Primary squamous cell carcinoma of the thyroid--a case report

Wan Muhaizan WM, Phang KS, Sharifah NA, al Amin D

Malays J Pathol, 1998 Dec;20(2):109-11.
PMID: 10879272

A rare case of primary squamous cell carcinoma of the thyroid is reported herein. A 64-year-old Malay lady presented with a gradually enlarging thyroid nodule for the past 6 months and underwent total thyroidectomy. Histopathology revealed a squamous cell carcinoma of the thyroid with complete resection. Possible primary tumour elsewhere was excluded. Postoperative irradiation was given and patient is still alive after 2 years of follow-up.

Cytology of columnar-cell variant of papillary thyroid carcinoma

Jayaram G

Diagn Cytopathol, 2000 Apr;22(4):227-9.
PMID: 10787142

Columnar cell variant of papillary carcinoma (CCV-PC) thyroid is a rare and aggressive tumor composed of tall columnar cells that form papillae, glands and solid structures. This paper describes fine needle aspiration (FNA) cytologic features in a case of CCV-PC occurring in the right thyroid lobe of a 27-year-old female. Smears showed tall columnar cells in monolayered, three-dimensional, acinar and occasional papillary clusters. Nuclei were oval or elongated and monomorphic. Nuclear pseudostratification, resembling that seen in respiratory epithelial cells, was present in some of the cell clusters. Occasional cells showed squamous or Hurthle cell metaplasia. Nuclear grooves and intranuclear cytoplasmic inclusions were not seen. Sections of the right lobectomy specimen showed an well-encapsulated CCV-PC with capsular and vascular permeation. Tall cell variant of papillary carcinoma (TCV-PC) can be distinguished from CCV-PC by the oxyphilia of the tumor cells and the absence of nuclear pseudostratification. Colorectal and endometrial adenocarcinomas metastatic to the thyroid may be difficult to distinguish from CCV-PC.

Fulltext Emergency thyroid surgery: a surgical challenge

Rohana A, Hisham AN

Asian J Surg, 2009 Apr;32(2):81-4.

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.

Follicular thyroid carcinoma with direct tumour extension into the great cervical veins and right atrium: is transcervical thrombectomy a safe option?

Taib NA, Hisham AN

Asian J Surg, 2007 Jul;30(3):216-9.
PMID: 17638642

Direct tumour extension into the internal jugular veins (IJV) and right atrium in thyroid cancer is extremely uncommon. We report three cases of advanced thyroid cancer invading into the IJV and right atrium. All three patients had well-differentiated thyroid cancer and presented with typical clinical picture of the superior cava syndrome coupled with significant compressive symptoms. Two patients had obvious tumour thrombus extending to the superior vena cava (SVC) and right atrium, whilst in one patient, the thrombus extended to the SVC close to the edge of the right atrium. In all three patients, the intraluminal tumour thrombus was clinically palpable. Involvement of the IJV, SVC and right atrium was confirmed with computed tomography (CT) scan and echocardiography. The decision to extract the thrombus transcervically was made on the basis of the positive "ring sign", which is a thin rim of contrast surrounding the tumour thrombus documented on CT. All three patients underwent total thyroidectomy with segmental resection and ligation of the IJV. The tumour thrombus was successfully extracted transcervically. The histopathology report confirmed follicular carcinoma in all three patients. Two patients had radioiodine ablation therapy postoperatively, and were well 18 months after operation. One patient who had lung metastases documented on chest CT succumbed to the disease due to massive haemoptysis 3 weeks after operation.

Fulltext Large fungating thyroid cancers: a unique surgical challenge

Harjit KD, Hisham AN

Asian J Surg, 2005 Jan;28(1):48-51.
PMID: 15691799

Large goitres are common in the developing world, particularly in Asia and Africa. Nonetheless, large fungating goitres are extremely rare and represent a unique challenge to surgeons. Surgery should always be considered, when the general condition of the patient permits, to provide a better quality of life as it offers the only hope of long-term survival. The potential gain with surgery is that it allows maximum benefit for more effective radioactive iodine ablation and radiotherapy treatment. We report two cases of large fungating thyroid cancers complicated by anaemia and foul-smelling discharge.

Follicular adenoma with squamous metaplasia and cystic change: report of a case with fine needle aspiration cytological and histological features

Jayaram G, Jayalakshmi P

Malays J Pathol, 1999 Dec;21(2):101-4.
PMID: 11068414

Squamous metaplasia (SM) of thyroid follicular epithelium is known to occur in a variety of non-neoplastic lesions as well in thyroid neoplasms, notably papillary carcinoma (PC). In follicular thyroid tumors, on the other hand, SM is very rare. This case describes cytological and pathological findings in a follicular adenoma (FA) that presented as a cystic lesion with extensive SM. The fine needle aspiration (FNA) cytology sample in this case yielded only necrotic material from the cystic area and squamous cells, which being mostly of immature type, were not recognised as squamous in the cytological smears. The needle missed the solid (neoplastic) component of the lesion and on the whole the cytological picture was considered to be equivocal. FA can now be added to the spectrum of thyroid lesions that can show SM. Awareness of this will enable cytopathologists to consider non-papillary lesions in the differential diagnosis of thyroid nodules that yield squamous cells.

Fulltext Outcome of Cervical Lymph Nodes Dissection for Thyroid Cancer with Nodal Metastases: A Southeast Asian 3-Year Experience

Lim RZM, Ooi JY, Tan JH, Tan HCL, Sikin SM

Int J Surg Oncol, 2019;2019:6109643.
PMID: 30941211 DOI: 10.1155/2019/6109643

Introduction: Therapeutic nodal dissection is still the mainstay of treatment for patients with lymph node metastases in many centres. The local data, however, on the outcome of therapeutic LND remains limited. Hence, this study aims to inform practice by presenting the outcomes of LND for thyroid cancer patients and our experience in a tertiary referral centre.
Methods: This is a single-centre retrospective observational study in a Malaysian tertiary endocrine surgery referral centre. Patients who underwent total thyroidectomy with lymph node dissection between years 2013 and 2015 were included and electronic medical records over a 3-year follow-up period were reviewed. The outcomes of different lymph node dissection (LND), including central neck dissection, lateral neck dissection, or both, were compared.
Results: Of the 43 subjects included, 28 (65.1%) had Stage IV cancer. Among the 43 subjects included, 8 underwent central LND, and 15 had lateral LND while the remaining 20 had dissection of both lateral and central lymph nodes. Locoregional recurrence was found in 16 (37.2%) of our subjects included, with no statistical difference between the central (2/8), lateral (7/15), and both (7/20). Postoperative hypocalcaemia occurred in 7 (16.3%) patients, and vocal cord palsy occurred in 5 (11.6%), whereas 9 patients (20.9%) required reoperation. Death occurred in 4 of our patients.
Conclusion: High recurrence and reoperative rates were observed in our centre. While the routine prophylactic LND remains controversial, high risk patients may be considered for prophylactic LND. The long-term risk and benefit of prophylactic LND with individualised patient selection in the local setting deserve further studies.

A reappraisal of thyroid surgery under local anaesthesia: back to the future?

Hisham AN, Aina EN

ANZ J Surg, 2002 Apr;72(4):287-9.
PMID: 11982518 DOI: 10.1046/j.1445-2197.2002.02372.x

BACKGROUND: Thyroid surgery is usually performed under general anaesthesia. However, for a selected group of patients, local anaesthesia may be preferable. The aim of this study was to review the authors' experiences with local anaesthesia with regard to the safety and outcome of this approach.
METHODS: A total of 65 consecutive patients who underwent primary thyroid surgery were accrued prospectively into this study from May to December 1999. A field block with 0.5% bupivacaine and adrenaline in 1:200 000 dilutions was given in all cases. In addition, light sedative and narcotics were given as necessary to achieve patient comfort and cooperation. The pain experienced during surgery was recorded using a visual analogue scoring system on a scale of 1-10.
RESULTS: Unilateral thyroid resection was performed in 58 patients, isthmectomy in four patients and bilateral thyroid resection in three patients, two of which were in their second trimester of pregnancy diagnosed with papillary thyroid cancer. There were 55 women and 10 men with an average age of 38.2 years (range: 18-67 years). No conversion to general anaesthetic was needed, and the mean operating time was 80 min. The postoperative recovery was quick with this technique and, of interest, 22 (33.9%) patients were discharged within 6 h following the surgery. Overall 62 (95.4%) patients were discharged in the first 24 h and three (4.6%) patients after 24 h. There were no significant postoperative complications encountered except for wound infection in two (3.1%) patients.
CONCLUSIONS: Thyroid surgery under local anaesthesia can be performed safely in a selected group of patients. It offers an effective alternative approach to general anaesthesia and is associated with low morbidity and high levels of patient satisfaction.

Fulltext Carcinoma of thyroid--clinical presentation and outcome

Sothy K, Mafauzy M, Mohamad WB, Mustaffa BE

Med J Malaysia, 1991 Sep;46(3):212-7.
PMID: 1839914

The clinical, biochemical and pathological features of 31 patients with thyroid carcinoma managed at Hospital Universiti Sains Málaysia, Kubang Kerian from 1985 to 1989 were analyzed. There were 25 females and 6 males. The types of carcinoma were: papillary-17 cases; follicular-10 cases; medullary-2 cases and anaplastic-2 cases. For papillary carcinoma the mean age of the patients was 52.9 years. For follicular carcinoma the mean age was 48.3 years, for medullary carcinoma, 48.5 years and for anaplastic, 74.5 years. All patients had pre-existing goitre except for 2 and most presented with advanced disease. The mean duration of symptoms for papillary carcinoma was 3.7 years, follicular carcinoma 1.6 years, medullary carcinoma 13.5 years and anaplastic carcinoma 6 months. 12 patients presented with goitre of increasing size; 9 had compression symptoms; 4 presented with cervical lymph node enlargement and 6 presented with bony pains of whom 2 had paraplegia. None of the patients were ever thyrotoxic or hypothyroid. Treatment in general was unsatisfactory because of patients' non-acceptance of surgery and/or radioactive iodine.

Cunningham IG, Lee YK

Aust N Z J Surg, 1975 Aug;45(3):285-9.
PMID: 1058690

A group of patients with solitary nodules of the thyroid were treated at the University of Malaya by surgery under local anaesthesia. This was done in order to expedite exploration of a potentially malignant condition. This group comprised 43 patients, and four cancers were found. The standard technique used was satisfactory from the viewpoint of both the patient and the surgeon. The pattern of this condition in a Malaysian population is documented, the technique used is described, and thyroidectomy under local aneaesthesia is discussed.

Comparison of free hand versus ultrasound-guided fine needle aspiration of thyroid with histopathological correlation

Krishnappa P, Ramakrishnappa S, Kulkarni MH

J Environ Pathol Toxicol Oncol, 2013;32(2):149-55.
PMID: 24099428

Fine-needle aspiration (FNA) cytology of the thyroid is usually performed on an outpatient basis. The results of FNA are operator dependent and may be affected by the lesion characteristics and the aspiration technique. In current practice ultrasound (US) is widely used to guide the needle for aspiration of nondominant nodules. Our study aimed to compare the free-hand FNA with US-guided FNA in the evaluation of thyroid nodules. A total of 91 cases of thyroid lesions were studied at the Department of Pathology, Karnataka Institute of Medical Sciences, Hubli, India. All the cases underwent free-hand and US-guided FNA. The cytological samples from both procedures were analyzed for adequacy, cytological features, and possible diagnosis. The results were correlated with histopathological diagnosis whenever possible. Of 91 aspirates, 89 were satisfactory and 2 were unsatisfactory on US-guided FNA, whereas 85 were satisfactory and 6 were unsatisfactory in free-hand FNA. Of 91 cases 68 (74.7%) were nonneoplastic lesions and 21 (23.1%) were neoplastic lesions in US-guided FNA, whereas 67 cases (73.6%) were nonneoplastic and 18 cases (19.8%) were neoplastic in free-hand FNA. Histopathological study was possible in 25 patients, among whom 15 lesions were nonneoplastic and 10 were neoplastic. Sensitivity and specificity of US-guided FNA to detect neoplastic lesions were 81.81% and 92.85%, respectively, compared with free-hand FNA, for which the sensitivity and specificity were 54.54% and 92.85%, respectively. The diagnostic accuracy of guided FNA was 88% against the 76% accuracy rate of free-hand FNA. US-guided FNA provides a better representative sample and has a higher diagnostic rate in the evaluation of thyroid lesions.

Fulltext Triple primary cancers of the larynx, lung and thyroid presenting in one patient

Iqbal FR, Sani A, Gendeh BS, Aireen I

Med J Malaysia, 2008 Dec;63(5):417-8.
PMID: 19803306 MyJurnal

Patients with multiple malignant primary tumours are often described, based on their chronology of presentation, as simultaneous, synchronous or metachronous tumours. Lung malignancies presenting in association with head and neck tumours are well documented while there have been small series of thyroid synchronous cancers presenting with laryngeal lesions in literature. No cases, to our knowledge, have been reported in literature of a single patient with all three laryngeal, lung and thyroid malignancies. We report one such case of a 71-year-old Chinese man who had undergone a total laryngectomy for a recurrent cancer of the larynx only to be found to have tumours of the lung and thyroid in the post-operative period and he eventually died of post-operative complications. We also discuss screening for lung and thyroid malignancies in patients with head and neck squamous cell carcinoma (SCC).

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.

Fulltext Thyroid carcinoma in patients with familial adenomatous polyposis

Rohaizak M, Jasmi AY, Ismail MA, Munchar MJ, Meah FA

Asian J Surg, 2003 Jul;26(3):183-5.
PMID: 12925296 DOI: 10.1016/S1015-9584(09)60381-X

There has been a growing awareness of the association between papillary thyroid carcinoma and familial adenomatous polyposis (FAP). The cases of four young patients with papillary thyroid carcinoma occurring with FAP are presented. Three patients underwent surgery to provide specimens for detailed histological examination. The surgical specimens showed well-encapsulated multicentric tumours exhibiting a predominantly papillary architectural growth pattern. In some areas, follicular architecture and cribriform patterns were noted. Atypical areas of spindle cells in a trabecular or solid configuration, which are not normally seen in classical papillary thyroid carcinoma, were evident. Malignant cells exhibited a graduation of cuboidal to tall cells with abundant amphophilic cytoplasm. The nuclei did not exhibit the typical nuclear clearing as seen in papillary thyroid carcinoma, but nuclear grooving and inclusions were noted. Psammoma bodies were not seen in any of the specimens. In a limited review of these patients, features such as young age at presentation, multicentricity and unusual histology suggest that thyroid carcinoma associated with FAP may represent a distinct form of thyroid cancer.

Fulltext Metastatic disease of the proximal femur

Faisham WI, Zulmi W, Biswal BM

Med J Malaysia, 2003 Mar;58(1):120-4.
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.
