    Background and Objectives: Currently, pancreatic cystic lesions (PCLs) are recognized with increasing frequency and have become a more common finding in clinical practice. EUS is challenging in the diagnosis of PCLs and evidence-based decisions are lacking in its application. This study aimed to develop strong recommendations for the use of EUS in the diagnosis of PCLs, based on the experience of experts in the field.

    Methods: A survey regarding the practice of EUS in the evaluation of PCLs was drafted by the committee member of the International Society of EUS Task Force (ISEUS-TF). It was disseminated to experts of EUS who were also members of the ISEUS-TF. In some cases, percentage agreement with some statements was calculated; in others, the options with the greatest numbers of responses were summarized.

    Results: Fifteen questions were extracted and disseminated among 60 experts for the survey. Fifty-three experts completed the survey within the specified time frame. The average volume of EUS cases at the experts' institutions is 988.5 cases per year.

    Conclusion: Despite the limitations of EUS alone in the morphologic diagnosis of PCLs, the results of the survey indicate that EUS-guided fine-needle aspiration is widely expected to become a more valuable method.

    In Malaysia, transbronchial needle aspiration (TBNA) is a relatively new procedure performed only in a handful of respiratory centres. We reviewed TBNA of mediastinal lymph node performed in Hospital Tengku Ampuan Afzan (HTAA) to determine the yield and its complications. Data was retrieved from endoscopy databases and patients' records, CT thorax images and all cytological and histological slides were reviewed. Twenty-five patients had TBNA performed. TBNA was positive in 15 patients (60%). Overall, 80% had confirmed malignancy after bronchoscopy. Only four patients had documented bleeding after TBNA and in two of them, bleeding stopped spontaneously and another two patients required diluted adrenaline to stop the bleed. No mortality was reported from this procedure. Hence, TBNA is a safe procedure.

    BACKGROUND: Thyroid Imaging Reporting Data System (TI-RADS) is used to characterize thyroid nodules while reducing unnecessary FNAC. Over the years, several versions of TI-RADS have been developed but there is no consensus on which TI-RADS is the best system. This study aimed to compare the diagnostic accuracy and ability of ACR TI-RADS, EU TI-RADS, K TI-RADS, AI TI-RADS to eliminate unnecessary FNAC.

    METHODS: In this prospective study, thyroid nodules were characterized by using the four TI-RADS systems and US-guided FNAC was done for nodule with the highest ACR TI-RADS score. Correlation between TI-RADS and FNAC results were analyzed.

    RESULTS: Out of 244 thyroid nodules, 100 nodules with either size <1 cm (43 nodules) non-diagnostic or inconclusive FNAC results (57 nodules) were excluded. Seven nodules (4.9%) were confirmed to be malignant on FNAC. K TI-RADS showed 100% sensitivity and NPV but the lowest specificity (40.2%). EU TI-RADS had the highest specificity (83.2%) but the lowest sensitivity (57.1%) and NPV (97.4%). ACR TI-RADS had an average sensitivity (85.7%) and NPV (98.6%). The specificity of ACR TI-RADS (51.1%) was lower than EU TI-RADS but higher than K TI-RADS. AI TI-RADS showed higher specificity (61.8% vs 51.1%, p

    A case of signet-ring cell lymphoma diagnosed initially by fine needle aspiration cytology is reported. This rare tumor is a variant of follicular lymphoma, which closely resembles metastatic adenocarcinoma and other tumors which exhibit signet-ring cell appearance. Correct diagnosis can be achieved by careful morphologic analysis together with positive reactivity with lymphoid markers. The cytohistologic, immunohistochemical and electron microscopic features are described, and the differ ential diagnostic considerations are discussed in the report.

    Thyroid nodules are common but thyroid malignancies are not. Fine needle aspiration (FNA) cytology is a diagnostic tool used to screen patients with thyroid nodules who require surgery. We study the diagnostic accuracy of FNA as the initial diagnostic modality in the clinical assessment of thyroid nodules. Between January 1995 until December 2000, 2131 FNA of thyroid nodules were performed. Four hundred and forty-one (20.7%) of these were unsatisfactory and 1690 (79.3%) cases were satisfactory for cytological evaluation. Histopathological diagnosis were available for 361 cases. Cyto-histopathological correlation was carried out  for these cases. Our results showed a diagnostic accuracy of 96.2% with sensitivity and specificity rates of 87.7% and 98.4% res- pectively. Our positive predictive value is  93.4% and our negative  predictive value is 96.8%.  From this study, we conclude that fine needle aspiration is an important initial screening diagnostic tool for the investigation of thyroid nodules.

    Kimura’s disease (KD) is a rare, benign chronic inflammatory disease of unknown aetiology, typically presents in the Orientals as subcutaneous masses in the head and neck region that could be easily misdiagnosed as a malignant tumour, leading to unnecessary radical surgery or intensive cytotoxic therapy. It has been mainly reported in the Chinese and Japanese literature. It is difficult to diagnose before tissue biopsy and fine needle aspiration cytology (FNAC) has limited value. Hence, unless the pathologists are aware of this entity, it might be mistaken as a malignant lesion. We encountered a case of KD in a Malay patient presenting as a parotid mass that was initially diagnosed as Hodgkin’s lymphoma (HL). This disorder should be suspected in young male Asian patients presenting with a painless unilateral mass in the head and neck region with associated hypereosinophilia.

    Metastases to the breast from non-mammary malignant neoplasm are relatively rare. We report a case of metastatic disease to the breast from a primary lung adenocarcinoma in a young 22-year-old lady. Computed tomography of the thorax confirmed right upper lobe mass with multiple lung nodules and a breast lump. The diagnosis of breast metastasis was confirmed by fine needle aspiration cytology of the breast lump with histopathological findings and immunohistochemical features consistent with lung adenocarcinoma.

    Percutaneous biopsy in breast cancer has been associated with an increased risk of malignant cell seeding. However, the importance of these observations remains obscure due to lack of corroborating evidence from clinical studies. We determined whether method of biopsy is associated with breast cancer survival. This hospital registry-based cohort study included 3416 non-metastatic breast cancer patients diagnosed from 1993 to 2011 in a tertiary setting. Factors associated with biopsy methods were assessed. Multivariable Cox regression analysis was used to determine the independent prognostic impact of method of biopsy. Overall, 990 patients were diagnosed by core needle biopsy (CNB), 1364 by fine needle aspiration cytology (FNAC), and 1062 by excision biopsy. Excision biopsy was significantly associated with more favorable tumor characteristics. Radiotherapy modified the prognostic impact of biopsy method (Pinteraction

    Histoplasmosis infection is endemic in Asia and disseminated histoplasmosis (DH) is one form of its presentation (Benevides et al., 2007[1]). DH commonly affects both adrenal glands. We describe a case of disseminated histoplasmosis complicated with hypercalcaemia in a 75-year-old immunosuppressed patient who presented with bilateral adrenal masses. The fine needle aspiration cytology of the adrenal mass was positive for Histoplasma capsulatum.

    We report a case of tuberculosis of the thyroid gland associated with mediastinal lymphadenitis in a 30 years-old male, who presented with dysphagia and a mid line anterior neck swelling. Fine needle aspiration was positive for acid fast bacilli. He made an uneventful recovery with antituberculous drugs. Although seldom observed, tuberculosis should be kept in mind in te differential diagnisis of nodular lesions of the thyroid.

    Kimura's disease is a rare condition and typically presents as non-tender subcutaneous swellings in the head and neck region, usually in the pre-auricular and submandibular areas. It is associated with lymphadenopathy (both local and distal), marked peripheral eosinophilia, and an elevated IgE level. It can easily be mistaken for a malignant disorder. Fine needle aspiration can be misleading, and a diagnosis is established only by histopathological examination. Renal involvement, which may affect up to 60% of patients, is the only systemic manifestation. We report a case of Kimura's disease in a Malay patient who was associated with steroid-responsive nephrotic syndrome.

    Fine needle aspiration cytology under radiologic guidance for diagnosis of renal cell carcinoma is well established and is increasingly utilized. This is because renal cell carcinoma displays fairly characteristic cellular features permitting correct cytologic identification. We present a case of a 66-year-old man who had advanced renal cell carcinoma with spread to aortic and cervical lymph nodes, lungs and liver. Fine needle aspiration cytology of the para-aortic mass showed tight clusters of malignant cells with abundant and vacuolated cytoplasm consistent with renal cell carcinoma. Histology of the left cervical lymph nodes together with immunohistochemistry findings were consistent with the cytologic diagnosis of metastatic renal cell carcinoma. The patient succumb to his illness three years after the diagnosis was made.

    We report a rare case of undifferentiated (embryonal) sarcoma of the liver in a six-year-old girl who at presentation, had fever, right hypochondrium pain and hepatomegaly. The diagnosis was clinched by fine needle aspiration cytology and was subsequently reconfirmed by histopathological examination of the resected tumour. Pre-operative chemotherapy was given because primary resection was deemed not possible. The patient underwent a successful extensive hepatectomy followed by continuation chemotherapy

    Pilomatrixoma is a benign tumour that originates from the matrix of the hair root. This rare tumour is usually managed by the dermatologists. The commonest location of this tumour is in the head and neck region; hence, it can be encountered by any doctors with interest in this area. When presented in the neck, this hard tumour may pose a diagnostic challenge. A case report of pilomatrixoma misdiagnosed as a metastatic neck disease from fine-needle aspiration cytology is presented. The mistake in the diagnosis has led to a more aggressive and high morbidity surgery than necessary. It is important that head and neck doctors be aware of this condition and includes it in the differential diagnosis of hard masses presenting in the neck.

    Background: Thyroid swelling or goitre is a common condition, either asymptomatic or symptomatic. The
    diagnosis is usually established by ultrasound or fine needle aspiration cytology (FNAC) as a gold standard.
    The sensitivity of the test is inversely related to increasing size of the nodule. The objective of this study is
    to evaluate the accuracy of FNAC especially in cases of large goitre.

    Material and methods: This is a
    retrospective study on patients who underwent thyroidectomy between January 2000 to December 2007 for
    solitary or dominant nodular goitre. The analysis was made only on those patients with complete data on
    FNAC and histology.

    Result: There were 235 patients, but only 161 patients were analysed after excluding
    the suspicious and inadequate sample. The patients’ mean age was 42.1 year old (21 to 60). The size of the
    thyroid nodule ranged from 2.1 to 5.0 cm (mean = 3.9 cm). The overall sensitivity was 67.4% and the overall
    accuracy was 86.3%. The accuracy of FNAC according to the sizes above and below the value were as
    follows; 2 cm (72.2% vs. 88.1%); 3 cm (88.0% vs. 87.4%) ; 4 cm (86.6% vs. 84.4%) ; 5 cm (87.3% vs. 78.8%).
    This was most obvious in the sensitivity of the FNA which also showed reducing trend as the nodules
    increased in size.

    Conclusion: FNAC is an essential diagnostic tool in the management of nodular goitre.
    Our study showed that the accuracy of FNAC decreased as the size of the nodule getting bigger. Cautious
    approach should be taken in the management of large goitre and decision should not be based only on the
    result of FNAC.

    Parotid gland surgery can be challenging due to intricate relationship between the gland and facial nerve. Besides complete removal of the lesion, the main focus of surgery is centered on the facial nerve. Surgery can be technically demanding especially when the tumor is large or involves the deep lobe. We report a patient with a 30-year history of gigantic parotid mass, which initial fine-needle aspiration cytology reported as pleomorphic adenoma. The tumor, weighing 1.3 kg, was successfully resected with facial nerve preservation. Histopathological examination of the excised mass confirmed as carcinoma ex pleomorphic adenoma (CaExPA) of adenocarcinoma, not otherwise specified type. We describe the specific surgical and reconstruction techniques for successful removal of large parotid tumors with facial nerve preservation. To our knowledge, this is the heaviest CaExPA of the parotid gland in South-East Asian region.

    BACKGROUND: Melioidosis, the infection caused by Burkholderia pseudomallei, is associated with a high case fatality rate, due in part to difficulties in clinical recognition and diagnostic confirmation of the disease. Although head and neck involvement is common in children, specific disease manifestations differ between geographic regions. The aim of this study was to provide a detailed description of melioidosis of the head and neck among children in Sarawak, Malaysia, and determine if fine-needle aspiration of suspected head or neck lesions could improve melioidosis diagnosis.

    METHODS: We conducted a retrospective descriptive study of all children aged Fine-needle aspiration of head and neck lesions suspected to be due to melioidosis with inoculation in blood culture bottles (FNA + BCB) was used from the beginning of 2016.

    RESULTS: Of 34 children with culture-confirmed melioidosis, 20 (59%) had an infection involving one or more sites in the head and neck. Of these, 17 (85%) were diagnosed in or after 2016. Cervical lymph nodes were the most common organ or site affected, involved in 19 (95%) children. Clinical presentations of B. pseudomallei lymph node infections were highly variable. Five (25%) children had salivary gland involvement. Lacrimal gland involvement (dacryocystitis) and skin or soft tissue infection (scalp abscess) were less frequent. B. pseudomallei was isolated from the head or neck using FNA + BCB in 15 (75%) children and by standard culture methods of direct plating of pus on agar following incision and drainage in only 2 (10%) children. B. pseudomallei was isolated from non-head or neck specimens or blood in 3 (15%) children.

    CONCLUSIONS: Manifestations of pediatric head and neck melioidosis in Sarawak, Malaysia, differ from those of other regions. Fine-needle aspiration, mainly of affected cervical lymph nodes, facilitates B. pseudomallei detection and enables confirmation of melioidosis infections.
