A 70-year-old male was referred with hyperthyroidism and multinodular goiter (MNG). Thyroid ultrasonography showed 2 nodules, one in the isthmus and the other in the left lobe, 51 and 38 mm in diameter, respectively. Neck CT showed a large MNG, thyroid scintigraphy showed increased uptake in the nodule in the left lobe, and fine-needle aspiration biopsy showed a benign cytology of the nodule in...

OBJECTIVES To ascertain if there has been a change in the pattern of thyroid cancer in Sri Lanka. If so, whether there is a correlation to the implementation of the programme of iodination. DESIGN Retrospective (1974-1986) and prospective (1987-2001). SETTING Kandy Hospital (1974-1982), Peradeniya Hospital (1982-2001) and private hospitals in Kandy (1979-2001). METHOD Three hundred consec...

Poorly differentiated (insular) thyroid carcinoma (PDITC) is an uncommon thyroglobulin producing neoplasm intermediate in aggressiveness between well-differentiated carcinomas of follicular cell origin and undifferentiated anaplastic carcinoma. Its cytomorphological recognition is essential for planning surgery and subsequent management as it is known for its aggressive behavior, advanced stage...

UDP-N-acetylglucosamine:alpha-mannoside beta-1,6-N-acetylglucosaminyltransferase (GnT-V) catalyzes the formation of beta-1-6 GlcNAc branches on asparagine-linked oligosaccharides, which is directly linked to tumorigenesis. Our recent studies indicate that the secretion of matriptase from cancer cells is increased via the action of GnT-V, as evidenced by the fact that matriptase-bearing beta-1-6...

thyroid tumors producing colony-stimulating factors associated with neutrophilia and/or eosinophilia are very rare and almost all of them concern anaplastic thyroid cancer. Only one case of papillary thyroid carcinoma associated with neutrophilia and one case of medullary thyroid carcinoma associated with eosinophilia have been reported. In this report a 72-year old male patient with metastatic...

BRAF-activating mutations have been reported in several types of cancer, including melanoma ( approximately 70% of cases), thyroid (30-70%), ovarian (15-30%), and colorectal cancer (5-20%). Mutant BRAF has constitutive kinase activity and causes hyperactivation of the mitogen-activated protein kinase pathway. BRAF silencing induces regression of melanoma xenografts, indicating the essential rol...

Carcinoma of the thyroid gland is an uncommon cancer, but one of the most frequent malignancies of the endocrine system. Most thyroid cancers are derived from the follicular cells. Follicular carcinoma is considered more malignant than papillary thyroid carcinoma (PTC), and anaplastic thyroid cancer (ATC) is one of the most lethal human cancers. Even though several genetic lesions have been alr...

BACKGROUND Promyelocytic leukaemia zinc finger (PLZF) is a transcriptional repressor that was originally isolated from a patient with promyelocytic leukaemia. PLZF also affects key elements for cell cycle progression, such as cyclin A, and can affect the tumourigenicity of various cancers. Thus far, the behaviour of PLZF in thyroid carcinoma remains unclear. METHODS We analysed the expression...

AIM To stratify the malignancy risks in thyroid nodules in a tertiary care referral center using the Bethesda system. METHODS From January, 2012 to December, 2014, a retrospective analysis was performed among 1188 patients (15-90 years) who had 1433 thyroid nodules and fine-needle aspiration at Prince Sultan Military Medical City, Saudi Arabia. All thyroid cyto-pathological slides and ultra s...
