary obstructive symptoms, including dysphagia and stridor. On physical examination, the thyroid gland was diffusely enlarged, firm, with no pain on palpation, and no lymphadenopathy. The ultrasound study revealed a diffuse enlargement of the gland with no detectable calcifications. Laboratory tests were indicative of the Hashimoto's thyroiditis (HT).
