background: visfatin is an adipocytokine secreted by visceral adipose tissue. it has been shown that adipocytokines may contribute to the induction of carcinogens and progression of tumors. previously, we found a significant increase in the visfatin serum level in colorectal cancer patients. herein, we investigated if this cytokine increases in patients with colorectal adenoma as a precursor of...

introduction: the co-existence of pituitary adenoma and meningioma is extremely rare. it is even rarer in patients with no previous known risk factors for either tumour. here, we present a case of synchronous non-functioning pituitary adenoma with suprasellar and olfactory groove meningiomas in a patient without previous irradiation. methods: the tumours were diagnosed on mri in the 65-year-old...

Salivary gland tumors are among the pathologies in the head and neck that may be challenging in diagnosis and treatment. Most benign tumors occur in the parotid gland. Pleomorphic Adenoma is the most common type. Basal Cell Adenoma is a subtype of the Monomorphic Adenoma with rare occurrence. Proper diagnosis and clinical evaluation by the use of radiography can lead the physician to the best t...

discussion: the histopathological examination showed increased number of acini with preserved duct-acinar connection, consistent with nodular hyperplasia. the patient had used oral contraceptive pill for four years. introduction: tumors which originate from the bartholin’s glands (bgs) are very rare. many solid masses that arise from the bgs are carcinoma, though these benign solid lesions are ...

OBJECTIVE: To report a case of pleomorphic adenoma that was surgically removed and to describe the surgical technique available remove this lesion. CASE REPORT: A male patient, caucasian, 46 years old, with 4-year history adenoma. He mentioned he went other services for treatment, but without success. came at our service treatment tumoral excision. Local anesthesia performed mepivacaine vasocon...

Nuclear diameter was measured in 55 parathyroid chief-cell adenomas to determine its value in histological diagnosis and to assess its relationship to other features of primary hyperparathyroidism. Mean nuclear diameter for the whole group of adenomas was significantly greater than that for the accompanying normal glands. Mean nuclear diameter in individual adenomas was significantly greater th...

The weight of evidence points to weak genotoxic activity of methyleugenol, the putative genotoxic carcinogen being 1'-sulphate ester metabolite. Dose response modelling of the data for methyleugenol gave a BMDL10 for male rat liver adenoma or carcinoma (combined) of 7.9 mg/kg-bw/d following adjustment to daily average doses. The MoEs ranged from 100 to 800 depending on the assumptions used in t...

the coexistence of medullary thyroid carcinoma (mtc), papillary thyroid carcinoma (ptc) and parathyroid adenoma is an uncommon clinical entity. here, we report a case of mtc, ptc, and parathyroid adenoma diagnosed incidentally on a routine physical examination of the neck for the work-up of diabetes. the patient had neither symptoms of hypercalcemia nor those related to mtc and ptc.

It is very difficult to differentiate follicular adenoma from follicular carcinoma in thyroid follicular lesions. The authors investigated the biological behavior of these thyroid follicular lesions using immunohistochemical techniques. Specimens taken from normal thyroid, 2 cases; follicular adenoma, 9; atypical adenoma, 7; and follicular carcinoma, 8; were observed. Proliferating cell nuclear...
