A case of uterine fatty tumour of 2 cm studied by transvaginal ultrasound in a 67-year-old woman undergone totally laparoscopic hysterectomy is here presented along with an updated review of this kind of tumours. A total of 226 cases from 75 publications could be found. Traditional definitions of these tumours are here critically reconsidered. The terminology used to define these tumours is confusing and reflects main radiological and pathological points of view (uterine fatty tumours [UFT] vs. lipoma/ lipoleiomyoma). It is here stressed that these tumours by occurring in aged and overweight women are not so uncommon as generally believed, can be very well recognized, as far as they are small (< 4 cm), by transvaginal ultrasound while CT and MR become more specific for decision making in case of larger size tumours. Symptoms largely vary from none to sudden lump enlargement or bleeding or pain. An association with malignancy has been found in 10% suggesting a radical treatment (hysterectomy) in most cases.

Aims —The spectrum of microscopic lesions resulting from the chronic use of non-steroidal anti-inflammatory drugs (NSAIDs), known as chemical gastritis, remains unclear, and the variable prevalence reported in different studies makes this issue a matter of lively debate. The aim of this study was to evaluate the prevalence and importance of chemical gastritis in patients regularly taking NSAIDs. Owing to the high prevalence of Helicobacter pylori infection, particularly in subjects over 60 years of age, and in view of a possible association with damage, the presence of H pylori infection in the same tissue sample was also determined in all patients. Methods —One hundred and ninety seven subjects were enrolled, 118 of whom were receiving chronic treatment with NSAIDs and 79 of whom were controls, pair matched for age, sex, and clinical symptoms (ulcer-like dyspepsia or upper digestive tract haemorrhage). Antral biopsies taken during upper gastroduodenal endoscopy were assessed for chemical gastritis according to a modified version of Dixon9s score, and for helicobacter correlated chronic active gastritis, according to the updated Sydney system. Results —Chemical gastritis was identified in 11 patients taking NSAIDs (9%) and in four controls (5%) (p Helicobacter pylori was detected in 53 patients taking NSAIDs (45%) and in 34 controls (43%). Patients taking NSAIDs had a significantly higher number of erosions and ulcers and worse endoscores than controls. The presence of H pylori did not appear to increase histological damage, ulcer prevalence, or haemorrhagic events. Conclusions —Chemical gastritis is present in a limited number of patients regularly taking NSAIDs, and is not strongly correlated with NSAID induced damage. In many cases of peptic ulcer or upper gastrointestinal bleeding in patients taking NSAIDs, the presence of chemical gastritis or H pylori infection cannot solely account for the development of mucosal damage.

HER2 expression or gene amplification is crucial for performing targeted theraphy. We assessed p185HER2 (p185) expression, HER2 amplification and copy number of chromosome 17 centromere (CEP17) in pancreatic adenocarcinoma (PAC). We analyzed 26 tumours at diagnosis, 21 metastatic lymph nodes (mLN) and 38 distant metastases (mTS) by immunohistochemistry and by FISH. p185 overexpression was shown in 4% of primary PAC, 6% of mLN and 29% of mTS. Amplification was found restricted to 10% of the mTS and increased CEP17 in 21% of mTS and 16% of mLN. Overexpression of p185 was present in all amplified cases but in only 36% of increased CEP17. In conclusion HER2 amplification and increased CEP17 were mainly related to mTS or mLN and increased CEP17 was not always linked to overexpression of p185.

Among malignant neoplasms of the pancreas, lymphomas have a very low incidence. Nevertheless, the dramatic difference in prognosis and treatment between pancreatic carcinoma and lymphoma stresses the importance of a correct diagnosis, especially because most lymphomas of the biliopancreatic region are low-grade B-cell type. The case observed by us shares clinical and pathological features with the few previously reported in literature, and focuses clinicians' attention on the diagnosis of this unusual neoplasm whose clinical behaviour is characterized by obstructive jaundice and overlaps with that of epithelial tumours.
