    Papillary thyroid carcinoma is a common thyroid malignancy reported world wide. It affects females more commonly in the 4th to 6th decades of life. The patients usually present with a painless anterior neck mass and occasionally with lymph node involvement. We report a case of an elderly male who presented with hoarseness and hemoptysis, which warranted bronchoscopy. Biopsy of the intraluminal tracheal mass revealed the diagnosis of papillary thyroid carcinoma. Computed tomography scan of the neck confirmed the presence of the primary lesion in the right thyroid lobe with invasion into the adjacent trachea and esophagus.

    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.

    OBJECTIVE: Early detection and precise diagnosis of breast cancer (BC) plays an essential part in enhancing the diagnosis and improving the breast cancer survival rate of patients from 30 to 50%. Through the advances of technology in healthcare, deep learning takes a significant role in handling and inspecting a great number of X-ray, MRI, CTR images.  The aim of this study is to propose a deep learning model (BCCNN) to detect and classify breast cancers into eight classes: benign adenosis (BA), benign fibroadenoma (BF), benign phyllodes tumor (BPT), benign tubular adenoma (BTA), malignant ductal carcinoma (MDC), malignant lobular carcinoma (MLC), malignant mucinous carcinoma (MMC), and malignant papillary carcinoma (MPC).

    METHODS: Breast cancer MRI images were classified into BA, BF, BPT, BTA, MDC, MLC, MMC, and MPC using a proposed Deep Learning model with additional 5 fine-tuned Deep learning models consisting of Xception, InceptionV3, VGG16, MobileNet and ResNet50 trained on ImageNet database. The dataset was collected from Kaggle depository for breast cancer detection and classification. That Dataset was boosted using GAN technique. The images in the dataset have 4 magnifications (40X, 100X, 200X, 400X, and Complete Dataset). Thus we evaluated the proposed Deep Learning model and 5 pre-trained models using each dataset individually. That means we carried out a total of 30 experiments. The measurement that was used in the evaluation of all models includes: F1-score, recall, precision, accuracy.

    RESULTS: The classification F1-score accuracies of Xception, InceptionV3, ResNet50, VGG16, MobileNet, and Proposed Model (BCCNN) were 97.54%, 95.33%, 98.14%, 97.67%, 93.98%, and 98.28%, respectively.

    CONCLUSION: Dataset Boosting, preprocessing and balancing played a good role in enhancing the detection and classification of breast cancer of the proposed model (BCCNN) and the fine-tuned pre-trained models' accuracies greatly. The best accuracies were attained when the 400X magnification of the MRI images due to their high images resolution.

    Breast masses occur in men far less commonly than women. Papillary lesions of the male breast are rare and comprise a spectrum of lesions ranging from benign intraductal papilloma to intraductal papillary carcinoma and invasive papillary carcinoma. In this case report, a 78-year-old man presented with a subareolar painless mass. Fine needle aspiration cytology (FNAC) was performed. Cytologic examination revealed a cellular aspirate. A diagnosis of papillary lesion favoring papillary carcinoma was rendered. The patient underwent modified radical mastectomy, which showed invasive papillary carcinoma. As far as we know, only a few cases of invasive papillary carcinoma of the male breast have been published in the literature. To the best of our knowledge, this is the first case report of invasive papillary carcinoma of male breast in Malaysia. In this purview, we discuss papillary carcinoma of male breast with review of the relevant literature.

    Solid papillary breast carcinoma is a rare type of breast carcinoma. We present four cases which highlight the radiological and histological findings of solid papillary carcinoma. Mammogram supplemented with ultrasound played an important role in detecting solid papillary carcinomas which usually presents as intraductal lesions or intracystic mass with Doppler signal. Excision biopsy is a better option than core biopsy as the latter modality may not be representative and the diagnosis of solid papillary breast carcinoma may be missed.

    Papillary thyroid carcinoma (PTC) associated with familial adenomatous polyposis (FAP) is rare. It is usually associated with the cribriform-morular variant of PTC, with unusual patterns on detailed histology examination. This variant is known to have a good prognosis. Papillary thyroid carcinoma associated with FAP commonly occurs in females in their 30s and rarely in the elderly. We report a case of a 69-year-old female presenting with thyroid swelling and a history of FAP.

    Solid-pseudopapillary tumour (SPT) is a rare exocrine tumour of the pancreas and is considered to have low malignant potential. Few morphological criteria are used to predict malignant behaviour such as equivocal perineural invasion, angioinvasion and invasion to surrounding tissue, and should be designated as solid-pseudopapillary carcinoma (SPC). We report a case of SPC. Clinical and radiological findings are typical for SPT with no metastatic disease. There is no tumour recurrence after 4 months postresection. Clinical history and radiological findings were retrieved from the patient's record sheet and Viarad system. H&E staining and few immunoproxidase staining were reviewed by several pathologists. The histological findings are typical for SPT, with additional perineural invasion. There is no angioinvasion or capsular invasion identified. This is our first experience in diagnosing and managing SPC. We look forward to seeing the patient's disease status during her next routine follow-up. We expect good disease-free survival and very low risk of tumour recurrence, in view of only one risk factor (perineural invasion) and uninvolved surgical margins by the tumour.

    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.

    Patient with thyroid mass rarely presents in emergency situation. It is because the nature of the mass is that it usually increases slowly in size. Thus, any surgical intervention can be planned electively. The most common condition that necessitates urgent intervention, is upper airway compromise due to sudden rapid increase in size of the swelling. This can be due to intralesional bleeding or superimposed infection on the enlarged gland. We report a case of urgent completion thyroidectomy performed to a patient with fungating recurrent papillary carcinoma who present with bleeding from the mass externally.

    Papillary thyroid microcarcinoma is not uncommon
    and constitutes almost one third of all differentiated
    thyroid carcinomas. It is generally regarded as low risk
    and usually an incidental finding from histopathology
    examination. Some areas of management of this entity
    remains uncertain and requires a multidisciplinary
    approach. We present a patient who initially came to
    us with symptoms of hyperthyroidism, later underwent
    thyroidectomy for a suspicious lesion but was found to
    have micropapillary thyroid carcinoma in another part
    of her thyroid gland.

    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.

    Solid pseudopapillary neoplasm (SPN) of the pancreas is considered a low-malignant neoplasm with a good prognosis. However, 5% to 15% of patients with SPNs develop metastatic disease, most commonly in the liver. Metastatic hepatic malignancies that show pseudocystic features are rare. Here we describe the case of a middle-aged female with a cystic liver metastasis from SPN. To the best of our knowledge, SPN with a single cystic liver metastasis has not been described, although these tumours frequently undergo haemorrhagic-cystic degeneration. Thus, in these patients the marked cystic change could be misinterpreted as a benign lesion.

    BACKGROUND: Fine needle aspiration cytology (FNAC) is a reliable and reproducible diagnostic technique for thyroid lesions with certain limitations. Computed morphometric methods have been introduced with a view to improve the diagnostic yield of thyroid aspirates. However, a review of the existing literature revealed conflicting reports regarding morphometric parameters in thyroid neoplasms.

    MATERIALS AND METHODS: This study included 50 cases of thyroid lesions (20 cases of colloid goitre, 15 of follicular adenoma, 5 of follicular carcinoma and 10 papillary carcinomas). Digital images of cytologic smears of these cases were captured using a dedicated photomicrography system and nuclear profiles traced manually. With self-designed image analysis software, nuclear morphometric measurements, including texture analysis, were performed. Discriminant analysis was performed including the morphometric parameters and percentage of correctly classified nuclei noted.

    RESULTS: Nuclear morphometry parameters showed that papillary thyroid carcinoma had the highest perimeter, area, radius and elongation factor compared to other thyroid lesions. Discriminant analysis revealed that altogether 77.9% of cells could be correctly classified to their lesion category based on the nuclear morphometric and textural parameters. Of the neoplastic cases, 84.5% of cells of follicular neoplasms and 72.5% of papillary carcinoma were classified to the respective category.

    CONCLUSION: Nuclear morphometry, including texture analysis, can assist in the cytologic diagnosis of thyroid lesions, considering the high degree of accuracy of classification. Further studies and methodological refinements can achieve higher accuracy.

    INTRODUCTION: Cribriform-morular variant (CMV) is a rare variant of papillary thyroid carcinoma. It frequently occurs in association with familial adenomatous polyposis (FAP), although some cases are sporadic. Herein, we report a case of CMV and analyse morule cytohistology.

    CASE REPORT: The patient was a 47-year-old woman with no familial history of FAP. A 3.0-cm unifocal mass was identified in the left thyroidal lobe. Fine-needle aspiration cytology revealed papillary clusters of atypical cells with nuclear grooves, which was suspected to be conventional papillary thyroid carcinoma. Histologically, the tumour comprised a papillary and cribriform growth of atypical cells with cytoplasmic accumulation and nuclear translocation of b-catenin. In addition, frequent morule formation was identified.

    DISCUSSION: In this case, we performed morule analysis through correlative light and electron microscopy (CLEM), and revealed its ultrastructure. Although CMV is a rare form of thyroid carcinoma, it should be considered along with its distinct clinicopathological characteristics.

    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.

    A 60-year-old female developed a right parotid swelling six months after surgery for intra-oral squamous cell carcinoma. Fine needle aspiration (FNA) cytological smears showed dissociated large and small pleomorphic tumour cells with abundant mitoses and oncocytic features. A cytological diagnosis of parotid acinic cell carcinoma (ACC) was made. Histological study of the subtotal parotidectomy specimen showed a papillary cystic variety of acinic cell carcinoma (ACC-PCV). FNA cytological features in this case of ACC-PCV differs from the two previously reported cases in that it showed prominent oncocytic and high grade features and absence of papillary pattern in the cytological smears. ACC-PCV is an uncommon tumour and knowledge of its varied FNA cytological features is important for the diagnosis of this neoplasm.

    INTRODUCTION: Thyroid carcinoma is classically diagnosed based on certain histological criteria. In some cases, definitive diagnoses may be challenging when morphological features are equivocal. This study evaluated the usefulness of Cytokeratin 19 (CK 19) as an immunohistochemical marker to differentiate the different histological types of malignant thyroid neoplasms, particularly papillary thyroid carcinoma (PTC) from benign thyroid lesions.

    MATERIALS AND METHODS: We collected 54 malignant and 65 benign thyroid lesions diagnosed by histology in Universiti Kebangsaan Malaysia Medical Centre between January 2010 and December 2015. All cases were immunohistochemically stained with CK 19 and evaluated by 3 independent observers. The immunostaining patterns were scored based on the intensity and proportion of staining and finally graded as negative, weak positive, moderate positive or strong positive. In addition, the immunostaining scores of the malignant cases were correlated with their TNM pathological tumour stages.

    RESULTS: Cytokeratin 19 staining expression was higher in malignant than benign thyroid lesions (p < 0.001) which was most prominent among classical PTC. The four PTC cases that showed negative or weak staining were all follicular variant of PTC. Benign conditions were mostly negative or showed weak positivity. There was no correlation between CK 19 expression and TNM primary tumour stage (pT).

    CONCLUSION: Cytokeratin 19 is a useful marker in differentiating malignant from benign thyroid conditions particularly the classical PTC, provided its interpretation is by correlation with morphology and takes into consideration the intensity and proportion of positive staining.

    A patient is said to have subclinical hyperthyroidism if he has a depressed thyroid stimulating hormone (TSH) level but is clinically euthyroid and has a normal thyroxine (T4) and triiodothyronine (T3) level. The aetiology of this condition is unknown, its progression is uncertain and the value of treatment is doubtful. These 2 cases show a rapid reversal of TSH suppression within a week after thyroidectomy. This suggest an unidentified potent but innocuous suppressor of TSH is produced by some large nodular goitres. Patients with multinodular goitres with subclinical hyperthyroidism can have their anxiety allayed with assurance that their condition is benign and that their TSH suppression is due to the presence of an innocuous substance which is protective in nature. This substance, when isolated, will find a useful place in the prevention and treatment of papillary carcinoma of the thyroid because of its potent effect on the pituitary-thyroid axis without causing any peripheral effects.
