Other than the influence of ionizing radiation and benign thyroid disease, little is known about the risk factors for differentiated thyroid cancer (TC) which is an increasing common cancer worldwide. Consistent evidence shows that body mass is positively associated with TC risk. As excess weight is a state of chronic inflammation, we investigated the relationship between concentrations of leptin, adiponectin, C-reactive protein, interleukin (IL)-6, IL-10 and tumor necrosis factor (TNF)-α and the risk of TC. A case-control study was nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) study and included 475 first primary incident TC cases (399 women and 76 men) and 1,016 matched cancer-free cohort participants. Biomarkers were measured in serum samples using validated and highly sensitive commercially available immunoassays. Odds ratios (ORs) of TC by levels of each biomarker were estimated using conditional logistic regression models, adjusting for BMI and alcohol consumption. Adiponectin was inversely associated with TC risk among women (ORT3vs.T1 = 0.69, 95% CI: 0.49-0.98, Ptrend = 0.04) but not among men (ORT3vs.T1 = 1.36, 95% CI: 0.67-2.76, Ptrend = 0.37). Increasing levels of IL-10 were positively associated with TC risk in both genders and significantly so in women (ORT3vs.T1 = 1.59, 95% CI: 1.13-2.25, Ptrend = 0.01) but not in men (ORT3vs.T1 = 1.78, 95% CI: 0.80-3.98, Ptrend = 0.17). Leptin, CRP, IL-6 and TNF-α were not associated with TC risk in either gender. These results indicate a positive association of TC risk with IL-10 and a negative association with adiponectin that is probably restricted to women. Inflammation may play a role in TC in combination with or independently of excess weight.

Fulltext Airway emergency from spontaneous haemorrhagic thyroid cancer

Vijendren A, Ladha N, Hilger AW

Med J Malaysia, 2014 Aug;69(4):187-8.

PMID: 25500848

Spontaneous thyroid haemorrhages are rare. There are reported cases occurring in thyroid nodules and cysts but none in thyroid malignancies. We describe a 48 year old who presented to the on-call ENT team with a rapidly progressing neck swelling that was interfering with his airway. After resuscitation, the patient underwent a right lobectomy to stop the bleeding. Histology showed a thyroid follicular carcinoma. As per the regional multidisciplinary team discussion, he underwent a completion thyroidectomy followed by radioactive iodine treatment. We conclude that spontaneous haemorrhages of the thyroid gland can occur in malignancies and stress the importance of early histological diagnosis.

Fulltext Extra-adrenal paraganglioma: presentation in three uncommon locations

Mun KS, Pailoor J, Chan KS, Pillay B

Malays J Pathol, 2009 Jun;31(1):57-61.

PMID: 19694315 MyJurnal

Extra-adrenal paragangliomata are uncommon entities. They can be classified into four basic groups according to their anatomical sites, i.e. branchiomeric, intravagal, aorticosympathetic and visceral autonomic. Similar tumours may arise in sites away from the usual distribution of the sympathetic and parasympathetic ganglia, e.g. orbit, nose, small intestine and even in the pancreas. We report three instructive cases of extra-adrenal paraganglioma which were found in unusual sites such as urinary bladder, thyroid gland and on the wall of the inferior vena cava.

PMID: 21610994 MyJurnal DOI: 10.2349/biij.5.4.e27

Medullary carcinoma is a rare breast carcinoma with a syncytial growth pattern and high-grade cytology. It can be difficult to diagnose and may be missed on conventional imaging as the findings may overlap with benign lesions i.e. fibroadenomas. The authors report a case of a 25-year-old female who presented with multifocal breast lumps diagnosed with medullary carcinoma and fibroadenomas. Imaging and pathological correlation with contrast-enhanced MRI are presented in the diagnosis of these lesions.

PMID: 14556337

Since January 1999, ten patients had undergone surgical treatment for metastatic bony lesions of proximal femur at this centre. Seven of these patients were treated for complete pathological fractures, one for impending fracture and one for revision of internal fixation and loosening of hemiarthroplasty. Primary malignancies were located in breast in four cases, prostate in three and one in lung, thyroid and neurofibrosarcoma. Two patients had died within six months after surgery, four after 1 year while the remaining four were still alive. The mean duration of survival was eleven months. Nine patients had been ambulating pain free and there were no failure of reconstruction.

Fulltext Concurrent Double Primary Tumours: Papillary Thyroid Carcinoma and Cervical Epithelioid Angiosarcoma

Lum SG, Mahmud N, Isa N, Mat Baki M

Medeni Med J, 2020;35(4):349-355.

PMID: 33717629 DOI: 10.5222/MMJ.2020.83479

Angiosarcoma is one of the rarest types of malignant vascular tumours that involved the head and neck region. It predominantly affects the scalp and superficial soft tissues. Angiosarcoma arising from the deep cervical soft tissue is extremely rare. There is a limited literature on neck angiosarcoma that occurred simultaneously with papillary thyroid carcinoma. We report a rare case of concurrent papillary thyroid carcinoma and cervical epithelioid angiosarcoma, and postoperative rapid progression of residual angiosarcoma that mimicked a neck haematoma. The diagnostic challenge and possible etiologies have been discussed here.

Fulltext The minimum amount of fluids needed to achieve the fastest time to reach permissible level for release in well-differentiated thyroid patients undergoing high-dose I-131 therapy

Cheen Hoe AK, Fong LY, Halim FNA, Fatt QK, Hamzah F

World J Nucl Med, 2018 7 24;17(3):182-187.

PMID: 30034283 DOI: 10.4103/wjnm.WJNM_59_17

Radioiodine (131I) therapy is the mainstay of treatment for patients who had undergone total thyroidectomy for well differentiated thyroid carcinoma. Increased fluid intake has always been encouraged to minimize the risk of non-target organ exposure to I-131radiation. This study aimed to determine the minimum amount of fluids needed for patients to have the fastest time to achieve permissible level for release after high dose I-131therapy.

METHODOLOGY: All the patients who were treated with high dose I-131from 18th January 2016 till 31st December 2016 in Hospital Pulau Pinang, Malaysia were recruited. The data from 126 patients on thyroxine hormone withdrawal (THW) group and 18 patients on recombinant human thyroid stimulating hormone (rhTSH) group were analysed. There is no change in patient management in terms of preparation, dose or post therapy whole-body scan. Fluid intake of patients were monitored strictly and whole-body retention of I-131are measured using ionizing chamber meter immediately after ingestion of I-131then at 1 hour, 24 hours, 48 hours, 72 hours and 96 hours.

RESULTS: The median time to achieve permissible release limit (50 μSV/hr at 1 meter) was 21.6 hours and 22.1 hours post-ingestion of I-131in the THW and rhTSH group respectively. The minimum amount of fluid needed to reach permissible release limit in the fastest time was 2,103 ml and 2,148ml for the THW and TSH respectively.

CONCLUSION: Clinicians would be able to evidently advise their patient on the amount of fluid to consume and utilize their isolation wards faster to treat more patients.

Primary thyroid lymphoma is a relatively uncommon pathology of the thyroid gland that mainly occurs in elderly females. We describe a rare case of B-cell thyroid lymphoma in a young healthy male. It is an important diagnosis to be considered in patients presenting with a rapidly enlarging neck mass as its management is different from other differentiated thyroid carcinoma which require total thyroidectomy plus adjuvant radioactive iodine ablation. Our report emphasizes the need for clinical awareness leading to early detection, followed by early multidisciplinary management.

MyJurnal

Primary thyroid lymphoma is a rare disorder accounting for about 2% of all malignant lymphomas and less than 5% of thyroid malignancies. It is an aggressive disease with poor outcome. The majority of thyroid lymphomas are non-Hodgkin lymphomas of Bcell origin. Majority of cases occur in women in the sixth decade. We report two cases of primary thyroid lymphoma and highlight the clinical issues and challenges posed by this rare disease. Both cases presented with respiratory obstructive symptoms that required surgical intervention. The optimal management for a primary thyroid lymphoma be it chemotherapy, radiotherapy, surgery or monoclonal antibodies is still debatable. The role for surgery has evolved through the years but its importance in emergency situations should not be overlooked. Both our patients had to undergo surgery but only one patient received additional chemotherapy and radiotherapy. These two case reports illustrated the difficulties in managing this rare disorder.

Thyroglossal duct cyst is the most common upper neck midline lesion in children. Approximately 1% of
thyroglossal duct cyst undergoes malignant transformation. Calcification which is a marker of malignancy
almost always points out to papillary thyroid carcinoma. Benign case of calcified thyroglossal cyst maybe
undiagnosed or under reported. We report a case of a 5 year old girl with a benign calcified thyroglossal
duct cyst, a fourth case in world literature. Here the differences between a benign and malignant
thyroglossal duct cyst are discussed.

Sternal metastasis from differentiated thyroid carcinoma (DTC) is rare and presents a conundrum for surgeons. We present a lady diagnosed with follicular thyroid carcinoma and sternal metastasis who underwent thyroidectomy, sternectomy and sternoplasty with titanium mesh and acrylic plate. She developed a surgical site infection, of which multiple conservative approaches were attempted. She eventually required removal of the implant. Closure of sternal defect was completed with bilateral pectoralis major advancement flaps. This article highlights a series of complications faced during the course of treatment and how they were managed in a tertiary healthcare centre.

Papillary thyroid cancer (PTC) is the most prevalent form of malignancy among all cancers of the thyroid. It is also one of the few cancers with a rapidly increasing incidence. PTC is usually contained within the thyroid gland and generally biologically indolent. Prognosis of the cancer is excellent, with less than 2% mortality at 5 years. However, more than 25% of patients with PTC developed a recurrence during a long term follow-up. The present article provides an updated condensed overview of PTC, which focuses mainly on the molecular alterations involved and recent biomarker investigations.

We report a unique case of differentiated thyroid carcinoma (DTC) with squamous metaplasia complicated with chronic discharging ulcer. A 76-year-old gentleman was referred to us after defaulted treatment 1 year post-total thyroidectomy. He presented to us with long-standing chronic, non-healing, ulcerative and discharging wound at the anterior neck at previous total thyroidectomy scar. The primary tumour was histologically diagnosed as papillary malignant cells with extensive squamous metaplasia. Squamous metaplasia is a rare finding in thyroid carcinoma that carried a poorer prognostic factor.

Farihah AG, Nurismah MI, Husyairi H, Shahrun Niza AS, Radhika S

Med J Malaysia, 2018 02;73(1):9-15.

PMID: 29531197 MyJurnal

AIM: This study aims to evaluate the reliability of the Ultrasound (U) Classification system in predicting thyroid malignancy by using pathology diagnosis as the reference standard.

METHODS: It was a cross-sectional study carried out at Universiti Kebangsaan Malaysia Medical Centre (UKMMC), Malaysia. Records of patients with focal thyroid nodules on ultrasound (US) for which US-guided fine needle aspiration cytology (FNAC) was performed and pathology results were available, from January 2014 to May 2016 were selected for review. Correlation of the U Classification with pathology results was assessed. Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, predictive value, negative predictive value and accuracy were calculated in a conservative and non-conservative method. The threshold for statistical performance was set at 0.05. Each sonographic feature was also compared with its pathology results.

RESULTS: A total of 91 patients with 104 nodules were eligible. 12 nodules out of 104 (11.5%) were malignant. The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, positive predictive value, negative predictive value and accuracy were 100%, 91.3%, 11.5, 0.0, 60%, 100% and 92.3%, and 100%, 91.4%, 11.7%, 0.0, 78.6%, 100% and 93.5%, for the non-conservative and conservative method of calculations respectively.

CONCLUSION: The U Classification is reliable in predicting thyroid malignancy. More evidence is nevertheless necessary for widespread adaptation and use.

Fulltext Metastatic Follicular Thyroid Carcinoma as a Cause of Low Serum Thyroxine with a Normal Thyroid Stimulating Hormone Level

Loh LT, Lim V

J ASEAN Fed Endocr Soc, 2017;32(1):57-59.

PMID: 33442087 DOI: 10.15605/jafes.032.01.11

Thyroid function is usually normal in differentiated thyroid carcinoma. We describe a case of a female patient who had metastatic follicular thyroid carcinoma (FTC) to the spine and lungs, who was clinically euthyroid but had very low free tetraiodothyronine (fT4) and normal thyroid stimulating hormone (TSH). Free triiodothyronine (fT3) and total T3 (TT3) were normal. Levothyroxine treatment increased fT4 marginally but caused a two- to three-fold rise in fT3 and TT3 along with suppressed TSH. This is likely due to hyperconversion of T4 to T3 from elevation in D2 deiodinase activity in the tumor. This phenomenon has been reported to occur in about 20% of metastatic FTC.

PMID: 23365506 MyJurnal

From 1996 to 2001, 393 thyroidectomies were performed and 25 (6.4%) patients underwent reoperative thyroid surgery at Hospital Universiti Sains Malaysia. All reoperated patients had undergone one prior thyroid operation. All were females with an average age of 39.1 years (18-61 years). The most frequent indication for reoperation was cancer in resected specimen of an originally misdiagnosed carcinoma treated by partial thyroid resection. Final histological diagnosis of 25 reoperations showed thyroid carcinoma in 22 (88%) cases and multinodular goiter in 3 cases. The overall interval between the initial and the reoperative procedures ranged from 3 weeks to 15 years. There was no post-operative mortality after reoperation. Post-operative complications were discovered in 5 patients, as 3 (12%) of whom had transient hypocalcaemia, one (4%) had wound breakdown and one (4%) had permanent recurrent laryngeal nerve palsy. Reoperative thyroid surgery is an uncommon operation with high complication rate.

Dural metastasis mimicking meningioma: an interesting case

Hamid HA, Gee KY, Muhammad R, Abd Rahman ZA, Das S

Acta Medica (Hradec Kralove), 2009;52(1):19-22.

PMID: 19754003

Dural metastasis is a rare entity in clinical practice. We report a case of dural metastasis secondary to thyroid carcinoma, which on both preoperative CT and MRI and at surgery had the typical appearance of a meningioma. Histopathological findings confirmed metastatic follicular thyroid carcinoma as a primary site. Although rare, dural metastases can mimic a meningioma. Our experience in this case has led us to consider metastasis as a differential diagnosis even when a meningioma is suspected. We believe that reporting of the case of dural metastasis mimicking a meningioma may help clinicians in future.

Fluorescence in situ hybridization analysis using PAX8- and PPARG-specific probes reveals the presence of PAX8-PPARG translocation and 3p25 aneusomy in follicular thyroid neoplasms

Chia WK, Sharifah NA, Reena RM, Zubaidah Z, Clarence-Ko CH, Rohaizak M, et al.

At the present time, the differentiation between follicular thyroid carcinoma (FTC) and adenoma can be made only postoperatively and is based on the presence of capsular or vascular invasion. The ability to differentiate preoperatively between the malignant and benign forms of follicular thyroid tumors assumes greater importance in any clinical setting. The PAX8-PPARG translocation has been reported to occur in the majority of FTC. In this study, a group of 60 follicular thyroid neoplasms [18 FTC, 1 Hurthle cell carcinoma (HCC), 24 follicular thyroid adenomas (FTA), 5 Hurthle cell adenomas (HCA), and 12 follicular variants of papillary thyroid carcinomas (FV-PTC)] were analyzed to determine the prevalence of the PAX8-PPARG translocation by fluorescence in situ hybridization. The PAX8-PPARG translocation was detected in 2/18 FTC (11.1%). In addition, 2/18 (11.1%) FTC and 1/5 (20%) HCA showed 3p25 aneusomy only. The frequency of the translocation detected in the study was lower compared to the earlier studies conducted in Western countries. This might be attributed to the ethnic background and geographic location. Detection of either the PAX8-PPARG translocation or the 3p25 aneusomy in FTC indicates that these are independent genetic events. It is hereby concluded that 3p25 aneusomy or PAX8-PPARG translocation may play an important role in the molecular pathogenesis of follicular thyroid tumors.

PMID: 19423453 DOI: 10.1016/S1015-9584(09)60015-4

BACKGROUND: Acute life threatening presentations of thyroid disease are uncommon. The aim of this study was to review our experience of emergency thyroid surgery with regard to the incidence, management and outcome to this approach.
METHODS: Forty patients who underwent emergency thyroid surgery from December 1998 to December 2007 were prospectively accrued in this study. There were 30 female and 10 male patients. The mean age was 63.8 years (range, 33-83 years). All patients had total thyroidectomy, except one patient who only had a right hemithyroidectomy for a dominant right multinodular goiter. Eight of the patients had been intubated before referring to our centre.
RESULTS: The mean weight of specimen was 219 g (range, 32-800 g). A histopathology report confirmed 16 patients had multinodular goiters, eight patients had papillary thyroid carcinomas, seven patients had anaplastic cancers, four patients had follicular thyroid carcinomas, two patients had thyroid lymphoma, one patient had medullary carcinoma, one patient had sarcoma and one patient had thyroid abscess. A total of 28 patients were discharged well postoperatively.
CONCLUSION: Acute life threatening presentations of thyroid disease are uncommon. However, early recognition of these problems is crucial and may life saving. Emergency thyroidectomy is important to release the critically obstructed airways. Nonetheless it is associated with higher risk of surgery and complication rate then any elective thyroid surgery.
