Abstract
Mucoepidermoid carcinomas (MECs) represent the most common malignant neoplasms of the salivary glands, but they have also been described in other unusual sites. Primary MECs originating in the thyroid gland are exceedingly rare, accounting for less than 0.5% of thyroid tumors. Owing to their low to medium grade, they are usually associated with an indolent evolution and a good long-term prognosis, generally being managed surgically based on the extent of the disease. However, this does not always apply, as primary thyroid MECs may present as metastatic or locally advanced diseases. While several treatment options have been explored in such cases, no consensus currently exists on their optimal treatment plan, and they should be managed in a multidisciplinary fashion. We report the case of a 67-year-old patient with primary MEC of the thyroid, which behaved aggressively, with extensive pulmonary metastasis, ultimately leading to the rapid clinical deterioration and death of the patient.

Abstract
Mucoepidermoid carcinoma (MEC) and sclerosing MEC with eosinophilia (SMECE) are rare primary thyroid carcinomas. In this study, we aimed to present our multicenter series of MEC and SMECE and integrated our data with published literature to further investigate the clinicopathological characteristics and prognoses of these tumors. We found 2 MECs and 4 SMECEs in our multicenter archives. We performed fluorescence in situ hybridization (FISH) to determine the MAML2 gene rearrangement. We screened for mutations in BRAF, TERT promoter, and RAS mutations using Sanger sequencing and digital polymerase chain reaction. Histopathologically, MECs and SMECEs were composed of two main cell types including epidermoid and mucin-secreting cells, arranged in cords, nests, and tubules. SMECEs were characterized by a densely sclerotic stroma with abundant eosinophils. We did not detect any MAML2 fusion in any of our cases. Two MEC cases harbored concomitant BRAF p.V600E and TERT C228T mutations. RAS mutations were absent in all cases. Concurrent foci of another thyroid malignancy were more commonly seen in MECs (p < 0.001), whereas SMECEs were associated with chronic lymphocytic thyroiditis (p < 0.001). MECs and SMECEs had equivalent recurrence-free survival (RFS) but MECs conferred significantly dismal disease-specific survival (DSS) as compared to SMECEs (p = 0.007). In conclusion, MECs and SMECEs not only shared some similarities but also demonstrated differences in clinicopathological characteristics, prognoses, and molecular profiles. SMECEs had a superior DSS in comparison to MECs, suggesting that they are low-grade cancers. This could help clinicians better evaluate patient outcomes and decide appropriate treatment plans.

Abstract
Lymph node metastases in non-well differentiated thyroid cancer (non-WDTC) are common, both in the central compartment (levels VI and VII) and in the lateral neck (Levels II to V). Nodal metastases negatively affect prognosis and should be treated to maximize locoregional control while minimizing morbidity. In non-WDTC, the rate of nodal involvement is variable and depends on the histology of the tumor. For medullary thyroid carcinomas, poorly differentiated thyroid carcinomas, and anaplastic thyroid carcinomas, the high frequency of lymph node metastases makes central compartment dissection generally necessary. In mucoepidermoid carcinomas, malignant peripheral nerve sheath tumors, sarcomas, and malignant thyroid teratomas or thyroblastomas, central compartment dissection is less often necessary, as clinical lymphnode involvement is less common. We aim to summarize the medical literature and the opinions of several experts from different parts of the world on the current philosophy for managing the neck in less common types of thyroid cancer.

Abstract
Thyroid mucoepidermoid carcinoma (MEC) is a rare thyroid malignancy first documented in 1977. The majority of thyroid MECs are indolent, low-grade tumours with excellent prognosis. A woman in her 60s presented with an ongoing sensation of a lump in the left neck. There were no swallowing, voice or airway concerns. Ultrasound of the neck showed an enlarged thyroid with U5 and U3 features on the right and left lobes, respectively. Right fine needle aspiration cytology (FNAC) demonstrated certain features of Hurthle cell or anaplastic carcinoma (Thy5). Left FNAC showed Hurthle cell changes with atypical cells and prominent nucleoli (Thy3a). Following total thyroidectomy, histopathology revealed synchronous right low-grade MEC and left papillary thyroid microcarcinomas (pT2(m) N0 M0) on a background of Hashimoto's thyroiditis. This case adds to the literature and details the key histopathological features for a rare but important differential in patients with thyroid carcinoma due to synchronous histological types.

Abstract
Mucoepidermoid carcinoma (MEC) is the most common malignant neoplasm of the salivary gland, but primary thyroid MEC has rarely been reported and usually has a good prognosis. Herein, I report a case of thyroidal MEC with a poor prognosis in an 82-year-old woman with an anterior neck mass. Ultrasonography and computed tomography revealed a thyroid mass. The patient initially underwent fine-needle aspiration, was diagnosed with malignancy, and underwent a right lobectomy. On gross examination, a 4.0×3.6×2.6 cm-sized ill-defined, unencapsulated, and infiltrative tan to whitish mass with necrosis was identified. Microscopically, epidermoid tumor cell nests or solid sheets were identified. Mucous cells that were positive for periodic acid-Schiff and mucicarmine stains were also identified within epidermoid cell nests. Frequent mitosis and necrosis were observed. Immunohistochemical staining for p40 and p63 was positive, and that for thyroid transcription factor-1 and paired box gene 8 was focally positive. According to the Armed Forces Institute of Pathology grading system for salivary gland MEC, the current case was classified as high-grade MEC. After surgery, the patient suffered from dyspnea due to a remnant neck mass that compressed and obstructed the trachea; therefore, the patient refused further treatment. Thyroidal MECs are considered low-grade with a favorable prognosis, but there are several reported cases of thyroidal MEC with poor prognosis. The current case is a rare presentation of high-grade thyroidal MEC with a poor prognosis.

Abstract
Mucoepidermoid carcinomas (MECs) are the most common malignant tumour of the salivary glands. MECs have also been reported to occur in atypical sites. Primary MECs of the thyroid gland are extremely rare, accounting for 0.5% of thyroid malignancies with approximately 48 cases reported in the literature. In most cases, these are low-grade neoplasms with good long-term prognosis. We present the case of a 74-year-old patient with poorly differentiated MEC of the thyroid gland, which behaved aggressively resulting in rapid decline and death of the patient. The exact pathophysiology of the disease remains unclear and there is no consensus on the optimal treatment for this histological subtype. Recognition and diagnosis of this rare neoplasm are important as this can help guide optimal treatment, although in high-grade poorly differentiated cases, treatment options remain limited.

Abstract
Thyroid carcinomas represent 3.2% of all new cases of cancer in the United States. Whereas most thyroid tumors arise from follicular cells or, less commonly, parafollicular cells, the derivation of some rare primary thyroid carcinoma subtypes is less clear and represents an area of evolving knowledge. Primary thyroid carcinomas that resemble neoplasms characteristic of the salivary glands ("salivary-like" primary thyroid carcinomas) arguably represent some of the most unusual primary thyroid tumors. Herein, we have undertaken a review of the literature in order to present a comprehensive overview of salivary-like primary thyroid carcinomas including: mucoepidermoid carcinoma, sclerosing mucoepidermoid carcinoma with eosinophilia, and secretory carcinoma. Awareness of these unusual, distinct primary tumors is important for timely diagnosis and optimal patient management. This review highlights these three salivary-like carcinomas, with special emphasis on developments since publication of the World Health Organization (WHO) 2017 Classification of Tumours of Endocrine Organs.

Abstract
Mucoepidermoid variant of thyroid carcinoma is a rare and complex disease. Securing a diagnosis and formulating an evidence-based treatment plan is challenging. A case report of a patient with the dual pathology of a composite mucoepidermoid carcinoma of the thyroid and a follicular variant of papillary thyroid carcinoma with malignant metastasis is presented in this article. We discuss the challenges in diagnosis, prognostic factors and management of this rare presentation by reviewing current literature.

Abstract
Mucoepidermoid carcinomas (MECs) are generally found in salivary gland, but they have also been mentioned in other organs such as the larynx, esophagus, breast. MECs are considered to be a low-grade carcinoma and their occurrence in the thyroid is extremely rare. We present a 54-year-old male patient admitted to our clinic, complaining about having back pains for approximately three months. A lumbosacral spine MRI and a PET/CT scan revealed multiple lesions in the L4, L5, S1 vertebra bodies, sacral bone and left pelvis bone, suggesting of a metastatic disease. The result of thyroid FNA was carcinoma and a biopsy of the vertebra bone confirmed the presence of a metastatic carcinoma. A total thyroidectomy and level VI neck dissection was conducted followed by palliative external beam radiotherapy (30 Gy) to the vertebra bodies, sacral bone and left pelvis bone. In pathological studies, the diagnosis of thyroid mucoepidermoid carcinoma was confirmed. Six months after treatment, the patient died due to severe pain and fatigue caused by the disease. Here, we report a rare case with bone metastasis as the first symptom of MEC and a brief review of published literature on the subject.

Abstract
We report three cases of thyroid sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE), which is an extremely rare variant of mucoepidermoid carcinoma (MEC). The aims of this report were to describe the clinicopathological findings, including results from immunohistochemical and fluorescence in situ hybridization analysis of thyroid SMECE, as well as to discuss the distinction between thyroid SMECE and its salivary counterpart. The cases included a 63-year-old female, a 44-year-old male, and a 66-year-old female, with all patients presenting with Hashimoto's thyroiditis. Nodal metastasis was not found in any of the three cases. Neither regional recurrences nor distant metastases were found in any patient during the follow-up, which was 20 years, 3 years, and 18 months, respectively. Histologically, tumors were composed of epidermoid carcinoma cells, intermediate type carcinoma cells, and goblet cell-type mucus-secreting carcinoma cells, with all tumors displaying a sclerotic stroma with eosinophilic and lymphocytic infiltration. The formation of eosinophilic abscess in the tumor nests that might be a novel characteristic finding of SMECE was observed. Immunohistochemically, the carcinoma cells were positive for cytokeratin 34βE12, TTF-1, and PAX8, but negative for thyroglobulin. In two cases, increased IgG4-positive plasma cells were observed. Mastermind-like transcriptional coactivator 2 (MAML2), according to fluorescence in situ hybridization, was intact in all cases. In conclusion, thyroid SMECE has favorable outcomes and seems to be genetically different from salivary MEC. This is the first report to describe the presence of increased IgG4-positive plasma cells in the stroma of SMECE.

Abstract
Primary mucoepidermoid carcinoma (MEC) of the thyroid and columnar cell variant of papillary carcinoma of the thyroid (PCT) are uncommon neoplasms. We report the first case of composite MEC and columnar cell variant of PCT. An 86-year-old man consulted for a 47-mm thyroid nodule, cytologically compatible with PCT. Total thyroidectomy was performed. Histological diagnosis, with support of histochemistry and immunohistochemistry, was mixed primary carcinoma of the thyroid, associating an MEC component with predominantly columnar cell variant of PCT. Sixteen months after surgery and external beam radiation therapy, the patient was free of recurrence or distant metastasis. This case report offers an opportunity to highlight the potential pitfalls concerning the interpretation of mucin histochemistry in thyroid tumors.

Abstract
Fine-needle cytology (FNC) is frequently used to diagnose thyroid nodules discovered by palpation or imaging studies. Molecular tests on FNC material may increase its diagnostic accuracy. We report a case of a classic papillary thyroid carcinoma combined with a mucoepidermoid carcinoma correctly identified on FNC. The papillary component had a classic immunophenotype (CK19+, TTF1+), while the mucoepidermoid one was only focally CK19+. Point mutations (BRAF and RAS) and rearrangements (RET/PTC) of the papillary component have been also investigated on FNC samples, with resulting concurrent rearrangements of RET/PTC1 and RET/PTC3, but no point mutations. The histogenesis of combined papillary and mucoepidermoid carcinoma of the thyroid still remains partly unsettled, and further genomic studies are needed to shed some more light on this peculiar neoplasm.

Abstract
Thyroglossal duct remnants should be surgically excised, if possible due to the risk of malignant transformation. Mucoepidermoid carcinomas can present in diverse locations outside of salivary glands. A high index of suspicion for malignancy is required with neck masses in adults, especially following a period of rapid growth. If aggressively treated, patients with mucoepidermoid carcinoma outside of salivary glands may still have a favourable prognosis.
Introduction Thyroglossal duct cysts (TDC) are common midline neck swellings resulting from embryological remnants of the thyroglossal duct. They often contain ectopic thyroid tissue and malignant transformation has been reported, most commonly to papillary thyroid carcinoma. Mucoepidermoid carcinoma (MEC) usually occurs in the salivary glands and only rarely in the thyroid. This is the first case of a MEC occurring within a thyroglossal duct remnant. Presentation of a case A 73 year old lady presented with a thyroglossal duct cyst. She declined surgical excision, as she was adamant she wanted to avoid surgery. The neck mass rapidly enlarged at two years following initial diagnosis. Fine needle aspiration cytology was suspicious for carcinoma. She underwent total thyroidectomy and selective central compartment neck dissection with adjuvant radiotherapy. She remains alive and well two years post treatment. Discussion Mucoepidermoid carcinoma is the most common malignant neoplasm of salivary glands, although it has rarely been reported in diverse locations including the thyroid, lung and pancreas. To the best of our knowledge, this is the first reported case of mucoepidermoid carcinoma arising from a thyroglossal duct remnant. Conclusion This case adds weight to the literature favouring surgical excision of thyroglossal duct remnants due to the risk of malignant transformation.

Abstract
Mucoepidermoid carcinoma is the most common salivary gland malignancy and it may arise anywhere that salivary tissue is present. Mucoepidermoid carcinoma has been reported to arise de novo within the thyroid gland, and here, we describe three cases of primary mucoepidermoid carcinoma of the thyroid, including clinical presentation, diagnostic evaluation, and clinical follow-up, along with a discussion of tumor origin and a review of the literature.
