Multiple Adenocarcinomas of the Small Bowel in a Patient with Brunner's Glands Agenesia: A Previously Unreported Association.

Adenocarcinoma of the small bowel is rather uncommon and several etio-pathogenic factors have been proposed. We report a case of multiple synchronous adenocarcinomas arising in the non-ampullary duodenum and first tract of the jejunum in a background of Brunner's glands agenesia, chronic duodenitis, and extensive dysplasia in a 64 year-old woman. To the best of our knowledge such association has not been reported so far.

The epidemiology and management of odontogenic keratocysts (OKCs): A European multicenter study.

The objective of the present study was to assess the epidemiology including demographic variables, diagnostic features, and the management of odontogenic keratocyst (OKCs) at several European departments of maxillofacial and oral surgery. This study is based on a systematic computer-assisted database that allowed the recording of data from treated OKCs. The following data were recorded for each patient: gender, age, voluptuary habits, comorbidities, site, size, radiographic features, treatment of OKCs, length of hospital stay, complications, recurrence, management and complications of eventual recurrence.

The epidemiology and management of ameloblastomas: A European multicenter study.

The present study aimed at assessing the epidemiology including demographic variables, diagnostic features, and management of ameloblastomas at several European departments of maxillofacial and oral surgery. The following data were recorded for each patient: gender, age, voluptuary habits, comorbidities, site, size, radiographic features, type, histopathological features, kind of treatment, length of hospital stay, complications, recurrence, management and complications of the recurrence. A total of 244 patients, 134 males and 110 females with ameloblastomas were included in the study.

Mitochondrial DNA "common deletion" in post-fine needle aspiration infarcted oncocytic thyroid tumors.

Thyroid fine needle aspiration (FNA) can rarely induce morphological changes potentially hindering the histopathological diagnosis, especially in Hurthle cell tumors (HCTs), which may easily undergo post-FNA infarction or necrosis. HCTs contain mitochondrion (mt)-rich cells that may bear mtDNA mutations, the most frequent being the so-called common deletion (CD). The aim of this study was to determine the presence and extent of the mtDNA CD in a series of thyroid HCTs that underwent extensive infarction following FNA procedure in comparison with a control series of HCTs lacking post-FNA ischemic/hemorrhagic alterations.
