Invasive aspergillosis of gastrointestinal debut without apparent respiratory involvement in an immunocompetent host.

A 72-year-old female presented with abdominal pain and constipation and intestinal dilation was found. Abdominal computed tomography showed two areas of thickening and stenosis in the proximal jejunum and preterminal ileum, with an unknown etiology. Exploratory laparotomy was proposed but the patient suffered a sudden and progressive decrease in consciousness. Cranial computed tomography showed an ischemic area and a midline shift. Brain biopsies suggested infection by Aspergillus Fumigatus. Despite antifungal drugs, the patient had a progressive clinical deterioration and died. The autopsy concluded a systemic infection due to Aspergillus Fumigatus. Invasive aspergillosis is a serious fungal infection and usually occurs in immunocompromised patients. It mainly affects the lungs, followed by the gastrointestinal tract. The most frequent location in gastrointestinal involvement is the small bowel. Gastrointestinal involvement is more frequent in invasive disease. Although, there are case reports of isolated gastrointestinal aspergillosis, even in immunocompetent patients without risk factors. The prognosis is poor.

Enteroscopy in the diagnosis of melanoma metastases.

We present abdominal computed tomography and enteroscopy images of a 48-year-old male patient with a previous melanoma who presented with epigastric pain. The pain was not controlled with medical management. Abdominal computed tomography and a histological study of biopsies form enteroscopy confirmed the diagnosis of metastatic melanoma. The gastrointestinal involvement of melanoma is usually metastatic. Symptomatic gastrointestinal involvement occurs in less than 5% of melanomas, although postmortem analyses have reported up to 70%. The clinical presentation is variable and usually presents as abdominal pain. The diagnosis of small intestinal involvement of melanoma is a challenge due to its poor accessibility. The enteroscopy has a fundamental role as it allows a direct visualization and biopsies to be taken for histological study.

Enteroscopic diagnosis of intestinal malabsorption of a rare etiology: diaphragm disease.

We present the case of a 59-year-old patient with malabsorption syndrome which started with polyneuropathy. Capsule endoscopy and enteroscopy show villous denudation. Histological study confirms diaphragm disease of the small bowel. Diaphragm disease is a rare disease characterized by the presence of multiple thin diaphragms, such as septa, that narrow the intestinal lumen. The clinical features can be iron deficiency anemia, intestinal obstruction, change in bowel habits or acute abdomen secondary to perforation. It is usually generally with sustained use of high doses of non-steroidal anti-inflammatory drugs. The diagnosis usually requires the use of a capsule endoscopy or enteroscopy with biopsies.

Familial dysphagia: eosinophilic esophagitis.

We present a family with several cases of eosinophilic esophagitis. Some cases of eosinophilic esophagitis in the same family have been previously described. Patients with eosinophilic esophagitis present frequently atopy, and atopy has a strong family association due to complex interactions between genetic and environment. However, eosinophilic esophagitis has a stronger genetic component than other atopic diseases. Eosinophilic esophagitis has been linked to variations in genes like eotaxin-3, TSLP and its receptor and CAPN14, although the inheritance pattern has not yet well defined.

Hepatic hematoma after ERCP: two new case reports.

ERCP is an endoscopic procedure with a complication risk ranging from 2.5 to 8%. The most frequent complications are pancreatitis, cholangitis, hemorrhage or perforation. Hepatic hematoma after ERCP is a potentially serious, rare complication. Not many cases are reported in the literature. We present here two new cases of hepatic hematoma following ERCP along with a review of the literature and possible therapeutic options.
