Abstract
Background: Subacute thyroiditis (SAT) is a thyroid disease initiated by viral infection. Whether severe acute respiratory syndrome coronavirus 2 infection can cause SAT is unclear. This study investigated changes in the nationwide incidence of SAT during the coronavirus disease 2019 (COVID-19) pandemic. Methods: This is a retrospective, cross-sectional population-based study. Data regarding SAT and related viral diseases, including COVID-19, from 2017 to 2020 were collected from the National Health Insurance Service and Korea Disease Control and Prevention Agency databases. Results: In a total of 15,447 patients, 2484 men and 12,963 women diagnosed with SAT from 2017 to 2020 were included in this study. The incidence of SAT was significantly higher in 2020 than in 2017-2019 (8.30 vs. 7.27 per 100,000 persons, p < 0.001), while the incidence of SAT-related respiratory viral diseases, except for COVID-19, markedly decreased in 2020. The peak age of SAT incidence in 2020 was 50-59 years, and the women-to-men ratio was 5.4 (similar to that in 2017-2019). Corticosteroids were prescribed more often (72% vs. 58%, p < 0.001), and the prescription rate exceeding 1 month was significantly higher (45% vs. 40%, p < 0.01) in 2020 than in 2017-2019. Conclusions: The incidence of SAT increased in 2020 in association with COVID-19. A diagnostic approach to COVID-19 needs to be considered in patients with SAT during the COVID-19 pandemic.

Abstract
Subacute thyroiditis (SAT) is characterized by severe pain in the anterior aspect of the neck and tenderness is present during the thyroid gland's palpation. It is commonly caused by viruses including mumps, measles, rubella, coxsackievirus, influenza, and Epstein-Barr virus (EBV). Painless subacute thyroiditis is rare and can present as a fever of unknown origin (FUO). Our case reports an unusual case of SAT as our patient did not have any neck pain. Laboratory investigations show low thyroid-stimulating hormone (TSH), poor or no uptake of radioactive iodine by the thyroid, and elevated erythrocyte sedimentation rate (ESR). Clinicians should be aware that painless SAT can present as a fever of unknown origin.

Abstract
Subacute thyroiditis following vaccination is an uncommon presentation of thyrotoxicosis. As the world undertakes its largest immunisation campaign to date in an attempt to protect the population from COVID-19 infections, an increasing number of rare post vaccine side effects are being observed. We report a case of a middle-aged woman who presented with painful thyroid swelling following the second dose of the COVID-19 mRNA vaccine BNT162b2 (Pfizer–BioNTech) with clinical, biochemical and imaging features consistent with destructive thyrotoxicosis. Symptomatic management only was required for the self-limiting episode. Thyroiditis typically has a mild and self-limiting course and thus this observation should not deter people from vaccination, as COVID-19 infection has a far greater morbidity and mortality risk than thyroiditis.

Abstract
Subacute thyroiditis (SAT) is a thyroid disease of viral or post-viral origin. Whether SAT represents a complication of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still unclear. Our aim was to systematically review the literature to 1) explore the size of the literature about SAT in COVID-19 and 2) evaluate the clinical characteristics of SAT. PubMed/MEDLINE, Embase, and Scopus were searched until April 20, 2021. Original papers, case reports, and case series reporting SAT in COVID-19 patients were included. Authors and their country, journal, year of publication, COVID-19 and SAT clinical presentation, thyroid function, therapy, and follow-up data were extracted. Nineteen papers (17 case reports and 2 case series) were included, describing 27 patients, 74.1% females, aged 18 to 69 years. COVID-19 was diagnosed by nasopharyngeal swab in 66.7% cases and required hospitalization in 11.1%. In 83.3% cases, SAT occurred after COVID-19. Neck pain was present in 92.6% cases and fever in 74.1%. Median TSH, fT3, and fT4 were 0.01 mU/l, 10.79 pmol/l, and 27.2 pmol/l, respectively. C-reactive-protein and erythrocyte sedimentation rate were elevated in 96% of cases. Typical ultrasonographic characteristics of SAT were observed in 83.3% of cases. Steroids were the most frequent SAT therapy. Complete remission of SAT was recorded in most cases. In conclusion, the size and quality of published data of SAT in COVID-19 patients are poor, with only case reports and case series being available. SAT clinical presentation in COVID-19 patients seems to be similar to what is generally expected.

Abstract
Viral infections are frequently cited as a major environmental factor involved in subacute thyroiditis and autoimmune thyroid diseases This review examines the data related to the role of viruses in the development of thyroiditis. Our research has been focused on human data. We have reviewed virological data for each type of thyroiditis at different levels of evidence; epidemiological data, serological data or research on circulating viruses, direct evidence of thyroid tissue infection. Interpretation of epidemiological and serological data must be cautious as they don't prove that this pathogen is responsible for the disease. However, direct evidence of the presence of viruses or their components in the organ are available for retroviruses (HFV) and mumps in subacute thyroiditis, for retroviruses (HTLV-1, HFV, HIV and SV40) in Graves's disease and for HTLV-1, enterovirus, rubella, mumps virus, HSV, EBV and parvovirus in Hashimoto's thyroiditis. However, it remains to determine whether they are responsible for thyroid diseases or whether they are just innocent bystanders. Further studies are needed to clarify the relationship between viruses and thyroid diseases, in order to develop new strategies for prevention and/or treatment.

Aberrant somatic hypermutations in thyroid lymphomas. Leuk Res 2008; 33:649-54.

Abstract
To determine a possible role of aberrant somatic hypermutation (ASHM) in the pathogenesis of thyroid lymphoma (TL), mutational status of genes affected by ASHM, including c-MYC, PIM-1, PAX-5 and RhoH/TTF, was analyzed. Tumor specimens from 33 patients with thyroid B-cell lymphoma and 14 with chronic lymphocytic thyroiditis (CLTH), an autoimmune thyroiditis known to provide a basis for TL development, was examined. Mutations of at least one of these genes was detected in 16 of 33 (48.5%) patients with TL and in 2 of 14 (14.3%) CLTH. Occurrence of ASHM in PIM-1, RhoH/TTF, and c-MYC was a constant finding in follicular lymphoma (FL) (all of 11 cases) but not so frequent in diffuse large B-cell lymphoma (DLBCL) (4 (33.3%) of 12 cases) and Marginal zone B-cell lymphoma (MZBCL) (1 (10.0%) of 10 cases). ASHM activity is ongoing in most of FL and DLBCL because intraclonal variants were found. FL was also unique in its lower expression level of activation-induced cytidine deaminase, a main player in DNA-modifying processes during SHM, compare to DLBCL and MZBCL.

Abstract
To clarify whether Fas and Fas ligand (FasL) mutations are involved in the pathogenesis of Hashimoto's thyroiditis (HT), we examined the open reading frame of Fas and FasL in 21 cases. Mutations of Fas and FasL genes were detected in 8 (38.1%) and 1 (4.8%) of 21 cases, respectively. All but one of the Fas mutations were frameshift mutations, which affect the cytoplasmic region (death domain) known to be involved in apoptotic signal transduction and thus could be loss-of-function mutations. FasL mutation in one case was a 46-bp deletion from nucleotide 349 to 394, which corresponded to exon 2. Lack of exon 2 results in a frameshift, which generates a stop codon at residue 128. This mutant encodes the protein that contains only a part of the intracellular domain, thus the abnormal protein might not be expressed on the cell surface. The cells with Fas mutations were confined to the mantle zone and the germinal center, as determined by microdissection methods. These findings suggest that the cells with Fas mutations might accumulate in those areas and might be involved in the pathogenesis of Hashimoto's thyroiditis.

Abstract
Subacute thyroiditis is a well-recognized cause of transient thyrotoxicosis, resulting from a destruction injury to the thyroid. The pathogenesis of this condition is not completely understood and there is debate regarding the extent of the contribution of autoimmunity and external agents, such as infections, to this process. We present the first reported case of subacute thyroiditis in a patient who had been on chronic lithium therapy as well as long-term immunosuppression, with cyclosporin and prednisolone, following an allogeneic bone marrow transplant. We speculate that this case suggests a minimal role of autoimmunity in the development of subacute thyroiditis.

Abstract
Patho-epidemiological studies have shown that thyroid lymphoma (TL) develops in thyroid affected by chronic lymphocytic thyroiditis (CLTH). CLTH is categorized as an organ-specific autoimmune disease, in which activated B-lymphocytes secrete a number of autoantibodies. Because antigenic stimulation might be involved in the pathogenesis of TL, the variable region in heavy chain (V(H)) genes was characterized in 13 cases with TL and 3 with CLTH. Clonal rearrangement of the V(H) gene was found in 11 cases of TL, and cloning study with sequencing of complimentary determining region (CDR) 3 revealed the presence of a major clone in 4. Three of the 4 cases used V(H) 3 gene, with the homologous germline gene of V3-30 in two cases and VH26 in one case. A biased usage of V(H) 3 and V(H) 4 genes with the homologous germline gene of VH26 in V(H) 3 gene was reported previously in cases with CLTH. A high level of somatic mutation (1-21%, average 12%) with non-random distribution of replacement and silent mutations was accumulated in all cases. The frequency of the occurrence of minor clones ranged from 29-44% per case, indicating the presence of on-going mutation. DNA sequencing of immunoglobulin V(H) gene suggests that TL develops among activated lymphoid cells in CLTH at the germinal center stage under antigen selection.

Abstract
Patho-epidemiological studies have shown that thyroid lymphomas (TL) develop in thyroids affected by chronic lymphocytic thyroiditis (CLTH). Cytokines produced in CLTH might play a pivotal role for lymphomagenesis, because previous reports indicate an important role of cytokines in lymphomagenesis. We examined the expression of interleukin-7 (IL-7), a pleiotropic cytokine that acts mainly on cells of the hematolymphoid system, and IL-7 receptor (IL-7R) in both TL and CLTH by RT-PCR. IL-7-specific transcripts were detected more frequently in TL than in CLTH lesions (p < 0.01). IL-7 expression was higher in TL than in CLTH. IL-7R and the common gamma chain were expressed in all but one TL and in all CLTH lesions, in similar levels. We established the sensitive in situ hybridization (ISH) method for detection of IL-7. ISH for IL-7 revealed cytoplasmic signals among cells in the germinal center and mantle zone of lymphoid follicles and interfollicular areas in the TL and CLTH lesions. In the lymphomatous areas of TL, similar numbers of scattered large and small lymphoid cells expressing IL-7 were found. The number of IL-7-expressing cells counted in 10 fields in TL (119.4 +/- 10.6 cells) was significantly higher than found in CLTH lesions (43.1 +/- 4.6) (p < 0.001). These findings suggest a pathogenetic role for IL-7 in the development of TL. ISH showed that the germinal center cells, interfollicular cells, and lymphoma cells expressed IL-7R, but mantle zone cells did not. Because lymphoid cells in lymphoid follicles and the interfollicular area formed in CLTH expressed IL-7, TL cells might proliferate via their own IL-7 and IL-7R, and via IL-7 from reactive lymphoid cells.

Abstract
A broad range of disorders can cause inflammation of the thyroid gland. True thyroid infections are rare and can result from a variety of microorganisms, of which bacteria are the most common. Other rarer pathogens include fungi, parasites, and viruses. Gram-positive bacteria, especially staphylococci, predominate as causative agents in adults and children. In immunocompromised patients, opportunistic pathogens have been isolated. Most infections in adults occur as a result of hematogenous or lymphatic seeding of the thyroid gland. In children, congenital anomalies can lead to thyroid infection and require surgical correction to prevent recurrence. Fine-needle aspiration of the thyroid is usually required to identify the infecting agent, and prolonged antimicrobial therapy with or without surgical drainage is the cornerstone of management. This review outlines the pathogenesis, microbiology, diagnosis, and management of infectious thyroiditis in adults and children and compares this disorder with other, more common causes of thyroid inflammation.

Abstract
Patho-epidemiological studies showed that thyroid lymphoma (TL) arises in inflammatory lesions of chronic lymphocytic thyroiditis (CLTH). Replication error (RER) is found in inflammatory lesions and associated cancer, suggesting that chronic inflammation could be a risk factor for neoplastic development through causing RER. To clarify whether RER is involved in the pathogenesis of TL, we examined the microsatellite instability (MSI) in 9 cases with CLTH and 19 with TL, including 10 diffuse large B-cell lymphoma (DLBL), 4 follicle center cell lymphoma, 3 marginal zone B-cell lymphoma of extranodal (MALT) type, and 2 lymphoplasmacytic type. Sixteen distinct microsatellite repeats were analyzed. Mutations of p53 and k-ras genes were also examined. When alterations at 2 or more microsatellite loci were judged as positive, only 5 DLBL cases exhibited MSI. The frequency of MSI in DLBL was significantly higher than that in other types of TL and CLTH (P < 0.05). Four of 19 cases (21.1%) showed point mutation of the k-ras gene. The k-ras mutations occurred in the cases with DLBL with RER, and four of five cases with RER had a k-ras mutation, indicating a close association between RER and k-ras mutation. p53 mutations were not found in the CLTH. Two of 19 TL cases showed mutations of p53 gene. There was no significant association between RER and p53 mutation. These findings indicate that genomic instability contributes to the progression of TL from low grade to high grade, but not to the development of low grade lymphoma in CLTH lesions.

Abstract
Intercellular adhesion molecule (ICAM-1), a ligand for lymphocyte function-associated antigen-1 (LFA-1), plays an important role in a variety of immune-mediated mechanisms such as lymphocyte attachment to cultured Graves' thyroid cells. We report the detection of a soluble form of the ICAM-1 molecule (sICAM-1) in sera from patients with Graves' disease (GD) and other thyroid disorders. The mean (+/- SD) sICAM-1 concentration in 28 euthyroid control subjects was 1931 +/- 681 pmol/L. The mean sICAM-1 concentration in 25 untreated hyperthyroid patients with GD was significantly elevated (3065 +/- 890 pmol/L), and decreased significantly (2489 +/- 845 pmol/L) after treatment with antithyroid drugs and/or 131I. Of 14 GD patients who had been in remission following administration of antithyroid drugs, 12 had recurrent disease. In 10 of the 12 patients in whom GD recurred, the sICAM-1 concentration (3807 +/- 796 pmol/L) increased significantly. The mean sICAM-1 concentration in patients with hypothyroidism due to chronic thyroiditis (n = 15:2895 +/- 569 pmol/L) was significantly elevated over that of control subjects, and not different from untreated hyperthyroid patients. The mean sICAM-1 concentration in patients with subacute thyroiditis (n = 13: 3036 +/- 441 pmol/L) was significantly elevated, while the mean sICAM-1 concentration in patients with nodular goiter (n = 10: 2318 +/- 490 pmol/L) was within the normal range. These results indicate that mean serum sICAM-1 concentration was significantly elevated in patients with untreated GD, and it decreased after treatment and increased at the time of recurrence. Therefore, the elevated serum concentration of sICAM-1 in patient with GD probably reflects ongoing immune processes.

Abstract
The causal role of Epstein-Barr virus (EBV) in the development of B-cell lymphoma, especially in immunocompromised individuals, has been suggested. The purpose of the present study was to evaluate an association of EBV with thyroid lymphoma (TL) and chronic lymphocytic thyroiditis (CLTH) which is known to play an important role in the development of TL. Thirty cases with TL and 28 with CLTH were studied for presence or absence of EBV genome in the lesions using the polymerase chain reaction (PCR) and the in situ hybridization method. EBV genomes were detected by PCR in one and two cases with CLTH and TL, respectively. Subtyping of EBV genome was possible in one TL case showing B-type in EBNA-2 coding region. In situ hybridization revealed positive signals in the nucleus of lymphoma cells, which also expressed latent membrane protein-1. The present findings indicate that activation of EBV in TL is not common.

Abstract
A 44-year-old woman came to medical attention with right thyroid lobe enlargement and weight loss. Thyroid scan and ultrasound demonstrated a nodule in the right thyroid lobe; a right hemithyroidectomy was performed. Histologic examination documented granulomatous and lymphocytic thyroiditis associated with a follicular adenoma. No inflammation was apparent within the adenoma. The parallels between granulomatous thyroiditis and lymphocytic thyroiditis, including presumed viral initiation and deranged immunologic function, suggest that granulomatous thyroiditis may evolve into chronic lymphocytic thyroiditis; this case may be an example of such a transition. It is proposed that thyroid follicular adenomas have different antigenicity, which may account for the conspicuous absence of inflammation within the tumor.

Abstract
Hashimoto's thyroiditis (struma lymphomatosa), first described by Hashimoto in 1912, is an autoimmune inflammation of the thyroid commonly affecting middle-aged women. Histologic features of Hashimoto's thyroiditis (HT) include diffuse infiltration of lymphoid cells usually with formation of lymphoid follicles, varying degrees of fibrosis, oxyphilic change or squamous metaplasia in the epithelial cells. When the presence of focal lymphocytic infiltration is assumed to be an adequate criterion for diagnosis of autoimmune thyroiditis, the incidence appears to be as high as 16-23% in elderly females. An etiologically important role of HT in the development of thyroid lymphoma had been postulated, and recently, this was confirmed by epidemiological studies. In this article, a brief review of HT is given, together with results of our studies on thyroid lymphoma, and a discussion in the light of the pertinent literature. Immunologic and immunohistologic studies revealed that all of the thyroid lymphomas were of the B-cell type. Malignant lymphomas developing in patients with other autoimmune diseases such as Sjögren syndrome and rheumatoid arthritis have also been reported to be B-cell derived. Therefore it is suggested that immune deficiency is a causal factor for B-cell lymphoma.

Abstract
Three women presented with malignant thyroid lymphoma (stage IE and IIE) that was associated with Hashimoto's thyroiditis. Each patient was treated with combination chemotherapy (two patients received cyclophosphamide/adriamycin/vincristine/prednisolone, one patient received methotrexate/adriamycin/cyclophosphamide/vincristine/prednisolone/ble omy cin) as the primary mode of therapy. One patient underwent incomplete excisional surgery and received chemotherapy. A complete clinical and radiological remission was achieved in all patients, in spite of evidence of extensive extrathyroidal invasion in two patients. The chemotherapy was well-tolerated, producing minimal toxicity. All the patients are alive and remain free of tumour recurrence 26 to more than 38 months after diagnosis. These results suggest that combination chemotherapy can be employed successfully as a single modality treatment for stage IE and IIE thyroid lymphomas, even when significant extrathyroidal invasion is present. The treatment of thyroid lymphoma is reviewed with emphasis on the potential role for chemotherapy as the primary modality.

Abstract
Autoimmune thyroiditis, most notably Hashimoto's thyroiditis, appears to be increasing in prevalence and is now more easily detected by sensitive laboratory tests and more invasive procedures such as fine needle aspiration. During the last decade, marked progress has been made in the understanding of these diseases. There is a greater awareness of the interaction between the humoral and cell-mediated arms of the immune system in autoimmune thyroiditis. Recent studies implicate a subpopulation of suppressor T lymphocytes which have an antigen-specific defect, resulting in their suboptimal interaction with the helper T lymphocytes and subsequent autoimmune manifestations. There is some evidence that thyroid epithelial cells which inappropriately express HLA-DR may enhance presentation of thyroid antigens to the immune system, possibly significant in the initiation or enhancement of the autoimmune response. The presence of various antithyroid autoantibodies allows the use of laboratory assays to confirm the clinical diagnosis and predict the results of treatment. There appears to be predisposing genetic factors in the development of autoimmune thyroiditis, with some geographical and racial differences. Environmental factors, most notably dietary intake of iodine, have also been implicated in the pathogenesis of Hashimoto's thyroiditis. Several animal models have been developed addressing such issues. Ongoing studies in the areas of postpartum thyroiditis and childhood thyroiditis are helpful in clarifying their relationship with Hashimoto's thyroiditis. Graves' disease and postpartum thyroiditis are being investigated as possible causes of postpartum depression. The association of Hashimoto's thyroiditis and carcinoma of the thyroid gland is still controversial, but its relationship with malignant lymphoma is now well accepted. Thus, although the pathogenesis of autoimmune thyroiditis remains elusive, there has been significant refinement of the clinical diagnosis, and immunological abnormalities of specific intrathyroidal lymphocytes have been identified. Hopefully, these new areas of knowledge will assist in the treatment of these diseases and in the prevention of the development of malignant lymphomas of the thyroid gland.

Abstract
Malignant lymphomas developing in tissue affected by a long-standing severe inflammatory process of nonautoimmune nature are presented. Two men and a woman aged 50, 58, and 73 years, were admitted after 22 to 30 year histories of pyothorax resulting from artificial pneumothorax for the treatment of pulmonary tuberculosis or tuberculous pleuritis. The diagnoses at admission were chronic pyothorax associated with a lung mass. Microscopically, tumors diffusely or locally proliferated with thickened pleura were present. A histologic examination showed that all the tumors were diffuse non-Hodgkin's lymphomas (NHL) of immunoblastic type with (one case) or without (two cases) plasmacytoid differentiation. Immunohistochemistry on paraffin sections revealed restricted expression of immunoglobulin light chains in one case showing plasmacytoid differentiation. A review of the literature showed that malignant lymphomas of this type have been reported exclusively from Japan but never from Western countries.

Abstract
Prognostic factors in 79 patients with malignant lymphomas involving the thyroid gland were analyzed. These patients suffered from progressively enlarging goiter with over 6 months duration in 60% of patients. The age at operation ranged from 16 to 80 years (median, 58 years). Male to female ratio was 1:1.8. Serum tests for antithyroid antibodies were positive in 83% of the patients, who also showed histologic evidence of chronic lymphocytic thyroiditis. Histologically, 52 cases (66%) were germinal center cell tumors with follicular or follicular and diffuse pattern in 9 cases. By the Working Formulation, 5-year survival rate of immunoblastic type (IBL) (13%) was much poorer than those of intermediate (79%) and low grade cases (92%) (P less than 0.001). The cases of IBL usually had a goiter of short duration, and frequently presented as advanced disease.

Abstract
Hypothyroidism may be self-limiting or may progress to thyroid failure, depending on the cause. Thus, diagnosis of the underlying disorder is extremely important. Once the diagnosis is established, the origin and cause of hypothyroidism must be identified. A careful history and physical examination, routine laboratory tests, and demonstration of antithyroid antibodies will ordinarily lead to the correct diagnosis. Self-limited disorders require little or no therapy. Progressive disease is treated with a thyroid hormone preparation. Myxedema coma is an endocrine emergency that requires prompt treatment of both the metabolic complications and any intercurrent illness.

Abstract
Four cases of thyroid lymphomas are presented showing curious histologic difficult to distinguish from severe lymphocytic thyroiditis by routine histologic study alone. The age of the patients ranged from 39 to 63 years. Three female patients suffered from autoimmune (lymphocytic) thyroiditis for 2 to 20 years until the present illness. A male patient had no history of thyroiditis. Rapid growth of struma in these patients suggested an evolution of malignant lymphomas. Histologic study results showed that small atypical lymphoid cells with slightly irregular and indented nuclear contour surrounded randomly distributed secondary follicles as a wide mantle. Immunohistologic staining showed that these atypical small lymphoid cells expressed surface properties intermediate between mantle-zone lymphocytes and germinal center cells with a restricted expression of kappa chain in three cases. Stages of tumors were stage I in three cases and stage II in one case. The findings demonstrated were intermediate lymphocytic lymphomas of the thyroid.

Abstract
The microscopic slides of 16 patients who underwent bilateral subtotal thyroidectomy for hyperthyroid Graves' disease were reviewed and classified into three groups: I, Hashimoto's thyroiditis; II, Graves' disease; and III, both Hashimoto's thyroiditis and Graves' disease. Three patients were classified as group I, 10 as group II, and three as group III. In 38% of the patients with clinical Graves' disease the histologic evidence of Hashimoto's thyroiditis could be found either alone or in combination with histologic evidence of Graves' disease (groups I and III). One patient in group I, four in group II, and three in group III had infiltrative ophthalmopathy (50% of total). Hyperthyroid Graves' disease, Graves' ophthalmopathy, and Hashimoto's thyroiditis can occur all together, in duads, or individually at a specific time in a patient's life.

Abstract
Head and neck surgeons are involved in the diagnosis and therapy of thyroid disease with increasing frequency. The surgical techniques utilized for the management of thyroid disease are well known by most head and neck surgeons and will not be discussed in this paper. It is the head and neck surgeons' knowledge of the physiology, medical disorders, and the proper evaluation of the patient with thyroid disease that is most open to criticism. This paper reviews thyroid physiology, basic tests used to assess thyroid function in health and disease, thyroiditis, thyroid carcinomas, and nodules of the thyroid gland. The signs, symptoms, laboratory findings, and the methods of medical and surgical therapy are discussed for each of these disorders. The supplement is not intended to provide expertise, but will provide a general and basic knowledge of thyroid disease.

On radioisotope scanning, thyroid nodules present one of five characteristic patterns. A "cold" nodule is most likely to be malignant and often necessitates surgery and functional ablation. However, any nodule that is growing and insuppressible probably should be removed.

Abstract
The clinical and pathologic findings for 35 patients with malignant lymphoma presenting in the thyroid are reviewed. The lymphomas tended to occur in females with a median age of 65 years and clinically were manifested by a mass in the neck. The majority of patients were euthyroid and thyroid scans demonstrated cold nodules. In none of the patients was there clinical suspicion of lymphoma prior to surgery. Thirty-four of the cases were histiocytic lymphomas; the one exception; a patient with nodular poorly differentiated lymphocytic lymphoma, had histiocytic lymphoma in a subsequent biopsy of the soft tissues of the neck. Although classified as histiocytic, the lymphomas had the histologic and ultrastructural features of transformed lymphocytes or immunoblasts. Lending possible additional credence to the immunoblastic nature of these lymphomas was the histologic documentation of chronic lymphocytic thyroiditis in all 27 cases where residual thyroid parenchyma remained. This relationship suggests possible evolution of thyroid lymphomas from chronic lymphocytic thyroiditis and probably is analogous to the malignant lymphomas developing in other altered immune states, including Sjogren's syndrome. In the current study the overall 5-year survival was 54%. Patients under age 65, without local soft tissue extension or regional lymph node involvement, and with stage I disease survived the longest; a nodular histologic pattern also appeared to favorably influence the prognosis. Improved staging procedures and newer modes of therapy appear essential, particularly for those patients with clinical stage II disease and with local extension to soft tissues.
