Thyroid nodules are common and are frequently benign. Current data suggest that the prevalence of palpable thyroid nodules is 3% to 7% in North America; the prevalence is as high as 50% based on ultrasonography (US) or autopsy data. The introduction of sensitive thyrotropin (thyroid-stimulating hormone or TSH) assays, the widespread application of fine-needle aspiration (FNA) biopsy, and the availability of high-resolution US have substantially improved the management of thyroid nodules. This document was prepared as a collaborative effort between the American Association of Clinical Endocrinologists (AACE) and the Associazione Medici Endocrinologi (AME). Most Task Force members are members of AACE. We have used the AACE protocol for clinical practice guidelines, with rating of available evidence, linking the guidelines to the strength of recommendations. Key observations include the following. Although most patients with thyroid nodules are asymptomatic, occasionally patients complain of dysphagia, dysphonia, pressure, pain, or symptoms of hyperthyroidism or hypothyroidism. Absence of symptoms does not rule out a malignant lesion; thus, it is important to review risk factors for malignant disease. Thyroid US should not be performed as a screening test. All patients with a palpable thyroid nodule, however, should undergo US examination. US-guided FNA (US-FNA) is recommended for nodules > or = 10 mm; US-FNA is suggested for nodules < 10 mm only if clinical information or US features are suspicious. Thyroid FNA is reliable and safe, and smears should be interpreted by an experienced pathologist. Patients with benign thyroid nodules should undergo follow-up, and malignant or suspicious nodules should be treated surgically. A radioisotope scan of the thyroid is useful if the TSH level is low or suppressed. Measurement of serum TSH is the best initial laboratory test of thyroid function and should be followed by measurement of free thyroxine if the TSH value is low and of thyroid peroxidase antibody if the TSH value is high. Percutaneous ethanol injection is useful in the treatment of cystic thyroid lesions; large,symptomatic goiters may be treated surgically or with radioiodine. Routine measurement of serum calcitonin is not recommended. Suggestions for thyroid nodule management during pregnancy are presented. We believe that these guidelines will be useful to clinical endocrinologists, endocrine surgeons, pediatricians, and internists whose practices include management of patients with thyroid disorders. These guidelines are thorough and practical, and they offer reasoned and balanced recommendations based on the best available evidence.

We present a case of a malnourished 68-year old man with occult hypothyroidism who presented with malaise, pyrexia, tongue swelling, oral ulceration and dysphagia after a 6-month period of increasing lethargy and failing self-care. Severe necrotic oral ulcerative lesions were accompanied by cutaneous purpura, blood-filled blisters and bedsores. It was concluded that the patient's clinical condition reflected necrotizing stomatitis on a background of malnutrition with scorbutic skin lesions and hypothyroidism. The patient made a good recovery with scrupulous oral hygiene, debridement, intravenous metronidazole and nutritional support. Healing occurred with marked fibrosis and trismus, which has slowly improved with mouth-opening exercises. Necrotizing stomatitis is more commonly encountered in malnourished children in developing countries, and may subsequently result in devastating facial defects and death. Patients in the developed world with poor oral hygiene, malnourishment and immunosuppression are also at risk, but early diagnosis and treatment is life-saving and reduces subsequent disability.

The authors review the epidemiology, clinical manifestations, diagnosis and treatment of Pneumocystis jiroveci thyroiditis of 15 cases reported in the medical literature. Patients with acquired immunodeficiency disease syndrome were particularly at risk. P. jiroveci thyroiditis was diagnosed at autopsy as a part of disseminated infection in a substantial number of patients without clinical manifestations and laboratory evidence of thyroid dysfunction. Local signs and symptoms of infection were indistinguishable from other infectious thyroiditis and included neck enlargement with or without cervical pain, sometimes associated with dysphagia and dysphonia, and clinical and laboratory features of hypothyroidism. Antemortem diagnosis of fungal thyroiditis was made by direct microscopy and culture of a fine-needle aspirate in most cases. As most patients with P. jiroveci thyroiditis had disseminated Pneumocystis infection with a delay in diagnosis and treatment, the overall mortality was high. Pneumocystis jiroveci thyroiditis is rare but should be suspected in HIV-infected patients with CD4 count lower than 200 cells micro(-1) on prophylatic inhalatory pentamidine who present with neck enlargement with or without pain, and clinical and laboratory evidence of hypothyroidism.

An 82-year-old female patient with hypothyroidism and Hashimoto's thyroiditis noted three years ago to have a small asymmetric goiter (left > right). Nevertheless, a rapid growth of the thyroid over 3-6 months caused dysphagia and shortness of breath. Ultrasound and a thyroid gammagram showed an image consistent with multinodular goiter with a hyperfunctioning nodule in the right lobe. Due to the history of Hashimoto's thyroiditis and a rapid increase in size of the thyroid gland, diagnoses of thyroid lymphoma and anaplastic thyroid cancer were considered. Thyroidectomy was attempted at an outside facility to relieve compressive symptoms. Fine needle aspiration was insufficient for diagnosis, and the product of thyroidectomy confirmed the diagnosis of diffuse large B-cell lymphoma. A positron emission tomography/computed tomography scan was performed in our institution for staging, revealing nodal and extranodal metastasis. Chemotherapy using cyclophosphamide, vincristine and dexamethasone (COP modified) led to a dramatic response of the tumor and a complete resolution of compressive symptoms.

Lingual thyroid is a rare developmental anomaly. It is the result of failure of the thyroid to descend from the foramen caecum to its prelaryngeal site. Lithium is a known goitrogen, but has never been reported to cause symptomatic enlargement of the lingual thyroid. We describe a 40-year-old woman, who presented with a foreign body sensation and progressive dysphagia caused by an ectopic lingual thyroid tissue measuring 4 cm x 3 cm x 3.5 cm. She had been taking lithium for treatment of bipolar disorder and had hypothyroidism. Her symptoms were relieved after excision of the ectopic thyroid tissue.

We report an 11 year-old boy who presented with difficulty in swallowing without symptoms of hypothyroidism. The physical examination revealed a mass at the base of the tongue. The thyroid hormone profile showed a primary hypothyroidism (a serum TSH of 10.8 IU/mL with normal-low thyroxin of 6.0 microg/dL and low triiodothyronine of 57.8 ng/dL). Antithyroid antibodies were negative. The fiberoptic endoscopy showed a reddish mass, without evidence of haemorrhage or ulceration, confirmed as a well circumscribed, hypodense mass in the base of the tongue by computed tomography of the oropharynx and neck. Tc-99-pertechnetate scanning showed an abnormal area of uptake at the base of the tongue and no uptake in the normal thyroid location, concordant with an ectopic lingual thyroid gland. Levothyroxine in a suppressive dose was started that resulted in a reduction of the size of the mass and disappearance of dysphagia.

Impaired muscle function may be a predominant aspect of hypothyroidism and is virtually present in all patients with overt thyroid failure. Less common is the onset of hypothyroidism with clinical features mimicking a polymyositis. We have observed 3 patients, whose age ranged 63-68 years, presenting with muscle aches, cramps, proximal weakness and stiffness. Two patients had dysphagia. Serum creatine kinase (CK) and electromyography (EMC) were altered in two patients. Muscle biopsy showed type II atrophy, sporadic type I and type II grouping, "core-like" areas, and some myopathic changes such as central nuclei and muscle necrosis. No inflammatory changes were present. Immunohistochemistry of several muscle cytoskeletal proteins revealed increased desmin in "corelike" areas. Detection of serum thyroid hormone levels revealed very low triiodo-L-thyronine (T3) and thyroxine (T4), whereas thyroid-stimulating hormone (TSH) was greatly increased as well as serum anti-thyroglobulin, anti-peroxidase and anti-microsome antibodies. The patients were diagnosed having a hypothyroid myopathy due to Hashimoto thyroiditis. L-thyroxine treatment normalized clinical and hormone levels, but serum antibodies remained elevated. Muscle biopsy was fundamental to establish the correct diagnosis in our patients. Presence of over-expression of desmin in cores, as described in target lesions in neurogenic diseases, may suggest a nerve-mediated pathogenesis of hypothyroid myopathy.

Lingual thyroid gland is a rare clinical entity caused by failure of the gland's anlage to descend early in the course of embryogenesis. It may present with symptoms of dysphagia, upper airway obstruction, or even hemorrhage anytime from infancy through adulthood. Treatment of this disorder includes the use of exogenous thyroid hormone to correct the hypothyroidism and to induce shrinkage of the gland. When symptoms of obstruction or bleeding appear, ablative therapy by means of surgery or radioiodine is warranted. We report our experience with lingual thyroid gland and discuss elements of the diagnostic and therapeutic evaluation, with emphasis on the clinical findings, laboratory tests, and radiographic imaging studies.

Thyroid lymphoma is a rare disease which occurs mainly in elderly females. Most patients with thyroid lymphoma have Chronic Lymphocytic Thyroiditis (CLT), suggesting a role of chronic antigen stimulation in the development of the disease. We present two cases of thyroid Diffuse Large B-cell Lymphoma (DLBCL) diagnosed after surgery (subtotal thyroidectomy) by means of combined histology and immunohistochemistry (positive staining for CD-20) in two elderly female patients presenting at our institution for compressive symptoms (dysphonia in patient 1, dysphagia in patient 2) due to a gross neck mass. Fine-needle aspiration was compatible with lymphocytic thyroiditis in the first patient and was indeterminate in the second patient. The first patient had a long-lasting history of hypothyroidism due to CLT and was on L-thyroxine replacement therapy, whereas the second patient had normal thyroid function and negative thyroid autoantibodies. After surgery both patients underwent chemotherapy (cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) plus rituximab). At one-year follow-up both patients were disease-free. Thyroid lymphoma is an uncommon tumor which requires prompt diagnosis and combined management for a high rate of cure to be achieved.

Lingual thyroid is a rare embryological anomaly and originates from failure of the thyroid gland to descend from the foramen caecum to its normal eutopic pre-laryngeal site. The ectopic gland located at the base of the tongue is often asymptomatic but may cause local symptoms such as dysphagia, dysphonia with stomatolalia, upper airway obstruction and haemorrhage, often with hypothyroidism. Two cases are presented, one in a 62-year-old female and the other in a 42-year-old female, both of whom complained of sensation of a foreign body and progressive dysphagia and dyspnoea caused by ectopic lingual thyroid. Treatment was performed with a partial endoscopic removal and an external cervical approach, followed by substitutive hormone treatment, respectively. Diagnostic procedures and therapeutic options are discussed and a review has been made of reports of lingual thyroid appearing in the literature.
