Introduction: Pleomorphic adenoma of the upper lip is a rare entity and its diagnosis requires a high index of suspicion. The aim of this study was to review the reported cases of pleomorphic adenoma (PA) of the upper lip. Methods: This study was performed on the basis of the clinical features of 10 well-documented reported cases of the upper lip pleomorphic adenomas from 1990 to 2012 which hav...

BACKGROUND/AIMS The relationship between adipocytokines and the development of colorectal cancer is well-documented. Our aim was to assess the relationship among serum adiponectin and resistin levels, insulin resistance, and colorectal adenoma to evaluate whether these parameters can be used as biomarkers to predict the development of colorectal adenoma. MATERIALS AND METHODS This is a cross-...

The authors examined the association between circulating 25-hydroxyvitamin D(3) (25(OH)D(3)), the best indicator of total vitamin D exposure, and incident, sporadic colorectal adenoma risk in a pooled analysis of primary data from 3 colonoscopy-based case-control studies conducted in Minnesota, North Carolina, and South Carolina between 1991 and 2002. The pooled study included 616 colorectal ad...

Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign sweat gland tumors. Syringocystadenoma papilliferum occurs alone or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. However, the co-existence of these two tumors witho...

OBJECTIVES Ceruminous adenoma of the external auditory canal (EAC) is a rare type of tumour that is diagnosed histologically. However, the clinical behaviour of these tumours remains controversial. Here, we report a case of ceruminous adenoma of the EAC and expression of a hypoxia marker. CASE REPORT A 78-year-old man presented with a 6-month history of recurrent otorrhoea in the right ear. S...

Lignans and proanthocyanidins are plant polyphenols that have shown protective properties against colorectal neoplasms in some human studies. Using logistic regression, we estimated odds ratios (ORs) and 95% confidence intervals (CIs) to prospectively evaluate the association between lignan and proanthocyanidin intake, estimated from databases linked to a food frequency questionnaire, and adeno...

Pleomorphic adenoma, also known as benign mixed tumor, is the most common tumor affecting the parotid gland and can reach massive size; however, intracranial invasion is rare. Recurrence of pleomorphic adenoma after excision is a well-known phenomenon and can present decades after resection of the primary tumor. Here we present the case of a 53-year-old man who presented to our clinic with ear ...

The histopathology of 12 patients with adenoma of the ampulla of Vater was examined to trace the adenoma-carcinoma sequence of the ampulla of Vater. Immunohistochemistry for carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 was also performed. Four large adenomas with mild dysplasia also had foci of moderate dysplasia while another one contained foci of severe dysplasia (intramu...

Other than that in the duodenum, adenocarcinoma in the small bowel is rare. The present study describes a case of adenocarcinoma with adenoma in the jejunum. A 70-year-old male was admitted to hospital due to dehydration induced by abdominal discomfort and difficulty with oral intake. Computed tomography revealed a tumor in the upper side of the jejunum, which was subsequently resected. The tum...

OBJECTIVE To determine whether pituitary adenomas can be diagnosed by identifying protein biomarkers in the serum. METHODS We compared serum proteins from 65 pituitary adenoma patients and 90 healthy donors using proteomic fingerprint technology combining magnetic beads with matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS). RESULTS A total of 42 M/...
