    Follicular adenoma defined as a well encapsulated benign neoplastic condition of thyroid follicles. We describe this interesting case of a boy presented with right sided neck swelling that was diagnosed as a branchial cyst but later after excision, the histopathology revealed follicular adenoma of the thyroid with hemorrhage and degenerative changes in the centre. To our knowledge, this is the first reported case of follicular thyroid adenoma presented as branchial cyst.

    Streptococcus bovis (S. bovis) bacteria are associated with colorectal cancer and adenoma. S. bovis is currently named S. gallolyticus. 25 to 80% of patients with S. bovis/gallolyticus bacteremia have concomitant colorectal tumors. Colonic neoplasia may arise years after the presentation of bacteremia or infectious endocarditis of S. bovis/gallolyticus. The presence of S. bovis/gallolyticus bacteremia and/or endocarditis is also related to the presence of villous or tubular-villous adenomas in the large intestine. In addition, serological relationship of S. gallolyticus with colorectal tumors and direct colonization of S. gallolyticus in tissues of colorectal tumors were found. However, this association is still under controversy and has long been underestimated. Moreover, the etiological versus non-etiological nature of this associationis not settled yet. Therefore, by covering the most of up to date studies, this review attempts to clarify the nature and the core of S. bovis/gallolyicus association with colorectal tumors and analyze the possible underlying mechanisms.

    The seroprevalence of IgG antibodies of Streptococcus gallolyticus subspecies gallolyticus, CIP 105428, was evaluated to investigate the controversial association of S. gallolyticus with colorectal carcinoma and adenoma in attempt to investigate the nature of such association if any, by exploring the mRNA expression of NF-kappaB and IL-8. Moreover, the serological behavior of S. gallolyticus IgG antibodies was compared to that of an indicator bacterium of bowel, Bacteroides fragilis.

    Pachydermoperiostosis is a very rare osteoarthrodermopathic disorder whose clinical and radiographic presentations may mimic those of acromegaly. In the evaluation of patients with acromegaloid appearances, pachydermoperiostosis should be considered as a differential diagnosis. In this article, we report a 17-year-old boy who presented with 2-year history of acral enlargement and facial appearance changes associated with joint pain and excessive sweating. He had been investigated extensively for acromegaly, and the final diagnosis was pachydermoperiostosis.

    LEARNING POINTS: There is a broad range of differential diagnosis for acromegaloid features such as acromegaly, pseudoacromegaly with severe insulin resistance, Marfan's syndrome, McCune-Albright and a rare condition called pachydermoperiostosis.Once a patient is suspected to have acromegaly, the first step is biochemical testing to confirm the clinical diagnosis, followed by radiologic testing to determine the cause of the excess growth hormone (GH) secretion. The cause is a somatotroph adenoma of the pituitary in over 95 percent of cases.The first step is measurement of a serum insulin-like growth factor 1 (IGF1). A normal serum IGF1 concentration is strong evidence that the patient does not have acromegaly.If the serum IGF1 concentration is high (or equivocal), serum GH should be measured after oral glucose administration. Inadequate suppression of GH after a glucose load confirms the diagnosis of acromegaly.Once the presence of excess GH secretion is confirmed, the next step is pituitary magnetic resonance imaging (MRI).Atypical presentation warrants revision of the diagnosis. This patient presented with clubbing with no gigantism, which is expected in adolescent acromegalics as the growth spurt and epiphyseal plate closure have not taken place yet.

    BACKGROUND: A colorectal cancer screening program was piloted in two districts of Kedah in 2013. There is scarcity of information on colorectal cancer screening in Malaysia.

    OBJECTIVE: Thus, this research was conducted to evaluate the colorectal cancer screening program in the districts to provide insights intop its efficacy.

    MATERIALS AND METHODS: A cross sectional study was conducted using data on the colorectal cancer screening program in 2013 involving Kota Setar and Kuala Muda districts in Malaysia. We determined the response rate of immunochemical fecal occult blood test (iFOBT), colonoscopy compliance, and detection rates of neoplasia and carcinoma. We also compared the response of FOBT by demographic background.

    RESULTS: The response rate of FOBT for first iFOBT screening was 94.7% while the second iFOBT screening was 90.7%. Participants from Kuala Muda district were 27 times more likely to default while Indians had a 3 times higher risk of default compared to Malays. The colonoscopy compliance was suboptimal among those with positive iFOBT. The most common finding from colonoscopy was hemorrhoids, followed by tubular adenoma. Detection rate of carcinoma and neoplasia for our program was 1.2%.

    CONCLUSIONS: In summary, the response rate of iFOBT was encouraging but the colonoscopy compliance was suboptimal which led to a considerably low detection rate.

    Primary aldosteronism (PA) causes a persistently elevated blood pressure (BP) due to
    excessive release of the hormone aldosterone from the adrenal glands. Classically, it is called
    Conn’s syndrome and is described as the triad of hypertension and hypokalemia with the
    presence of unilateral adrenal adenoma. It can be cured with surgical resection of the
    aldosterone-secreting adenoma leading to resolution of hypertension, hypokalemia and
    increased cardiovascular risk associated with hyperaldosteronism. We present a case of a man
    with previous ischemic heart disease (IHD) who presented with resistant hypertension.
    Investigations for secondary causes of hypertension revealed an elevated aldosterone level
    and saline suppression test confirmed the diagnosis of PA. Radiological examination revealed
    a left adrenal adenoma and a normal right adrenal gland. However, adrenal venous sampling
    showed lateralization of aldosterone secretion towards the right. He subsequently underwent
    a laparoscopic right adrenalectomy which improved his BP control promptly. This case
    highlights the importance of recognizing the need to investigate for secondary causes of
    hypertension. It also underscores the importance of dynamic tests, which may not be easily
    accessible to most clinicians but should pursue, to allow a definitive diagnosis and effective
    treatment.

    Pancreatic neuroendocrine tumors (PanNETs) are a rare subtype of pancreatic cancer and can be divided into functional (30-40%) and nonfunctional subtypes. The different subtypes of functional PanNETs (F-PanNETs) have a variety of classical presentations that raise suspicion for an underlying PanNET. It is estimated that 90% of PanNETs are sporadic, and the PI3K-Akt-mTOR and ATRX/DAXX signaling pathways have been recognized as key genetic pathways implicated in the pathogenesis. The other 10% of PanNETs may occur in the context of familial cancer syndromes such as MEN1. Chromogranin A is the most useful biomarker currently; however, several studies have shown limitations with its use, especially its prognostic value. Synaptophysin is a novel biomarker which has shown promising preliminary results however its use clinically has yet to be established. Blood tests assessing hormone levels, cross-sectional imaging, and endoscopic ultrasound remain at the core of establishing a diagnosis of F-PanNET. The treatment options for F-PanNETs include surgical methods such as enucleation, systemic therapies like chemotherapy and novel targeted therapies such as everolimus. The prognosis for F-PanNETs is more favorable than for nonfunctional PanNETs, however metastatic disease is associated with poor survival outcomes. Researchers should also focus their efforts on identifying novel pathways implicated in the pathogenesis of F-PanNETs in order to develop new targeted therapies that may reduce the need for surgical intervention and on the establishment of novel biomarkers that may reduce the need for invasive testing and allow for earlier detection of F-PanNETs.

    Parotid tumours represent one of many groups of tumours in the field of
    Otorhinolaryngology. However, a local demographical evaluation of parotid tumours and its annual incidences has never been undertaken. This study intends to review local demography in relation to incidence of parotid tumour seen in Otorhinolaryngology (ORL) clinic, Hospital Tuanku Ja’afar Seremban, Negeri Sembilan from the year 2007 till 2012. Methods: A retrospective demographical study on parotid cases seen in ORL clinic, Hospital Tuanku Ja’afar Seremban between 2007 till 2012 involving 56 cases. Data that was collected include patient details, facial nerve involvement on presentation, type of surgery performed, site of tumour, facial nerve injury post operation and final histopathological diagnosis. Results: An average of 10 cases per year was noted from 2007 to 2012. Male to female ratio was found to be 1.4:1. Age range of sample population were 9 to 79 years old with a mean age of 47 at time of diagnosis. Superficial lobe was found to be the most common tumour site (63%). Majority of cases consists of benign tumours in 51 out of 56 cases with Warthin’s tumour and Pleomorphic Adenoma being the most common histopathological finding. Post operative facial nerve injury were noted in 17 cases in which 13 cases were temporary while 4 others were permanent.

    INTRODUCTION: Benign tumours of the parotid gland constitute about 80% of parotid tumours. The most common benign tumour of the parotid gland is pleomorphic adenoma. Other conditions, like Kimura's disease, may mimic a tumour when they present as a parotid mass. Various modes of treatment have been advocated for the treatment of benign parotid lesions, ranging from enucleation to near-total parotidectomy.

    MATERIAL AND METHODS: This is an audit of an 18-year period where 173 lesions of the parotid gland (34 malignant and 139 benign lesions) were treated by the author.

    RESULTS: There were 139 benign lesions, of which 123 were benign tumours and 16 non-tumour conditions. Fourteen cases of recurrent pleomorphic adenoma of parotid that had been treated elsewhere were also operated on. Near-total parotidectomy was performed on all these cases with benign lesions.

    CONCLUSIONS: There has been no recurrence in all the patients who was treated this way. Near-total parotidectomy should be considered when there is a need to treat benign parotid swellings.

    Primary tracheal tumors are very rare. Pleomorphic adenoma is rarely found in the trachea, despite being the most common histological form of salivary gland neoplasm. We present a case of pleomorphic adenoma of the trachea. Bronchoscopic excision using cold instruments resulted in apparently normal tracheal mucosa.

    Aldosterone-producing adenoma (APA) is a common curable cause of hypertension. Somatic mutations in five genes (KCNJ5, ATP1A1, ATP2B3, CACNA1D, and CTNNB1) have been found to cause the excess aldosterone production of two thirds of APAs [1-4]. KCNJ5 mutant APAs, the most common and largest, had explicit genotype-phenotype relationship - a low protein expression of KCNJ5 relative to their peritumoural zona glomerulosa (ZG) and a zona fasciculata-like composition [5-6]. Conversely for the other genes, controversy arises on whether they have the opposite cell phenotype [4,7-8]. This prospective study aim to to characterize the histopathological-specific mutation spectrum of APAs.

    In situ coating of 5-fluorouracil pellets by ethylcellulose and pectin powder mixture (8:3 weight ratio) in capsule at simulated gastrointestinal media provides colon-specific drug release in vitro. This study probes into pharmacodynamic and pharmacokinetic profiles of intra-capsular pellets coated in vivo in rats with reference to their site-specific drug release outcomes. The pellets were prepared by extrusion-spheronization technique. In vitro drug content, drug release, in vivo pharmacokinetics, local colonic drug content, tumor, aberrant crypt foci, systemic hematology and clinical chemistry profiles of coated and uncoated pellets were examined against unprocessed drug. In vivo pellet coating led to reduced drug bioavailability and enhanced drug accumulation at colon (179.13 μg 5-FU/g rat colon content vs 4.66 μg/g of conventional in vitro film-coated pellets at 15 mg/kg dose). The in vivo coated pellets reduced tumor number and size, through reforming tubular epithelium with basement membrane and restricting expression of cancer from adenoma to adenocarcinoma. Unlike uncoated pellets and unprocessed drug, the coated pellets eliminated aberrant crypt foci which represented a putative preneoplastic lesion in colon cancer. They did not inflict additional systemic toxicity. In vivo pellet coating to orally target 5-fluorouracil delivery at cancerous colon is a feasible therapeutic treatment approach.

    INTRODUCTION: Although the majority of patients with primary hyperparathyroidism have a relatively asymptomatic benign disorder, there are patients who have a more aggressive disorder.

    CLINICAL PICTURE: We report a case of primary hyperparathyroidism presenting during pregnancy complicated by antepartum haemorrhage and severe prematurity. The diagnosis was made postpartum, when her problems rapidly progressed to result in severe neuromuscular weakness, bilateral pathological hip fractures as well as nephrolithiasis.

    TREATMENT: Surgical parathyroidectomy was performed. The underlying lesion was a large solitary parathyroid adenoma with cystic elements.

    CONCLUSION: Primary hyperparathyroidism is not an innocuous disease and can result in severe morbidity if left untreated.

    An adrenal incidentaloma is defined as an adrenal mass measuring at least 1 cm that is discovered surreptitiously in an imaging study done for reasons other than the evaluation of adrenal disease. The increase in the prevalence of adrenal incidentalomas has paralleled the increase in diagnostic imaging done for evaluation of other abdominal pathologies. However, most of these adrenal incidentalomas are benign non-hyperfunctioning adenomas. When an adrenal incidentaloma is discovered, the simultaneous presence of hypokalemia, metabolic alkalosis, mild hypernatremia, and mild to severe drug-resistant hypertension may alert a clinician to underlying primary hyperaldosteronism. We present a case of adrenal incidentaloma noted in a patient with end-stage renal disease on hemodialysis which presented a diagnostic challenge due to the correction of metabolic parameters with hemodialysis. The patient was found to have an aldosterone-producing adenoma based on an elevated aldosterone-to-renin ratio and was started on a mineralocorticoid antagonist.

    PURPOSE: Guaiac fecal occult blood test (gFOBT) has been the standard for colorectal screening but it has low sensitivity and specificity. This study evaluated the use of fecal tumor M2-pyruvate kinase (M2-PK) for detection of colorectal cancer and to compare with the current surveillance tool; gFOBT in symptomatic adult subjects underwent colonoscopy.

    METHODS: Stool samples were collected prospectively from symptomatic adults who had elective colonoscopy from September 2014 to January 2016 and were analyzed with the ScheBo M2-PK Quick test and laboratory detection of fecal hemoglobin.

    RESULTS: The results were correlated to the colonoscopy findings and/or histopathology report. Eighty-five subjects (age of 56.8 ± 15.3 years [mean ± standard deviation]) were recruited with a total of 17 colorectal cancer (20.0%) and 10 colorectal adenoma patients (11.8%). The sensitivity of M2-PK test in colorectal cancer detection was higher than gFOBT (100% vs. 64.7%). M2-PK test had a lower specificity when compared to gFOBT (72.5% vs. 88.2%) in colorectal cancer detection. The positive and negative predictive values were 47.2% and 100% for M2-PK test and 57.9% and 90.9% for gFOBT.

    CONCLUSION: Fecal M2-PK Quick test has a high sensitivity for detection of colorectal cancer when compared to gFOBT, making it the potential choice for colorectal tumor screening biomarker in the future.

    Colonoscopy is an integral part of the clinician armamentarium in the diagnosis of colorectal cancer and its precursor, the adenoma. Polypoid lesions when identified can be excised at colonoscopy and in turn reduce the risk of colorectal cancer. We prospectively evaluated the yield of colorectal cancer and adenomatous polyps by indication for colonoscopy over a one-year period. A total of 375 colonoscopies were carried out. The more common indications of colonoscopy were rectal bleeding, abdominal pain, surveillance of colorectal cancer and altered bowel habit. The highest yield for cancer was for rectal bleeding with 12.5% while surveillance of patients with a history of polyps yielded the highest percentage of new polyps. We conclude that rectal bleeding as an indication for colonoscopy yielded the highest number of cancers.

    Pleomorphic adenoma is the most common type of benign salivary gland tumor. It can also be found in the larynx, ear, neck, and nasal septum. It is rarely found in the maxillary sinus, and it has never been reported in the frontal sinus. We report a case of pleomorphic adenoma of the frontal sinus that masqueraded as a mucocele. We discuss the clinical presentation, diagnosis, and treatment of this patient, and we review the literature.

    Aneusomy is an early genetic event and a characteristic feature of many solid tumors. It is often associated with poor prognosis in cancer patients. The involvement of PAX8-PPARγ rearrangement in tumorigenesis of follicular thyroid lesions has been widely assessed. However, there were few reports on aneusomy of the PPARγ gene at the 3p25 locus in follicular thyroid lesions. It remains undetermined whether these abnormalities can be translated into improved diagnosis, classification, or outcome prediction. Herein, we report three cases of follicular thyroid neoplasms [two follicular thyroid carcinomas (FTCs) and one Hurthle cell adenoma (HCA)] with 3p25 aneusomy detected by fluorescence in situ hybridization (FISH). 3p25 trisomy was observed in one FTC and one HCA while 3p25 tetrasomy was observed in one FTC. Furthermore, all three lesions did not show overexpression of PPARγ protein. Hurthle cell neoplasms (HCN) are distinct clinically and histologically from other follicular thyroid neoplasms (FTN). However, the presence of the aneusomy in HCA and FTC indicates that there could be a biological continuum between the two and chromosomal gains might play an important role in the pathogenesis of these two types of neoplasms. Despite their differences, HCN and FTN may share the same early genetic event in tumour development.
