Mucinous adenocarcinoma of the small bowel is very rare, and only few cases have been described in the literature. Association of this tumor with celiac disease has never been published. The authors report a unique case of jejunal mucinous adenocarcinoma in which a concomitant celiac disease has been histologically recognized. The difficult diagnosis, the role of laparoscopic surgery and the relationship between small bowel tumors and celiac disease are discussed. A 49-year-old man presented with recurrent melena, nausea, vomiting and anemia. A stenosis of the jejunum was documented by means of CT scan and video capsule enteroscopy. A laparoscopy was scheduled. A tumor, found in the first jejunal loop, was removed by laparoscopic surgery. Histopathology revealed a rare mucinous adenocarcinoma associated with epithelial changes secondary to celiac disease. Although small bowel tumors are rare entity, in patients with celiac disease complaining of symptoms related to altered intestinal transit or occult bleeding, an appropriate work-up should be planned for diagnosis. Mucinous type intestinal adenocarcinoma, even if never published before, could be observed. Laparoscopic surgery is often essential for the diagnosis and treatment.

Background. Cystic tumour of the pancreas are infrequent and malignancy of the pancreas during pregnancy is extremely rare. Mucinous cystoadenomas is the most frequent cystic pancreatic neoplasm and it is seen mainly in women suggesting a sex hormone influence. Its presentation during pregnancy is extremely rare and entails difficulties in diagnosis and therapy. Case report. A 28 year old woman was referred to our service for abdominal mass. She had given birth to her second child two weeks previously. Ultrasound and CT scan showed a large cystic lesion, with sepitation and inner solid growth portions, involved mainly the left sovramesocolic space. An ultrasound-guided aspiration of the cystic fluid showed high level of CEA and CA. 19-9. The patient underwent laparotomic body-tail pancreatectomy and splenectomy. The histological examination showed mucinous cystoadenoma with associated invasive ductal carcinoma, with ovarian-like stroma and a well delimited fibrous capsule. Hystochemical study revealed a strong positivity for progesterone receptors. Conclusions. To our knowledge this is the eighth case of mucinous cystoadenoma reported in English literature and the forth with an invasive adenocarcinoma associated. This pathological entity should always be kept in mind in case of patient with an hepigastric mass during or soon after pregnancy. Aggressive approach is mandatory.

The authors present two cases of mucocele of the appendix and discuss them in relation to the literature and the clinical features of this disease. They clarify the definition of mucocele as an intraluminal accumulation of mucus in the appendix, and concentrate on the observable pathological processes, agreeing on the higher frequency of mucinous cystadenoma and the possibility that mucocele can develop into peritoneal pseudomyxoma or degenerate into cystadenocarcinoma. They also note that most diagnoses are made intra-operatively during appendectomy, and that, in cases suspected preoperatively, thorough investigation with imaging techniques is very important in order to plan the best treatment.
