Non-Hodgkin lymphoma of the thyroid in a patient with hyperthyroidism.

Primary thyroid lymphoma is incredibly rare with an annual incidence of approximately 2.1 per million persons, accounting for 2% of thyroid malignancies. One of the only known risk factors is autoimmune thyroid disease, specifically Hashimoto's, although there have been a few cases of thyroid lymphoma associated with Graves' disease. Here, we present one such case of a patient with pre-existing hyperthyroidism who developed non-Hodgkin's lymphoma of the thyroid. The patient initially presented with rapidly progressing right-sided neck swelling. He was clinically and biochemically euthyroid with negative thyroid stimulating immunoglobulin, maintained on methimazole. Biopsy of the thyroid nodule with flow cytometry revealed non-Hodgkin lymphoma. Intervention included radiation therapy.

Bird Fancier's lung: An underdiagnosed etiology of dyspnea.

Bird Fancier's Lung is a type of hypersensitivity pneumonitis, an immunologically mediated lung disease due to repetitive exposure of air-borne avian antigen. This was first described in 1965 and is known as one of the most common causes of hypersensitivity pneumonitis. This case highlights this underdiagnosed etiology of dyspnea, disease presentation and exposure variability, and methods of diagnosis.

Strangulation-Induced Thyrotoxicosis in a Patient with Undiagnosed Underlying Graves' Disease.

Thyrotoxicosis is a constellation of symptoms including palpitations, tremors, agitation, and heat intolerance, caused by excess thyroid hormone. It can be life-threatening in its most serious form. We present a rare case of thyrotoxicosis provoked by mechanical trauma to the neck via strangulation in a young female with a history of self-resolving postpartum symptoms of hyperthyroidism one year prior, but no formal diagnosis of thyroid dysfunction. Although hyperthyroidism and posttraumatic stress have many similar features, thyroid storm is a life-threatening disorder that needs immediate intervention.
