HighlightsIntestinal intussusception in adults is rare, accounting for approximately 1% of all bowel obstructions.Colo-colonic intussusception accounts for 17% of cases.The occurrence of large lipomatous masses as cause of intussusception and semi-obstructive symptoms remains rare.The case that we describe is particularly unique because apart from being an example of intussusception in adults, it occurred in the sigmoid colon and was not associated with a malignant lesion.

The skeleton is a common metastatic site for visceral carcinomas. However, the presentation of gastric cancer as bony metastases without preceding gastrointestinal symptoms is rare which has been infrequently reported in the literature. We report an infrequent case of a 60-year-old patient diagnosed having a gastric carcinoma with bone metastasis as the first evidence. She has consulted with worsening backache which started two months priorly.

Primary hepatic lymphoma is a rare disease, accounting for only 0.1% of malignant liver tumors. The subtype of diffuse large B-cell lymphoma (DLBCL) is more infrequent. In contrast to hepatitis C virus, the association between hepatitis B virus and lymphoma is less clear. Here, we report the case of a 52-year-old patient followed for chronic hepatitis B complicated by cirrhosis, associated with a primary hepatic DLBCL, with a good response to chemotherapy.

Esophageal intramural pseudo-diverticulosis is a rare disease of unknown etiology. It is characterized by multiple pseudodiverticula with segmental or diffuse involvement of the esophagus. We report, the case of a 78-year-old male who suffered from severe dysphagia. Diagnosis of esophageal intramural pseudo-diverticulosis was based on endoscopic and radiologic explorations. Histological analysis of esophageal mucosal biopsies has shown the presence of candida albicans. Antifungal treatment leads to spectacular improvement of dysphasia. Subsequently, the patient presented a cardio-respiratory failure and died despite adequate treatment.

Henoch-Schönlein purpura is an IgA-mediated immune vasculitis which is characterized by purpuric lesions and osteoarticular, intestinal and sometimes renal manifestations. The histopathological substrate of this entity is leucocytoclastic vasculitis (LCV) with IgA deposits seen on immunohistochemistry. We here report the case of a 27-year-old woman with abdominal pain and cutaneous purpura. Upper and lower endoscopic exploration showed purpuric lesions in the rectum but not in the stomach. Skin biopsy revealed LCV. IgA deposits were seen only in gastric mucosa. The patient was treated with corticoids which led to improvement of both the cutaneous and digestive symptoms. This case suggests that gastrointestinal biopsies of both normal and abnormal mucosa should be taken in Henoch-Schönlein purpura, especially in patients with atypical forms.
