Abstract
Celiac disease (CD) is an autoimmune small intestinal mucosal disorder that often presents with diarrhea, malabsorption and weight loss. Often, one or more associated endocrine disorders may be associated with CD. For this review, methods involved an extensive review of published English-language materials. In children and adolescents, prospective studies have demonstrated a significant relationship to insulin-dependent or type 1 diabetes, whereas in adults, autoimmune forms of thyroid disease, particularly hypothyroidism, may commonly co-exist. In some with CD, multiple glandular endocrinopathies may also occur and complicate the initial presentation of the intestinal disease. In others presenting with an apparent isolated endocrine disorder, serological screening for underlying subclinical CD may prove to be positive, particularly if type 1 diabetes, autoimmune thyroid or other autoimmune endocrine diseases, such as Addison’s disease are first detected. A number of reports have also recorded hypoparathyroidism or hypopituitarism or ovarian failure in CD and these may be improved with a strict gluten-free diet.

Abstract
Primary thyroid lymphoma is a rare disease that continues to produce diagnostic and therapeutic dilemmas. There was great difficulty in distinguishing thyroid lymphoma from anaplastic thyroid carcinoma but, because of new immunocytochemical staining techniques and increased cytopathologic knowledge, our ability to diagnose thyroid lymphoma has improved drastically over the past decade. Surgery that was once the mainstay of treatment for this disease, now plays a minimal role. Current treatment regimens for primary thyroid lymphoma consist of chemotherapy (cyclophosphamide, doxorubicin, vincristine, and prednisone) and external beam radiation. The overall and distant relapse rates have been shown to be significantly lower in those patients receiving combined modality therapy compared to chemotherapy or radiation alone. Although the role of surgery has changed over time, it continues to play an important role, especially in confirming diagnoses through open biopsies, potentially providing local control in the more indolent subtypes, and may play a role in the palliation of symptoms for large obstructive lymphomas. The evolving classification of extranodal lymphomas has brought about a better understanding of the biologic behavior of these tumors. Most thyroid lymphomas are B-cell origin, with six different histologic subtypes, but there appears to be two distinct clinical and prognostic groupings of these rare tumors. The more indolent lymphomas are the subgroup of mucosa-associated lymphoid tissue (MALT) lymphomas comprising approximately 6% to 27% of thyroid lymphomas. This subgroup, when localized to the thyroid (stage IE), responds well to total thyroidectomy or radiation with a complete response rate of more than 90%, leading some authors to recommend surgery as primary therapy in the treatment of localized MALT lymphomas. Therefore, surgery as a primary treatment for thyroid lymphomas would only be recommended under ideal conditions, such as MALT subtype stage IE only, and completely resectable with minimal morbidity. Unfortunately, this scenario is rarely the case. The more common subtype, comprising up to 70% of cases, is diffuse large B-cell lymphoma. This subtype appears to have the most aggressive clinical course with almost 60% of these tumors diagnosed with disseminated disease. Up to 40% of all diffuse large cell lymphomas appear to have undergone transformation from a MALT lymphoma, but they behave in a similar fashion to diffuse large cell lymphomas. Treatment for these tumors should include chemotherapy and radiation. The overall 5-year survival for this aggressive group is less then 50%. Surgery is rarely beneficial in diffuse large cell lymphoma and the mixed large cell subtypes because the disease is generally disseminated and surgical excision of all disease is not possible or associated with increased morbidity. However, there may be a role for palliative surgical debulking to alleviate obstructive symptoms while the patient is undergoing standard chemotherapy and radiation.

Abstract
Non-Hodgkin's lymphoma presenting in the thyroid gland is uncommon. A review of the King Faisal Specialist Hospital and Research Centre (KFSH & RC) experience was performed to assess treatment outcome and prognostic factors in this rare extranodal presentation of localized lymphoma. Sixty patients treated at KFSH & RC between 1975 and 1995 were identified, and their records were reviewed retrospectively. Eight patients who had stage III or IV disease, low grade, or did not complete their prescribed treatment were excluded from the study. There were 38 female and 14 male patients with a median age of 59.5 years at the time of diagnosis (range: 10-87 years). Thirty-five of the 52 patients underwent diagnostic partial or total thyroidectomy at other institutions based on a preoperative assumption of thyroid carcinoma. All 52 patients had non-Hodgkin's lymphoma of intermediate (94%) or high (6%) grade. Detailed staging was carried out in all patients; 16 patients (31%) had disease confined to the thyroid gland (stage IE), whereas 36 (69%) had associated disease in cervical lymph nodes and/or the mediastinum (stage IIE) disease. All patients were treated with curative intent. A total of 18 patients (35%) were treated with a single-modality treatment--radiotherapy alone in 2, chemotherapy alone in 13, and surgery alone in the remaining 3 patients. The majority of patients (34/52; 65%) were treated with a combined-modality approach. The overall relapse-free survival (RFS) and overall survival (OS) at 5 years were 72% and 88%, respectively. There were no significant differences in outcome between those treated with single-modality and those with combined-modality therapy. A univariate analysis showed that the presence of mediastinal lymph node involvement was the most important prognostic factor affecting both RFS and OS. Patients with Hashimoto thyroiditis and without "B" symptoms were found to have a significantly higher RFS without influence on the OS. However, patients who had a good performance status (PS) of 0, 1, and 2 were found to have a significantly higher overall survival in comparison to those with poor performance status. Age, sex, stage, histology, lactic acid dehydrogenase level, tumor bulk, and the treatment modality were not found to correlate with RFS or OS. Mediastinal involvement and PS were found to be the most important independent prognostic factors influencing RFS and OS.

Abstract
The pathological and clinical features were reviewed of all primary non-Hodgkin's lymphomas (NHL) of the thyroid gland diagnosed between 1973 and 1992 in the population (1.1 million) served by the Nottingham and North Nottinghamshire Health Authorities. Of the 43 patients with histologically proven NHL, three had low grade mucosa associated lymphoid tissue (MALT) lymphomas (Stage IEA, 2; Stage IIEA, 1), 35 had intermediate or high grade lymphomas, Stage IEA or IIEA (intermediate MALT, 2; high grade MALT, 14; B-cell diffuse centroblastic, 17; anaplastic large cell (Ki-1) of null cell type, 1; high grade unclassifiable, 1), and one had unclassifiable NHL Stage IIEA. One patient had Stage IIIEA disease (high grade MALT) and three had stage IVA disease (high grade MALT, 2; B-cell diffuse centroblastic, 1). The median age was 68 years (range 45-86) with a female: male ratio of 6:1. For the 35 patients with intermediate or high grade thyroid NHL (Stages IEA and IIEA) the 5- and 10-year cause specific survival was 60%. The 21 patients treated between 1985 and 1992 initially with chemotherapy (except stage IEA (< 5 cm diameter) had a 5-year cause specific survival of 69% (95% CI 48-90) compared with 46% (95% CI 19-73) for the 14 patients treated between 1973 and 1984 with initial radiotherapy (Chi 2 = 1.62). The survival of those patients with intermediate or high grade MALT lymphomas was not significantly greater than of those patients with B-cell diffuse centroblastic NHL.

Abstract
Primary non-Hodgkin's lymphoma of the thyroid is predominantly a disorder of elderly females. Most patients present with limited disease and receive local irradiation. Presentation with advanced disease is uncommon and, consequently, bone marrow examination is not always done. We report a patient with primary thyroid lymphoma who had bone marrow infiltration at presentation and discuss the importance of this investigation in management.

Abstract
We describe the clinical aspects of primary thyroid lymphoma, particularly diagnostic procedures and successful therapy based on our observation of 119 patients with primary thyroid lymphoma. Thyroid lymphoma occurred exclusively in the thyroid gland of patients with Hashimoto's thyroiditis as a rapidly growing mass in the thyroid gland. Therefore, progressively enlarging goiter and compression symptoms were the most common clinical manifestations. A significant number of patients in our series had subclinical hypothyroidism (14%) or overt hypothyroidism (27%) because of the coexistence of Hashimoto's thyroiditis. Whenever thyroid lymphoma is suspected, we recommend an ultrasound scan of the thyroid gland and fine needle aspiration biopsy as initial diagnostic procedures. Thyroid ultrasound showed characteristic asymmetrical pseudocystic pattern in 43 of the 46 patients (93%), and thyroid cytologic examination showed abundant monomorphic infiltration of lymphoid cells. Among 83 patients who underwent fine needle aspiration biopsy, 65 patients (78.3%) were diagnosed correctly and 10 patients (12%) had borderline cytologic results. Thus, 90% of patients with thyroid lymphoma were diagnosed or the diagnosis suspected based on fine needle aspiration biopsy. To confirm the diagnosis of lymphoma histologically and to determine the degree of malignancy, open biopsy taking 2-3 g tissue should be done for all cases. Treatment of thyroid lymphoma does not require resection of all lymphoma tissue or total thyroidectomy. Our successful treatment is radiation therapy combined with six courses of CHOP chemotherapy (cyclophosphamide, adriamycin, vincristine, prednisolone). This mode of therapy improved the 8-year survival rate to nearly 100% regardless of the histological type of malignancy.

Abstract
Malignant thyroid lymphoma is an uncommon form of thyroid cancer which most commonly presents in elderly women. Most patients demonstrate a rapidly enlarging mass and may show tracheal deviation on chest roentgenogram. Radioisotopic scanning of the thyroid often demonstrates a “cold” or “cool” process of decreased uptake in the affected area. There is often an underlying lymphocytic thyroiditis process noted. Unfavorable prognosis is related to extracapsular extension, blood vessel wall infiltration, diffuse architectural pattern, and cervical lymph node involvement. We present two unusual cases of thyroid lymphoma presenting with acute airway obstruction and review the literature concerning this subject. One case presented a clinical and radiographic appearance similar to a prevertebral space abscess.

Abstract
An 80-yr-old female with a grade I diffuse goiter was diagnosed on fine-needle aspiration cytology as having Hashimoto's thyroiditis. Two years later, she developed a hard nodular growth in the right lobe of the thyroid, which was subjected to fine-needle aspiration and diagnosed as a non-Hodgkin's lymphoma. Immunocytology demonstrated the monoclonal B cell nature of the lesion. The patient underwent total thyroidectomy and is alive and free of the disease 27 mo after surgery.

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
Of 2,012 fine-needle aspirations (FNAs) of the thyroid performed between the years 1984 and 1988, detailed cytomorphologic analysis of 95 cases diagnosed as neoplastic on histology and/or cytology and those that received an equivocal cytodiagnosis are presented in this article. Discussed are medullary thyroid carcinomas (nine cases), clinically anaplastic thyroid tumors (CATT; eight cases), two cases of non-Hodgkin's lymphoma (NHL), and one primary leiomyosarcoma of the thyroid, for a total of 20 cases. Included in the category of CATT are all the thyroid tumors presenting clinically with an anaplastic growth pattern. The cytomorphology of these tumors varied, but the giant- and spindle-cell pattern was predominant. An accurate cytodiagnosis was possible, as per cytohistologic correlation, in seven cases, while in one case histological material was not available for study. Medullary carcinoma of the thyroid (MCT) showed a mixed spindle-cell and round-cell population in eight cases and an entirely spindle-cell population in one case. All cases of MCT were correctly diagnosed on cytology, and amyloid could be demonstrated in the cytologic smears in three cases. The cases of NHL and leiomyosarcoma could also be correctly interpreted on cytology.

Abstract
We have reviewed the local experience of 15 cases of thyroid lymphoma with a view to documenting the epidemiology, presentation, management and prognostic factors governing outcome for this rare condition. All the patients were European despite the fact that 15 per cent of the local population is either Maori or Polynesian. The average age at presentation was 62 years and 13 of the 15 patients were women. The duration of symptoms was short: on average 9 months. Where feasible a definitive resection of the lesion was performed but this could only be performed in six of the 15 cases. The commonest histological type was non-Hodgkin's lymphoma which accounted for 14 of the 15 cases with the large cell variant being the most common (five cases). The mean period of follow-up was 3.3 years: only eight patients were alive and well at that time. The prognostic factors that influenced outcome were: (1) the histology of the lesion - large cell lymphoma carried a bad outlook; (2) whether the lesion could be totally resected or not - five out of six patients undergoing total resection remain alive and well; (3) the presence of pre-existing Hashimoto's thyroiditis was a favourable prognostic factor as only one patient without underlying Hashimoto's disease or positive antithyroid antibodies was alive at the end of the study; (4) male sex may also be an unfavourable prognostic factor as both men in the study died of disease 0.3 and 5 years after diagnosis.

Abstract
This study analyzes the results of 46 cases of biopsy-proven primary lymphoma of the thyroid, localized at diagnosis and treated at the Royal Marsden Hospital between 1948-1980. In all cases, disease was limited to the thyroid and cervical lymph nodes. There were 43 females and 3 males, with a mean age of 64.4 years (median 66 years; range 17-86). A short history (less than 3 months) of a neck mass and local compressive symptoms was the typical presentation. The majority of patients (91%) had adverse histologies, with diffuse histiocytic lymphomas being most common (78%). The overall crude 5-year survival rate was 40%, with 30% of patients surviving beyond 10 years. Disease-free and overall survival were virtually identical, indicating the ineffectiveness of salvage therapy. The important prognostic factors were: size of tumor, fixation, extra-capsular extension, and retrosternal involvement. Survival was not correlated with age, sex, histology, thyroid status, or stage of disease, as defined by the Ann Arbor classification. Patients who had total macroscopic removal of tumor had the highest rate of local control and long survival (p less than 0.005). No significant difference was seen between lobectomy, subtotal or total thyroidectomy, but 7 of 9 long-term survivors (58-129 months) have had total thyroidectomy. A radiotherapy dose to the tumor, of at least 40 Gy, was required to produce consistent local control in patients with unresected disease. The majority of patients who died had generalized disease. Only 52% of these patients were free of local recurrence. In view of the frequency of occult disseminated disease, adjuvant chemotherapy is one recommendation for patients with poor prognostic factors. For optimal local control, complete surgical eradication is recommended followed by high-dose local radiotherapy. The use of aggressive cytoreductive chemotherapy prior to radiotherapy is a possible alternative option which needs to be explored.

Abstract
The purpose of this study was to evaluate the radiotherapeutic management of 38 patients, with malignant lymphoma of the thyroid, seen at the Mayo Clinic between 1965 and 1979. There were 8 males and 30 females with ages ranging from 34 to 90 years (mean age of 65 years). A tissue diagnosis was made in all patients and tissue was available for reclassification under the "Working Formulation" in 31 of the 38 patients. Twenty-six patients had intermediate grade histology, four low grade and one indeterminate. Twenty patients were clinical Stage IE, 14 patients Stage IIE, one patient Stage IIIE, one patient Stage IV and two patients were unstaged. All patients were treated with approximately 4000 rad megavoltage irradiation (range 2400-6000 rad) to the neck only (10 patients) or neck and mediastinum (28 patients). Twenty patients received subdiaphragmatic radiotherapy and four patients received adjuvant chemotherapy. Median follow-up was 56 months with minimum follow-up of 30 months. Overall disease-free survival at five years was 59%. Of 14 patients who experienced a recurrence, 10 (71%) failed in two or more sites. The most common site of failure was in para-aortic lymph nodes. One year survival following recurrence was 29%; however, four of six patients receiving salvage therapy survived at least two years. Patients receiving radiation treatment to the neck and mediastinum and those with no gross residual disease at the initiation of radiotherapy were less likely to develop a recurrence. Patients receiving a planned break during the course of therapy did not have reduced overall disease-free survival. However, 4 of 20 patients (20%) who received split course therapy failed within the radiation fields compared to 2 of 18 patients (11%) who had no treatment break. Only 1 of 4 patients (25%) receiving adjuvant chemotherapy survived one year. Side effects of radiotherapy were minimal. We believe the radiotherapeutic management of clinical Stage IE and IIE primary thyroid lymphoma should include treatment of the neck, axillae and mediastinum to a dose of approximately 4000 rad using a continuous course technique. Additionally, gross total removal of the disease surgically may be beneficial.
