Transluminal removal of a giant fibrovascular polyp of the esophagus.

Giant fibrovascular polyps of the esophagus are rare benign tumors that originate at the hypopharynx or the upper third of the esophagus. Because of the indolent and benign nature they are mostly discovered when very large with symptoms like dysphagia or regurgitation of the polyp into the mouth which can cause asphyxia and dead. The removal of these polyps is obligatory. Although more than 100 cases of giant fibrovascular esophageal polyps have been described in literature so far, the approach for removal is not yet standard and needs a customized use of medical technology from different disciplines. We present the case of a 42 year old man in whom a giant polyp was removed transorally by a combination of instruments and materials from different disciplines (gastroenterological, surgical and laryngological).

Intussusception of the small intestine caused by a primary melanoma?

Although the gastrointestinal tract is a fairly frequent site of melanoma metastases, reports of small bowel intussusception caused by melanoma are very rare. We report the case of a 77-year-old man who was admitted to our hospital with epigastric pain, melena and anaemia. After clinical examination, laboratory evaluation and radiological work-up the diagnosis of a jejunal intussusception was made. Exploratory laparoscopy revealed a large tumour arising from the jejunum, approximately 20 cm distal to the angle of Treitz. Small bowel resection with an end-to-end anastomosis was performed. Histological examination showed an intestinal melanoma. There are different theories concerning the origin of malignant melanoma in the small bowel. Although the small and large intestines normally contain no melanocytes, these cells have occasionally been found in the alimentary and respiratory tracts and even in lymph nodes, which supports the theory of a primary origin of melanoma at these sites. Since this was a solitary intestinal lesion and there was no history of cutaneous melanoma, we conclude that this could be an example of a very rare primary melanoma of the small intestine.
